Racing system (special electronic and electromechanical system for cutting-edge technologies in F 1, MotoGP and WRC tournaments) Ma Ruili Electronic Systems Company is headquartered in Corbetta, Italy, and its main business is automotive electronics. Its six production bases, three R&D centers and five application development centers are located in Italy, France, Germany, Spain, Brazil, Mexico and China. The main products are divided into three areas: instrument cluster, body electronics and wireless communication navigation system.
Instrument cluster: As a traditional business of electronic system department, instrument cluster can provide drivers with information such as vehicle speed, rotation speed, fuel quantity and water temperature. Ma Ruili Electronic Systems Department develops and produces embedded monochrome (dot matrix) displays or dashboards combined with increasingly popular color displays. At the same time, it also produces more complex instruments with higher configuration, which can perform gateway functions.
Body Electronics: Electronic Systems Department develops and produces electronic modules with the following functions: fuel control and distribution, external lighting control, anti-theft, remote control, wiper control, tire pressure detection and window anti-pinch lifting control. It also has a considerable professional level in the field of airborne systems, and can define and verify functional features (infographics).
Long-range wireless communication system and navigation: Ma Ruili Electronic Systems Department provides long-range wireless communication components for Fiat Group (Fiat, Alfa Romeo, Lancia, Maserati) and PSA (Peugeot and Citroen). In order to provide remote wireless communication products with standard components and full information coverage, Ma Ruili Electronic Systems Department decided to develop four different types of products: high-end information navigation platform, wireless navigation, EasyRoad and multimedia entertainment navigation system.
The new high-end information navigation system is a device that integrates entertainment, navigation, wireless communication and telephone functions. It is a natural progress of the existing high-end navigation platform, and its improvement is mainly reflected in having a hard disk even larger than 30G (for storing music and maps covering the whole of Europe), and a 3D processor and solution that can better improve the sound quality of the system. On the other hand, wireless navigation is designed to provide competitive portable initial equipment. The special feature of this product is that Bluetooth application (instead of integrated telephone module) can connect the user's mobile phone and SD card reader. Ma Ruili's experience in electronics and information navigation in the automotive industry has led to the development of EasyRoad, a hand-held portable navigation device with a 3.5-inch color display and a 20-channel GPS Sirf StarIII receiver. This is very convenient to operate (the map is loaded on 5 12MB SD card) and use multimedia functions. It can not only navigate by satellite, but also read movies, pictures and photos. Besides, it can also listen to music. The multimedia entertainment navigation system is still under development.
This is a highly integrated low-cost system, but Blue &; I/Blue & ampMe navigation is also used for entertainment, navigation and safety (emergency phone box, which will automatically dial out emergency calls when the car collides or rolls over). Ma Ruili Group Car Lamp Company was founded in 1999, formerly a joint venture between Bosch Co., Ltd. and Ma Ruili Co., Ltd., at that time, both parties held 50% shares. 200 1 Automotive Lighting Company reorganized with Seima Group (a leading enterprise in automotive aftermarket lighting production), and acquired the shares held by Bosch Company in 2003 to become a wholly-owned enterprise. Ma Ruili Group Automobile Lamp Company specializes in product development, production and sales in the technical field of automobile lamps, including headlights, taillights, fog lamps, headlight cleaning systems, leveling systems, electronic components and high-position brake lamps.
Customer orientation and global operation are the keys to the success of Ma Ruili Auto Lamp Company: it has more than 65,438+0,000 employees in more than 20 countries around the world. In Europe, R&D centers located in Reutlingen, Germany and Tolmezzo, Italy are devoted to the continuous innovation and development of front and rear lights, and some local R&D centers have branches in three continents and always keep close contact with local customers. With people paying more and more attention to driving safety, headlights and fog lights play an increasingly important role in headlight system, which also embodies the personalization of design and improves the aesthetics of the car body. Headlights and fog lamps play an important role in defining the appearance and identity of a car no matter day or night, which is why the modeling department of the car lamp company cooperates closely with various car manufacturers. Headlight Company of Ma Ruili Group took the lead in releasing xenon lamps at 199 1, leading headlight technology into a new realm. In 2003, the car lamp company installed the dynamic adjustment lamp on the car for the first time, which took a big step towards the adaptive forward lighting system (AFS).
In 2005, headlights with infrared modules appeared for the first time in the world. In 2006, headlights with complete adaptive forward lighting system (AFS) were put into use for the first time, which can be adjusted according to road and weather conditions. The next invention is the application of light emitting diode (LED) technology in front and rear lights, which also provides designers with a broader design space and saves energy. In 2005, the car light company began mass production of taillights using LED technology for the first time. Ma Ruili Power System Company is a company that produces engine parts for automobiles, motorcycles and light buses. Its headquarters is located in the historic Timavo Street in Bologna, Italy, where Weber carburetor was born as early as 1920. The company has 65,438+04 R&D centers and 8 production bases on four continents: Europe (French, Italian and German), the United States (Farmington Hillsand Sanford), Brazil and China (Shanghai and Wuhu). Its main products are gasoline and diesel engine control systems. Ma Ruili Power System not only controls the hardware of engine electronic control unit, but also produces supporting software. At the same time, it also provides automobile manufacturers with some vital parts that affect engine performance and emissions: fuel injector, intake manifold of gasoline engine, intake manifold of diesel engine and throttle body.
Ma Ruili Power System Company is in the leading position in the key areas of environmental protection by using automobile technology, such as the application of gasoline engine in-cylinder direct injection technology and flexible fuel technology. Flexible Fuel Technology (SFS) was launched in Brazil in 2003. This technology allows cars to use ethanol, a fuel extracted from plants and widely produced and used in Brazil. The addition ratio is 0 to 100%. In 2007, all new cars in Brazil will use flexible fuel technology. Meanwhile, Ma Ruili is the market leader in Brazil, with a market share of 58%. Ma Ruili has also developed flexible fuel technology using blended fuels. This technology uses a special microprocessor in the engine control circuit board, which enables the automobile engine to add four different fuels (pure gasoline, gasoline mixed with 22% ethanol, pure ethanol or natural gas).
The gearbox management system controls the automatic gearbox, such as the computer-controlled hydraulic shift mechanical gearbox from F 1, which not only satisfies the driver's comfort but also reduces the fuel consumption. Computer-controlled hydraulic shift mechanical gearbox is not only used in small and medium-sized engines, but also installed in several very famous cars, such as Ferrari, Lamborghini and Aston Martin. The main vehicle manufacturers of Ma Ruili Power Systems are all over Europe and America, and its market share in Brazil has always been among the best. Its customers also include emerging companies in China and India, such as Chery, Suzuki Maruti and Tata. Piaggio, Ducati and Davidson among motorcycle manufacturers are also customers of Ma Ruili. Ma Ruili Suspension System Company designs and produces automobile chassis modules and parts. Headquartered in Turin, it has branches in other Italian cities, Poland, Brazil and the United States.
Ma Ruili Suspension System Company includes three main product lines: chassis, shock absorber and SDC (electronically controlled shock absorber). Suspension products range from individual parts (rocker arm, cross beam, drive shaft, strut, brake disc and brake drum) to assembly parts (wheel assembly, half axle). The structural design and testing department can meet the technical requirements of customers, and can develop or improve the existing drawings of customers according to their requirements. Master the main technologies in the automobile industry and care about suppliers and partners, so that our suspension parts have extensive resources and control the quality and performance well.
Product innovation includes new suspension concepts, such as F.L.E.C.S (soft connection, advanced flexible chassis) and T.O.R.C.S (torsion bar flexible chassis), which are simple to calibrate but have the best dynamic performance. These systems will become substitutes for traditional suspensions of automobile manufacturers. The shock absorber product line includes "structural" shock absorber (McPherson is the foundation of chassis) and "traditional" shock absorber (all others are applicable), and also provides air springs for the market. The latest SDC product line (SDC, * * * Vibration Control) is a kind of shock absorber system, which is based on an electronically controlled solenoid valve to change the actual time for hydraulic oil to pass through the shock absorber. This product greatly improves the dynamic performance of the vehicle, but also reduces the design work of the suspension system, providing better comfort and "power". Ma Ruili Exhaust System Co., Ltd. is a company that provides high-quality and high-performance exhaust systems for automobile factories and motorcycle factories. It has seven bases in the world, including three in Europe (Italian, Spanish and Polish), one in South Africa, two in South America (Brazil and Argentine) and one in Asia (China). All bases have their own production plants, and four of them have their own R&D centers (Italian, Spanish, Brazilian and China).
Exhaust system company is committed to two aspects of research: on the one hand, it is to reduce pollutants in exhaust gas (through three-way catalytic device), on the other hand, it is to reduce noise (through muffler system). In order to meet the increasingly stringent emission regulations, the three-way catalytic device in the exhaust system was adjusted to reduce pollution. In 2005-2006, Europe began to implement Euro 4 emission regulations, while the stricter Euro 5 regulations will be implemented in 2009, and we will also make more innovations to make our products conform to these regulations. For example, for diesel engines, we have designed an anti-particle filter (compact system) in the engine compartment, and will further upgrade the diesel engine emission system by using other methods to reduce nitrogen oxides, such as SCR (selective catalytic converter with Ad Blue additive). Reducing noise is the goal that everyone pays attention to. According to customers' requirements, Ma Ruili Exhaust System Company uses its advanced technology to provide customers with a wider range of noise reduction products. Innovative solutions are carried out at the "hot end" and "cold end" of the exhaust system at the same time, which includes using new technical solutions and new manufacturing processes to improve quality, reduce weight and save costs. The racing department of Manieti Ma Ruili Group is responsible for the design, production and technical sales support of engines and related software and hardware products in various competitions. The company is headquartered in Corbetta (Milan), Italy, with production bases in Venaria (Turin) and Bologna, Italy, and R&D centers in France, Britain, the United States, Brazil and Japan.
An elite team of more than 65,438+000 professional engineers and technicians has made Magnetti Ma Ruili a super team in the bidding competitions of F65,438+0, WRC, MotoGP, Superbike, GP2 and FIA GT. In response to these events, Manieti Ma Ruili Company developed and manufactured some special electronic and electromechanical components, especially the engine control system and data acquisition system. At the same time, it also provides display, automatic measuring and recording sensor system, engine, voltage regulator, ignition coil, sensor, nozzle, pressure sensor, fuel pump and application software.
Since 19 19, Manieti Ma Ruili Company has actively participated in various motorcycle races, which is closely related to Ma Ruili Company's great enthusiasm for innovation, and the competition is a perfect interpretation of this passion. Manieti Ma Ruili is a leading enterprise in Brazil and even the world, and it took the lead in developing SFS○R technology, which allows alcohol, gasoline or a mixture of two fuels in any proportion to be used in the same car.
After four years of research and an investment of 9 million reais (about 3 million US dollars), dual-fuel technology was realized in March 2003, benefiting thousands of Brazilians, among which environmental benefits are the most important. Since the introduction of SFS○R (flexible fuel software sensor), the choice of two fuels can be decided by the driver himself.
SFS○R is a powerful computing software, which is placed in the electronically controlled injection module, also called electronic control center or electronic control unit (CPU). SFS○R can identify and quantify the mixed fuel of alcohol and gasoline in the fuel tank by using the information received from sensors all over the fuel injection system, such as λ sensor, engine temperature, vehicle speed, rotational speed and knock sensor.
Electronic control unit (ECU)
With this information, the software can determine the exact amount of fuel injected into the engine and the best ignition time for the spark plug to ignite the mixture. The first flexible fuel system appeared in the United States of 199 1, but the system needs to add a physical sensor to identify the fuel, which will increase the price of the whole vehicle. Even so, due to the water content of the fuel, the system cannot be used in Brazil. In contrast, SFS○R is technically feasible without installing physical sensors.
Congenital advantage
We are optimistic about this system because it has natural advantages. The fuel used in this system is alcohol, which is produced in Brazil and contributes to the trade balance. Alcohol combustion produces less carbon monoxide and carbon dioxide than gasoline, which can provide more power for the engine. Because the two fuels can be mixed in any proportion, the system ensures that the owner can choose the mixing proportion of the fuels according to the supply and price of the two fuels.
Four fuel flexible fuel technology
After the introduction of SFS○R technology in Brazil for the first time, Manieti Ma Ruili Company invented a new TetraFuel○R system.
The TETRAFUEL χ R system of Manieti Ma Ruili Company extends the fuel management of a single ECU, enabling it to manage four different types of fuels, so that gasoline, gasoline alcohol (gasoline mixed with 22% alcohol), pure alcohol or CNG (compressed natural gas) can be selected as the fuel in the same vehicle.
Advantages of fuel technology
TetraFuel○R technology not only promotes the export of Brazilian cars, but also greatly reduces the conversion/recovery cost of using CNG fuel. TetraFuel○R technology includes the control function of gas fuel in the original equipment, so there is no need to add a series of independent electronic and electrical equipment in the modification as it is now. TetraFuel○R system adopts the chip developed by Manetti Ma Ruili himself, which can optimize the control of gasoline and natural gas simultaneously with a single ECU.
Tetrafuel ○ r —— The technology of controlling four fuels with one ECU can realize the use of gasoline, alcohol, gasoline alcohol or CNG (compressed natural gas) on the same vehicle. Different from the existing products on the market, Tetrafuel○R does not modify the engine, but integrates a low-pressure system, which can effectively improve economy and reduce carbon dioxide emissions. The system can choose the best fuel according to various driving conditions, and it does not need to switch equipment when using, and will not cause power loss.
Four fuel companies. Integrated intake manifold assembly
Liquid fuel injector
This system provides an important cost optimization method for automobile manufacturers. Automobile manufacturers can provide the same engine layout for all MERCOSUR countries or other continents, thus integrating the production methods and equipment in the export market and the domestic market.
TetraFuel○R technology can automatically select fuel for various driving situations, achieving the best balance between power and fuel economy. In addition, the TetraFuel○R system of Manieti Ma Ruili Company is based on a fully integrated low-pressure system, instead of being modified as the existing conversion system, which can greatly reduce the emission of pollutants, especially greenhouse gases, such as carbon dioxide.
TetraFuel○R technology developed by Manieti Ma Ruili Company is 100% in Brazil, but it can be extended to other areas facing greater environmental pressure in reducing the overall pollution emission level of automobiles, such as North America, China and Europe.
