◆ Note 1: Be careful when modifying air conditioners.
It is not recommended to modify the car air conditioner because the original air conditioner is matched with the car engine. If you modify it at will, it will affect the performance of the car.
◆ Note 2: The air conditioning temperature should not be too low.
Choosing the appropriate air conditioning temperature is the first step of air conditioning maintenance. Because of the hot weather, many car owners like to set the temperature too low, which will affect their health. In general, the difference between the inside temperature and the outside temperature should be 5℃ to 6℃, that is, the optimal temperature of air conditioner is 18℃ to 25℃.
◆ Note 3: Control the direction of air outlet.
Those of us who think we have rich knowledge of physics must remember the principle that cold air sinks and hot air rises. Don't forget to learn and use it. Principle of air outlet of automobile air conditioner: when air conditioner is turned on, the air outlet is upward, and when heating is turned on, the air outlet is downward.
Turn off the air conditioner properly when driving. Using air conditioner for a long time will make the condenser pressure too high and cause losses to the refrigeration system. ◆ Note 5: Turn on the large air volume appropriately.
Afraid of noise, how long have you been enjoying the breeze and drizzle in a small air volume? Let it properly sing a song "river of no return"! Air-conditioning will suck in a lot of dust when it is used, and blowing strong wind regularly can blow out the floating dust on the inner surface of the air duct. The simplest method is the most effective.
◆ Note 6: Turn off the air conditioner when driving at low speed.
Turn off the air conditioner as much as possible when driving at a low speed, and don't let the engine run at a high speed to improve the efficiency of the air conditioner in traffic jams, which will shorten the service life of the engine and the air conditioner compressor.
◆ Note 7: Remember the switching procedure.
Turn off the air conditioner first and then turn off the engine, which can ensure that the vehicle will start only by the engine at the next start; On the contrary, the air conditioner that is not completely turned off will start the engine, so that high-load operation will damage the engine. Many car owners often think of turning off the air conditioner after the flameout. So turn off the air conditioner and then turn it off after every parking. It is best to start the vehicle for two or three minutes, and then turn on the air conditioner after the engine is lubricated.
◆ Note 8: Use the air conditioner for a long time under the scorching sun to slow down.
Vehicles parked in the hot sun for a long time have a high temperature in the compartment. In this case, do not use the air conditioner immediately after the vehicle is started. First, open all the windows to ventilate and let out the hot air. After the temperature in the car drops, close the window and turn on the air conditioner. In addition, the air conditioner should not be turned on and off frequently to avoid damaging the air conditioning system. Especially for pickup trucks, it is more important to avoid repeatedly switching on and off the air conditioner when loading in a short time.
◆ Note 9: Turn on the air conditioner in the car and try not to smoke.
Passengers should not smoke in the car when the air conditioner is turned on. If you smoke, please adjust the ventilation control of the air conditioner to the external circulation position. It is also important to remember not to rest or sleep for a long time in a parked car with air conditioning. Due to the poor ventilation in the closed compartment with air conditioner when the vehicle is parked, if the air conditioner is turned on to rest or sleep at this time, it is likely that the harmful gas emitted by the engine will leak into the car, causing poisoning and even life-threatening.
2. Car maintenance tips How to clean the air conditioner
First, use air conditioning cleaning agent to clean automobile air conditioning:
In general, there is a pollen filter at the air inlet of the automobile air conditioner, which is used to prevent the dust from entering when the automobile air conditioner circulates outdoors. When cleaning the air conditioner, remove the pollen filter, put the foam cleaning agent into the air conditioner from the air inlet, and close the air outlet of the air conditioner to prevent the foam cleaning agent from flowing out of the air outlet. After these two steps are completed, start the car, turn on the air conditioner, and let the foam cleaning agent circulate inside the air conditioning system. This step will last for several minutes to ensure that the foam cleaning agent circulates to all channels of the air conditioning system. About 5 minutes, turn off the air conditioner and turn off the car. It won't take long for the dust to flow out of the cabinet from the air conditioning piping system.
Second, remove and clean the car air conditioner:
Another way of washing is disassembly and washing, which is much more troublesome than the first way. First, you have to take apart the dashboard and take out the evaporator of the air conditioner. The evaporator of an air conditioner that has not been cleaned for a long time must be covered with dirt and small Mao Mao. You have to brush carefully. This step is completed. Reinstall the air conditioner and wash it again in the first way. If you have more time, you will have to spend more money, and it will cost at least a few hundred yuan to dismantle and wash. Washing a particularly dirty air conditioner costs more than 1000 yuan. Therefore, the air conditioner of the car should be cleaned in time, and it should not be "hairy", which is both laborious and costly.
The first step is to clean the filter element, which is relatively simple. Step 2, open the storage box to find the condenser, spray cleaning agent to increase air cooling. If you think the air conditioner stinks, you can wash it yourself. This is actually not difficult.
1. Buy foam cleaning disinfectant: a bottle of "air conditioner cleaner for family car".
2. Preparation: find a place with fresh air (remember to clean the air, because the back of the air-conditioning partition should be removed), open the front cover, take out the air-conditioning partition at the air inlet in front of the passenger seat, open all the windows, and prepare a cloth to wipe the air outlet;
3. Start cleaning: ignite, turn off the air conditioner, use external circulation, and the maximum air volume is 4. Remember that the wind should blow at the driver (that is, not at the feet), then insert the catheter of the cleaning agent, shake it vigorously at the air inlet in front of the co-pilot, and spray foam (you can spray the whole bottle by yourself). At this time, pay attention to the foam sprayed from the air outlet and be ready to dry it with a cloth at any time.
4. Wait: After the above steps are completed, let the wind be on, let it blow for about 10 to 15 minutes, then turn off the wind, turn off the fire, and let the dirty water leak from the drain pipe under the car, and wait for about a few minutes;
After a few minutes, there is a large area of sewage in the ground, which means that the air conditioning cleaning has been completed. The air conditioning partition will be installed and the air conditioning will be turned on by ignition. The air discharged from the air conditioner is already delicious. If it tastes bad, it's better not to try it.
These are some methods that can be used for reference. Don't never clean the air conditioner. After a long time, bacteria will grow, and then there will be a bad smell. Sunny days will be more troublesome. It is better to do this work in peacetime. Also save trouble in the future.
3. Small knowledge and skills of automobile energy saving
1, driving one day less every month. If private cars drive one day less every month, the national carbon dioxide emission can be reduced by 1.22 million tons a year, and the total energy consumption can be saved by 6 1 10,000 tons of standard coal.
2, carpooling, carpooling can effectively reduce the use of motor vehicles, save fuel and reduce exhaust emissions. 3, choose fuel-efficient models Generally speaking, family cars are more fuel-efficient than sports cars and sports cars.
The new car engine has good fuel-saving performance. Manual gear is not necessarily more fuel efficient than automatic gear.
If the transmission ratio design of the gearbox is unreasonable or the driver's skill is not up to standard, manual transmission is likely to consume more fuel than automatic transmission. 4. Choosing a lighter car color and interior can also reduce the absorption of heat, reduce the cooling load, and naturally save fuel.
5. If the shape is rounded and smooth as far as possible, the drag coefficient of the car body will be small and the fuel consumption will be significantly reduced. 6. Installing an economizer in the fuel circuit Experts said that when the fuel passes through the economizer, the magnetic splitting catalyst splits the long-chain alkaline fuel molecules into shorter alkaline molecules, making the fuel combustion more efficient.
This can save 5- 10% of the fuel cost; Eliminate the carbon deposition phenomenon of the engine and make its service life reach 6.5438+0.5 million kilometers; The engine power output is more stable; Harmful tail gas emission is reduced by 20%; The cost of purchasing equipment is about 1.500 yuan, and the fuel saved by driving 37,500 kilometers can be recovered. 7. Turbocharged economizer is suitable for all kinds of gasoline-fueled vehicles below 1.6 liter.
According to the principle of aerodynamics, the engine is changed from natural air intake to active air intake, which effectively increases the active density of oxygen molecules in the engine, promotes the full mixing and atomization of fuel and gas, achieves the best air-fuel ratio, and finally significantly improves the power of the engine. The device does not change the engine, does not affect the engine life, and can save fuel 10%.
8. Various automobile window films with high thermal insulation performance, such as heat absorbing film, reflective metal film, spectrally selective metal film, spectrally selective ceramic film, etc. All of them are equipped with automobile thermal insulation measures, which are especially useful in the long summer in the south, and can reduce the indoor temperature by 5- 10℃, which is beneficial to reducing the air conditioning load and fuel consumption and prolonging the service life of the air conditioner in the car. The cost of purchasing car film is about 65,438+0,000-2,000 yuan, and the investment can be recovered in 0.25 years, and the direct cost of 2000 yuan will be saved every 50,000 kilometers.
9. Maintenance of the air filter The function of the air filter is to purify the air entering the cylinder. If the refueling exceeds the standard or is too dirty, it will cause poor air and increase vehicle fuel consumption. 10, remove the carbon deposition combustion chamber, and increase the carbon deposition, which will easily lead to the spontaneous combustion of combustible mixture, leading to a decrease in power.
When removing the cover for secondary maintenance and other reasons, the carbon deposit on the top of the combustion chamber and piston should be carefully removed to reduce unnecessary fuel consumption. 1 1, battery activation, insufficient battery power will increase the fuel consumption of the whole vehicle.
The battery produced by regular manufacturers according to the standard can be "activated" once in the car for two or three months at the beginning of vulcanization, so that the capacity of the battery can be restored to more than 96%. It is easy to reach the design life (24-36 months) of the battery that is "activated" in this way. 12, maintenance muffler Although the muffler is to reduce noise, it also hinders the exhaust of waste gas and consumes some power.
If the muffler is damaged, it will further hinder the exhaust and increase fuel consumption. 13, check the spark plug spark plug is to introduce high-voltage electricity into the cylinder of the engine, generate sparks between the electrodes, and ignite the mixture.
The working state of spark plug, the size of spark plug gap and the amount of carbon deposit have direct influence on power and fuel consumption. 14. Regular maintenance of the engine requires regular preventive maintenance of the engine, because long-term engine misalignment will consume more fuel.
15. Use the lowest viscosity engine oil. Your car manual should state the lowest viscosity oil that can be used in your car. The lower the viscosity of engine oil, the more "labor-saving" and fuel-efficient the engine is.
16. Always keep the cooling water tank clean, change the water in the water tank in time, change the engine oil and "three cores" in time, and ensure the ventilation opening is smooth. Impurities accumulate in the water tank, insufficient engine oil will increase friction, and poor heat dissipation will affect engine efficiency and increase fuel consumption. 17, using gasoline detergent is more effective for cars that have been used for a long time; For cars, it just keeps the fuel system of new cars unblocked and the nozzle and intake valve clean, so that the fuel consumption of new cars can be kept at the best level for a long time, and generally it can save 3-5% of fuel.
18, don't change the tire size at will. Choosing a wider tire will increase the wheel resistance accordingly, so there is no need to increase the tire width unless it really needs extra grip, otherwise it will increase fuel consumption. 19, maintaining the dent in the car body will increase the airflow resistance encountered when the car is driving.
In addition, those flashy decorations will only increase resistance. 20, planning a good driving route Pay attention to planning a good driving route in advance, often going the wrong way not only wastes fuel, but also wastes time.
2 1, according to the road fuel-saving method, the load of the car and the slope of the road should be measured when going uphill, so don't use too much oil at once. Using low gear and braking when going downhill, on the one hand, can avoid excessive speed increase, on the other hand, can reduce the loss of braking.
22. When parking in traffic jam, it will be closed. Generally speaking, if the traffic jam lasts more than 5 minutes, or the blocked vehicle in front is missing, you should turn off the engine and wait. 23. Avoid driving at low speed for a long time. Only when the engine, accelerator pedal and gear are in tacit cooperation can the most economical and best power be output.
"Leading" or "lagging" gears will form "procrastination" and increase fuel consumption. Therefore, you should try to avoid low gear when driving. Once conditions permit, you should try to drive at high gear on the road and keep driving at a medium speed to save fuel.
24. Avoid overloading vehicles beyond the rated load. For every additional load of 1 kg, the fuel consumption per kilometer increases by 0.0 1. Therefore, you should try to reduce your own weight and get rid of some unnecessary "burdens" when driving in the city.
25. Don't overspeed For ordinary cars, 80 km/h is the most fuel-efficient speed. Increasing 1 km/h for the first time will increase your fuel consumption by 0.5%. 26. Cleaning the trunk of the trunk will increase the weight of the vehicle, and overweight vehicles will save more fuel when driving. Therefore, it is necessary to clean the trunk in time and reduce unnecessary items.
