Not long ago, BAIC Group and its 10 automobile unit including BAIC Futian donated 40 Futian Tuyano negative pressure ambulances to china charity federation. Foton Motor announced at the event that it would donate another 20 negative-pressure ambulances worth 7 million yuan to help Wuhan fight the epidemic.
Many people have been wondering, what is the difference between a negative pressure ambulance and an ordinary ambulance? In fact, the negative pressure ambulance is also called "Mobile N95", which shows that its protective performance is much better than that of ordinary ambulances. The author will combine Tuyano negative pressure ambulance to reveal the special features of negative pressure ambulance.
At present, Tuyano Negative Pressure Ambulance matches Cummins ISF of National 6 emission standard. 2.8 engine, displacement of 2.8L, maximum power 130kW, maximum torque of 360N.m, and acceleration of 100 km is only 19.2 seconds. It is the leading engine in the industry, with strong power and help. Every second counts.
Front and rear drive, matching four-wheel disc brake.
In terms of appearance size, the long wheelbase version of Tuyano is 5990×2000×2555/2585mm, and the wheelbase is 3750mm, which is the largest size of blue brand light passengers and can better meet the special configuration space and internal size requirements of negative pressure ambulances.
As for the body, Tuyano has adopted the facility style of European light passengers, which is more suitable for refitting ambulances. Many places in China have purchased a large number of ambulances from Tuyano, which proves Tuyano's excellent adaptability and reliability. We should know that the requirements of negative pressure ambulance for vehicles are much higher than those of our common ambulances, and the requirements for technical parameters such as frame structure, ventilation and sealing of the body are even higher.
The above picture shows the internal structure of the engine room, and the space is large to facilitate the arrangement of various equipment.
Negative pressure ambulance, also known as protective ambulance, is mainly used to transport patients with infectious diseases. There is a partition between the cab and the rear passenger compartment, which can avoid the contact between the driver and the interior of the compartment and reduce the risk of infection. The driver communicates with the rear cabin by radio. When it is safe, he can open the sliding window to transfer things.
There is a sliding door on the right side, and the tailgate is a double door, which cooperates with the exit pedal to facilitate access to the medical cabin.
The vehicle is equipped with negative pressure system, which consists of negative pressure controller, exhaust fan, pressure indicator, air high efficiency filter, air outlet assembly, air sterilization system and other components. On the one hand, powerful suction and exhaust equipment will make the medical cabin have a relatively low atmospheric pressure difference with the external environment, ensuring that the air in the car circulates according to the designed passage and will not leak casually; On the other hand, it will make fresh air flow from top to bottom, and protect medical staff as much as possible. The air in the carriage will be filtered by sterilization system and other equipment, and then discharged to the outside of the car.

The pressure inside the carriage is lower than that outside, and the air outside will naturally "desperately" run into the car. In order to ensure that the interior of the carriage is in a stable negative pressure state, great requirements are put forward for the sealing of the vehicle. Just like the common vacuum packaging bag in our life, even if the packaging is just a small hole, there is no pressure difference between inside and outside, and air can flow freely.
In addition, in addition to the negative pressure system in the vehicle, each negative pressure ambulance is independently equipped with a negative pressure isolation cabin for transporting infectious patients as shown in the above picture. It is like a small negative pressure ambulance, and its principle is basically the same as that we introduced above. On the one hand, the infected patients are isolated from the outside world, on the other hand, a negative pressure space is formed to control the air flow.
It can be seen from the negative pressure system introduced in this paper that the negative pressure ambulance has very strict requirements for vehicle space and sealing. It doesn't mean that a car can be modified into a negative pressure ambulance when it is taken out. Only when it reaches a certain standard can it maximize its value. Fukuda Tuyano shouldered this heavy responsibility by virtue of its strong adaptability, and delivered a negative-pressure ambulance with good quality and quantity in just 10 days, which made people see Tuyano's social responsibility. I believe that as more and more professional equipment is put into operation in epidemic areas, we will surely defeat the epidemic as soon as possible!
