四、汽车燃料经济性试验方法(一)试验目的燃料经济性是汽车主要性能之一。它对汽车运输成本有较大的影响。因此在汽车设计、试验和使用中都给予特别注意。燃料经济性是汽车在给定的条件下行驶的燃料消耗;它与发动机工作的经济性和汽车的结构参数(重量、传动系速比、传动效率和流线型等等)以及行驶条件(速度、道路条件等)等有关;因此试验研究燃料经济性时,应该全面考虑上述因素的影响。
Fourth, the automotive fuel economy test methods (A) the purpose of the test Fuel economy is one of the main performance of the car. It has a greater impact on the cost of motor transport. Therefore, special attention is given to the design, testing and use of the vehicle. Fuel economy is the fuel consumption of a car traveling under a given condition; it depends on the economy of the engine operation and the structural parameters of the vehicle (weight, transmission ratio, transmission efficiency and streamline, etc.) as well as driving conditions (speed, Conditions, etc.) and so on; Therefore, the pilot study of fuel economy, we should fully consider the impact of the above factors.
