Trucks with gross weight of 40 t and different engines are taken as objects of research, which are indicated as objects A, B, C in the following text. The operating modes of the engine in terms of fuel economy and reduction of environmental damage are given in the example of 3 cars. It is stated that when power usage grade is U = 0.8 and engine operates in 70-80% of its maximum engine speed a fuel consumption and environmental damage is reduced. The article summarizes the following: operation of the engine with power usage grade around 0.8 in the city conditions can be provided by using engines with appropriate power i.e. a car with big engine power is not necessary in the city conditions in terms of fuel economy and environment protection.
