Abstract
Introduction. The air temperature in the intake manifold is used by an electronic engine control unit to adjust the injection time of the fuel injector top. The intake air temperature is variable and depends on the operating conditions of the vehicle. When air intake temperature decreases, the duration of the nozzle opening pulse increases and, conversely, as air intake temperature increases, the duration of thenozzle opening pulse decreases.Materials and methods. The paper demonstrates the analysis of the air temperature effect in the intake manifold of the engine on the duration of the injector opening pulse while the engine is idling and when the vehicle is m...
