The article presents the results of studies to facilitate the starting and reduce the duration of the warm-up of automotive internal combustion engines in conditions of low ambient temperatures. The factors affecting the start of a diesel engine are considered. It was noted that in order to improve the starting quality and reduce the warm-up time of a diesel engine at low ambient temperatures, it is advisable to use a thermal accumulator of the phase transition for heating the intake air. In order to determine the influence of the air intake temperature at the time of cranking the engine until the start of the diesel engine, fuel efficiency and emission of harmful substances in exhaust gases during warming up in idle mode, experimental studies of the 1.9TDI ASV diesel engine produced by Volkswagen AG were conducted.
