Abstract
Presented are the results of experimental studies of the heat treatment system of a vehicle gasoline engine, which is heated to operating temperatures on gasoline, and subsequent operation on liquefied oil gas. The main element of the heat preparation system is a phase transition heat accumulator. The research task to be solved is to minimize the time of heat preparation of the vehicle gasoline engine and, therefore, to reduce gasoline consumption in warm-up modes. To ensure remote registration of vehicle parameters and control of heat preparation processes, an information system for monitoring and control of heat preparation processes of a vehicle engine with a heat accumulator was developed and used. During the research, a gasoline-powered vehicle was used with additionally installed gas equipment. The use of a phase transition heat accumulator in the heat preparation system of a vehicle gasoline engine (operating both on gasoline and on liquefied gas fuel) has confirmed a significant improvement in fuel economy. For this, the engine heat preparation should be carried out immediately before starting from an additional heat source to the coolant temperature in the cooling system up to 50° C. The research results have confirmed the capabilities of the system under study to significantly reduce the time of heat preparation and reduce the vehicle gasoline engine fuel consumption running on gasoline and liquefied gas fuel under operating conditions. The phase transition heat accumulator in the heat preparation system of a vehicle gasoline engine (operating both on gasoline and on liquefied gas fuel) reduces the time required to heat the coolant to 50° C and gas consumption to ensure the transition to gas fuel when using various modes (options) of heat preparation in operating conditions.
