dc.description.abstractEnsuring the optimal initial parameters of the working cycle by improving the turbocharging system is one of the reserves for increasing the efficiency of marine internal combustion engines. Reducing the power consumed by the charge air turbocharger provides a power reserve for the turbocharger turbine, which can be transferred to the engine shaft or used to drive an electric generator. There are several approaches to charge air cooling, one of them is to use thermopressor technologies in the ICE turbocharging system which allows two processes to be combined: contact cooling of the charge air and pressure increase, which reduces the compressor power consumption. A thermopressor can be used to carry out these processes. The authors of the research analyzed water spray systems and developed a scheme for improving the air-cooling systems of ship engines, which consists in the use of water injection into a thermopressor. This scheme allows to reduce the charge air temperature to 50...67 degrees, increase the relative increase in air pressure at the thermopressor outlet by 2...10%, and, accordingly, reduce the power of the engine turbocharger.uk_UA
