Ensuring 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.
