In-cylinder fuel-air ultrahigh pressure high-mix direct injection detonation combustion promotion internal combustion engine master device

Abstract

The invention discloses an in-cylinder fuel-air ultrahigh pressure high-mix direct injection detonation combustion promotion internal combustion engine master device which comprises a cylinder, a piston, an admission passage, an exhaust passage, a crank, a turbine, a small supercharger, a large supercharger, a high-energy fuel tank, a medium pressure fuel pump, a pilot injection medium pressure feed high-temperature highly rarefied combustion input control system, an ultrahigh pressure fuel pump and a post injection high pressure feed high-temperature highly rarefied combustion input control system. A novel combustion mode includes that in-cylinder fuel-air high pressure airflow is directly injected, stirred and highly mixed, ultrahigh supercharged macro-energy high pressure high-speed jet flow kinetic energy turbulent flow is violently stirred, reaction ratio, mixing ratio and vaporization ratio are ultrahigh, and accordingly, combustion is certainly promoted. An external tail gas treatment device is omitted, various fuels can be universally used, high-speed combustion is promoted and stimulated by high pressure and high temperature, and the combustion promotion combustion-supporting system realizes unconventional highly rarefied high-speed stable, forced, complete and clean combustion, direct injection, stirring and high mix of the in-cylinder fuel-air high pressure airflow, and ultrahigh reaction ratio, mixing ratio and vaporization ratio.
