Apparatus using air jet nozzle in front of inlet manifold at diesel engine.

摘要

Vehicles equipped with diesel engines are inevitably caused by incomplete combustion due to inadequate combustion due to excessive injection of fuel at the start and acceleration, leading to serious air pollution problems. have.;In order to solve this problem, an intercooler is installed, and an engine equipped with an ECU, such as a gasoline engine, has been developed and put into practical use. However, such an engine can reduce the generation of smoke, but has a problem of degrading acceleration performance. to be.;This design is based on Bernoulli's principle, and installs a nozzle to inject high pressure air, which is supplied separately in front of the inlet manifold, to increase the air intake by using the pressure difference caused by the high pressure air injection and at the same time separate high pressure air. Pressurizes the air going into the cylinder to pressurize to increase the density of the air, and supercharges the combustion even at 2000 rpm or below at idle, which is the zone of the engine speed at which soot occurs most. With enough air, the best combustion condition is achieved, which is characterized by an increase in power output and fuel saving as well as a reduction in smoke.
