Diesel engine of indirect injection type combustion chamber equipped with direct injection type combustion chamber

摘要

The present invention relates to an indirect injection type combustion chamber for a diesel engine having a direct injection type combustion chamber, and more particularly, to a direct injection type combustion chamber having a direct injection type combustion chamber for improving the thermal efficiency by reducing the heat load .;In the indirect injection type combustion chamber for a diesel engine, the injection nozzle provided in the indirect injection type combustion chamber is raised to the same level as the injection pressure of the direct injection type injection nozzle to be installed in the cylinder head combustion chamber, A main combustion chamber such as the direct injection type combustion chamber is formed on the upper surface of the piston and a passage is formed in the sub combustion chamber so that the injected fuel passes through the sub combustion chamber and quickly reaches the main combustion chamber.;As described above, in the present invention, since the injection nozzle of the indirect injection type combustion chamber is raised by the injection pressure of the direct injection type injection nozzle, the vortex is strong and the mixing is facilitated.;Therefore, while taking advantage of the advantages of the indirect injection type combustion chamber, the disadvantage of the direct injection type combustion chamber is that the thermal efficiency is improved, and the combustion is completely burned to effectively reduce the soot.
