Title: Combustion chamber of direct-injection internal-combustion engine
Inventor: KAWAGE YUKIO
IPC: F02B3/06
Filed: 1982-06-21
Abstract: PURPOSE:To improve combustion performance and blue white smoke concentration, by providing cavity parts to the peripheral wall face of a combustion chamber in a position opposite to a fuel injection nozzle jet and forming flange parts constituting a ceiling face in an upper part of the cavity parts. CONSTITUTION:Cavity parts 2 are formed to the peripheral wall face of a combustion chamber 1 respectively in a position corresponding to each jet of a multi-hole type fuel injection nozzle. Flange parts 3 constituting a ceiling face are provided to an upper part of the cavity parts 2. At low revolution of an engine, a reach distance of atomization of fuel is increased by the depth of the cavity part, and combustion is promoted. While the generation of a bad odor of exhaust gas and blue white smoke can be prevented. Also at high revolution, existence of the cavity part 2 can promote mixing of a fuel particle with high temperature air and maintain a good utilization factor of air.
