Title:
INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2016/035276
Kind Code:
A1
Abstract:
An object is to enable stable diesel combustion in an internal combustion engine using a fuel having a relatively high self-ignition temperature. In the internal combustion engine, pre-injection and ignition of pre-spray fuel are performed, and thereafter main injection is performed to cause a portion of main-injected fuel to be burned by diffusion combustion. Injection ports of a fuel injection valve are provided in such a way that the quantity of the main injected fuel injected to a predetermined region defined by a predetermined angle equal to or smaller than 90 degrees about the fuel injection valve from the location of an ignition device in the direction of rotation of the swirl is relatively small.
