Direct injection type internal combustion engine

摘要

The invention relates to an internal combustion engine which injects fuel directly into a cylinder 104 and ignites air-fuel mixture formed in the cylinder, wherein
each fuel injection of said internal combustion engine comprises a lead spray 105 which moves faster and a main spray 106 which moves slower,
the lead spray 105 is oriented towards an ignition plug 114, and
the air-fuel mixture made by pre- and main sprays is ignited twice or more. This invention of the above configuration can provide a simple and inexpensive direct cylinder injection type internal combustion engine which reduces abrasion of electrodes and consumption of electric power while assuring stable fuel combustions even when ignition timing is retarded.
