Estimating the term…
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.
An internal combustion engine of which fuel is injected directly into a cylinder, and air-fuel mixture formed in the cylinder is ignited;
An internal combustion engine of which fuel is injected directly into a cylinder, and air-fuel mixture formed in the cylinder is ignited;
An internal combustion engine of which fuel is injected directly into a cylinder, and air-fuel mixture formed in the cylinder is ignited;
An internal combustion engine comprising a fuel injection valve which injects fuel directly into a cylinder and an ignition apparatus which ignites air-fuel mixture twice or more, wherein said engine further comprising:
An internal combustion engine comprising a fuel injection valve which injects fuel directly into a cylinder and an ignition apparatus which ignites air-fuel mixture twice or more, wherein a first ignition timing is first determined, and then a fuel injection timing is determined, and a second and later ignition timings are determined if necessary.
