Fuel Injection Equipment, Internal Combustion Engine, and Control Method of Fuel Injection Equipment

摘要

A fuel injection equipment to control the instability of combustion when the airflow is weak, and improve the fuel cost. A fuel injection equipment for an cylinder injection type and spark ignition type internal combustion engine that injects gasoline directly to a combustion chamber, wherein the top angle at the point of fuel spray in the pressurized atmosphere of absolute pressure 0.5MPa is from -10° to 10°. Further, the fuel is injected at the compression stroke of the internal combustion engine which installs the fuel injection equipment, and said internal combustion engine is started.
