Control device for a gasoline-powered direct injection internal combustion engine
First Claim
Patent Images
1. A control device for a direct-injection gasoline internal combustion engine having sensors for sensing operating parameters and a plurality of metering and actuating devices for controlling a fuel mass, a fuel pressure, an air mass and an ignition, the control device comprising:
- a signal processing unit for controlling a fuel injection operation in at least one of a stratified mode and a homogenous mode depending on an operating zone of the internal combustion engine, wherein the signal processing unit;
determines a required engine torque;
converts the engine torque into at least one value related to a fuel mass flow value, an air mass flow value and an ignition angle value;
converts the fuel mass flow value into a first injection time value for the homogenous mode;
converts the fuel mass flow value into a second injection time value for the stratified mode; and
forms control signals for at least one fuel injection valve, a throttle valve actuator and an ignition system.
