    摘要: An engine control system for an internal combustion engine of a type changing a fuel injection timing between a first injection timing to achieve homogeneous charge combustion and a second injection timing to achieve stratified charge combustion comprises at least one sensor and a controller for controlling fuel injection timing and quantity. The controller selects one of homogenous combustion mode and stratified combustion mode in accordance with the engine operating condition sensed by the sensor, calculates the fuel injection quantity for the selected combustion mode, and enables a start of a homogeneous mode injection of fuel to a given cylinder of the engine at the first injection timing for the homogeneous mode if calculation of the homogeneous mode fuel injection quantity for the given cylinder is finished prior to the first injection timing for the given cylinder. If the calculation of the fuel injection quantity for the given cylinder is not finished yet, the control system performs a stratified mode injection of the fuel to the given cylinder at the second injection timing.

    摘要: What is disclosed is a vehicle engine control system responsive to a change between a first request for homogeneous charge combustion and a second request for stratified charge combustion. A spark-ignition cylinder-injection internal combustion engine has cylinders, each performing an intake phase, a compression phase, a power phase, and an exhaust phase. The cylinders each, when rendered operable in a first mode, experience first fuel injection at a first fuel injection timing during intake phase thereof and first spark ignition at a first ignition timing to initiate homogeneous charge combustion. The cylinders each, when rendered operable in a second mode, experiences second fuel injection at a second fuel injection timing during compression phase and second spark ignition at a second ignition timing to initiate stratified charge combustion. A fuel injection manager is operable to set one of the first fuel injection and second fuel injection for the cylinders in a predetermined sequential order in response to one of the first and second request. A spark ignition manager is operable to set one of the first spark ignition and second spark ignition for the cylinders in the predetermined sequential order in response to one of the first fuel injection and the second fuel injection that has been set to each of the cylinders.
