Abstract:
A method of operating an internal combustion engine having a combustion chamber with a piston and a spark plug, comprising during a first mode, bringing the temperature of the combustion chamber to auto-ignition temperature by adjusting engine operating conditions and producing auto-ignition in said combustion chamber without requiring spark from said spark plug; and during a second mode, bringing the temperature of the combustion chamber close to auto-ignition temperature by adjusting engine operating conditions, forming a small cloud of stratified air-fuel mixture near said spark plug, igniting said fuel cloud by a spark form said spark plug, and then causing cylinder pressure to rise, thereby producing auto-ignition at other sites in said combustion chamber wherein said first mode is implemented in a first operating range and said second mode is implemented only in a second operating range where engine speed and load are lower than said first operating range.
Abstract:
A direct injection spark ignition engine comprises a cylinder, a piston, a fuel injector arranged at one side of a center axis of the cylinder for directly injecting fuel into the combustion chamber, and a smoothly continuous lowered recess formed on a top surface of the piston surface. The recess has a first cross section along a first plane including the cylinder center axis and a nozzle end of the injector. The first and second lower contours are smoothly connected with each other through a lowest point of the first cross section. The first lower contour is located at the one side of the cylinder center axis. The second lower contour is at the other side. The first contour has a larger radius than a radius of the second contour. Accordingly, the fuel spray having greater movement energy may impinge the recess at a regulated impinging angle.

Abstract:
A control device for a direct injection engine having a catalyst provided in an exhaust passage for converting exhaust gases and an injector for injecting fuel directly into a combustion chamber, includes a temperature state identifier for judging the temperature state of the catalyst, a load condition detector for sensing engine load conditions, and a fuel injection controller for controlling fuel injection from the injector. The fuel injection controller performs quick light-off control operation by causing the injector to inject fuel in one-time injection mode during a compression stroke in a specific low-load operating range of the engine when the catalyst is in its unheated state where its temperature is below its activation temperature, and switching the mode of fuel injection to intake-compression stroke split injection mode in a specific high-load operating range of the engine.
