  • Fuel injection system having pre-injection and main injection
    Publication number: 20010039935
    Abstract: The angle of fuel spray at the time of pre-injection is set to a wider angle of spray and the angle of fuel spray at the time of main injection is set to a narrower angle of spray. The pre-injection timing is set so that when fuel spray after the pre-injection is diffused in a cylinder and stratified, the stratified fuel spray is ignited by a rise in the pressure in the cylinder in association with movement of a piston from the bottom dead center to the top dead center. The main injection timing is set so that when the spray stratified by the pre-injection is burned, the fuel spray injected by the main injection passes through the combustion zone while being ignited in the combustion zone, reaches a combustion chamber of the piston, and is burned in the combustion chamber.
