    摘要： A fuel injector employed in a direct injection engine comprising a spark plug arranged on the top of a combustion chamber, a fuel injector located on said combustion chamber and an intake air control means installed on an intake manifold. A forward tumble air flow is formed in the combustion chamber by the intake air control means, and the fuel injector is available in two types; an annular (conical) spray type characterized by uniform density and a spray type characterized by high/low density. In the case of latter type, arrangement is made to ensure that the denser portion is placed face-to-face with the spark plug. Spray fuel rises along the wall surface of the combustion chamber on the intake side, and is carried to the spark plug by forward tumble air flow (called “tumble guide”) moving from the fuel injector to the spark plug. This allows stratified charge combustion to be performed in the operation range from low to high speed ranges, with the result that discharge of gas containing hazardous gas component such as THC is reduced and fuel economy is improved.

    摘要： Fuel-air mixture is supplied with stability to the neighboring area of an ignition plug without any effect on deflection of fuel spray due to the air flow (swirl/tumble) in a combustion chamber, and the deposition of fuel onto the side wall of a combustion chamber is reduced, leading to the prevention of occurrence of smoke. A fuel injection apparatus includes a fuel injection valve having a nozzle opening to a combustion chamber and an ignition plug. The fuel injection valve forms a fuel spray having different levels of average speed. The fuel spray has relatively high speed at least in half of a single cycle of a fuel injection, and after that, the fuel injection valve forms relatively low-speed fuel spray, and consequently, a fuel-air mixture including high-speed fuel spray is supplied to a neighboring area of the ignition plug.

    摘要： The present invention is intended to provide a control system for an direct injection internal combustion engine capable of effectively reducing the amounts of both HC and NOx exhausted from a combustion chamber during a period from the start of the engine operation to the stop of the engine operation. It comprises an external EGR passage (11) for returning a part of exhaust gas from an exhaust pipe (10) to an intake pipe (5), an external EGR control valve (12) for controlling an amount of exhaust gas returned to the external EGR passage (11), and a valve timing varying mechanism (9A, 9B) for varying timing of opening and closing at least one of an intake valve and an exhaust valve. An ECU 100 controls the valve timing varying mechanism (9A, 9B) to always return internal EGR gas in an operation region where exhaust gas recirculation is required, and controls the external EGR control valve (12) to return exhaust gas in a combination of internal EGR and external EGR when an internal EGR rate provided by the valve timing varying mechanism (9A, 9B) is not sufficient to satisfy an EGR rate demanded depending on an operation state.
