摘要： A single air intake port 32 is connected to a principal surface 29 of a combustion chamber defining portion 105 of a cylinder head 22. A first end 372a of a valve shaft 372 of an air intake valve 37 is connected to a valve head. An injection nozzle 47b of an injector 47 injects the fuel in the form of mist toward the combustion chamber B4 through the air intake port 32. At least while idling, assist air is led to a space near the injection nozzle 47b. As viewed in the cylinder axis direction, the first end 372a of the valve shaft 372 is arranged between the center axis A4 of the injection nozzle 47b and an igniter 115 of an ignition plug 104. This improves fuel combustion efficiency by promoting atomization of fuel.

摘要： An injector 11 is disposed at such an angle that an injection nozzle 11a is arranged opposite to intake valve openings 3e and a mixture of a fuel injected from the injection nozzle 11a and air generates air motion in a cylinder. The air-fuel mixture is directly injected from the intake valve openings 3e which are opened during fuel injection of the injector 11 into a cylinder bore 2b to generate the air motion. As a result, it is possible to reduce the amount of fuel adhering to wall surfaces without causing worsening of combustion characteristics and improve exhaust gas conditions and throttle responsivity.

摘要： An internal combustion engine has throttle valves (22) installed, each of its air intake passages (21) connecting a surge tank (20) with each of the cylinders (3). An inter-cylindrical connecting passage (29) is formed near the air intake valves between adjacent air intake passages (21). An auxiliary air intake passage (26,28) branches from the surge tank (20) to bypass the throttle valve (22) and connects to the inter-cylindrical connecting passage (29). An idle speed control valve (27) is installed in the auxiliary air intake passage (26,28). Thus, stabilized combustion of the air/fuel mixture even during the low to mid-load operating ranges can be obtained to improve fuel economy and reduce NO X emissions. The invention is of particular advantage in engines using exhaust gas recirculation.
