摘要： This invention proposes a fuel injection control device for a direct injection engine which performs stable stratified charge combustion by increasing the degree of charge stratification in the air-fuel mixture through discrete double fuel injection by a fuel injection valve (12) during the compression stroke. In a predetermined operating region, the fuel injection control device for a direct injection engine divides the fuel injection pulse signal generated during compression stroke into two signals having approximately the same pulse width. The interval between the first and the second fuel injection pulse signals is determined so that a mixture cloud (32) produced by a fuel spray injected on the basis of a second fuel injection pulse signal catches up with and is superimposed on a mixture cloud (31) produced by a fuel spray injected on the basis of a first fuel injection pulse signal. The two mixture clouds are superimposed in the proximity of a spark plug (7) at the ignition timing.

摘要： In a saddle-ride type vehicle in which a cylinder head of a single-cylinder engine main unit has a front wall and a rear wall, an exhaust system being connected to the front wall and an intake system being connected to the rear wall, a joining surface of the cylinder head to a head cover is formed on a plane crossing a cylinder axis, the plane being inclined downward toward a front. Rotation axes of camshafts are arranged on the plane. An axis of a valve stem of a throttle valve is arranged on the plane. A curve cover curved so as to cover driven sprockets fixed to the camshafts is formed on one side in a vehicle width direction of the head cover. A drum housing box housing a throttle drum fixed to one end of the valve stem is arranged close to the curve cover.

摘要： When viewed from the upper face of a cylinder head (52A) in which an intake port (10A) communicating with a combustion chamber (54) of an internal combustion engine (50A) is formed, a starting point (Pl) of the port (10A) is defined as a point of intersection of the streamline of the intake port (10A) and an inlet-side opening plane of the intake port (10A) as projected on a horizontal plane (S), and an end point (P2) is defined as a point of intersection of the streamline of the port (10A) and the center -axis of an intake valve (55) as projected on the horizontal plane (S). The starting point (Pl) is located closer to the center of the chamber (54) than a straight line (L2) that contains the end point (P2) and extends in a direction orthogonal to the axis of the crankshaft on the plane (S), and the streamline (F) of the port (10A) projected on the horizontal plane (S) is curved toward the center of the chamber (54), with respect to a straight line (L1) that contains the starting point (P1) and extends in a direction orthogonal to the axis of the crankshaft on the plane (S).
