The inlet side sloping surface is formed on one side of a pentroof apex portion as a boundary and which has an inlet port. The exhaust side sloping surface is formed on the other side of the pentroof apex portion as the boundary and which has an exhaust port. A flow improving portion is formed between the inlet port and exhaust port. The flow improving portion includes an inlet flow surface which is formed by recessing part of the inlet side sloping surface and an exhaust side guide surface. One end of the exhaust side guide surface is connected to an exhaust surface of the exhaust side sloping surface and the other end is connected to the inlet flow surface. An angle formed by the inlet flow surface and the exhaust side guide surface is smaller than or equal to an angle formed by the exhaust surface and the exhaust side guide surface.

摘要： A variable valve mechanism varies a lift amount of an inlet valve. A throttle valve is provided upstream of the inlet valve and varies an opening area of an induction passage. An automatic stopper automatically stops the internal combustion engine. A controller can put the internal combustion engine in a first induction control state in which the lift amount of the inlet valve is equal to or smaller than a predetermined amount and the opening of the throttle valve is larger than a predetermined opening with respect to a predetermined running state. The controller can put the internal combustion engine in a second induction control state in which the left amount of the inlet valve is larger than the predetermined amount and the opening of the throttle valve is equal to or smaller than the predetermined opening with respect to the predetermined running state. The automatic stopper automatically stops the internal combustion engine in a case where the lift amount of the inlet valve is equal to or smaller than the predetermined amount, when a stopping condition of the internal combustion engine is met under which a predetermined vehicle state is produced.

摘要： A variable valve device for an internal combustion engine includes a first cam phase variable mechanism capable of varying the phases of both first and second intake cams by using operating oil pressure, and a second cam phase variable mechanism having a split change function and capable of varying the phase of the second intake cam relative to that of the first intake cam by using the operating oil pressure. When the engine is operating in a low-speed, low-load region (A) in which the engine rotating speed is lower than a predetermined rotating speed (N2) and at the same time the engine load is lower than a predetermined load (L1), the second cam phase variable mechanism is preferentially controlled over the first cam phase variable mechanism.
