    Abstract: An upwardly protruding cylinder block (30) is formed in a front portion of a crankcase (28) for supporting a crankshaft (26) of an engine (E). A cylinder head (32) is connected with an upper portion of the cylinder block (30), and a combustion chamber (71) of an internal combustion engine is formed within the cylinder block (30) and the cylinder head (32). A knocking sensor (80) for detecting the occurrence of knocking in the engine (E) is fitted to a left side end surface (30) of the cylinder block (30).

    Abstract: An air intake chamber (74) is disposed at a location downstream of a supercharger (62) and upstream of a throttle body (76). The air intake chamber (74) serves to accumulate an intake air (I) pressurized by the supercharger (42). This air intake chamber (74) includes a confronting portion (84), which has an outlet (73) and overlaps the throttle body (76), and a connecting portion (86) that connects between the confronting portion (84) and a discharge port (48) of the supercharger (42). The connecting portion (86) has an outlet side opening (68) set to be larger than an inlet side opening (77) thereof.

    Abstract: A reference angle detecting device includes a control shaft (60) that is connected to a controlled object (e.g., to a variable valve actuation mechanism of an engine E) and an electric motor (73) that causes the control shaft (60) to rotate via a worm gear mechanism (72), a stopper (80) disposed on a motion track of a worm wheel (74), an angle sensor (94) that can detect a rotation angle of the control shaft (60), and a controller (90). The stopper (80) includes a spring member (for example, torsion coil spring (84)) which is elastically deformable in an operation direction of the worm wheel (74). The controller (90) drives the electric motor (73) to operate so that the worm wheel (74) may face the stopper (80), and stores the rotation angle at a time point when a change rate É of the rotation angle ¸ detected by the angle sensor (94) changes to a value less than a predetermined threshold É1 as a reference angle ¸ 0 . With this, the reference angle can be detected with high accuracy for control of an angle of the control shaft.
