A prime mover for a lightweight vehicle comprising an internal combustion engine, a starter motor integrally integrated with the internal combustion engine, and a housing for the prime mover. The prime mover additionally comprises a Hall Effect sensor and an prime mover control module structured and operable to communicate with the Hall Effect sensor, determine when operation of the internal combustion engine should cease, and upon the determination that operation of the internal combustion engine should cease, utilize the communication from the Hall Effect sensor to stop the internal combustion engine such that a piston of the internal combustion engine is positioned at between 15° and 25° after bottom-dead-center.

A permanently engaged starter system for use in a vehicle includes a flex plate. The vehicle includes a crankshaft and an engine block. The flex plate extends along and is rotatable about an axis. The flex plate is adapted to be rotatably coupled to the crankshaft. The permanently engaged starter system also includes a one-way clutch including an outer and inner race. The permanently engaged starter system additionally includes a ring gear rotatably coupled to one of the inner race and the outer race of the one-way clutch. The permanently engaged starter system further includes a starter support plate, and a pilot support plate coupled to the ring gear. The pilot support plate is fixedly coupled to the starter support plate and is configured to axially and radially align and retain the ring gear and one of the inner race and the outer race with respect to the axis.

There is provided a rope reel provided in a recoil starter including: a rope holding groove; a flange portion disposed on both sides of the rope holding groove; a through hole provided in the flange portion and configured to allow an end of the rope wound around the rope holding groove to pass through; and an arch portion provided on a side surface of the rope reel and adjacent to the through hole. The arch portion is configured such that the rope is inserted therein, and the arch portion is capable of holding the inserted rope along the side surface of the rope reel. According to the above configuration, a front end portion of the rope is prevented from interfering with a rotation member at an engine side.

An engine-and-electric-machine assembly is provided that includes an engine and an electric machine, a crankshaft being provided in the engine, the crankshaft including a main body and an extension section that extends out to the exterior of the engine, the extension section forming a rotation shaft of the electric machine, and a rotor of the electric machine being mounted on the extension section. Moreover, a terminal of the rotation shaft is connected to a coolant pump, a rotor of the coolant pump is mounted to the rotation shaft, and while the rotation shaft is rotating the rotation shaft drives the coolant pump to provide coolant to the electric machine. By connecting the rotation shaft of the electric machine to the coolant pump, the assembly enables the pump to be highly integrated into the system and reduce manufacturing cost.

An engine exhaust manifold including exhaust inlet parts at four locations corresponding to a plurality of exhaust ports, one exhaust outlet part, and an exhaust confluence part to collect exhaust gas from each of the exhaust inlet parts and send to the exhaust outlet part. An EGR passage part to send EGR gas toward an intake passage is formed.

An internal combustion engine is described, including at least one starter (1) having a starter transmission that is situated at the opposite end of the crankshaft or at the same end to transfer the rotation of the starter (1) to the crankshaft, the starter (1) being situated at the crankcase (4) of the internal combustion engine and the starter (1) being inserted into a receiving hole (7) and being situated in a fastenable manner at the crankcase (4) with the aid of at least one screw (2), and a holder (5) being situated at the starter (1).

A compressed self-ignition type internal combustion engine includes a fuel injection nozzle provided such that a plurality of injection holes are exposed from a cylinder head of the internal combustion engine to a combustion chamber, and a plurality of hollow ducts configured such that an inlet and an outlet are exposed to the combustion chamber. The plurality of ducts are configured such that each fuel spray injected from the plurality of injection holes of the fuel injection nozzle passes from the inlet to the outlet. The internal combustion engine includes a heating device for heating at least one of the plurality of ducts.

An engine assembly is provided that includes an engine having a crankshaft that is caused to rotate response to a firing of the engine, a backplate affixed to the engine and comprising one or more air flow passages formed therethrough, and an engine cooling fan operatively coupled to the crankshaft so as to be rotated by the crankshaft, the engine cooling fan coupled to the crankshaft on a side of the backplate opposite the engine. The engine assembly also includes a fan cover mounted over the engine cooling fan and secured to the backplate, the fan cover including an opening through which an air flow is provided to the engine cooling. The backplate and the fan cover collectively form an air guide that directs a flow of cooling air generated by the engine cooling fan through the one or more air flow passages of the backplate and to the engine.
