摘要： A power unit includes an engine and a transmission mechanism, which is integrated with the engine, for transfer of power from the engine. The engine includes a crankshaft which converts a reciprocal motion of a piston to produce a rotary motion, a crankcase supporting the crankshaft, a cylinder extending from the crankcase so as to protrude in a reciprocating direction of the piston, and a cylinder head coupled to a protruding end of the cylinder. The transmission mechanism includes an output shaft arranged at one side of the crankshaft in an axial direction of the crankshaft to provide, as an output, rotational power from the crankshaft. The output shaft is positioned to a side of the crankshaft that faces the cylinder head with respect to the reciprocating direction and is positioned so as to overlap with the cylinder or the cylinder head when viewed in the axial direction.

摘要： A single-cylinder cylinder head is disclosed. The cylinder head may have a cylinder head body having a gas system side, a pushrod side opposing the gas system side, a circular cylinder closing face with a central injector opening, a pair of inlet openings, and a pair of outlet openings. The cylinder head may have a central injector recess extending through the cylinder head body to the central injector opening. Further, the cylinder head may have a gas inlet channel system and a gas outlet channel system. The cylinder head may also have a pushrod passage extending through the cylinder head body at the pushrod side. In addition, the cylinder head may have a plurality of cylinder mounting holes extending through the cylinder head body in an outer circumferential region of the single-cylinder cylinder head. The cylinder mounting holes may be non-equidistantly arranged around the central injector recess.

摘要： A marine propulsion device includes an internal combustion engine driving a driveshaft into rotation and a starter-generator motor in a torque transmitting relationship with the driveshaft. The starter-generator motor is alternately operable in a positive torque mode where it is powered by a battery to exert a positive torque on the driveshaft, and in a negative torque mode where it exerts a negative torque on the driveshaft and generates a charge to the battery. A control module is configured to receive an engine RPM, determine an engine RPM drop rate, and determine that the engine RPM drop rate exceeds a threshold drop rate. The starter-generator motor is then operated in a positive torque mode based on the engine RPM drop rate when the engine RPM drop rate exceeds the threshold drop rate.

摘要： An engine device in which exhaust pipes and an intake pipe can be mounted highly rigidly by using an upper face corner of a cylinder block in an engine, and a support structure of the exhaust pipes and the intake pipe can be simplified. In an engine device in which a first supercharger and a second supercharger are disposed in series on an exhaust gas discharge path of an engine, the engine device has a structure in which the first supercharger and the second supercharger are disposed to be divided on opposed side faces of the engine, and an upper side exhaust pipe between the engine and the first supercharger, a lower side exhaust pipe between the first supercharger and the second supercharger, and an intake pipe between the first supercharger and the second supercharger extend to be substantially flush with one another at a head-cover disposed-height of an upper face of the engine.

摘要： A spill resistant fuel supply system (16) for a marine engine (12). The system (16) includes a generally sealed housing (46) in which is disposed a vapor separator (26), a high pressure pump (28) and/or a suction pump (24). The housing (46) prevents fuel that might leak from these components from openly collecting in the marine vessel (10). The housing (46) includes one or more walls (48, 50, 52) formed with included air columns (58) which act as thermal barriers to reduce the amount of heat energy transferred from the outside in. The included air columns (58) are preferably arrayed in side-by-side fashion and closed at both ends to trap air therein.
