摘要： In an internal combustion engine having a pair of balancer shafts (53, 54), an engine torque is transmitted from a crank gear (28) to an oil pump gear (74) on a drive shaft (73) of an oil pump (71) via a first idler gear (84) and the first balancer shaft gear (64). The engine torque is also transmitted to a fuel pump (72) from the crank gear to a fuel pump gear (78) via the first idler gear and a second idler gear (86), and to the second balancer shaft gear (67) via the first idler gear and second idler gear. Alternatively, the engine torque may be transmitted to the fuel pump from the crank gear to the fuel pump gear via the first idler gear, second balancer shaft gear and second idler gear. As the oil pump gear is actuated by the crank gear via the first idler gear, the oil pump gear is not subjected to the loading caused by the balancer shaft, and hence can be made of a compact and light-weight gear. Furthermore, this allows the various gears to be arranged in an efficient (in terms of the overall weight for the given mechanical strength requirements) and compact manner.
摘要翻译：在具有一对平衡轴（53,54）的内燃机中，发动机转矩从油泵（71）的驱动轴（73）从曲轴（28）传递到油泵齿轮（74））通过第一空转齿轮（84）和第一平衡轴轴齿轮（64）。发动机转矩也经由第一空转齿轮和第二空转齿轮（86）从曲柄齿轮传递到燃料泵（72）到燃料泵齿轮（78），并经由第二空转轴齿轮（86）经由第一个空转齿轮和第二空转齿轮。或者，发动机扭矩可以经由第一空转齿轮，第二平衡器轴齿轮和第二空转齿轮从曲柄齿轮传递到燃料泵。当油泵齿轮由曲柄齿轮通过第一空转齿轮致动时，油泵齿轮不会受到由平衡轴引起的负载，因此可以由紧凑且重量轻的齿轮制成。此外，这允许各种齿轮以有效的（在给定机械强度要求的总重量方面）和紧凑的方式布置。

摘要： In a direct fuel-injection engine equipped with a pentroof-shaped piston, cross-sectional shapes containing a piston central axis (Lp) of a cavity recessed in a central part of the piston having a top face with the height varying in the circumferential direction are set so as to be basically identical at each position in the circumferential direction (see broken line). Since the sizes of the cross-sectional shapes of the cavity thereby become different in a region further on the piston central axis (Lp) side than intersection points (e1, d1) in the vicinity of a fuel injection point (Oinj), in order to compensate for this, by correcting in a cross section that is away from the piston pin direction the cross-sectional shape of the broken line into the cross-sectional shape of a solid line so that it enlarges, the size of the cross-sectional shape at each position of the circumferential direction of the cavity is thereby made more uniform, thus making the conditions in which fuel and air are mixed uniform and improving the engine output and reducing harmful exhaust materials.

摘要： A direct fuel-injection engine includes a piston, a cavity recessed in a central part of a top face of the piston, and a fuel injector. At a main injection collision point of a fuel-injection axis when main injection is performed while the piston is near top dead center, a main injection collision angle formed between its tangent and the fuel-injection axis is set at an obtuse angle. Fuel colliding with the main injection collision point is deflected towards a cavity open end side. At a secondary injection collision point of the fuel-injection axis when performing secondary injection with the piston is further from top dead center, a secondary injection collision angle formed between its tangent and the fuel-injection axis is set at one of a right angle and an acute angle. Fuel colliding with the secondary injection collision point is deflected primarily in the circumferential direction of the cavity.

摘要： A propulsion system for a watercraft includes an engine. An air intake device delivers air to a combustion chamber. A throttle valve regulates an amount of the air. A control device sets the throttle valve to a desired position. A remote controller provides the control device with the desired position. The engine can include an auxiliary intake device that delivers supplemental air to the combustion chamber. A control valve normally shuts the supplemental air from the combustion chamber. The control device determines whether an abnormal condition occurs in setting the throttle valve to the desired position. The control device determines whether the amount of the air is insufficient. The control device controls the control valve to allow the supplemental air to move to the combustion chamber when the control device determines that the abnormal condition occurs and the amount of the air is insufficient.

摘要： An internal combustion engine for an outboard motor that comprises at least one combustion chamber formed by at least a engine body, a cylinder head assembly and a piston that moves relative to the engine body and the cylinder head assembly. A crankshaft extends in a generally vertical direction and is coupled to the piston such that movement of the piston causes the crankshaft to rotate. A camshaft is journaled for rotation and extends generally parallel to the crankshaft. The camshaft includes at least one cam configured to open and close a valve. A control valve for a variable valve timing mechanism is positioned within a common hydraulic passage having a first opening and a second opening. The control valve is positioned generally along an axis that is perpendicular to the camshaft.

摘要： An engine includes an engine body that defines first and second banks arranged in a V-shape. A crankshaft extends within the engine body. First and second camshafts extend within the first bank, and third and fourth camshafts extend within the second bank. The first, second, third and fourth camshafts are generally disposed parallel to each other and parallel to the crankshaft. The first and third camshafts are placed next to each other. A first flexible transmitter surrounds the crankshaft and the first and third camshafts. The crankshaft drives the first and third camshafts through the first transmitter. A second flexible transmitter surrounds the second and fourth camshafts and either the first or third camshaft. The first or third camshaft drives the second and fourth camshafts through the second transmitter. The engine also includes VVT mechanisms to change an angular position of the camshafts relative to the crankshaft. The VVT mechanisms are disposed at the camshafts. Each VVT mechanism at least in part overlaps with either the first or second transmitter in a direction of an axis of the associated camshaft.

摘要： A marine drive has an engine, a propeller and a transmission to switch the propeller between a propulsion position and a non-propulsion position. The engine has a combustion chamber. An air induction system communicates with the combustion chamber through an intake port. An exhaust system communicates with the combustion chamber through an exhaust port. Intake and exhaust valves move between an open position and a closed position of the intake port and the exhaust port, respectively. Intake and exhaust camshafts actuate the intake and exhaust valves, respectively. A VVT mechanism changes an actuating timing of the intake camshaft at which the camshaft actuates the intake valve. An ECU controls the intake camshaft to set the actuating timing at a generally optimum timing. A transmission position change operation sensor senses that the transmission is under operation and sends a signal to the ECU. The ECU controls the VVT mechanism based upon the signal to move the actuating timing away from the optimum timing. Otherwise, a transmission position sensor senses that the transmission is in a neutral position and sends a signal to the ECU. The ECU controls the VVT mechanism based upon the signal to bring the actuating timing to a generally fully retarded timing.
