摘要： In a vertical engine, a bulged portion protrudes upwards, in conformity to a partially cylindrical outer wall of uppermost one of cylinders, on an upper surface of a cylinder block forming a bottom wall of a chain chamber accommodating a chain for driving a camshaft and a balancer shaft through a crankshaft. A pair of oil return bores for returning an oil in the chain chamber to an oil pan are provided in lower portions of the bottom wall on opposite sides of an axis of the bulged portion. The oil which has lubricated the chain in the chain chamber flows so that it is distributed to the opposite sides of the axis, and the oil is returned smoothly from the oil return bores formed in the bottom wall to the oil pan.

摘要： Recesses are provided in portions of a head cover and a crankcase which are opposed to outer peripheries of a timing chain and a balancer-driving chain driven by a crankshaft of a vertical engine, whereby vertical walls and horizontal walls are formed to oppose to outer peripheral surfaces and lower surfaces of the timing chain and the balancer-driving chain. An oil scattered from the timing chain and the balancer-driving chain by a centrifugal force is caught on the vertical walls, and the oil flowing down along the vertical walls by gravitation is retained on the underlying horizontal walls, whereby the oil can be brought into contact with the chains without waste to effectively lubricate the chains.

摘要： A first chain mechanism for transmitting the rotation of a crankshaft of an vertical engine to a camshaft and a second chain mechanism for transmitting the rotation of the crankshaft to a balancer shaft are forcibly lubricated by an oil injected by first, second and third oil jets mounted within a chain chamber. The first, second and third oil jets are disposed at locations closer to the crankshaft, the cam shaft and the balancer shaft, respectively, and the first and second oil jets are disposed inside a travel locus for a timing chain. Thus, the chain mechanisms disposed in a plane of the vertical engine can be lubricated effectively.

摘要： A base member mounted to a side of a cylinder block is formed with an inlet-side oil supply passage for supplying an oil to an oil filter, and an outlet-side oil supply passage for discharging the oil from the oil filter. As a result, it is unnecessary to increase the thickness of a wall of the cylinder block or to form a bulged portion in order to form the oil supply passages, thereby contributing to a decrease in weight of the cylinder block. Moreover, because the oil supply passages are formed in the base member, the layouts thereof can be determined freely without restrained by the shape of the cylinder block, thereby contributing an increase in degree of freedom for the design.

摘要： In a water-cooled multi-cylinder vertical engine for an outboard engine system, cooling water having passed through an exhaust-manifold cooling water jacket for cooling an exhaust passage within an engine room is supplied to a cylinder-block cooling water jacket provided in a cylinder block through water supply pipes, a branching member and two upper and lower couplings. In this case, the lower coupling is locked below the center of a lowermost cylinder to minimize unevenness in flow rate of the cooling water flowing through a water jacket on opposite left and right sides of a cylinder toward a cooling water outlet provided at an upper portion thereof, thereby making uniform the distribution of the temperature around a combustion chamber, leading to an enhancement in cooling effect.

摘要： In an outboard engine system, a first opening communicating with a cooling water discharge passage and a second opening communicating with a cooling water supply passage are formed adjacent to each other in an upper wall of a cooling water passage forming member. A relief valve is provided in a first opening at a position remote from a tilt shaft. The relief valve includes a valve seat provided at the upper wall and facing downward. A valve body is seated on the valve seat from below. Accordingly, any cooling water staying in an upper portion of the relief valve leaks through gaps between the valve seat and the valve body to be discharged easily. When the outboard engine system is tilted upward about the tilt shaft, the opening provided with the relief valve is moved upward so that the cooling water is discharged smoothly through the other opening.
摘要翻译：在舷外发动机系统中，与冷却水排出通道连通的第一开口和与冷却水供给通道连通的第二开口在冷却水通道形成构件的上壁中彼此相邻地形成。安全阀设置在远离倾斜轴的位置处的第一开口中。安全阀包括设置在上壁处并面向下的阀座。阀体从下方就座在阀座上。因此，停留在安全阀的上部的任何冷却水通过阀座与阀体之间的间隙而泄漏，容易排出。当外侧发动机系统围绕倾斜轴向上倾斜时，设置有安全阀的开口向上移动，使得冷却水通过另一个开口平稳地排出。
