摘要： A liquid cooled internal combustion engine, comprising: an integrally cast engine main body including a cylinder block, a cylinder head, and a crankcase skirt, a crankcase cover attached to an open end of the skirt to define a crankcase therein, a crankshaft extending vertically in the crankcase and rotatably supported by the skirt at its both ends, a camshaft rotatably supported by the cylinder head and extending in parallel with the crankshaft, a timing belt passed around pulleys mounted on lower ends of the camshaft and the crankshaft, respectively, and extending in a belt chamber defined in the cylinder block along a lower side of the cylinder bore; a cooling liquid jacket defined in the cylinder block along upper and lateral sides of the cylinder bore. The jacket may be formed during the casting process by pulling a core either upwards or toward the open end of the skirt. The cooling liquid may consist of the lubricating oil for the engine. Thus, a jacket for the cooling liquid can be formed without requiring its cylinder head to be cast separately from its cylinder block, and the rigidity of the part of the cylinder block adjoining its cylinder head can be increased without increasing its wall thickness. Also, a compact design of the engine is made possible, and the process of fabricating the engine can be simplified.

摘要： An OHC vertical crankshaft engine, comprising: a vertically disposed crankshaft having a first timing pulley at its lower end; a cooling fan attached to an upper end of the crankshaft; a camshaft extending in parallel with the crankshaft at a cylinder head end of the engine and having a second timing pulley at its lower end; and a timing belt passed around the timing pulleys. Thus, the need for lubrication for the transmission mechanism between the crankshaft and the camshaft is substantially eliminated, and the noise generation is reduced. Additionally, since the upper part of the cylinder head is directly exposed to the cooling air produced by a fan provided at an upper end of the crankshaft, a high engine cooling efficiency can be achieved. This effect is even more enhanced if the exhaust port of the engine is disposed above the intake port and extends horizontally and linearly away from the engine.

摘要： An overhead camshaft V-2 engine includes a single power transmitting mechanism disposed on one side of a crankcase for transmitting rotational power from a crankshaft to respective camshafts of drive valve mechanisms. The power transmitting mechanism has a driving member mounted to only one end portion of the crankshaft. The thus arranged power transmitting mechanism enables downsizing of the engine. Two intake ports are formed in respective cylinder heads of two cylinder blocks and open at one end to respective first surfaces of the cylinder heads facing in a first direction, and two exhaust ports are formed in the respective cylinder heads of the cylinder blocks and open at one end to respective second surfaces of the cylinder heads facing in a second direction opposite to the first direction. With this arrangement of the intake and exhaust ports, intake pipes can be arranged with a high degree of freedom.

摘要： A V-2 engine includes two cylinder blocks mounted to a crankcase such that the respective cylinder axes of the cylinder blocks extend at an angle to each other and merge together at the axis of a crankshaft with the angle formed between the cylinder axes being divided into two angle parts by a centerline of the crankcase passing through the axis of the crankshaft, and an auxiliary machine mounted to the crankcase on the same side as one of the cylinder blocks when viewed from the axis of the crankshaft. In order to reduce the maximum width of the engine, the cylinder blocks are offset from a symmetric position with respect to the centerline of the crankcase to such an extent that a straight line circumscribing an outer end of a head cover attached to the one cylinder block and an outer end of the auxiliary machine is in parallel to the centerline of the crankcase.

摘要： An oil level detection apparatus having a float-type oil level detector (50) and a mode switching unit. The oil level detector emits a signal indicating that the oil level has dropped when a movable contact disposed on a float (54) makes contact with fixed contacts once the level of said oil (Lu) has dropped to a lower limit level. The mode switching unit switches between one of two modes selected from a first mode for actuating the alarm and stopping the engine (10) in accordance with the level drop signal, and a second mode for actuating the alarm and continuing to operate the engine (10) in accordance with the level drop signal.

摘要： A variable compression ratio engine includes a support shaft positioned eccentrically relative to rotating shafts. A restricting projection is provided at one location in the circumferential direction on the rotating shafts so as to project outward in the radial direction. A rocker member has a pair of engagement portions with respective phases displaced from each other and which engage the restricting projection. The rocker member is spring-biased in a direction in which one of the two engagement portions engages the restricting projection and is mounted on a shaft member so as to be able to rock around the axis of the shaft member. An actuator is driven by the engine negative pressure and is connected to the rocker member so as to swing the rocker member in a direction opposite to the spring-bias direction.
