Thus, the valve operating system can exert both a decompression function and an exhaust gas recirculation function.

摘要： A composite control valve is constructed by a valve housing, a negative pressure working chamber defined in the valve housing to communicate with a negative pressure generating section in the engine, a first control valve operable to be opened and closed with generation and extinction of a negative pressure in the negative pressure working chamber, and a second control valve operable to be opened and closed with the generation and losing of the negative pressure in the negative pressure working chamber. The first control valve is incorporated into an air vent system which provides communication between an upper space in a fuel tank and the atmosphere, and the second control valve is incorporated into a fuel passage system which provides communication between a portion of the fuel tank below a fuel oil surface and a fuel supply section in the engine. At least a portion of the air vent system is constituted by an inner air vent pipe disposed within the fuel tank, and a gas-liquid separating device is provided in an opening of the inner air vent pipe into the upper space. Thus, upon stoppage of the operation of the engine, not only the fuel passage system but also the air vent system leading to the upper space in the fuel tank can be blocked simultaneously, to prevent release of evaporated fuel generated in the fuel tank to the atmosphere.

摘要： A variable stroke engine includes: a connecting rod connected at one end to a piston through a piston pin; a subsidiary arm turnably connected at one end to the other end of the connecting rod and connected to a crankshaft through a crankpin; and a control rod connected at one end to the subsidiary arm at a position displaced from a connection position of the connecting rod; a support position of the other end of the control rod being capable of being displaced in a plane perpendicular to an axis of the crankshaft. In the variable stroke engine, a switchover means switches over: a state in which a high expansion stroke is provided such that the stroke of the piston in an expansion stroke is larger than that in a compression stroke when an engine load is high; and a state in which a constant compression ratio is provided when the engine load is low. Thus, a reduction in fuel consumption is achieved irrespective of the level of an engine load, while putting a high value on a reduction in fuel consumption in a state in which the engine load is low.

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.
