The invention provides a buggy engine anchorage structure, which is characterized primarily by the fixing of the engine on a vehicle frame in a horizontal manner, where the output end of the engine is perpendicular to the rear wheel axle, and the output end of the engine and the rear wheel axle perpendicular to each other at first are put to carry out power linkage through a power output conversion structure by the output end of the engine, which enables the power at the output end of the engine to be transmitted through the power output conversion structure to the rear wheel axle. Accordingly, the engine fixed on the frame horizontally can no longer squeeze the space of the vehicle operator and the passengers, where the engine and the frame is then integrated into a single one piece, which substantially avoids the vibrations due to the engine as the vehicle is moving.

The auxiliary exhausting device includes an inner rotating member and an outer rotating member both having an opening communicable with an auxiliary exhausting port, two timing wheels respectively fixed to the inner and outer members with the one, which is fixed to the inner member, driven by the crankshaft, a positive driving device rotating the outer member, and a controller responsive to the operating condition of the engine for so controlling the positive driving device that the outer member is always desiredly rotated.
摘要:
A solenoid-operated injector for an electronically controlled fuel oil injection system which serves to control fuel oil injection by means of a shift of a ball valve unit. The ball valve unit includes a flat armature and a ball valve, the flat armature is shifted, floatingly, without any guidance. As the ball valve unit is sucked and moved to an open state, the flat armature abuts against a thin plate having a high magnetic resistance. The top of the flat armature is acted upon by a compressed spring with the top end of the compressed spring abutting against a spring regulating tube, so that the spring force acting on the flat armature can be changed by adjusting the spring regulating tube. Both the compressed spring and ball valve are located in the magnetic stator of the solenoid coil with the flat armature and the ball valve being located such that the spring force normally biases the ball valve against the oblique cone concave on the top of the valve seat.

Through such setup, the ATVs are capable of selecting a two-wheel drive or a four-wheel drive, subject to the demand upon various terrain conditions.
摘要:
An air-assisted fuel injection applied in the two-stroke engine of flame-jet ignition type which a fuel pump and fuel pressure regulator valve establish stable fuel rail pressure. With respect to each cylinder, a pair of fuel injection electromagnetic valve inject fuel under this pressure. The injected fuel is not directly injected into the cylinder, but is blown into main combustion chamber in the cylinder and prechamber cavity in a torch-forming plug by high speed flowing air. The ignition is performed in such a manner that the pre-mixed fuel air mixture in the prechamber cavity is first ignited by a spark discharge to form specifically shaped flame jet which is injected from one or more orifices located on lower portion of the torch-forming plug so as to successively ignite the pre-mixed fuel air mixture in the main combustion chamber. The high speed flowing air is supplied in such a manner that a small air pump and an air pressure regulating valve provide constant pressure air and with respect to each cylinder, a pair of main air injection electromagnetic valve and subsidiary air injection electromagnetic valve properly inject high speed flowing air to assist in atomizing and transferring the fuel injected from the fuel injection electromagnetic valves.
