Abstract: 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 are perpendicular to each other to carry out a 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 no longer squeezes the space of the vehicle operator and the passengers. Additionally, the engine and the frame can be then integrated into a single piece, which substantially avoids the vibrations due to the engine as the vehicle is moving.

Abstract: A large torque diverting device for an engine transmission system includes a cylinder between a bowl-shaped disc and a drive shaft. The cylinder rotates the drive shaft, which then rotated the rear wheels. The cylinder has plural insert grooves and the bowl-shaped also has plural ball holes to correspond to one another for steel balls to fit therein. When the drive shaft and the rear wheels receive a too large load or shock, and if the cylinder and drive shaft becomes deadlocked immovable, with the bowl-shaped disc still rotating, the bowl-shaped disc pushes a push ring to compress an elastic member to force instantly the steel balls separate from the cylinder to instantly release the large torque so as to protect the transmission gears and the shell from damaged, cracked or broken.

Abstract: 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 system is used in two-stroke gasoline engine, wherein high speed air flow is applied to assist in fuel atomization and injection. The system works in such a manner that a fuel pump and fuel pressure regulating valve establish stable fuel injection pressure and fuel is injected under this stable pressure by a main fuel injector and a sub-fuel injector. The fuel is not directly injected into the cylinder, but blown into main combustion chamber of the cylinder and pre-combustion chamber of a torch-forming plug by little amount of high speed air flow supplied from a small compressor synchroinzed with the engine in operation, the high speed air flow being distributed by a distributor to flow into air passages of the main fuel injector and sub-fuel injector for blowing the injected fuel.

Abstract: 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.
