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.

The present invention relates to a fuel injection system driven by compressor. 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. The ignition is performed in such a manner that the pre-mixed fuel air mixture in the pre-combustion chamber is first ignited by the spark plug and is injected from a lower passage of the torch-forming plug in a flame pattern with specific shape to successively ignite pre-mixed fuel air mixture in main combustion chamber.

A wheel arrangement for a four-wheeled vehicle is comprised of a front wheel, two side wheels and a rear wheel, whereas the rear wheel is connected to the frame of the vehicle by a supporting base enabling the same to be steered freely while having a ground-touching point of the same to be biased from the axis of the supporting base by a distance, and the front wheel can be specified as a driving wheel, a free-rolling steering wheel or just a steering wheel with respect to actual requirement, and the two side wheels can be specified as a driving wheels or free-rolling wheels while enabling the axis of the two side wheels to be aligned to a straight line without sharing a same shaft. The wheel arrangement can be a rhombus configuration as the distances between the center of the front wheel and the centers of the two side wheels are the same as that of the center of the rear wheel and the centers of the two side wheels, or can be a diamond configuration as the distances between the center of the front wheel and the centers of the two side wheels are different from that of the center of the rear wheel and the centers of the two side wheels.
摘要:
A controlled odor generator, comprising a central processing unit, at least one micropump unit, a sensor unit and a fan. The micropump unit is housed in a casing containing odorous fluid and has a micropump array for ejecting the odorous fluid in tiny droplets. The central processing unit regulates operation of the micropump unit, allowing to control timing quantity and mixture of spread odor. The sensor unit provides the central processing unit with environmental data, like temperature, air density and humidity, as well as human body states for controlling the micropump unit. Environmental changes are followed by a change of spraying of odor, and varying taste and demand are adapted to.

The linkage mechanism comprises: a connecting part and a four-bar linkage structure composed of a ground rod, a floating rod, placed over the ground rod and parallel thereto, and two rocking arms; wherein an end of the floating rod is pivotally connected to an end of one rocking arm while another end of the floating rod is pivotally connected to an end of another rocking arm; and an end of the ground rod is pivotally connected to an end of one rocking arms opposite to that connected to the floating rod while another end of the ground rod is pivotally connected to an end of another rocking arm opposite to that connected to the floating rod; and the connecting part has a bulging sliding block matched and inset into a straight sliding slot arranged near center of the floating rod while the bottom of the connecting part is pivotally connected to a specific position of the ground rod near the center thereof. The suspending mechanism comprises: a hub, two suspending rods and a shock absorber; wherein the hub is pivotally connected to the rocking arm by the two suspending rods, and the top of the shock absorber is pivotally connected to the top of one rocking arm while the bottom of the shock absorber is pivotally connected to the bottom of the hub.
摘要:
A decompression device for a four-stroke engine, which drives the inlet valve and the exhaust valve by using the profile surface of a cam and rocker mechanism. This cam includes a guiding recess provided on the side surface thereof and a slot provided on the cam profile surface communicating with the guiding recess. The decompression device further includes a centrifugal member, received within the guiding recess, having a projecting portion and being rotatable and movable within the guiding recess, and a spring having two ends fixed to the cam and the centrifugal member. By the cooperation with the spring and the guiding recess, when the cam is rotated at a lower speed, the projecting portion of the centrifugal member projects through the slot to the outside of the cam profile surface under the action of a weaker centrifugal force, thereby lifting the second follower so as to open the exhaust valve before the TDC of the compression stroke, and when the cam is rotated at a higher speed, the projecting portion of the centrifugal member sinks into the inside of the cam profile surface under the action of a stronger centrifugal force, thereby closing the exhaust valve.

An improved lubricating device for a four-stroke engine which permits the engine to operate upside down for a longer time and which has a better lubricating effect. This device comprises a first partitioning portion dividing the lubricating oil reservoir into a first and a second chambers, and a second partitioning portion further dividing the second chamber into a first and a second sub-chambers. The first partitioning portion includes a concave portion, having an opening for communicating the first chamber with the second chamber, which is adapted to receive some lubricating oil. Also, the first partitioning portion is provided thereon with a check valve which allows irreversible flow of the lubricating oil mist between the first chamber and the second sub-chamber. Moreover, this invention provides a complete circulation path for lubricating oil wherein the lubricating oil is transferred from the first chamber to the rocker chamber, then enters the main shaft chamber and finally returns back to the first chamber, thereby fully lubricating all the parts in the engine and greatly improving the lubricating effect.
