  • Patent number: 11143068
    Abstract: An oil and gas separation device for an internal combustion engine includes a first chamber, a second chamber, and a third chamber provided successively from bottom to top, wherein the first chamber is connected to the second chamber through a first gas channel. The second chamber is connected to the third chamber through a second gas channel. The third chamber is connected to a gas outlet pipe. A bottom of the first chamber is connected to an internal combustion engine body. A lower oil baffle plate is provided between the bottom of the first chamber and the internal combustion engine body. The first gas channel is longitudinally covered by the lower oil baffle plate. The oil and gas separation effect and speed can be improved by employing the oil and gas separation device for the internal combustion engine of the present disclosure.

  • Publication number: 20210239040
    Abstract: An engine balancing system includes an engine body. At least two slider-crank mechanisms are provided inside the engine body. One of the slider-crank mechanisms is arranged opposite to the other slider-crank mechanism. A slider in one of the slider-crank mechanisms is moved at a speed and acceleration similar to a speed and acceleration of a slider in the other slider-crank mechanism. The slider-crank mechanism includes a connecting rod and a crankshaft with a crank. One end of one of the slider-crank mechanisms and one end of the other slider-crank mechanism are connected to the same crankshaft through the crank. The balancing system can effectively eliminate first-order, second-order and higher-order vibrations generated during engine operation, thus reducing the probability of equipment damage.

  • Patent number: 9273636
    Abstract: An automatic control apparatus for a carburetor choke valve includes a pull-rod, throttle control lever, choke block, and temperature control assembly which is arranged on a cylinder head through a bracket having a rotating shaft and coil spring. The rotating shaft is connected to the spring and one end of the pull-rod via a rotary arm. The other end of the pull-rod is located at a choke valve shaft. The block and valve shaft are connected to respective ends of the lever. During cold start, the block is opened driving the lever to pull the valve shaft. When rotated through a certain angle the valve shaft is blocked by part of the pull-rod, such that the valve and block cannot be fully opened. During warm start, the valve shaft when returning is blocked by another part of the pull-rod such that the valve cannot fully close.
