Embodiment Construction
[0038] Such as figure 1 Shown is the first embodiment of the present invention, which has a piston crank slider mechanism, a cylinder liner internal circulation lubrication system and a pump air booster system.
[0039] Piston crank slider mechanism is made up of piston 1, piston rod 4, slide rail 8, slide sled 9, slide block 10 and crankshaft 12. The piston 1 is integrated with the slide rail 8 through the piston rod 4 passing through the pump air chamber. Such as figure 1 , figure 2As shown, on the one hand, the upper part of the slider 10 is slidably connected with the slide rail 8 in the form of a clasp, and on the other hand, the slider is connected in rotation with the crank pin 11 of the crankshaft 12 . The piston-crank-slider mechanism formed under the above-mentioned connection state has three kinds of motion forms, that is, the piston 1, the piston rod 4, the slide rail 8, and the slide 9 do reciprocating linear motion up and down, and the slider 10 moves left an...

The invention relates to a pump-gas boosting internal combustion engine which is a reciprocating piston type four-stroke internal combustion engine, wherein through a piston crank slider mechanism, a reciprocating linear motion of a piston is turned to a rotary motion of a crankshaft under a cylinder pressure and an inertia force of the whole turning system which employs the crankshaft as a link body, and then the pump-gas boosting internal combustion engine does work outwardly; through the pump-gas boosting system, the pump-gas generated by down strokes of expansion and air suction is used for supercharging the cylinder; and a cycle lubrication system in a cylinder sleeve provides oil film lubrication for a piston ring running normally in the cylinder. The pump-gas boosting internal combustion engine ahs advantages that: 1, a fresh working medium filling amount of an air cylinder is increased more than twice and the liter power can be enhanced more than twice; 2, the vibration caused by reciprocating inertia force is greatly reduced by utilizing pump-gas pressure; 3, a linkage is canceled, and the vibration caused by second-order unbalanced inertia force is eliminated; 4, the heavy pollution of leaking gas on engine oil is eliminated, and the engine oil is only added and replenished without replacing the engine oil periodically in use, thereby obviously saving the energy and reducing the consumption; and 5, the work manner such as pressure air sweep and supplement can be used for reducing the original discharge amount of tail gas pollutants.
Description
Technical field: [0001] The pump air booster internal combustion engine of the present invention is a reciprocating piston type four-stroke internal combustion engine. Background technique: [0002] The reciprocating piston type four-stroke internal combustion engine that is widely used all over the world basically all adopts crank linkage, and adopts splash lubrication to piston and crank linkage. This structure and lubrication method have the following deficiencies: [0003] 1. The downward pumping action of the piston in the intake and expansion strokes is not utilized. [0004] 2. Under the action of side pressure, the deformation and wear of the piston in the direction of the pressure bearing surface are larger than those in other directions. In addition, the thermal expansion in each direction is different due to structural reasons, so the piston is not a simple cylinder in the axial direction. In particular, there are special requirements for the working profile of ...
