Working principle of the present utility model: after using a kind of novel piston push and pull system of the utility model, piston will be not in motion again the countercylinder body produce horizontal extruding force, because because the horizontal extruding force that master connecting rod produces can be born by guide rail, share to each bearing of both sides, just can avoid between piston and the cylinder block like this producing serious wearing and tearing, thereby improve greatly the working life of piston and cylinder block.
A kind of novel piston push and pull system, its beneficial effect is:
1. the anti-shelves that drag: when motor is worked under the situation of dragging shelves, wearing and tearing between cylinder block and the piston are very serious, adopted the novel piston push and pull system of guide rail technology when use after, though slave connecting rod can be movable but be kept motionless, when master connecting rod moves like this, just can not produce horizontal extruding force again between piston and the cylinder block.
2. prolongation engine life: because after having used the guide rail technology, cylinder block and wearing for piston have been reduced greatly, so also just natural working life that can prolong motor, the wearing and tearing sheet that can change is being installed between vertical plane and the bearing or between vertical plane and the bearing and between cylinder block and the bearing, be replaceable new wearing and tearing sheet after may wear to a certain degree, thereby reduce maintenance expenses.
3. stable performance: because cylinder block and wearing for piston have reduced, the excellent sealing between cylinder and the piston just can keep for a long time, and the output power of motor just can not descend, and the oil consumption of motor just can not increase yet.
Core of the present utility model is exactly to utilize novel mechanical that piston action is transferred to other component on the motor in the extruding force of cylinder inner wall, perhaps casing outer wall, and the utility model goes for all fuel engines.
