The top of cylinder 5 offers exhaust outlet 50, movable in exhaust outlet 50 to be provided with exhaust valve 9；Crank mechanism 1
Cam 10 is fixedly installed on bent axle, top and the cam 10 of exhaust valve 9 are slidably connected, and exhaust is driven by the rotation of cam 10
9 pairs of exhaust outlets 50 of door realize the operation being turned on and off.It is further fixedly arranged on fuel injector 51 and spark plug in 9 both sides of exhaust valve
52。
The bottom of cylinder 5 is further fixedly arranged on scavenging cylinder 6, and scavenging cylinder 6 can be pipe knot corresponding with 5 shape of cylinder
The internal cavities of both structure, cylinder 5 and scavenging cylinder 6 are interconnected.Piston slideway 60 is fixedly installed in scavenging cylinder 6, piston is slided
Road 60 be tubular structure, match with the inner cavity of cylinder 5 corresponding, i.e., piston 4 can along cylinder 5 inner cavity slide downward simultaneously
It slides into piston slideway 60.Scavenging channel is set between 6 upper and lower ends of piston slideway 60 and scavenging cylinder, and scavenging channel includes above sweeping
Gas channel 64 and lower scavenging channel 65.The side of scavenging cylinder 6 offers air inlet 62, be fixedly installed in air inlet 62 unidirectionally into
Air valve 63,6 bottom of scavenging cylinder offer connecting rod movable span, movable in connecting rod movable span to be equipped with connecting rod 3.
It is slidably provided with piston 4 in cylinder 5, oil duct 40 is offered in piston 4,4 periphery wall of piston offers sealing ring
Slot is detachably provided with sealing ring in closure gasket groove, and sealing ring includes first gas ring 41, oil ring 42, second gas ring 43, oil ring 42
It is set between first gas ring 41 and second gas ring 43, the closure gasket groove of oil ring 42 is connected to oil duct 40.The bottom of piston 4 and company
Bar 3 is fixedly connected, and connecting rod 3 is inverted " t " character form structure, and connecting rod 3 includes sliding sleeve 30 and link arm 31, and link arm 31 is symmetrically solid
Fixed to be arranged in 30 one end of sliding sleeve, 30 upper end of sliding sleeve is fixedly connected with the bottom of piston 4, and link arm 31 passes through outside connecting rod
2 connect with crank rotation.It is equipped with grease conduits 7 in sliding sleeve 30,70 He of oil inlet pipe is offered in grease conduits 7
Oil outlet pipe 71, oil inlet pipe 70 and oil outlet pipe 71 are connected with oil duct 40.7 one end of grease conduits is respectively arranged with oiling
Pipe 72 and oil exit pipe 73, oil fuel tube 72 are connected to oil inlet pipe 70, and oil exit pipe 73 is connected to oil outlet pipe 71, and the one of oil fuel tube 72
End is connect with oil pump 8.
When work, it is assumed that the original state of one of piston-cylinder unit is as shown in figure 5, piston 4 is located at 5 upper half of cylinder at this time
In partial work by combustion room, because cam 3 upward rotate so that exhaust valve 9 under the action of acting force of the spring or cam pulling force to
Upper movement simultaneously seals exhaust outlet 50, and then fuel injector 51 sprays into mist of oil in cylinder 5, through 52 ignition of spark plug.Mist of oil
The thrust that moment generates after burning pushes down on piston 4, when piston 4 moves down, passes through two link arms 31 on connecting rod 3
Outside connecting rod 2 is driven to move down, so that also band dynamic crankshaft realizes rotation to outside connecting rod 2.Simultaneously, since piston 4 is downward
Movement, the breather cheek valve 63 of 6 side of scavenging cylinder closes because pressure increases, and piston 4 is by 5 lower half of cylinder and scavenging pressure
Fresh air in room 61 is compressed, when piston 4 moves down and enters in the piston slideway 60 in scavenging cylinder 6, such as
Shown in Fig. 2, exhaust valve 9 is in an open state at this time, and 6 inner space of scavenging cylinder passes through upper scavenging channel 64 and 5 internal cavities of cylinder
（Work by combustion room）Connection, fresh air enter 5 internal cavities of cylinder because pressure is acted on from upper scavenging channel 64（Work by combustion
Room）In, and the exhaust gas after burning is scanned out from exhaust outlet 50, piston 4 continues to move down, and is pressed further by scavenging pressure room 61
Interior fresh air makes it enter 5 internal cavities of cylinder from lower scavenging channel 65, upper scavenging channel 64（Work by combustion room）.
During piston 4 moves down, since bent axle band moving cam 10 rotates, cam is pressed downward exhaust valve 9 so that exhaust outlet 50
With atmosphere, after piston 4 is moved to bottommost, since the turning effort of bent axle moves backward, piston 4 is moved up gas
The exhaust gas that lefts in cylinder 5 is extruded from exhaust outlet 50.Simultaneously because piston 4 moves up so that scavenging cylinder 6 becomes negative pressure state,
Breather cheek valve 63 automatically turns on, and fresh air is inhaled into the compression scavenging waited in scavenging cylinder 6 next time.When piston 4 to
On when being moved to scavenging channel 64, exhaust outlet 50 is closed, and piston 4 continues to move up the fresh air in compression cylinder 5, then
Secondary oil spout, igniting repeat the acting process.During piston 4 moves, lubricating oil is passed through oil fuel tube 72, oil inlet by oil pump 8
Pipeline 70 is pumped into oil duct 40, and since oil duct 40 is connected to closure gasket groove, the lubricating oil in oil duct 4 passes through closure gasket groove stream
Enter the inner wall of cylinder 5, lubrication is provided for piston 4.During oil pump 8 provides lubricating oil, lubricating oil absorbs piston 4 and cylinder
Heat on 5 is discharged from oil outlet pipe 71, oil exit pipe 73, to realize the effect that can be lubricated but also radiate.
The present invention in piston 4 by offering the oil duct 40 that can be connected with closure gasket groove, energy when piston is run
It is enough that lubricating oil is obtained from oil duct 40, and a part of heat is taken away by the discharge of lubricating oil, not only reduce the dimension of engine
Protect the period, moreover it is possible to considerably increase the service life of engine, therefore efficiently solve the prior art because using lubricating oil and combustion
Oily hybrid mode causes to lubricate the problem that bad, fuel consumption is big, pollution is larger.
