Description
Technical field
The present invention relates to a kind of automobile engine, especially a kind of ring type engine.
Background technology
Automobile engine is since appearance before more than 100 years, and technology is constantly progressive, and existing automobile engine presses piston type
Type is roughly divided into conventional engine and rotary engine, its be by air inlet, compression, acting, exhaust four strokes,
Realize the cycle operation of engine.
Existing conventional engine mainly includes toggle, valve actuating mechanism, fuel oil supply system, igniting
System (being only used for gasoline engine), lubricating system, cooling system and starting system；Wherein, toggle includes body
Group, piston connecting rod unit and crankshaft-flywheel group, the spread pattern of the cylinder in body group include two kinds of forms：(1) in-line arrangement, that is, send out
Each cylinder of motivation forms a line, and each cylinder of (2) double-row type, i.e. engine lines up two row (including V-type motor and right
Put formula engine), toggle is the rotary motion that the straight reciprocating motion of piston is changed into bent axle, and fuel is fired
Burn the power acted on piston and be changed into the moment of torsion that bent axle externally exports, to drive automotive wheel to rotate；Valve actuating mechanism include with
Per the corresponding camshaft of exhaust casing, camshaft is driven by bent axle to rotate, and each camshaft is provided with multipair admission cam
And exhaust cam, with time opening respectively and the inlet valve and exhaust valve of each cylinder of closing；
Although constantly there are addition (such as EFI, changeable air valve, the turbocharging of new technology in conventional engine
Deng), but because of conventional engine, also there is following deficiency so that and its operating efficiency is still without revolutionary lifting：(1)
The free degree of the piston in cylinder is more, as shown in Figure 25 to Figure 26, using the reciprocating piston 100 of existing toggle
With free degree Z1, free degree Z2 and free degree Z3, it is not only slided in cylinder, can also rotate, cause piston
100 easily contact with side cylinder wall 102, and coordinate with the gap 101 of opposite side cylinder wall 102 excessive, easily cause gas leakage burning
Machine oil, produce noise, engine knock, scuffing of cylinder bore or card cylinder problem occurs；(2) when piston 100 slides in cylinder, piston 100 and cylinder
Wall 102 is high a pair friction pair, and the long-time of piston 100 does reciprocal operation along cylinder wall 102, easily causes cylinder wall 102 and lives
The abrasion of plug 100, and influence the normal work of engine；(3) piston, connecting rod and bent axle are all spatial distributions, i.e., multiple pistons
Connecting rod is not arranged in the same plane, but is arranged on a bent axle so that multiple balance weights (custom need to be set on bent axle
Claim counterweight) dynamic balancing is realized, easily cause engine vibration, consumed energy, and also create engine block and accumulate excessive, occupancy sky
Between excessive, preponderance；(4) often covering piston rod can only use for a cylinder, and each cylinder is required for an admission cam
Distribution is carried out with an exhaust cam, causes engine component excessive, volume is excessive；A large amount of lubricating oil are also required to moisten simultaneously
Sliding and cooling, add the weight of engine；(5) cylinder of conventional engine is disposed side by side on side or two mostly
Side so that cylinder is excessively concentrated and is unfavorable for radiating, and long-time high-speed cruising can cause engine water tank " boiling ", therefore its is right
Cooling system requires high, also increases the cost and weight of engine.
Existing rotary engine is made up of cocoon shape housing and the triangular rotor being placed in the housing, rotor and housing
Space between wall is rotated, the inside circumference of housing is set as internal combustion chamber by the pressure-driven rotor of gas expansion
Count into roulette profile and fitted together with the rotor on eccentric shaft, therefore, the body of rotor every revolution operating room
Product changes twice, so as to realize the four of internal combustion engine courses of work (i.e. air inlet, compression, burning and exhaust)；But because of rotor
Three drift angles are responsible for sealing, and are chronically at and can not be worked in the case of good lubrication, make easily to wear in its work, cause zero
Component life is short, and oil consumption is big, and operating efficiency is low.
