The concrete technical scheme that the present invention adopts is: on the basis of original internal combustion engine, increase 1-4 assisted gasCylinder, with original system common crankshaft, camshaft, lubricating system, cooling system, timing system, straight engineCan increase 1-2 cylinder, V puts or the opposed 2-4 of an increasing cylinder, to the 1-4 a newly increasing assisted gasCylinder one section of camshaft used is transformed, and each inlet and outlet cam valve projection is by changing symmetry a Monday intoTwo projections, make air inlet and exhaust by camshaft circle open and close once change into open and close twice, assistant cylinderCorresponding valve, adopts the two-stage combined type valve with two way seal ability of innovative design or magnetic force two slidingDynamic formula valve, while preventing inlet and outlet place high pressure, high-pressure jack drives valve into, increases an additional-air inlet air filterClear device or shared with former air filter, increases a compressed air reservoir, comprises corresponding tonifying Qi on air accumulatorValve, safety valve, draining valve, several assistant cylinders share air intake duct and exhaust duct, at assistant cylinder air intake ductAir inlet electromagnetic valve of front increase, respectively with additional-air inlet air filter, compressed air reservoir, auxiliaryInlet cylinder is connected, and selects to switch by magnetic valve, and air intake duct can communicate with additional-air inlet air filter,Also can communicate with compressed air reservoir, or increase between auxiliary air filter and assistant cylinder air intake ductOne can only be to the breather check valve of inlet valve direction air inlet, assistant cylinder air intake duct respectively by magnetic valve andBreather check valve is connected with auxiliary air filter with compressed air reservoir, increases at assistant cylinder exhaust duct placeAdd an exhaust solenoid valve, be connected with gas circuit, gas storage check valve before assistant cylinder exhaust duct, air throttle respectively,Gas storage check valve is connected with compressed air reservoir, and assistant cylinder exhaust duct is by the switching of exhaust solenoid valve,Can with engine throttle in front of the door gas circuit communicate, or communicate with compressed air reservoir by gas storage check valve, storageGas check valve can prevent air accumulator pressure-air backflow vent road, and assistant cylinder exhaust duct also can pass through magnetic valveDirectly be connected with gas circuit before air throttle, and compressed air reservoir can be arranged with assistant cylinder by gas storage check valveAir flue is connected, and increases a main breather check valve after engine air filter, and air filter is by mainBreather check valve is connected with air throttle again, prevents the high pressure sky of coming from assistant cylinder exhaust valve before air throttleGas, runs away from air filter, and main breather check valve can and connect a safety valve, prevents the front air pressure of air throttleWhen too high, damage gas circuit, each assistant cylinder also can be direct by breather check valve and air filter separatelyBe connected, be directly connected with compressed air reservoir by gas storage check valve separately. Assistant cylinder adopts two-stageWhen combined bidirectional sealed air valve structure, inlet valve is the common valve composition of two-stage, and two valve seatings pass through gasRoad communicates, and it is that valve below communicates with cylinder that one of them valve is opened direction, and another valve is opened directionCommunicate with assistant cylinder air inlet, two valve synchronous or successively opening and closing by camshaft control, or protrudingWheel shaft is only controlled air inlet end valve, and using with cylinder phase go side valve can only be to the check valve generation of air inlet in cylinderReplace, under the acting in conjunction of two-stage valve, all can not push open from the high pressure in high pressure and the cylinder of air accumulatorValve, reaches bidirectional high-pressure sealing function. Exhaust valve is also the two way seal air valve structure that two valves form,Two valve seatings communicate by air flue, and air flue should be short as far as possible, and one of them valve is opened direction and cylinder phaseLogical, another valve is opened direction and is communicated with assistant cylinder exhaust outlet, and two valves by camshaft control simultaneouslyOr successively opening and closing, or camshaft control and cylinder phase go side valve, exhaust port side valve use can only be toThe check valve of outer exhaust replaces. Two-stage combined bidirectional sealed air valve structure, employing be on internal combustion engineThe valve generally using, its processability, reliability are all very high, have realized bidirectional high-pressure by cam simultaneouslyAxle, the reliable requirement of controlling of valve, solved the difficult problem of camshaft air inlet door to high voltage control, andLargely solve the impact that blast pipe inner high voltage air flows backwards on air inlet, only between two-stage valve in air flueThere is part pressure-air to have very little impact, should reduce as far as possible distance and volume between two-stage valve, to fallLow impact. The present invention also can adopt the two slidingtype two way seal air valve structures of magnetic force, at assistant cylinder air intake ductAnd a next door is set between cylinder, and next door is parallel with the valve stem direction of motion, and make with high-abrasive material in next doorOr two sides inlays high-abrasive material, on next door, open pore, be communicated with air intake duct and cylinder, passage is narrow up and down,Left and right is wide, meets valve stroke short, the requirement that free space is little, two slide block shapes and the basic phase of passageWith, area is slightly larger than passage, and two slide blocks can attract each other under magnetic material effect, at magnetic materialUnder effect, be relatively attached to both sides, next door, and the passage on next door can be blocked completely, make valve stem bottomThe square-box shape of side opening is enclosed within on slide block, and available spring leaf is clamped slide block, stretches but do not affect slide block phase the other side casketContracting, slide block can slide up and down along next door under the drive of valve stem, and passage is opened or closed, two cunningsPiece can use single valve stem to drive one, and another is by magnetic servo, or the each drive one of employing dual valve barIndividual, exhaust side can adopt air valve structure identical with air inlet side to be communicated with cylinder and exhaust duct. The two slidingtypes of magnetic force are twoTo sealed air valve structure, overcome two-stage combined bidirectional sealed air valve, between two-stage valve, in air flue, also haveThe little defect of part pressure-air, but that reliability has is to be tested. Assistant cylinder should reduce can press in cylinder as far as possibleContracting space, meets pneumatic and compressed-air actuated requirement, has increased two way seal valve installing space simultaneously.
