The present invention provides a kind of using compressed air and gasoline as the application method of the hybrid power engine of power source, and this is mixed
The mode of operation for closing power engine is as follows to pneumatic switching by fuel oil：Pneumatic hollow 180 ° of the valve rod of switching signal → rotation connects
Logical compressed air, while rotating rod makes engine rocker no-load running, makes intake valve be in normally off → switching and completes.
The mode of operation of the opposite hybrid power engine is as follows by the pneumatic process for being switched to fuel oil pattern：Fuel oil switching signal →
180 ° of closing compressed airs of hollow valve rod are rotated, while rotating rod makes engine rocker resume work state.
Compressed air and gasoline are divided into two kinds of fuel oil pattern and pneumatic mode for the hybrid power engine work of power source
Mode of operation is alternately：
（1）Fuel oil service pattern is traditional four-stroke gasoline engine mode of operation, as air-breathing（Fuel-air mixture）→ pressure
Contracting → the stroke of ignition-powering → exhaust four：When engine works under fuel oil pattern, work of the distribution sliding block in engine power
It is reciprocating under；Now the hole on hollow valve rod bar wall is closed, and compressed air can not enter cylinder；Engine fuel tail
Gas is passed through the compressed air in the shell of U-tube heat exchanger heating U-tube heat exchanger tube layer；When tube layer compressed air is heated to
When reaching upper critical temperature, pneumatic switching signal is sent by sensor；

Rotating rod, disconnects the connection of engine rocker adjusting screw and valve simultaneously, and engine charge valve starts in normally closed
Machine becomes：Compressed air air inlet acting → distribution sliding block exhaust → compressed air air inlet acting → distribution sliding block and engine exhaust
The operating pneumatic pattern of door exhaust simultaneously；When tube layer compressed air temperature is reduced to lower critical temperature, sensor sends fuel oil
Switching signal；
（3）The hole that rotating hollow 180 ° of valve rod by transmission mechanism makes on bar wall is closed, while rotating rod, makes engine
Adjusting screw of rocker arm and valve connection, engine charge valve normal work, engine recover air-breathing → compression → ignition-powering
The fuel oil service pattern of → exhaust.
The present invention realizes fuel oil and two kinds of pneumatic mode of operations on a cylinder, and absorbing engine by heat exchanger fires
About 30% energy of oily exhaust emissions, gives compressed air heating, improves the available energy of compressed air.Because compressed air exists
Expansion work is endothermic process in cylinder, and the gentle driven mixed power engine of fuel oil will not be produced in switch operating rear engine cylinder body
Raw superheating phenomenon.Because fuel oil service pattern is four-stoke mode, and operating pneumatic pattern is two-stroke mode, in identical work(
In the case of rate output, the admission pressure of operating pneumatic pattern can reduce by 2 times or so, and the operating pressure of air motor is lower,
The utilization rate of gas cylinder compressed air is higher.
The present invention can be realized by the transformation to original engine：The compressed air and the mixing that gasoline is power source
Power engine remains one compressed air air admission hole of processing on former four-stroke gasoline engine system, engine cylinder head, by closing
Engine charge valve is closed, connecting compressed air makes engine realize the mode of operation using compressed air-driven.Work as engine
When being worked under fuel oil pattern, the high-temperature tail gas that fuel oil is produced is heated by heat exchanger to compressed air.When engine is switched to
When pneumatic mode works, the compressed air of high temperature enters cylinder expansion work, while absorbing the temperature of casing wall, compressed air is realized
Efficiency highest isothermal expansion, using motor exhaust, had not only improved the heat utilization efficiency of fuel oil but also had realized compressed air
High-efficiency thermal expands, under two kinds of mode of operations, the problem of solving pure air motor insufficient driving range.
Beneficial effects of the present invention：
（1）The present invention devises a set of compressed air distribution mechanism, is realized by an air admission hole on engine cylinder head
Two functions of intake and exhaust and it is independent of each other：Engine cylinder head perforate reduces the compression ratio under engine fuel mode of operation,
But the change to compression ratio can be substantially reduced by the effect of hollow valve rod, make after cylinder head has opened hole, engine is in combustion
Still there is good dynamic property under oily condition.
（2）Compressed air and the hybrid power engine that gasoline is power source, it is four strokes to be worked under fuel oil pattern, is cut
Change that to be worked under pneumatic mode be two-stroke into, two-stroke compared to four strokes in engine displacement under the same conditions, in theory two
The power output of Stroke Engine is 2 times of four-stroke engine.When engine works under pneumatic mode, in order to realize and
Suitable power output under fuel oil four-stoke mode, the admission pressure of air motor can just be reduced, and can so be maximized
Interests gas cylinder compressed air energy.
（3）The engine is reequiped on original-pack four-stroke gasoline engine, and engine charge is realized by guide pad and slide bar
The opening and closing switching of valve, and do not changed then for the exhaust valve of engine., due to the work characteristics of air motor
Asking the intake and exhaust of air motor will complete in a short time, every four when such design makes engine be worked under pneumatic mode
Individual stroke, which is once vented, to be vented together by the air discharge duct and engine exhaust valve of distribution sliding block, is thus greatly dropped
The energy loss that low air motor is caused due to exhaust resistance.The engine is realized in a set of ripe engine system
The mode of operation of two kinds of power sources, with very strong practicality.
（4）The present invention is heated to compressed air using the waste heat from tail gas of fuel engines, changed by U-shaped pipe heat exchanger
Gaseous state change approximately meets state equation in hot device：PV=mRT, according to Charles' law, heat exchanger compressed air volume
Constant, its temperature often raises 273K, and compressed air pressure just increases 1 times.When closed 2MPa pressures in the tube layer of U-shaped pipe heat exchanger
The compressed air of power, temperature is from when being increased to 298 DEG C for 25 DEG C, and compressed air pressure increases to 4MPa..So both improve internal combustion
The fuel utilization ratio of machine, solves compressed air the problem of expansion efficiency is low in the case of adiabatic expansion again.Fuel oil and compression are empty
Gas hybrid power engine has obvious high efficiency and the effect of energy-saving and emission-reduction compared to internal combustion engine and pure air motor.
