Description

Compound ic engine using multiple combustion to do work

The present invention is a kind of new-type internal combustion engine that forms that the conventional, four-stroke internal-combustion engine is reformed, the conventional, four-stroke internal-combustion engine, the about 30-40% of BTHE, the 45-55% of total heat energy is consumed by cooling water and waste gas, the main cause that its thermal efficiency is low is a unreasonable structure, for example inhale, pressure, quick-fried and arrange character and require different stroke, can only in cylinder barrel, finish successively with length, poor inspiration as a result, it is insufficient to burn, the gas that detonation produces High Temperature High Pressure is expansion working fully, and be cooled water and waste gas of remaining a large amount of heat energy consumes in vain.

At above-mentioned defect, the present invention is the two-stroke formula with traditional four-stroke internal combustion engine structural reform.For this reason, three parts such as addition vane compressor and pneumatic capstan have been formed compound ic engine using multiple combustion to do work.

This machine cycle is 360 °, is exhaust, suction, gas pressuring stroke in its preceding halftime.The later half cycle is the detonation expansion space stroke.Still have pneumatic capstan to participate in work done at (0 °-360 °) stroke in addition, then theoretical thermal efficiency exceeds about 12% than traditional four-stroke internal combustion engine, and this machine BTHE is not less than 50%, but fuel-economizing about about 30%.The body size is suitable with traditional four-journey, burning diesel oil, and gasoline, liquid gas all can.

1-3 discusses the structure and the working principle of this machine in conjunction with the accompanying drawings, and for simplicity, establishing unit A is two cylinder machines.

(1). structure is as follows:

Fig. 1 is the logic diagram of the structure and the working principle of this machine.

Fig. 2 is the structural representation of two stroke IC engine unit A and vane compressor unit B.

Fig. 3 is pneumatic capstan unit C and port timing principle schematic.

Unit A structure is based on the two stroke IC engine that reform forms on the basis of traditional four-journey two cylinder machines.

Unit A mainly contains body group 1. piston rod groups 2. bent axle backrest wheels 3. balanced controls 4. distribution device 5(and comprises camshaft timing gear, camshaft, tappet push rod, rocking arm and pitman arm shaft), valve group 6(comprises valve, valve seat, valve spring, spring seat, valve guide bushing) and composition such as cylinder appearance cooling air jacket 7.Wherein bent axle clutch 3 is connected with clutch before the unit B main shaft 12, and two exhaust valves of valve group 6 communicate with suction tude 13.

Unit B is a vane compressor, and capital equipment has: air-strainer 8, suction tude 9, gas compressor 10, compositions such as gas tank 11 and main shaft 12.Wherein air-strainer 8 and suction tude 9 all communicate with coolant jacket 7.Gas tank 11 communicates with two intake valves of valve group 6.Its main shaft and unit A bent axle 3 usefulness clutches join, and main shaft 16 tail wheels of main shaft 12 tail wheels and unit C join through chain or gear.

Unit C is a pneumatic capstan, mainly by suction tude 13, and pneumatic capstan 14, compositions such as outlet pipe 15 and main shaft 16.Wherein suction tude 13 communicates with two exhaust valves of valve group 6, and its spindle wheel 16 is connected with gas compressor tail wheel 12 by chain or gear.

(2). working principle:

Be not difficult to find out by this machine structural principle, on the basis of unit A, two-part such as addition vane compressor unit B and pneumatic capstan unit C.The working principle of unit A, this is 360 ° in new-type two-stroke piston IC engine cycle, it will finish exhaust, air inlet in (0 °-180 °) stroke, calm the anger etc. three; And in (180 °-360 °) stroke, to finish the detonation work done.In (0 °-360 °) cycle, unit B is constantly to unit A supply pressurized air, the cigarette that unit A discharges with certain capacity for work, enter remake merit among the unit C after, be discharged in the atmosphere.

The concrete condition of working principle is: bent axle backrest wheels 3 rotate, and cool air is entered in the gas compressor 10 through cooling chamber 7 and suction tude 9 by filter cleaner 8, and heating up through 10 pressurized air superchargings enters in the gas tank 11, waits to enter in the cylinder.Bent axle backrest wheels 3 rotate, and the piston in the piston set 2 is at lower dead center (0 °-P °) the waste discharge gas that moves upward, waste gas in valve group 6 exhaust valve and the suction tude 13 of unit C enter work done in the pneumatic capstan 14, decrease temperature and pressure enters in the atmosphere through smoke-ejecting pipe 15.

Unit C main shaft 16 tail wheels drag axle 12 tail wheel works done through chain or gear.When piston was raised to angle J °, the IO Intake Valve Opens in the valve group 6 had air air feed in cylinder of certain pressure in the gas tank 11, the part air directly enter in the suction tude 13 with waste gas in not clean-burning fuel carry out the burning second time.When exhaust valve reached angle P °, inlet and exhaust valve was closed simultaneously, and when (180 °-P °) of distance top dead center, the further supercharging of the fresh air in the cylinder heats up, and when arriving delivery angle G and spending, oil pump is to cylinder-in oil-jet.Once circulation is so far finished in piston work done in the stroke of angle (180 °-360 °), and the cycle is 360 °, and the phase difference of two cylinders is 180 °.

Lubricated, to supply with, start-up system all is same as traditional internal-combustion engine.

This machine fuel oil sprays in the cylinder with oil pump without exception.

Some must be described:

1. the above-mentioned cooling air jacket of cooling system, the cooling cylinder appearance also is provided with the electric fan cooling system sometimes in addition.

2. this machine is made motor car engine, can the kinetic energy of level road and descending brake or deceleration is partially recycled, raise the efficiency the saving fuel oil.

3. about effective torque of this machine, the calculating of useful horsepower is same as quartastroke engine.

Thermal efficiency X calculates respectively, and the thermal efficiency of unit A is X ₁

X ₁＝1- (P ^K-1)/(K(P-1) Y ^K-1)

Wherein Y is a compression ratio, and K is a molecular thermal capacity and the ratio of molar heat capacity under constant volume amount, and P is pre-expansibility.

The efficient of unit C: X ₂=1-1/ (Y ^(K-1)/K)

Wherein Y is a pressure ratio.

This engine efficiency: X=X ₁+ X ₂
