Description
Technical field
The utility model belongs to motor, is specifically related to a kind of three stroke explosive motors.
Background technique
Practical at present internal-combustion engine technology has four stroke engine, two stroke engine and rotary engine etc. several, four stroke engine and two stroke engine all are the burnings of the fuel-air mixture body in the firing chamber by piston arrives compression stroke summit the time, drive crankshaft rotating thereby promote piston motion.One of its shortcoming is the moment of the fuel-air mixture body burning in the firing chamber, thrust maximum to the piston generation, and this moment piston rod and crankshaft crank center line and the bent axle kernel of section with being on the same straight line, what maximum thrust passed to bent axle is shearing force rather than the power that drives crankshaft rotating; Two of shortcoming is that too high or fuel label is lower than under the situation of motor fuel label requirement at compression ratio for four-stroke and two stroke engine, be easy to take place the summit that piston does not arrive compression stroke, combustion chamber temperature is with regard to the burning-point that reached the fuel-air mixture body and burn, thereby promote crankshaft reversal rotation (being engine knock), motor is caused severe impairment; Three of shortcoming is two weeks of four stroke engine crankshaft rotating just can finish four strokes, just can finish two strokes though two stroke engine whenever rotates a circle, because its gaseous emission and breathing process are insufficient, oil consumption is higher; Though it is very steadily quiet that four of shortcoming is rotary engine, yet the relative four-stroke of its actual use oil consumption is wanted height.
Summary of the invention
The utility model is for addressing the above problem the three stroke explosive motors that a kind of high power, fuel saving, low oil consumption are provided, stopped the engine knock phenomenon.
Three stroke explosive motors of the present utility model are to be made of gas cylinder, spark plug, piston, piston rod, bent axle, power crank, and the technological scheme that is adopted is that gas cylinder is provided with compression cylinder arranged side by side; Compression piston in the compression cylinder links by the compression crank on compression connecting rod and the bent axle, and the top of compression cylinder is provided with suction tude and steam outlet pipe; Top at gas cylinder and compression cylinder is provided with air reservoir, and the bottom of air reservoir is communicated with compression cylinder by steam outlet pipe, and the compression air valve of air reservoir and fuel valve are mixed into the top of gas cylinder mutually, and the top of gas cylinder also is provided with outlet pipe.
As further improvement of the utility model, the power crank on the bent axle is＞0 ° to≤90 ° with the angle that the compression crank constitutes.
Three stroke explosive motors of the present utility model, another kind of technological scheme is to be made of gas cylinder, spark plug, piston, piston rod, power crankshaft, power crank, it is characterized in that gas cylinder is provided with compression cylinder arranged side by side; Compression piston in the compression cylinder links by the compression crank on compression connecting rod and the compression crankshaft, and the termination that is fixed with driving wheel, compression crankshaft in the termination of power crankshaft is fixed with follower, and driving wheel is meshed with follower.The top of compression cylinder is provided with suction tude and steam outlet pipe; Top at gas cylinder and compression cylinder is provided with air reservoir, and the bottom of air reservoir is communicated with compression cylinder by steam outlet pipe, and the compression air valve of air reservoir and fuel valve are mixed into the top of gas cylinder mutually, and the top of gas cylinder also is provided with outlet pipe.
As further improvement of the utility model, the cylinder diameter of described compression cylinder is greater than the cylinder diameter of gas cylinder.
As further improvement of the utility model, on suction tude, steam outlet pipe, be equipped with one-way valve.
As further improvement of the utility model, the length of compression crank is greater than the length of power crank.
Three stroke explosive motors of the present utility model, each work cycle of gas cylinder are divided into gas injection, work by combustion, three working strokes of exhaust, and engine crankshaft whenever rotates a circle, and motor is finished an acting circulation, and efficient is the twice of four stroke engine; Can improve the air compression ratio to greatest extent, the right burning of fuel is more abundant, and power is more powerful; Gas cylinder and compression cylinder can be located on the same bent axle, also can be located on the different bent axles, the maximum thrust that moment that fuel burns in gas cylinder produces can all be converted into the power (moment of torsion) that drives crankshaft rotating, so the utility model is than existing, more fuel saving more powerful with displacement engine; In the piston motion process, because piston rod is vertically downward when being subjected to maximum thrust or near vertically downward, piston is zero or littler to the decomposing force of vertical cylinder body sidewall 90 degree, so piston is also just littler to the frictional force of cylinder side wall, so the wearing and tearing of engine cylinder-body are little, the life-span is longer; When pressurized gas and fuel injected gas cylinder, piston chain bar had departed from the engine knock happening part, even if in this process malcombustion takes place, the thrust of generation can only promote bent axle and rotate to predetermined direction, thoroughly stops the generation of engine knock phenomenon.Owing to stopped the engine knock phenomenon, therefore this motor is also no longer harsh to the requirement of fuel, can realize that different labels gasoline even gasoline, diesel are general, also can use other fuel such as alcohol, biogas, rock gas, liquid gas, solid particle as motor fuel, the fuel type that adapts to is more, being a kind of clean energy resource engine technology, also is a kind of new energy engine technology.
