Abstract
The invention relates to a two-stroke gear shaft engine used for cars, ships and the like. A horizontally-opposed integral type piston is adopted. The middle of the piston (11) is provided with an upper-row rack (13) and a lower-row rack (13) which are connected with a semicircular gear (15) on a power output shaft (10). Teeth are only arranged on a semicircle of the semicircular gear (15), and the other semicircle of the semicircular gear (15) is a smooth arc. The upper-row rack and the lower-row rack are alternately engaged with the gear of the power output shaft (10), so that the power output shaft (10) is pushed to continuously carry out circumferential rotation in the same direction. The defect that torque output is instable since a connecting rod and crankshaft combination mode is adopted by a traditional engine is overcome. Exhaust holes (14) are formed in the two ends of the piston (11) and connected with exhaust valves (12), and exhaust gas bypasses shell oil seals (7) through the exhaust holes (14) of the piston and is exhausted through shell exhaust holes (4). The problems that since piston oil seals (5) of a traditional two-stroke engine have to pass through the shell exhaust holes (4), engine oil is leaked and emission is not environmentally friendly are solved. The defects of emission and oil consumption are overcome fundamentally.
Description
Technical field
The present invention relates to: a kind of motor, with the power plant as automobile, steamer etc.
Background technique
At present, the motor used is always along the continuous crank-axle engine invented decades ago, although technology is ripe, old too, then without lift technique space.Complex structure, Heavy Weight, volume is large, difficulty of processing is high, crank shaft friction loss is large, and due to bent axle power arm be constantly change, it is pulsed that power, moment of torsion, speed export, and very steady, vibrations are large, and mechanical efficiency is low.As the two stroke engine be once eliminated, its power performance is better than four stroke engine.But its to life defect discharge exactly, oil consumption and lubrication be all not as good as four stroke engine, its reason is casing wall have been opened exhaust port, the mode that machine oil can only be adopted to mix so oil is lubricated, add the right oily loss in scavenging process, just to make two stroke engine can not meet the requirement of environmental protection, and scavenging loss solve already in the automatically controlled epoch.When automobile enters the oil electric mixed dynamic epoch, to the miniaturization of motor, when the requirement of high power performance is higher, some automobiles power also carries out innovative research to two stroke engine again.
Summary of the invention
In order to solve old product crank-axle engine complex structure, Heavy Weight, volume is large, loss is large, efficiency is low, and power is defeated not steady, and traditional two stroke engine machine oil mixing so oil defect not environmentally.Be modified into two stroke engine further, adopt horizontally-opposed one-piece piston, in the mode of tooth bar and half-turn Gear combination, reach and convert the back and forth movement of piston to pto＝power take-off continuously towards the circular movement in a direction, solving conventional engines adopts the moment of torsion of connecting rod and bent axle compound mode to export jiggly defect, reaches steady Power output.Creationary employing piston begins to rehearse the mode of valve, and after exhaust port is changed into piston oil seal, such piston does not just need through exhaust port in movement process.Just do not need the mode adopting machine oil mixing so oily, the lubricating system that four-stroke is same can be adopted, fundamentally solve discharge yet, and the defect of oil consumption.And eliminate bent axle, camshaft, timing chain etc. simultaneously.Greatly simplify structure, by volume microminiaturization.Integrate rotary engine, advantage that two stroke engine, four-stroke are started, and overcome three kinds of respective defects of starting.
Technical side's peace of the present invention is: adopt one-piece piston, run in horizontally-opposed mode, pto＝power take-off (10) is provided with half-turn gear (15), two rows piston-rack (13) is opened by the middle of piston (11), piston (11) two ends have piston exhaust ports (14), and piston-rack (13) connects half-turn gear (15).Half-turn gear (15) half-turn has tooth, and another half-turn is smooth circular arc.When piston runs to a left side (right side) stop, upper (lower) piston-rack (13) has the half-turn of tooth to start to be engaged with half-turn gear (15), under (on) point of contact of piston-rack (13) and half-turn gear (15) just in time starts to depart from anodontia half-turn place, once, propulsion power output shaft (10) rotates 180 degree along (inverse) hour hands in piston (11) acting.When piston runs to the right side (left side) stop, under (on) piston-rack (13) has the half-turn of tooth to start to be engaged with half-turn gear (15), upper (lower) piston-rack (13) just in time starts to depart from anodontia half-turn place with the point of contact of half-turn gear (15), piston-rack (13) and half-turn gear (15) are alternately engaged disengaging and complete a power cycle, propulsion power output shaft (10) rotates 360 degree, reaches and converts the back and forth movement of piston (11) to pto＝power take-off (10) continuously towards the circular movement in a direction.Solving conventional engines adopts the moment of torsion of connecting rod and bent axle compound mode to export jiggly defect, reaches steady Power output.
Piston exhaust ports (14) is opened at piston (11) two ends, piston (11) two ends are provided with exhaust valve (12), when piston (11) runs to a left side (right side) stop soon, right (left side) exhaust valve (12) is rushed open by exhaust valve block (9) automatically, automatically close under the action of the spring when leaving, when right (left side) exhaust valve (12) is beaten, piston exhaust ports (14) is communicated with enclosure exhaust hole (4), and waste gas is walked around shell oil sealing (7) through piston exhaust ports (14) and discharged by enclosure exhaust hole (4).Be different from conventional engines oil sealing is connected on piston, but shell oil sealing (7) is connected on shell (8).Play effect machine oil and exhaust port isolated.Solve traditional two stroke engine piston oil seal to have to pass through enclosure exhaust hole and can leak machine oil, machine oil can only be taked to mix the combustion manner discharge defect not environmentally of so oil, the lubricating system that four-stroke is same can be adopted, fundamentally solve discharge, and the defect of oil consumption.
At shell (8) upper connection air inlet nozzle (2), adopt in-cylinder direct injection to enter the mode of air continuously, make the abundant stratified mixture combustion of blended fuel oil.Cancel the intake valve of conventional engines.Both ensure that sufficient air inflow, and can clear away while exhaust gas inside cylinder saves fuel oil again again reducing cylinder temperature with air, reach the effect of achieving many things at one stroke.
The invention has the beneficial effects as follows: cancel bent axle, the camshaft of conventional engines, timing chain etc., reduce weight and volume greatly, allow more compact structure.Enhance reliability, workability, reduce production and maintenance cost.Simple and reliable for structure, shake little noise little.Be: gear transmission arm is equal that it is linear type that power, moment of torsion, speed export by it, suitable with rotary engine, very steadily, mechanical efficiency is high.
