Description

The admission gear of rotor engine

Technical field

The present invention relates to technical field of engines, more particularly to a kind of admission gear of rotor engine.

Background technology

The engine used at present is piston-mode motor mostly, and also some engine is rotary engine.Piston Formula engine chamber and air compression process all carry out in a cylinder block, be provided in cylinder block spark plug, into, row Valve and atomizer, after atomizer sprays fluid, spark ignitor compression oil gas so that instantaneous explosion is generated in cylinder block, So as to which piston be pushed to do manual work, after acting burning, exhaust gas wants piston to push out, since cylinder block sectional area is limited, inlet valve and row Valve it is crowded in cylinder block, influence air inlet and exhaust effect etc..Present engine speed is getting faster, and torsion is changed with speed Power, more, bent axle, connecting rod, piston, piston ring, air intake valve, drain tap are worn also bigger the component of rotation so again. Under identical revolution, throw of crankshaft is longer, and the torsion of engine is bigger, however throw and connecting rod have it is certain Ratio, they mutually restrict.When piston is when doing work movement, the acting number of degrees of crank maximum are 180 degrees, and crank most preferably does work General 90 degree of the number of degrees are some more, i.e., connecting rod and crank shape are at a right angle front and rear more than 45 degree.When piston reaches top, no matter gone back in piston How many energy will drain, waste energy so by force.Some engines for other consider exhaust valve to open in advance, More energy is wasted in this way.Engine has a optimum speed, and the efficiency of engine can be all reduced above and below this speed, That is the faster efficiency of speed instead can be low.In order to improve efficiency, the ignition point of engine, in advance or postponed, carried according to rotating speed It is preceding too early or it is too late can all influence efficiency, knock appearance.And temperature is high inside existing rotary engine, wears faster, oil consumption Bigger, hardly possible repair.Applicant proposes a kind of rotor engine thus, and runner, cylinder are provided in the cylinder body of rotor engine Combustion chamber and exhaust pipe on body are set, oil spout unit and igniting unit in combustion chamber chamber are set, also set on combustion chamber Be equipped with air inlet pipe, air inlet pipe connected with combustion chamber and it is interior be passed through compressed gas, runner is integrally cylindrical, the outer wall of runner Face is provided with multiple blades, and blade is arranged in plate and length direction along the axial length direction of runner, is enclosed between adjacent blades The chamber of conjunction forms the gas chamber for pushing runner rotation, and gas chamber connects with combustion chamber, the outer rim and cylinder body of runner Form sealing cooperation.The rotatable parts of above-mentioned rotor engine are few, abrasion is few, and runner speed is faster, wherein runner Output revolving shaft radius can accomplish longer, therefore torsion bigger.However the combustion chamber of above-mentioned rotor engine is indoor As soon as often into time pressure-air, engine is done manual work once, and engine of the prior art is matched mostly using cam with valve stem The mode of conjunction realizes the open and close of valve stem, the timing belt pulley system connection of camshaft and engine, so as to fulfill starting The continuous gas entry of valve stem although above-mentioned mechanical system can realize the air inlet of valve stem, is applied and is started originally rotary-type When in machine, runner does not turn once, and valve stem turns on once, and therefore, the oil consumption of corresponding rotor engine is relatively high, Fuel economy is insufficient.
