Abstract
The utility model relates to a rotary gas distribution device for an internal combustion engine, which is the novel gas distribution device used for the internal combustion engine. The utility model is characterized in that a gas distribution shaft is installed through a rotary way in a through hole of a cylinder cover which is composed of an upper half cylinder cover and a lower half cylinder cover; a gas distribution groove is processed on the gas distribution shaft according to the gas distribution phase angle of each cylinder; both sides of the groove are provided with choke rings; the gas distribution groove corresponds to a gas distribution hole on the lower half cylinder cover; a sealing hollow throat is arranged in the gas distribution hole; a rotation sealing surface is composed of the sealing hollow throat and the gas distribution shaft under the action of a spring; the gas distribution process is completed under the state of rotation; a cam which drives a monomer diesel oil high pressure pump is arranged on the gas distribution shaft so as to cause gas distribution and oil supply to be completed on the same shaft; an air inlet pipe has a double-layer structure, and the cooling medium flows in the sandwich layer. Due to the adoption of the technical scheme, the utility model can solve the problem that a plurality of deficiencies exist in the reciprocating gas distribution technology which is adopted on the existing internal combustion engine.
Description
Technical field: explosive motor rotation air distributing device is the novel distribution technology that a kind of explosive motor uses.
Background technique: come out since internal combustion engine technologies and to end till now the time in more than 100 year, the air distributing device of its explosive motor all is to adopt the reciprocating type distribution technology that is made of component such as distribution cam axle, tappet, tappet, rocking arm, rocker arm bracket, valve, valve spring.Prove through research practice for many years, when 1000 rev/mins of every raisings of the rotating speed of explosive motor, under equal oil consumption situation, its output power can increase 35-40%, power per liter weight can reduce 20-30%, though present petrol engine rotational speed is up to 5000 rev/mins, diesel engine reaches 3500 rev/mins, facts have proved if think to improve again on this basis rotating speed, had some substantive difficulties, its reason is because of present shuttle air distributing device parts the vibration knock-on that the reciprocal high-speed motion of valve causes, unbalance fractureing when valve spring resets at a high speed, the sealing surface of air valve scaling loss degenerates air-tightness.And valve when work the vibration and the noise that produce, restricted explosive motor and continued to high rotating speedization (6000 to 8000 rev/mins of petrol engine, 5000 to 7000 rev/mins of diesel engines), the process that body miniaturization and direction develops.
Summary of the invention: for solve that reciprocating type air distributing device that existing explosive motor generally adopts exists by many restriction explosive motors to high rotating speedization, the body not enough problems that develop of lightization direction in a small amount, what the utility model explosive motor rotation air distributing device designed is rotation distribution parts, there are not impact noise, sliding sealing surface during rotation, two half cylinder head up and down, installation and maintenance are convenient, long service life.On the basis of existing internal-combustion engine rotational speed, its rotating speed can improve 1000-3000 and change/more than, can increase output power 40-80%, volume weight can reduce 30-50%.Fuel oil can be saved, the manufacture cost of motor can be reduced again.
Description of drawings: Fig. 1, Fig. 2 are the utility model structural representation
Shown in Fig. 1, Fig. 2 marginal data
Explosive motor rotation air distributing device comprises rotation distribution axle (1-1), choke ring (1-2), distribution groove (1-3), coolant guiding channel (1-4), cylinder cap (2-5), sealing trunnion (2-6), air outlet flue (2-7), intake duct (2-8), double-deck air suction tude (2-9) constitute up and down.
Beneficial effect: owing to adopt technique scheme, the rotation of the utility model explosive motor is joined Device of air becomes a reality engine speed high speed, volume lightweight, namely can save Fuel oil reduces the engine production cost, reduces engine noise, can reduce in the tail gas again The discharge capacity of harmful substance Nox.
Embodiment: its feature comprises:
1, distribution cylinder cap (2-5) by up and down two form (what generally adopt at present is an integral body) half, at two stripe shape intake and exhaust of following half cylinder head bottom surface Boulez air distribution hole, (traditional is round), cylinder cap both sides Boulez exhaust ports (2-7) inlet holes (2-8) in position are provided with the mounting hole that gasoline motor spark plug and diesel engine oil nozzle are installed.
2, rotation distribution axle (1-1) is installed in the intermediate throughholes that two half cylinder cap (2-5) are formed up and down, diesel engine also can be equipped with the timing cam that drives the monomer high-pressure injection pump on rotation distribution axle, distribution, fuel feeding are finished on the same axis.
3, the corresponding stripe shape air distribution hole of cylinder cap down on the rotation distribution axle, process distribution groove (1-3) by valve timing diagram, choke ring (1-2) is installed in the both sides of groove, and rotation distribution axle is hollow shaft (1-4), and circulation can reduce the cooling medium of axis body and related components temperature.
4, be installed into outlet pipe at following half cylinder cap, sealing trunnion (2-6) forms tight rotational slide sealing surface with rotation distribution axle under the spring force effect.Be installed into tracheae (2-9) in intake duct (2-8) side, suction tude is made double layer construction, circulation cooling medium in the interlayer.Adopt this method, use on petrol engine, intake temperature can be improved the 40-80 degree, helping burning increases power output, and it also is like this using in diesel engine.If when using on being equipped with the diesel engine of exhaust-gas turbocharger, the intake temperature that the exhaust gas turbocharge effect can be heated up about 150 degree reduces the 40-80 degree.Help reducing the growing amount of Nox harmful matter in cylinder in the tail gas, Nox is that exhaust emissions reaches Europe 3, Europe
A key index of 4 standards.
5, rotation distribution axle (1-1), choke ring (1-2), sealing trunnion (2-6) parts should have grease channel, guarantee can not take place when high speed rotating the attrition surface phenomenon that degenerates.
6, the interior Boulez coolant guiding channel of upper and lower two half cylinder head (2-5), the temperature that makes its rotation distribution parts is within the 80-150 degree.
