Abstract
The present invention relates to an IC engine rotating distribution device. It can be substituted for traditional IC engine reciprocating distribution device formed from the components of cam shaft, capper, rockerarm, valve and valve spring, etc, which can produce strong vibration noise when its engine is rotated at high speed. Said invented IC engine rotating distribution device is formed from rotating distribution shaft, distribution groove, gas-resisting ring and sealing throat tube. Its distribution process is implemented in rotating state, so that is can make engine be up to 5000-8000 rpm and even higher, and have no distribution noise basically.
Description
Technical field: the present invention's " explosive motor rotation air distributing device " belongs to the explosive motor critical component.
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.
Goal 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 present invention's " 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.Technological scheme: its feature comprises:
1, the distribution cylinder cap is by up and down two forming (what generally adopt at present is an integral body) at two stripe shape intake and exhaust of following half cylinder head bottom surface Boulez air distribution hole half, (traditional is round), cylinder cap both sides Boulez exhaust port inlet hole, the installation gasoline motor spark plug in position is set, the mounting hole of diesel engine oil nozzle.
2, in the intermediate throughholes that up and down two half cylinder cap are formed rotation distribution axle is installed, 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 processes the distribution groove by valve timing diagram, and the choke ring is installed in the both sides of groove, and rotation distribution axle is a hollow shaft, 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, the sealing trunnion forms tight rotational slide sealing surface with rotation distribution axle under the spring force effect.Be installed into tracheae in suction tude one side, suction tude is made double layer construction, circulation cooling medium in the interlayer, adopt this method, on petrol engine, use, 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 the key index that exhaust emissions reaches Europe 3, Europe 4 standards.
5, rotation distribution axle, the choke ring, sealing trunnion parts should have grease channel, guarantee can not take place when high speed rotating the attrition surface phenomenon that degenerates.
6, upper and lower two half interior Boulez coolant guiding channels of cylinder head, the temperature that makes its rotation distribution parts is within the 80-150 degree.
Beneficial effect: owing to adopt technique scheme, explosive motor rotation air distributing device of the present invention, engine speed speed up, volume lightweight are become a reality, promptly can save fuel oil, reduce the engine production cost, reduce engine noise, can reduce the discharge amount of harmful matter Nox in the tail gas again.
Description of drawings: Fig. 1, Fig. 2 are structural representation of the present invention.
Embodiment: as shown in the figure:
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.
Claims (2)
1, a kind of " explosive motor rotation air distributing device " is characterized in that:
It comprises rotation distribution axle, the distribution axle is by the valve timing diagram processing distribution groove of each cylinder, the choke ring is installed in the groove both sides, and the cam that can drive monomer diesel oil high-pressure service pump, rotation distribution axle is installed in up and down in the circular hole that two half cylinder head form, the sealing trunnion that deploying pore is into arranged on following half cylinder head and be used to seal.
2, explosive motor rotation air distributing device as claimed in claim 1 is characterized in that:
