Description

The antiknock energy-saving engine

(1) technical field

The utility model relates to motor, particularly a kind of antiknock energy-saving engine.

(2) background technique

At present, motor both domestic and external no matter, its structure still is two mechanisms, five big systems, both crankshaft ﹠ connecting, distribution device, fuel system, cooling system, lubrication system, transmission system and electrical distribution system.Internal combustion engine as current widespread usage, around five big systems constantly from fuel saving, output power is big, exhaust gas purification good, Security is good etc., and the aspect is improved, the electrical distribution system of computer control motor and the advanced technology of fuel system have also successfully been realized, yet, the important step of motor, distribution device but still are mechanical transmission, thereby, show its deficiency day by day, its deficiency is:

1, complex structure, easy break-down

By the crank-driven timing gear, drive camshaft, push rod, rocking bar, press the certain hour angle through pillar, conduit, valve, spring and open and close valve, make the engine structure complexity, in addition, valve mechanism lubricated also will be added etc. separately, and the weight and volume of motor all can't be reduced, because of complex structure, thus when work easy break-down.

2, the distribution device reactive loss is big, waste fuel

Because complex structure, back and forth the weight of part is big, need powerful valve spring to remove to overcome the inertial force of these parts, therefore, the pressure of each valve spring (elastic force) mostly about 18.4-49kg (on average the pressure of each valve spring is at 34kg), adds mechanism's losses such as upper push-rod, rocking bar, can make motor in distribution device, cause reactive loss to reach 2%, and engine power is big more, and reactive loss is many more, waste fuel.

3, inlet and exhaust valve " is repeatedly opened " and is reduced engine power

Because the available engine distribution device is a mechanical transmission, inlet and exhaust valve is limited by the cam angle degree of camshaft, impossible instantaneous open and close valve simultaneously, is arranged some waste gas in order to make motor more, advance some mixed gass more, therefore, its inlet and exhaust valve does not run to top dead center or lower dead center Push And Release at piston during engine operation, and " the repeatedly opening " time all will be arranged, because " repeatedly opening " causes engine power to descend, and pinking takes place easily.

4, mechanical distribution device noise is big, and needs often to adjust valve operating clearence etc., and when serious, engine power descends, even can not work.

(3) summary of the invention

The technical problems to be solved in the utility model, provide a kind of Push And Release with the electromagnetic valve engine valve, without the mechanical driving part of camshaft, push rod, conduit, rocking bar, support and lubricating of this part parts, simultaneously, electromagnetic valve burner oil, time of ignition are regularly sprayed water in order to prevent pinking, to increase power to cylinder.

The technological scheme that adopts is:

The antiknock energy-saving engine comprises electromagnetic valve valve switching mechanism, regularly prevents pinking mechanism to the cylinder water spray.Described electromagnetic valve valve switching mechanism, comprise cylinder, valve, timing gear, CKP, solenoid valve, CKP is laid N crankshaft angles adapter coil by the timing rotor with around the timing rotor, and it is 360 °/N formation at interval.Timing rotor outer rim is provided with convex portion, the timing rotor is fixedly connected on the timing gear of motor, timing gear are engaged on the bent axle driving gear, N crankshaft angles adapter coil stationary is on the timing gear cover, solenoid valve is by fixed electromagnet, movable electro-magnet and electromagnet base are configured to, the electromagnet mounting is fixedly connected on the cylinder head, the valve of structure and valve stem as a whole, its valve and cylinder head assembling, valve stem passes the electromagnet mounting, be provided with valve spring in the electromagnet mounting, valve spring is sleeved on the engine valve stem in the electromagnet mounting, fixed electromagnet and movable electro-magnet are sleeved on the outer engine valve stem of electromagnet mounting, and fixed electromagnet is fixed on the electromagnet mounting, and fixed electromagnet is threaded in valve stem top with set distance under the movable electro-magnet.CKP is electrically connected transistor base, and the triode negative electricity connects magnet spool, constitutes electromagnetic valve valve switching mechanism.Described timing prevents pinking mechanism to the cylinder water spray, comprise engine cooling water pump, steam generator, steam nozzle, pressure regulator, vacuum transducer, engine cooling water pump connects engine water tank by pipeline, connect steam generator, steam generator is provided with water controller and steam pressure regulator, steam generator is installed on the gas exhaust manifold, steam generator is provided with the little steam pipe of corresponding each valve, nozzle is equipped with in little steam pipe termination, the opening time decision steam jet amount of nozzle needle, by computer control, vacuum transducer is housed on the suction tude, throttle position sensor, suction tude connects intake manifold.Detonation sensor, cooling-water temperature sensor are housed on the motor, sensor and starting motor, starting warming-up temperature, neutral switch starter all connect computer rapidly, computer can regularly send the water spray instruction, constitutes regularly to prevent pinking mechanism to the cylinder water spray.

Above-mentioned CKP can be electric current in the direct switching solenoid valve of breaker point device.

Above-mentioned crankshaft angles adapter coil can be the trigger signal that photodiode is formed switching circuit.

The good effect that the utility model is obtained:

1, only simple solenoid valve has replaced all driving mechanisms in the available engine distribution device, therefore, has reduced assembly process and cost, has dwindled the motor volume, has alleviated engine weight, and has been difficult for breaking down.

2, owing to cancelled mechanically operated distribution device, make valve spring not need excessive elastic force to overcome that part is many, the big inertial force that causes of weight, therefore, can reduce the reactive loss about 2% that motor is used to open and close valve, only this item, by existing 30,000,000 calculating of vehicle in use of China, can approximately save 30,000,000,000 yuan every year, add the reactive loss that aircraft, steamer and other motor are saved, social benefit is considerable.

3, because mechanical transmission drives the valve switching, limited by the cam of camshaft, valve is opened gradually and is closed, and the utility model switching valve is instantaneous, therefore, shorten repeatedly ETAD expected time of arrival and departure, made air inlet rapider, can advance some mixed gass to strengthen power more, simultaneously, can make waste gas get rid of some more, avoid pinking, fuel combustion better increased power, saved fuel.

Need not to adjust valve clearance and flight-line maintenance during 4, owing to work, also do not have mechanically operated noise simultaneously, therefore, engine operation is more steady, safer.

5, the door because valve opening solenoid is held one's breath, approximate instantaneous switching, improved intake and exhaust speed, therefore, the motor of identical horsepower, the utility model can dwindle inlet and exhaust valve, or reduction valve lifting height, can alleviate knocking of valve and seat, reduce the valve temperature, thereby improve motor working life.

6, because evaporation of water latent heat is higher, so therefore the heat that absorbs, produces the cooling effect than many many of gasoline, increased volumetric efficiency, the while also prevent pinking generation, increased power.
