Abstract
The invention relates to a variable compression engine which comprises an engine. The variable compression engine is characterized in that a variable compression rod capable of extending into a cylinder combustion chamber to change the cylinder compressive ratio is arranged above an engine cylinder, the variable compression rod is connected with a drive mechanism controlling the variable compression rod to move up and down, and the drive mechanism is connected with an electronic control unit (ECU) sending a control signal to the drive mechanism. The variable compression engine is beneficial to outputting high torsion when the engine operates at low speed and improving the combustion efficiency of the engine.
Description
Technical field
The present invention relates to a kind of variable compression ratio engine.
Background technique
Motor in the market mostly is single diesel engine and petrol engine, though diesel engine has high torsion, average power per liter is low, and petrol engine need could be realized high power when running at high speed, and during the starting low speed driving, torsion is low, oil consumption is big.
Summary of the invention
The purpose of this invention is to provide a kind of variable compression ratio engine, export high torsion when this device helps time of engine low speed, and help improving engine combustion efficiency.
Technological scheme of the present invention is achieved in that and comprises motor, it is characterized in that: described engine cylinder top is provided with can stretch into cylinder chamber to change the scalable transformation ratio bar of cylinder chamber volume, and described transformation ratio bar is connected with the driving mechanism of its fore and aft motion of control.
Remarkable advantage of the present invention is: the one, and reasonable in design, the 2nd, realized that by the fore and aft motion of control transformation ratio bar motor not only has high torsion, high-power characteristics, but also can save automobile fuel consumption.

8 is that valve, 9 is that oil nozzle, 10 is spark plug among the figure
Embodiment
The present invention includes motor 1, it is characterized in that: described engine cylinder top is provided with can stretch into cylinder chamber 2 to change the scalable transformation ratio bar 3 of cylinder chamber volume, and described transformation ratio bar is connected with driving machine 4 structures of its fore and aft motion of control.
The work drive motor of above-mentioned driving mechanism is connected with to its car running computer that transmits control signal 5, and described car running computer input end is connected with speed checking apparatus for vehicle 7 with steam-cylinder piston rotating shaft crankshaft angles monitor 6 respectively by signaling line.
When vehicle during at low speed driving, steam-cylinder piston rotating shaft crankshaft angles monitor feeds back to car running computer with the Monitoring Data that the bent angle of its rotating shaft changes by tachometer, stretch into to the combustor inner cylinder chamber by the order control transformation ratio bar of car running computer when driving mechanism sends low-speed running, reduce the volume of firing chamber, allow the compression ratio of motor reach the high pressure ratio of diesel engine, thereby carry out compression ignite, reach high torsion.
When vehicle when running at high speed, steam-cylinder piston rotating shaft crankshaft angles monitor feeds back to car running computer with the Monitoring Data that the bent angle of its rotating shaft changes by tachometer, send order control transformation ratio bar when running up from the cylinder chamber return that rises by car running computer to driving mechanism, increase the volume of firing chamber, allow the compression ratio of motor become the low-pressure ratio of petrol engine again, thereby allow spark plug give me a little fuel oil vapour mixture, realize the high speed high power.
Owing in conjunction with the advantage of diesel engine and petrol engine, thereby realize that high torsion does power, low oil consumption.Though the present invention discloses as above with preferred embodiment; so it is not of the present invention in order to limit; have in the technical field under any and know the knowledgeable usually; in not breaking away from spirit and scope of the present invention; when can doing a little change and retouching, so protection scope of the present invention is as the criterion as the claim person of defining that look claims.
