Abstract
The utility model relates to a variable compression ratio engine, and belongs to the technical field of engine. The utility model solves the technical problem for providing the variable compression ratio engine which has simple structure and stable operation, and can continuously change the compression ratio in a wide range during work of the engine. The utility model solves the technical problem by adopting the technical scheme as follows: the variable compression ratio engine comprises a reverse piston, a spark plug, a fuel spray nozzle, and a piston, characterized in that: the spark plug and the fuel spray nozzle are arranged at one side of a cylinder wall of a combustion chamber which is formed between the reverse piston and the piston, and an air valve may also be arranged at one side of the cylinder wall of the combustion chamber which is formed between the reverse piston and the piston. The utility model has the beneficial effects that: the variable compression ratio engine has simple structure, stable operation, and easy realization; in addition, the variable compression ratio engine can continuously adjust the compression ratio in a wide range during work of the engine; and the variable compression ratio engine can have the advantages of fuel oil saving, larger power per liter, stronger power takeoff and more clean discharge.
Description
Technical field
The present invention relates to a kind of variable compression ratio engine, belong to technical field of engines.
Background technique
Variable compression ratio engine structure of the prior art is all very complicated, and great majority are all realized variable compression ratio by transforming mechanisms such as connecting rod or bent axle.But in engine operation, crankshaft-and-connecting-rod all is the strength member that bears enormous impact power, if in addition the transformation meeting brings the reliability of its work and seriously influences, also can bring the uneven shortcoming of cylinder wear by changing the variable compression ratio engine technology that connecting rod or bent axle change the stroke of motor.And the complicated crankshaft-and-connecting-rod of redesign production mechanism also can make cost of production increase.
Summary of the invention
Technical problem to be solved by this invention provides a kind of simple in structure, stable, variable compression ratio engine that can change compression ratio in engine operation continuously on a large scale.The technological scheme that technical solution problem of the present invention is taked is: the variable compression ratio engine that comprises reverse piston, spark plug, oil nozzle, piston, it is characterized in that: on casing wall one side of the firing chamber that forms between by reverse piston and piston spark plug and oil nozzle are installed, on casing wall one side of the firing chamber that can form between by reverse piston and piston valve are installed.
The invention has the beneficial effects as follows realization simple in structure, stable, easy, can in engine operation, adjust compression ratio continuously on a large scale, can allow motor saves more that fuel oil, power per liter are bigger, power output is stronger, discharging cleaning more.
Description of drawings Fig. 1 Fig. 2 is a structural representation of the present invention.
1 reverse piston, 2 firing chambers, 3 spark plugs, 4 oil nozzles, 5 valves, 6 pistons among the figure.
Embodiment
Below in conjunction with accompanying drawing the present invention is further elaborated.
The concrete working principle of motor is the same with traditional two strokes and four stroke engine, and difference only is to adjust compression ratio.Reverse piston 1 is installed on the piston 6 of motor, on casing wall one side of the firing chamber 2 that forms between by reverse piston 1 and piston 6 spark plug 3, oil nozzle 4 is installed.In order to make air inlet and exhaust more abundant, valve 5 can also be installed on casing wall one side of firing chamber.When engine operation the time at two strokes, also valve 5 can be installed, intake and exhaust are finished by the scavenging air valve and the outlet valve of cylinder bottom.The compression ratio of motor is by reverse piston 1 control, and oppositely piston 1 moves to piston 6 directions, and combustion chamber volume is reduced, and engine compression ratio increases, and oppositely piston 1 is when piston 6 opposite directions move, and combustion chamber volume increases, and engine compression ratio reduces.Because when adjusting reverse piston, do not influence the intake and exhaust and the oil spout igniting of motor, so can in engine operation, carry out large-scale compression ratio adjustment continuously.The method of regulating reverse piston can be hydraulic way, electronic mode, spiral way etc.
When engine operation in two stroke state, valve 5 intake and exhaust can be installed finish by the scavenging air valve and the outlet valve of cylinder bottom.Spark plug 3 and oil nozzle subtend are settled, and can form denseer mixed gas near spark plug like this, more help improving the combustion position of motor, make engine combustion more abundant, and power is stronger.Motor under two stroke state, work output power bigger, it is more steady to turn round, volume is littler.
Engine operation is when the four-stroke state, valve 5 should be installed, preferably adopt two double valve designs of advancing, oil nozzle is placed between two intake valves, subtend is installed exhaust valve, and spark plug can be installed between two exhaust valves relative to oil nozzle to reach near the denseer effect of mixed gas spark plug.And the inlet and exhaust valve subtend is installed and also can be made exhaust more abundant, improves combustion efficiency.
The invention provides a kind of realization simple in structure, stable, easy in sum, can in work, adjust the motor of compression ratio continuously on a large scale, can allow motor is saved fuel oil more, power per liter is bigger, power output is stronger, discharging cleaning more.
