Abstract

The utility model relates to a gasoline engine, which has four strokes, mixed gas-electric controlled igniting, electronic injection, water cooling four-cylinder engine, and adopts the structure having the main components such as a crankshaft, a connecting rod, a piston, a cylinder jacket, an air inlet/exhaust valve and a machine body. An air meter regulator is mounted on an air inlet pipe, and the air meter regulator can quantitatively feed the mixed air entering an cylinder. The working volume of a single-cylinder cylinder jacket volume of the gasoline engine is 1000ml, when the air meter regulator is manufactured into a single-cylinder with 800ml air inlet each time, the combustion chamber volume corresponding to a cylinder cover is manufactured into 67ml. When the air meter regulator is manufactured into a single-cylinder with 400ml air inlet each time, the combustion chamber volume corresponding to a cylinder cover is manufactured into 34ml. The air supply of the gasoline engine is of between 800ml to 400ml, and the corresponding combustion chamber volume number is the air supply to be divided by 12. An air negative pressure switch is mounted at the air inlet pipe, only does the air inlet achieve the negative standard, the gasoline engine can work normally, and the utility model is a gasoline engine which can save gasoline.

Description

Petrol engine

Affiliated technical field

The utility model is a kind of dynamic power machine of burns gasoline, and is fuel-efficient petrol engine.

Background technique

Petrol engine in the world is because be subjected to the restriction of detonation, so compression ratio is low, because compression ratio equates that with expansion ratio so the chance of combustion gas acting is just few, the efficient of petrol engine is just low at present.

Summary of the invention

The utility model provides a kind of compression ratio 12: 1 and the petrol engine of expansion ratio extra-high-speed.

The technological scheme that its technical problem that solves the utility model adopts is: employing be bent axle, connecting rod, piston, cylinder barrel, structure, also adopted inlet and exhaust valve, the mixed steam electronic ignition, four cylinders, EFI, four-stroke, the structures the same such as computer control with the regular gasoline machine, this novel inventive point is, a quantitative air device is installed on suction tude, quantitative air device energy weight feed enters the air of cylinder, 1000 milliliters of the swept volumes of this novel single cylinder cylinder barrel, when this machine manufactured 800 milliliters of each air inlets of single cylinder when the quantitative air device, the combustion chamber volume on the corresponding cylinder cap manufactured 67 milliliters.When the quantitative air device manufactures 400 milliliters of each air inlets of single cylinder, corresponding cylinder cap upper combustion chamber volume manufactures 34 milliliters, this machine can select to determine any one air demand milliliter number between 800 milliliters-400 milliliters of the each admission of single cylinder, and it is exactly the milliliter number of cylinder cap upper combustion chamber that this air demand milliliter number removes last 12.This machine is because the ensemble average temperature is low, so be set at compression ratio 12: 1.Suction tude from valve more nearby, an air negative pressure electric switch is installed, when petrol engine rotates steam inlet pipe when reaching the negative pressure standard, circuit is connected, the low voltage winding of the electric inlet point fire coil of storage battery, petrol engine work, when intake pipe negative pressure was not up to standard, circuit was obstructed.

The beneficial effects of the utility model are: because increased the expansion ratio of combustion gas, equaled to strengthen combustion gas and promoted the chance that piston does work, so this petrol engine is fuel-efficient.

Description of drawings

Fig. 1 is the expansion ratio schematic representation, and combustion gas is under the situation that volume and pressure equate, left side downlink is the expansion working volume of regular gasoline machine, and the right downlink is an expansion acting volume of the present utility model, among the figure 1, the certain high-pressure gas of volume; 2, descent of piston volume; 3, regular gasoline machine piston allowance for expansion; 4, piston allowance for expansion of the present utility model.Fig. 2 is a theory structure schematic representation of the present utility model.The component that belonging to uniform-charge Otto-engine among the figure all has do not have picture, and the component that draw all are the component relevant with the utility model feature.Among the figure 1, bent axle; 2, connecting rod; 3 pistons; 4, cylinder barrel swept volume; 5, cylinder barrel; 6, cylinder cap upper combustion chamber; 7 cylinder caps; 8, quantitative air device; 9, proportioner axle; 10, air negative pressure electric switch; 11, electric wire; 12, electric wire; 13, spark coil; 14, storage battery; 15, body; 16, suction tude; 17, camshaft.

Embodiment

Body 15 bent axle 1 that is dynamically connected, bent axle 1 connecting rod 2 that is dynamically connected, connecting rod 2 piston 3 that is dynamically connected, piston 3 is linear reciprocating motion in cylinder barrel 5, cylinder barrel swept volume 4 is volumes that combustion gas promotes piston 3 actings, cylinder cap 7 is arranged above the cylinder barrel 5, cylinder cap upper combustion chamber 6 is arranged on the cylinder cap 7, be equipped with quantitative air device 8 on the suction tude 16, proportioner axle 9 connects camshaft 17, also be equipped with air negative pressure electric switch 10 on the suction tude 16, air negative pressure electric switch 10 electric wires 11 connect storage battery 14, and air negative pressure electric switch 10 also passes through the low-voltage circuit of electric wire 12 tie point fire coils 13.These more novel component that all must have with uniform-charge Otto-engine have not just been explained in the present embodiment.
