Abstract

The utility model relates to a gasoline engine with multiple combustion centers, which belongs to the field of automotive fittings. The utility model is characterized in that an air cylinder cover of each cylinder body is provided with at least two or more than two igniters simultaneously; an ignition control circuit controls all the igniters in one cylinder body to carry out synchronous ignition; a definite distance A is spaced between every two igniters installed in one cylinder body; thus, multiple combustion centers can be formed inside one cylinder body, and the pressure of gas which is combusted in the cylinder body can be larger, the temperature is higher, the combustion speed is higher, and the purpose of the uniform deflagration can be reached; so the efficiency of the gasoline engine with multiple combustion centers can be greatly increased, the gasoline consumption is reduced, the discharge amount of waste gas can be reduced, and the environmental pollution can be abated.

Description

Many combustion centre petrol engine

The utility model relates to a kind of many combustion centre petrol engine.Belong to the auto parts machinery field.

Existing petrol engine is to light mixed gas with the igniter (spark plug) that is installed on the cylinder head, and mixture combustion expands and produces the work done of pressure compression piston.The mixed gas instantaneous expansion produces pressure during igniting, and pressure is big more, and it is big more to do work, if the velocity of combustion of mixed gas is fast more, then the swelling pressure are also big more.In order to improve velocity of combustion, people take two aspect technical measures usually: the one, and improve compression ratio and strengthen ignition energy.Initial stage, along with the raising of compression ratio, the corresponding raising of velocity of combustion, but when further improving compression ratio, the curve that velocity of combustion improves tends towards stability, and the raising compression ratio means that wasted work will increase.Therefore, the raising of compression ratio also is limited.Another kind method is set up two above centre electrodes on an igniter, to obtain the plural ignition spark of row.Though both forms are different, all be to increase ignition intensity in essence.Though said method is improving startability and igniting has certain effect aspect the reliability, but it is unsatisfactory aspect raising power and reduction oil consumption, its reason is: after the ignition spark energy reaches igniting basic demand (100-200mj), continue to improve ignition energy, from increasing the aspect of velocity of combustion, meaning is little.

The purpose of this utility model is to overcome the deficiencies in the prior art, invent a kind of in a cylinder block firing chamber, at least two or more igniters are housed simultaneously, separated by a distance between each igniter, and the whole spark plugs in each cylinder block are controlled by the igniter control circuit, simultaneous ignition takes place, in a cylinder, form many combustion centre, thereby make that unburned gas pressure is bigger in the cylinder block, temperature is higher, velocity of combustion is faster, until even deflagration, many combustion centre petrol engine that the efficient of motor is increased substantially.

The purpose of this utility model is to finish by following array structure: reach the ignition control circuit that is connected with high-tension transformer by cylinder block, cylinder head, igniter, high-tension transformer and form, it is characterized in that on the cylinder head of each cylinder block, at least two or more igniters are housed simultaneously, the whole igniter simultaneous ignitions in cylinder block of ignition control circuit control; Be installed between each igniter in the cylinder block phase mutual induction A that keeps at a certain distance away; Ignition control circuit by the whole igniters in the control cylinder block, is realized simultaneous ignition simultaneously.

Many combustion centre of the utility model petrol engine device working principle: in a cylinder block (5), two or more igniter (1,6) is installed simultaneously.Be installed in each igniter (1,6) in the cylinder, the igniter control circuit of all controlled igniter igniting is controlled simultaneously, guarantee the whole igniter simultaneous ignitions in this cylinder, like this when ignition control circuit sends firing command, several igniter simultaneous ignitions in the same cylinder block, several centers, firing chamber appear in moment simultaneously, consequently: on the one hand, flame travel shortens (shortening with how much radixes) significantly, and reduce with multiple period of combustion; On the other hand, the expanding gas mutual extrusion that several combustion centre form makes the interior unburned gas pressure of cylinder block bigger, and temperature is higher, and velocity of combustion is faster, until even deflagration, the efficient of motor is increased substantially.If each igniter in same cylinder has a spacer segment distance A between (1,6), its many combustion centre distribute even more in same cylinder block, and flame travel is even, during igniting, each combustion centre swelling pressure each other are also even, the work done better effects if.

The utility model can increase substantially petrol engine efficient, reduces per unit kilometer oil consumption, significantly reduces the content that automobile exhales pernicious gases, the guard ring environment pollution.

Below in conjunction with accompanying drawing, be described further with regard to the utility model structure, but the utility model protection domain is not limit this example.

Fig. 1 is the structural representation of cylinder block firing chamber and igniter in many combustion centre of the utility model petrol engine.

Fig. 2 is a kind of ignition control circuit schematic diagram that uses at many combustion centre of single cylinder petrol engine.

Embodiment 1: be 50 milliliters two-stroke motorcycle petrol engine or be on 125 milliliters the 4 stroke motorcycle petrol engine in air displacement in air displacement, by structure shown in Figure 1, two igniters (1,6) with certain intervals distance are installed symmetrically on cylinder head (3); By ignition control circuit shown in Figure 2, with universal product condenser type contactless electron point control device CDI (2), two the high voltage variable devices (B1, B2) that are connected in series, high-tension transformer (B1, B2) are connected with igniter (6) with igniter (1) respectively.During igniting, high voltage variable device (B1, B2) is that two igniters (1,6) provide high-tension current, make igniter (1,6) that simultaneous ignition take place, thereby moment forms two combustion centre in a cylinder block, the expanding gas of two combustion centre's formation pushes mutually, piston (4) work done, engine efficiency improves by a larger margin, realizes goal of the invention.

This practical ignition control circuit removes and adopts shown in Figure 2ly by a condenser type contactless electron point control device CDI (2), controls outside two high-tension transformer circuit connecting modes; Can also adopt by a condenser type contactless electron point control device CDI (2), control a high-tension transformer circuit mode, also can finish simultaneous ignition with two or more high pressure windings.Therefore, as long as ignition control circuit of the present utility model can guarantee all moment generation simultaneous ignitions of whole igniters in a cylinder block.For the multi-cylinder petrol engine, as long as ignition control circuit can be controlled whole igniter simultaneous ignitions of installing in each cylinder block respectively.

The utlity model has simple in structure, enforcement convenience, can increase substantially petrol engine efficient, reduce oil consumption, reduce discharge amount of exhaust gas, alleviate environmental pollution, have bigger economic benefit and social benefit.
