Description

Manifold structure for at least dual injector settings

The present invention relates to a manifold structure, especially one that can be used for more than one fuel injector assembly, and can shorten the distance of fuel entering the engine cylinder and increase the fuel supply.

Press, the engine combustion cycle is carried out in the cylinder. During the combustion process of the engine, the engine piston is first actuated to generate vacuum suction. The gasoline in the carburetor is atomized into the cylinder through the nozzle and then mixed with the air. Then, the ignition system transmits current to the spark plug to pass the spark gas through the spark plug. When the ignition is completed, the flame begins to propagate outward in the form of combustion pressure waves. Therefore, the intake rate of the oil and gas affects the engine horsepower. The key to size.

However, the traditional use of the engine piston to generate vacuum attraction, and passively pumping gasoline into the engine cylinder of the carburetor, not only the oil and gas mixing efficiency is low, but also the power efficiency is not high, but also consumes Oil and exhaust gas pollution, etc., so some operators have developed a borrowing computer control in view of the lack of traditional engine operation mode, actively injecting gasoline directly into the engine cylinder from the nozzle, and then combusting the output with the air in the cylinder. In the way of horsepower, this method has high oil-gas mixing efficiency and high power output efficiency, and can achieve the effect of saving fuel and reducing exhaust gas pollution.

However, although the injection device that actively controls the injection of gasoline into the engine cylinder by the driving computer has the above-mentioned many advantages, the injector is a very precise oil control system, and has a relative relationship with the horse's horsepower and the idling speed, once the injector is in a nozzle. Failure or blockage may cause the vehicle to malfunction. Therefore, the injector must be cleaned and maintained frequently, which increases the maintenance cost. In addition, some consumers increase the horsepower. The most common way to modify the air intake is to increase the air intake flow. When it is detected that the air intake amount is increased, the fuel injection amount of the fuel injector is relatively increased to meet the set mixing ratio. If the air intake amount is too large and the fuel injection amount is insufficient, the engine may not operate smoothly. The opposite effect.

In view of the fact that the manifold of the existing vehicle can only be connected to a single injection device, and it is impossible to increase the amount of intake air and increase the amount of fuel injection, it is difficult to achieve the expected conversion effect of the consumer. In addition, the cleaning of the injector needs frequent cleaning and maintenance. The burden on it.

Therefore, the purpose of the present invention is to increase the amount of oil supply by adding the number of nozzle holders of the manifold body so that the manifold can be provided with more than one injector.

Another object of the present invention is to improve the engine efficiency by adjusting the angular position of the injector housing so that the nozzle of the assembled injector can be closer to the inlet opening of the engine cylinder.

To achieve the foregoing objective, the present invention provides a manifold structure for at least a dual injector, which is formed in the interior of the manifold body to form a passage, and an intake end and an outlet end are respectively formed at the two ends of the passage. The intake end is connected to the throttle valve, and the outlet end is connected to a cylinder, and the first injector receptacle is disposed at the rear end of the manifold body, and the first injector receptacle has a second nozzle seat is disposed between the first nozzle housing and the engine cylinder, and the second nozzle housing has a through passage. a hole, and the outlet of the receiving hole of the second nozzle housing is close to the position of the inlet port of the engine cylinder, thereby enabling the manifold to add a nozzle according to the use requirement, and through the second The angle of the nozzle housing reduces the distance between the fuel injectors of the assembled injectors entering the intake port of the engine cylinders, and increases the fuel injection volume and improves the oil inlet smoothness to achieve the effect of improving engine horsepower.
