Description

Manifold structure with double injection holes

The present invention relates to a manifold structure, and more particularly to a fuel injector assembly for more than one fuel pump.

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 engine manifold of the existing vehicle can only be connected to a single injection device, and it is impossible to increase the intake air amount while increasing the fuel injection amount, it is difficult to achieve the expected conversion effect of the consumer, and in addition, the injector needs to be cleaned frequently. The burden of maintenance.

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 oil inlet smoothness by adjusting the angular position of the two injector housings so that the nozzles of the assembled nozzles can correspond exactly to the two oil inlet holes of the cylinder.

In order to achieve the foregoing objective, the present invention provides a manifold structure having a double fuel injection hole, 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 two ends of the passage, and the inlet The air end system is connected with the throttle valve, and the air outlet end is connected with a cylinder, and the receiving hole of the fuel injector receiving seat is directly penetrated through the passage, and can be separately assembled on the two fuel injection nozzles. When the two injector nozzles are seated, the nozzles of the two injectors correspond to the oil inlet holes of the cylinders, thereby enabling the manifold to add fuel injectors according to the use requirements to increase the fuel injection amount and The oil is smooth and the engine horsepower is increased.
