Description

Improvement of the structure of the nozzle cover

The present invention relates to a nozzle cover structure, in particular, a fuel pipe of a nozzle cover is connected to at least two oil inlet passages, and can be provided in a manifold having at least two oil inlet holes to increase the elasticity of use and the amount of oil supply.

In recent years, based on environmental protection and fuel-saving appeals, locomotives have been changed from traditional carburetor control to microcomputer-controlled injection engine systems. The injection engine system mainly collects locomotive data through various component sensors and provides signals to the fuel supply computer. After the computer has been operated, the signal is sent to the brake to control the injector, the ignition coil and the idle speed controller, etc., so that the engine operates normally.

As shown in FIG. 1 and in conjunction with FIG. 2, the nozzle cover 1 has a body 11 on which a screw hole 111 and a cylinder 112 connected to a tubing 113 are disposed. And the cylinder 112 has a passage connecting the oil pipe 113. When the nozzle cover 1 is to be assembled to the manifold 3, the two ends of the nozzle 2 are respectively disposed in the cylinder 112 of the nozzle cover 1 and the receiving groove 31 of the manifold 3, and the screw hole 111 of the nozzle cover 1 is provided. Corresponding to the position of the screw hole 32 of the manifold 3, it can be locked by a screw, and the nozzle cover 1 is connected to the oil supply computer through the power line to control the fuel nozzle to supply oil by the oil supply computer.

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 nozzle cover 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 modification effect of the consumer, and there is still a lack of improvement.

Therefore, the purpose of the creation is to increase the number of oil passages in the oil nozzle cover, so that the nozzle cover can be provided for at least two nozzles, and can be used for a manifold having two or more oil inlet holes. Increase the amount of fuel entering the manifold to improve engine efficiency.

In order to achieve the above object, the present invention proposes a structural improvement of a grease cap, which is provided in a manifold having two or more oil inlet holes, and comprises: a body having at least two through holes and at least a second screw hole, and can be locked by the screw hole corresponding to the manifold; at least two sockets are coupled to the base body and connected to the power supply line of the oil supply computer; and at least two cylinders are disposed at positions corresponding to the through holes And connecting a fuel pipe, the oil pipe has a passage, and an oil inlet passage communicating with the through hole is opened at a position corresponding to the cylinder at the passage.

Based on the above, the nozzle cover of the present invention can be provided with at least two nozzles by at least two cylinders, and the nozzles are correspondingly arranged in a manifold having at least two oil inlet holes, and at least two inserted through the sockets. The power cord is connected to the oil supply computer, whereby the fuel supply computer controls at least two nozzles to simultaneously inject fuel to increase the amount of fuel in the manifold, thereby achieving the effect of improving engine horsepower.
