Problems solved by technology
When the existing fuel injector leaks, the oil droplets are heated and evaporated on the cylinder, causing an explosion, and the safety of the equipment needs to be improved; The occurrence of abnormal wear conditions such as difficulty in starting, non-slack acceleration, and severe engine vibration caused by blockage will shorten the service life of the equipment; in addition, if the oil contains water, the water in the oil will dilute the gasoline and easily cause the plunger to rust Stuck and cause equipment failure

The invention provides a gasoline sprayer. The gasoline sprayer includes a cover, a pressure adjustment screw, super absorbent resin, a filtering device, and a flame retardant protective housing; a tappet is arranged inside a gasoline sprayer body; a pressure adjustment spring is arranged above the tappet; a spring cover is arranged on the pressure adjustment spring; a locking nut is arranged on the spring cover; and the locking nut is connected to the pressure adjustment screw. The flame retardant protective housing is additionally arranged outside the gasoline sprayer, and the use safety of the gasoline sprayer can be improved; the filtering device is additionally arranged in an air inlet pipe, the gasoline can be fully filtered in the filtering device, and the service life of the gasoline sprayer can be effectively prolonged; the super absorbent resin can effectively absorb water in gasoline, and the situation that the gasoline sprayer is in failure due to rust and jam of a plunger caused by the fact that water in the gasoline dilutes the gasoline can be prevented. The gasoline sprayer is simple in structure, is high in use safety, is long in service life, and is high in working reliability.
Description
technical field [0001] The invention relates to the field of automobile gasoline injector equipment, in particular to an injector. Background technique [0002] The fuel injector is a precision device with very high machining accuracy, which requires a large dynamic flow range, strong anti-clogging and anti-pollution capabilities, and good atomization performance. The working principle of the fuel injector is to receive the fuel injection pulse signal sent by the ECU , Precisely control the amount of fuel injection. When the existing fuel injector leaks, the oil droplets are heated and evaporated on the cylinder, causing an explosion, and the safety of the equipment needs to be improved; The occurrence of abnormal wear conditions such as difficulty in starting, non-slack acceleration, and severe engine vibration caused by blockage will shorten the service life of the equipment; in addition, if the oil contains water, the water in the oil will dilute the gasoline and easily ...
