specific Embodiment approach 1

[0007] Specific implementation mode one: the following combination figure 1 , figure 2 Describe this embodiment, this embodiment is made up of oil pump 1, main oil tank 2, auxiliary oil tank 3, oil valve 4, a plurality of measuring cylinders 5, controller 6, square wave generator 7, oil tank connecting pipe 8 and oil separator 9, many A measuring cylinder 5 is located above the auxiliary oil tank 3, and the bottom ends of the plurality of measuring cylinders 5 are connected together. The two ends of the oil valve 4 are respectively connected with the plurality of measuring cylinders 5 and the auxiliary oil tank 3. The two ends of 8 communicate with the auxiliary oil tank 3 and the main oil tank 2 respectively, the suction side of the oil pump 1 communicates with the main oil tank 2, the discharge side of the oil pump 1 communicates with the oil separator 9, and one output end of the controller 6 communicates with the power end of the oil pump 1 The other output end of the co...

specific Embodiment approach 2

[0019] Specific implementation mode two: the following combination figure 1 This embodiment is described. The difference between this embodiment and Embodiment 1 is that n fuel injectors 10 are cleaned at the same time, n square wave output ends 7-1 are respectively connected to n electrical connectors 10-1, and n The oil outlet joints 9-1 communicate with the n oil inlets 10-2 respectively, and the n oil injectors 10 are respectively placed above the n measuring cylinders 5, and the others are the same as the first embodiment.

Abstract

The invention discloses a washing and detecting instrument for an automobile oil spray nozzle, and relates to a detecting device of the automobile oil spray nozzle free of ultrasonic cleaning, which aims to solve the problems of the existing devices that the washing and detecting of the automobile oil spray nozzle cannot be operated on the same machine and that the cost is high. A plurality of measuring cylinders are positioned on the upside of an auxiliary oil tank; the bottoms of a plurality of measuring cylinders mutually communicate with each other; both ends of an oil valve respectively communicate with a plurality of measuring cylinders and the auxiliary oil tank; the auxiliary oil tank is positioned on the upside of a main oil tank; both ends of the connecting pipe of the oil tank respectively communicate with the auxiliary oil tank and the main oil tank, a suction side of an oil pump communicates with the main oil tank; the discharge side of the oil pump communicates with an oil distributor; one output end of a controller is connected with the power end of the oil pump; the other output end of the controller is connected with the input end of a square wave generator; the square wave generator outputs the square wave of 10Hz to 120Hz when cleaning and detection are carried out. The cleaning and detection of the automobile oil spray nozzle can be completed by one instrument. Therefore, the operation is simple and the cost is low.

Description

technical field [0001] The invention relates to a detection device for an automobile fuel injection nozzle free from ultrasonic cleaning, which can integrate the cleaning and detection functions of the fuel injection nozzle of an electric jet engine. Background technique [0002] For modern mechatronic new cars, especially electric control and electric injection vehicles, when the fuel injectors travel a certain mileage or use low-quality gasoline, the fuel injectors will stick and block in a short period of time, affecting normal operation. The running and normal fuel injection volume will cause difficulty in starting the engine, unstable operation, flameout at idle speed, and poor acceleration performance. If the fuel injector is not cleaned for a long time, carbon deposits and grease will be formed on the intake valve, resulting in insufficient air intake of the engine, resulting in insufficient engine power, and even causing the engine to tremble, leading to abnormal wea...
