Abstract

The invention discloses an in-line synthesis type high-pressure oil supply pump control system which comprises an integral pump body, wherein the middle of a drive shaft is provided with cams matched with plunger pumps, and each plunger pump only supplies high-pressure oil to an electric control fuel injector. The in-line synthesis type high-pressure oil supply pump control system is characterized in that a part of a drive shaft, extending from an oil supply pump rear cover, is a rotor shaft, a circular hole of a signal regulating plate is matched with a column body on the oil supply pump rear cover, the signal regulating plate is provided with signal regulating plate end face sensor opposite to a rotor end face permanent magnet, a rotor pole iron detection sensor opposite to a rotor pole iron is arranged on a sensor bracket. An electronic control unit (ECU) receives signals from the rotor pole iron detection sensor and the signal regulating plate end face sensor which are connected with the ECU, and the processed signals are sent to the corresponding electric control fuel injector through a transmission line. The invention has the characteristics of simple structure, good generality, easiness in debugging, low cost and easiness in production, is especially suitable for application on an electric control diesel engine, and can also be applicable to other oil pumping fields.

Description

technical field

[0001] The invention belongs to the technical field of in-line plunger type oil pumps, in particular to an in-line synthetic high-pressure oil supply pump control system, which is widely used in multi-cylinder high-voltage electronically controlled diesel engines. Background technique

[0002] At present, on diesel engines, the in-line synthetic fuel injection pumps used are traditional mechanical and electronically controlled.

[0003] The traditional mechanical in-line fuel injection pump is mainly composed of fuel injection pump, governor, fuel supply advancer and so on.

[0004] The fuel injection pump is composed of a pump body, an oil pump mechanism, an oil quantity control mechanism and a transmission mechanism. This kind of fuel injection pump has low fuel injection pressure, low accuracy of controlling fuel injection, many subsidiary mechanisms, complex structure, high production cost and difficult debugging. The oil volume control mechanism has ge...
