Engine wire harness of V-shaped sixteen-cylinder four-ECU electronic injection machine

Abstract

The invention relates to an engine wire harness of a V-shaped sixteen-cylinder four-ECU electronic injection machine, and the wire harness comprises a main wire harness, a first slave wire harness, asecond slave wire harness and a third slave wire harness which, wherein the first, second and third slave wire harnesses are connected with the main wire harness through an adapter. The main wire harness comprises ten groups of wire harnesses, including camshaft position sensor wire harnesses, one end of each of which is connected with a camshaft position sensor joint; and water temperature sensorwire harnesses, one end of each of which is connected with a water temperature sensor joint, wherein the other ends of the ten groups of wire harnesses are respectively connected with a second main ECU plug-in connector. The main wire harness also comprises nine groups of wire harnesses, including oil pressure sensor wire harnesses, one end of each of which is connected with an oil pressure sensor joint; external line adapter wire harnesses, one end of each of which is connected with an external line adapter, wherein the other ends of the nine groups of wire harnesses are connected with a first main ECU plug-in connector, and the first main ECU plug-in connector and the second main ECU plug-in connector are connected with the main ECU. According to the invention, the engine with a large number of cylinders can be controlled, and the problem that an existing single ECU or double ECUs cannot be suitable for controlling a V-shaped sixteen-cylinder electronic fuel injection engine is solved.

Description

technical field [0001] The invention relates to an electric jet engine, in particular to a V-type sixteen-cylinder four-ECU electric jet engine wiring harness. Background technique [0002] The electronic control unit (ECU) is the main control device of the electronically controlled engine. Its function is to calculate, process, and judge the information input by various sensors according to the programs and data stored in it, and then output instructions to provide fuel injectors. An electrical pulse signal of a certain width is used to control the fuel injection quantity. At present, EFI engines are basically controlled by a single ECU or double ECUs, and correspondingly, a set of engine wiring harness is required, that is, the assembly of various lines of the engine electronic control system. For example, CN205638712U discloses "a V-type double ECU electronically controlled engine wiring harness layout structure", which includes a main ECU, a slave ECU, and a first group...
