Abstract
The invention provides a V-shaped eight-cylinder double-ECU electric engine harness. The V-shaped eight-cylinder double-ECU electric engine harness comprises a one-cylinder oil sprayer joint, a two-cylinder oil sprayer joint, a three-cylinder oil sprayer joint, a four-cylinder oil sprayer joint, a five-cylinder oil sprayer joint, a six-cylinder oil sprayer joint, a seven-cylinder oil sprayer joint, an eight-cylinder oil sprayer joint, an intake temperature pressure sensor joint, a machine oil temperature pressure sensor joint, a first rail pressure sensor joint, a crankshaft rotating speed sensor joint, a second rail pressure sensor joint, a cam shaft rotating speed sensor joint, a fuel metering unit sensor joint, a water temperature sensor joint and leads for respectively connecting with all the devices, and further comprises a first fulcrum, a second fulcrum, a third fulcrum, a fourth fulcrum, a fifth fulcrum, a sixth fulcrum, a seventh fulcrum, an eight fulcrum, a main ECU plug and a slave ECU plug. The V-shaped eight-cylinder double-ECU electric engine harness is simple in structural distribution, prevents renewed development of ECU under the precondition of satisfying use requirements, reduces the design cost and period, and improves the economy.
Description
technical field [0001] The invention belongs to the technical field of electronically controlled engine wiring harness assembly structure, and in particular relates to a V-shaped eight-cylinder dual-ECU electronically controlled engine wiring harness. Background technique [0002] 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 the The fuel injector provides an electric pulse signal of a certain width to control the fuel injection quantity. [0003] The current electronically controlled engines are all controlled by a single ECU, which requires a set of engine wiring harness, which is the assembly of various lines of the engine electronic control system. However, the number of cylinders controlled by a single ECU is limited, and sometimes it is necessary to ...
