Embodiment Construction
[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0050] refer to Figure 1-3 , a V-type twelve-cylinder two-ECU electric injection four-valve engine wiring harness, including a main wiring harness and a slave wiring harness connected to the main wiring harness through an adapter. The main wiring harness includes:
[0051] Camshaft position sensor wiring harness 2 connected to camshaft position sensor connector 1 at one end;
[0052] A first VCV valve wiring harness 4 connected at one end to the first VCV valve connector 3;
[0053] The first rail pressure sensor wiring harness 8 connected to the first rail pressure sensor connector 7 at one end;
[0054] An intake pressure / temperature sensor wiring harness 10 con...

The invention discloses a V-shaped twelve-cylinder two-ECU electronic injection four-valve engine wire harness. The V-shaped twelve-cylinder two-ECU electronic injection four-valve engine wire harness comprises a main wire harness and an auxiliary wire harness connected with the main wire harness through an adapter, and the main wire harness comprises a camshaft position sensor wire harness, a first VCV valve wire harness, a first rail pressure sensor wire harness and a crankshaft sensor wire harness, and one end of the camshaft position sensor wire harness is connected with a camshaft position sensor connector; one end of the first VCV valve wire harness is connected with a first VCV valve connector; one end of the first rail pressure sensor wire harness is connected with a first rail pressure sensor connector; and one end of the crankshaft sensor wire harness is connected with a crankshaft sensor connector. Parts of wire harnesses in the four-valve cylinder cover adopt high-temperature corrosion resistant special wire harnesses, wire outlets are sealed by high-temperature resistant and corrosion resistant rubber protective sleeves, and the wire outlets of the wire harnesses are wound by special adhesive tapes to ensure the sealing of the protective sleeves and the wire harnesses after the cylinder cover is installed. The phenomenon that the wire harnesses located in the cylinder cover make contact with engine oil for a long time and is damaged in a high-temperature environment is avoided, and the protective sleeves effectively solve the problems that the sealing performance is poor, and the engine oil seeps out of the wire outlets.
Description
technical field [0001] The invention relates to the technical field of electronic injection engines, in particular to a wiring harness of a V-type twelve-cylinder, two-ECU, electronic-injection four-valve engine. Background technique [0002] The multi-valve engine is one of the effective measures to increase the power per liter, improve the power and sensitivity of the engine, improve the fuel consumption rate and reduce exhaust pollution at the same time, but compared with the two-valve engine, the four-valve engine has a built-in fuel injector , so part of the wiring harness needs to be inside the cylinder head. [0003] In the existing four-valve engine, part of the wiring harness located in the cylinder head has a high internal temperature and is in contact with the engine oil, so the damage to the wiring harness is relatively large, and the sealing is poor, and the oil often leaks from the outlet. ooze. Contents of the invention [0004] The purpose of the present ...
