Where is the car fuel injector located?
1 Answers
Car fuel injectors are located either on the intake manifold or on the cylinder head. If the injector is on the intake manifold, the engine uses multi-point fuel injection; if it's on the cylinder head, the engine employs direct fuel injection; and if the engine has two sets of injectors, it utilizes a hybrid injection system. The fuel injector is an electromagnetic valve that controls fuel spray into the engine by opening and closing, promoting more efficient fuel combustion. Common fuel injector issues and solutions: 1. Clogged injector nozzle: Polish with chromium oxide on a flat surface; replace the needle valve if the cylindrical surface is severely worn. 2. Poor sealing: Apply chromium oxide or toothpaste to the sealing band at the needle valve end. 3. Piston wear: Replace the piston.
