The reasons for starter freewheeling: 1. Check whether the starter drive gear and engine flywheel ring gear are excessively worn or have missing teeth; 2. Verify the integrity and effectiveness of the friction clutch, and whether the spring tension meets the specified value; 3. Due to prolonged use and frequent exposure to high temperatures, the starter shift fork is prone to fatigue, distortion, and loss of performance. When starting the engine in a cold or low-temperature condition, freewheeling may occur. If the engine is restarted after a 15-second pause as specified, the freewheeling phenomenon may persist. Troubleshooting methods: 1. Disassemble and clean the starter, visually inspect the wear on the shift fork and shift fork ring for excessive wear or breakage, and repair or replace if necessary; 2. While checking the performance of the friction clutch, also inspect the spring tension, and replace if it falls far below the required specification; 3. Examine the wear on both the starter drive gear and the engine flywheel ring gear, or measure the tooth taper with specialized tools. Replace if excessively worn, and perform welding repairs if cracks are found.

The clutch is located between the engine and the transmission, acting as a switch for power transmission between them. It is a transmission structure that can both transmit and cut off power. Precautions for clutch usage are: 1. The clutch must be thoroughly cleaned before installation to remove anti-rust grease and debris; 2. The clutch can be installed coaxially or on separate shafts, but axial fixation is mandatory; 3. For wet electromagnetic clutches, lubricating oil must be added between the friction plates during operation; 4. Power supply and control circuits, the clutch power supply is DC 24 volts; 5. When installing a jaw-type electromagnetic clutch, a certain gap must be ensured between the end face teeth to prevent grinding during idling.

How to Clean a Car Fuel Injector?

Car fuel injector cleaning steps are: 1. Hang the cleaning device on the front hood of the car; 2. Locate the engine's fuel supply and return lines; 3. Disconnect the return line from the engine, select an appropriate adapter to plug the return line; 4. Connect the fuel supply line to the outlet of the cleaning device; 5. Open the fuel tank cap and remove the fuel pump fuse to stop the fuel pump operation. The fuel injector is a simple solenoid valve. When the solenoid coil is energized, it creates suction, lifting the needle valve to open the injector nozzle. Fuel is sprayed at high speed through the annular gap between the needle valve tip and the nozzle, forming a mist for optimal combustion.
