What Are the Causes of Difficulty in Hot Starting?
1 Answers
Reasons for difficulty in hot starting: 1. Air leakage in the intake system; 2. Fuel pressure is too low; 3. Air filter is clogged; 4. Faulty coolant temperature sensor, incorrect ignition timing, broken wiring from the starter switch to the ECU, or too low cylinder compression pressure, etc. For normal engine starting, four conditions must be met: sufficient ignition energy, appropriate mixture concentration, correct ignition timing, and normal cylinder compression pressure. If any one of these conditions is not met, it will result in the engine failing to start or having difficulty starting. If the issue is caused by excessive carbon deposits or impurities in the fuel injector, a cleaning agent can be used to clean it, ensuring smooth fuel injection and allowing the engine to start. Regular maintenance and timely repairs are essential to ensure stable, comfortable, and safe driving.
