How to solve the ignition advance angle of cylinder 1 being less than 5?
2 Answers
You can use the method of a special distributor housing to adjust the ignition advance angle. The working principle of an automobile cylinder is to guide the piston to perform linear reciprocating motion within the cylinder. In the engine cylinder, air converts thermal energy into mechanical energy through expansion. In the compressor cylinder, gas is compressed by the piston to increase pressure, providing a power source.
I've dealt with this type of issue before. The ignition advance angle of cylinder 1 being less than 5 degrees is a classic symptom, likely stemming from a faulty crankshaft position sensor or abnormal camshaft sensor signal. I've encountered many car enthusiasts complaining about engine shaking and increased fuel consumption, with the root cause lying here. First, check the wiring and connectors of these sensors, as they often develop poor contact due to aging circuits. Before getting hands-on, invest in a cheap OBD scanner (around a few dozen bucks) to read the trouble codes and pinpoint the problematic component. If you don't have the equipment, borrow tools from a repair shop. If you're doing it yourself, remove the sensor for cleaning or replacement. Don't overlook carbon buildup during regular maintenance – frequent short-distance driving can dirty the throttle body and fuel injectors, affecting signal reading. After repair, the engine will run much smoother with reduced noise and emissions. Developing a habit of periodic cleaning saves money and hassle. For example, running at high RPMs on the highway every 10,000 km effectively clears carbon deposits.
