What are the symptoms of engine cylinder leakage?

The engine with oil leakage in the cylinder line of Pacific automobile will have symptoms such as engine jitter, unstable idle speed and weak acceleration. There are many reasons that lead to the engine's weak acceleration, jitter and unstable idle speed, and the air leakage in the cylinder pipeline is only one of them. Too much carbon deposit in throttle, idle motor, intake valve, intake pipe and combustion chamber, spark plug and fuel nozzle will all cause such faults.

Cylinder pipeline and quantity of cylinder pipeline: 1. Cylinder line is also called high voltage line. As the name implies, the high-voltage line is responsible for transmitting high-voltage electricity from the high-voltage coil to the spark plug. An excellent set of high-voltage lines must have minimum current loss to avoid electromagnetic interference caused by high-voltage power transmission.

2. The number of cylinder pipelines is the same as that of engine cylinders. With the development of science and technology, many cars now have no cylinder line. The cylinder line and ignition coil are combined into one, and each cylinder has one ignition coil, which greatly reduces the volume and provides more convenient conditions for each cylinder to ignite independently.

Cylinder line detection: 1, multimeter detection: the automobile cylinder line resistance is generally several thousand ohms, and the automobile cylinder line resistance is generally 20,000 ohms during gear selection. The red and black probes of the multimeter are respectively connected to the two ends of the oil cylinder pipeline. If the reading displayed by the multimeter is between 1 and 20000 ohms, the cylinder pipeline is not open. If it is infinite, it means an open circuit.

2. Detecting the stylus: Install the cylinder line on the vehicle, start the vehicle, connect one end of the stylus with the vehicle body with a clamp, and move the other end of the stylus back and forth around the cylinder line for 5 to10 mm. If the stylus flashes, it means that the cylinder line is leaking.
