What is the reason for the Roewe RX5 not responding and making a clicking sound when starting?
1 Answers
Roewe RX5 not responding and making a clicking sound when starting indicates that the starter is working, but the engine is not. Possible causes include circuit or electronic faults, fuel system faults, etc. Below is an introduction to ignition-related information: Traditional Ignition: The working process of a mechanical ignition system involves the crankshaft driving the distributor shaft to rotate. The cam on the distributor shaft turns, causing the primary contacts of the ignition coil to open and close, generating high voltage. This ignition high voltage is then directed through the rotor on the distributor shaft to the spark plugs of each cylinder in the required sequence, where the spark plugs emit sparks to ignite the gas in the combustion chamber. Electronic Ignition: The electronic ignition system is completely different from the mechanical ignition system. It includes an electronic control device for ignition, which contains a map (MAP) of ignition control curves required for various engine operating conditions. A series of sensors, such as the engine speed sensor, intake manifold vacuum sensor (engine load sensor), throttle position sensor, and crankshaft position sensor, are used to determine the engine's operating state.
