Why does the Livina engine make a rattling sound during rapid acceleration?

[LeAbel]

Reasons for the rattling sound in the Livina engine during rapid acceleration are as follows: Rough engine operation: The abnormal sound caused by rough engine operation is accompanied by difficulty in starting, unstable operation after ignition, and rapid consumption of coolant. This abnormal sound is caused by premature fuel injection timing and should be addressed by readjusting the fuel injection advance angle. Delayed fuel injection timing: The exhaust pipe produces continuous backfire sounds along with black smoke during exhaust, and the exhaust pipe becomes overheated, making starting difficult. This abnormal sound is caused by delayed fuel injection timing and should be promptly corrected by adjusting the fuel injection advance angle. Diesel leakage from the fuel injector: The engine produces irregular abnormal sounds, sometimes knocking and sometimes backfiring, accompanied by unstable engine speed and intermittent black smoke emissions. This uneven abnormal sound is caused by diesel leakage from the fuel injector. When this phenomenon occurs, the fuel injector should be serviced.
