What are the reasons for a diesel engine suddenly stalling?
1 Answers
The reasons for a diesel engine suddenly stalling are as follows: 1. Poor operation of the low-pressure fuel system: Before stalling, the diesel engine's speed gradually decreases, but the engine sound remains normal, and the exhaust gas color shows no abnormalities, yet it can still lead to sudden stalling. 2. Presence of water in the diesel fuel: This may cause the diesel engine's speed to become unstable before stalling, with white smoke coming from the exhaust pipe, leading to sudden stalling during operation. 3. Damaged cylinder head gasket: If the diesel engine continues to emit white smoke and stalls or fails to start after removing water, the cylinder head gasket may need to be replaced before testing the engine again.
