What Causes a Diesel Vehicle's Exhaust Pipe to Spray Engine Oil?
1 Answers
Diesel vehicle's exhaust pipe spraying engine oil can be attributed to the following reasons: 1. Excessive clearance: Natural wear of the power unit leading to excessive clearance between the piston rings and cylinder liner. 2. Excessive pressure: Overfilling of engine oil causing excessive pressure in the engine compartment. 3. Fault issues: Problems with the piston pin and cylinder liner. 4. Poor sealing: Severe wear or poor sealing between the valve stem and valve guide. A diesel engine is an engine that burns diesel fuel to obtain energy release. Its working process shares many similarities with gasoline engines, with each working cycle also going through four strokes: intake, compression, power, and exhaust.
