What Causes Blue Smoke from Diesel Vehicles?
1 Answers
Reasons for blue smoke from diesel vehicles: 1. Use of unqualified fuel or failure to change diesel for a long time, resulting in overly thin diesel and incomplete combustion; 2. Starting the engine with a large throttle when cold; 3. Poor quality of the mixed gas involved in combustion, or failure to replace aged or damaged filters; 4. Wear of the guide tube and valve during operation, causing excessive clearance between them, which leads to excessive engine oil being sucked into the combustion chamber from the rocker arm chamber during the intake process; 5. The piston ring being stuck in the ring groove due to carbon deposits, losing its elasticity and failing to function properly. If necessary, replace the piston ring or remove it to clean out the carbon deposits.
