What Are the Reasons for Difficult Starting and White Smoke Emission in Diesel Vehicles?

[ODominic]

Reasons for difficult starting and white smoke emission in diesel vehicles: 1. Low engine temperature: If white smoke appears during startup in winter, it is generally due to the engine temperature being too low and not yet reaching optimal conditions; 2. Water in the fuel supply system: If placing your hand behind the exhaust pipe results in water droplets forming when white smoke passes over your hand, it indicates the presence of water in the fuel supply system; 3. Low air pressure in the engine cylinders: If the engine emits white smoke at low temperatures and black smoke when warmed up, it suggests that the air pressure in the engine cylinders is too low; 4. Low fuel injection pressure: If the engine emits grayish-white smoke and the vehicle experiences weak acceleration after starting, it indicates that the pressure in the fuel injection system is too low.
