What Causes a Diesel Vehicle to Stall While Driving?
1 Answers
Diesel vehicles stalling while driving may be caused by ice formation in the fuel leading to blockages, or there could be air leaks in the fuel line between the pump and the tank. If the vehicle is parked for too long, the diesel in the fuel line may flow back into the tank. Initially, the engine may start but then stall after a while as the fuel in the filter is depleted, allowing air to enter the system. Below are the functions of engine oil: 1. Friction Reduction: A sufficiently thick oil film separates the surfaces of moving parts, thereby reducing wear. 2. Sealing: Engine oil forms a seal between the piston rings and the piston, minimizing gas leakage and preventing contaminants from entering. 3. Rust Prevention: Lubricating oil adheres to part surfaces, protecting them from contact with water, air, acidic substances, and harmful gases. 4. Cushioning: When pressure in the engine cylinder rises sharply, the load on the piston, piston skirt, connecting rod, and crankshaft bearings increases suddenly. This load is transmitted and cushioned through bearing lubrication. 5. Cleaning: High-quality engine oil can carry away carbon deposits, sludge, and worn metal particles from engine components back to the oil pan. The flow of the oil also helps wash away dirt generated on the working surfaces of the parts.
