Is it advisable in winter time to pour petrol into the tank of a diesel engine bus?
Show the correct answer
Correct answer
C. No, because it leads to a damage of the power supply system and the engine.
Explanation
The question is about adding petrol to the fuel tank of a bus with a diesel engine in winter. It is not recommended, because it leads to damage to the fuel system and the engine - answer C.
The Road Traffic Act requires a vehicle to be maintained so that using it does not endanger safety. In the past, drivers added petrol to diesel fuel so that it would not thicken in frost, but modern injection systems work at very high pressure and are lubricated only by the fuel itself - petrol reduces this lubrication and destroys the pump and the injectors. That is why answers A and B are wrong, regardless of the amount of petrol added. In winter you fill up with winter or arctic diesel fuel, which is available at filling stations in the right season, and in very low temperatures you can use an additive recommended by the manufacturer.
