There are a few different views on what happens if petrol is put into a diesel car, ranging from "this is horrible and will ruin the engine" through "if diesel is put in a petrol engine, it will run but misfire" and "it does depend on the make and model of the car" to, most commonly "petrol will kill a diesel engine; don't start it, have it towed to your mechanic, and have him drain the tank and the fuel lines."
Modern diesel engines use the diesel fuel as lubricant for the high pressure pump. The engine itself will run on petrol but it is only a short period of time before the pump is damaged. Petrol is a poor lubricant in comparison to diesel fuel. Generally when this happens the entire fuel system needs to be flushed to remove the petrol and the metal debris from the damaged high pressure pump, then the pump and any other damaged components need to be changed.
Additional damage can also come from pre-detonation; diesel engines run far higher compression ratios than petrol engines, this is due to, in a simplified manner, diesel being less volatile than petrol. The effect is that the petrol/air mix may detonate 'early' i.e as the piston is rising during the compression phase, before the normal ignition and combustion phase. This essentially forces the piston to go back down early and attempts to turn the engine over in reverse. The huge additional forces generated can and almost certainly will be catastrophic for most internal components.
Given the huge potential for damage to your car's engine, it might be annoying but it makes sense to have the car towed or transported to a garage, to have the tank drained and then for the system to be checked through by a mechanic.
Going Technically,
In petrol engines the compression ratio used is around 10-12 (may vary according to model of car) and in diesel engines the compression ratio used is 20-22 (may vary according to model of car and manufacturer). So if diesel is put into a petrol engine the compression ratio of the engine is not sufficient for the burning of the fuel (diesel) so there is no power generated in the engine and also the spark that is induced in the petrol engine will not effect diesel hence at the end, during exhaust the fuel is let out (if exhaust stroke occurs)
Basically Power is not generated and the engine is clogged and you might have to remove all the parts for cleaning.
Gasoline in a Diesel vehicle will do some serious damage to the engine.
What happens is you must remove the petrol immediately. Petrol or gasoline will destroy a diesel engine.
petrol and diesel are fossil fuels so if you put fossil fuels in your car it should run
No.
Yes, petrol/gasoline will severely damage a diesel engine.
If you put petrol in a diesel vehicle do not start the engine. Petrol will do serious damage to a diesel engine. You must drain all the petrol out and flush the fuel lines.
Car will run poorly if at all.
Putting diesel into a car made to take regular gas is a very bad idea. Diesel can really mess up a car's fuel system, resulting in the need for expensive repairs.
Have it drained out and change filters
It will dirty the injectors a bit and run very rough,if at all. Still, not as bad as putting petrol into a diesel engine .
No,never. if ur going to try..............pls dont.
Who told you it is harmful? It is only harmful if it is a Diesel engine. If it is a petrol (gasoline) engine then Petrol is what it takes to run.
