What happens when you put diesel fuel in gasoline engines?

Answer 1

It fouls the plugs, the engine blows out a bunch of smoke and then quits running.

Answer 2

Because gasoline cars work with around 40psi of fuel pressure Some Diesel engines work at thousands of psi of fuel pressure. Hence a gasoline engine will fill up with alot of fuel fast and since Diesel is full of impurities is much harder to ignite than gasoline, so it will burn in your engine rather then igniting, since diesel has additives to keep the fuel from jelling up this additives burn when the spark plugs work and leave a sludge substance in the pistons untill the valve intake and exhaust system can no longer perform, and then the spark plugs get sludged and the vihicle can no longer work. Keep in mind this happens fairly quick, lots of smoke will be created, if the fuel is pressed down fully the car will stall.

this link is about the system on a specific vehicle but has data that can help you understand more about how a diesel engine works (mainly the components required) and you can later find more info about gasoline engines and compare.

Answer 3

Trying to use diesel fuel in a gasoline engine has unpleasant consequences, but generally not as dire in terms of damage to the fuel system. Depending on the proportion of diesel fuel relative to gas in the tank, a gasoline engine will either run poorly or stop altogether, necessitating a $500 trip to the repair shop for draining and flushing. A couple of old grease monkeys at the shop I used to work at claimed that their "super high-compression" gasoline engines of the late 1960s could easily switch between gasoline and diesel fuel with no problems, but I tend to think they spent too much time inhaling fumes from the carburetor cleaning tank

Answer 4

I did that once. The car was virtually obscured by the smoke--I mean a LOT of smoke. I had to have the gas tank removed and cleaned out. What else the mechanic did, if anything, I don't remember.
It was really dramatic to see. Don't do it. I doubt the car ran with diesel in it, nor could anyone have tolerated the smoke enough to get in.

Answer 5

Diesel fuel is basically a heavy oil.

You'll get a lot of smoke, it will clog your fuel filter and if it gets past your filter it will clog the injectors. It could damage your fuel pump and your catalytic converter and gum up your spark plugs.

Answer 6

lots and lots of smoke
sparkplugs fouled
and possible fuel filter cloging
