Diesel Injection Engines

Diesel engines work much differently to petrol engines that they use a method of direct injection where the diesel is injected into a special cylinder which in turn then controls the compressed air. So, this compression then helps to self ignite.​ This then turns the pistons and drives the engine.

What Happens When You Put Petrol in a Diesel Engine

Now, if you put petrol into a diesel engine then this can have big repercussions if left untreated. Generally speaking if you add a small amount of petrol to your tank then you'll be more than fine, but left untreated with large amounts of petrol a diesel engine can cause long term damage as the petrol will begin to act as a solvent and the metal to metal contact will create small particles of metal that can run through the engine and start to erode parts.
