In a diesel engine, this exhaust sometimes contains soot particles, which is why it is often black. This needs to be vented into the air, or the engine will crack from the pressure. Exhaust: When the fuel ignites, it creates fumes from the reaction.This creates the energy to cause the tractor to move. It is delivered in an even spray to the cylinders, where it ignites immediately. Ignition: The diesel fuel is injected into the cylinders by the injection rod.Compression: The air in the cylinders needs to be compressed and heated to a point that is so hot, that when the fuel is introduced to the air, it will ignite immediately.Inside the cylinders is where the combustion occurs. Intake: This is where the air is first allowed to enter the cylinders.The diesel fuel of a diesel engine actually lights on fire inside the engine to create the energy needed to propel your tractor. That means that it creates a force by igniting fuel internally.
