Dieseling (in the sense of engine run-on, and disregarding combustible gaseous mixtures via the air intake) can also occur in diesel engines, when the piston or seals fail due to overheating, admitting engine oil into the cylinder. A structurally failing diesel engine will often accelerate when the throttle is released, even after fuel ...
Crankcase dilution occurs when the fuel oil from the engine gets into the lube oil of the engine. This can be caused by the walls being wetted due to the fuel condensing in the cylinder. If the engine is cold, or there is an excess amount of cooling around the cylinder, [ 1 ] the fuel oil will condense and have a higher chance to end up in the ...
It can be mistaken for lubricating oil in some cases, but it consists of the "heavy ends" of the diesel fuel which do not burn when combustion temperature is too low. The heavier, more oily components of diesel fuel contain more stored energy than a comparable quantity of gasoline, but diesel requires an adequate loading of the engine in order ...
A tank of diesel fuel on a truck. Diesel fuel, also called diesel oil, heavy oil (historically) or simply diesel, is any liquid fuel specifically designed for use in a diesel engine, a type of internal combustion engine in which fuel ignition takes place without a spark as a result of compression of the inlet air and then injection of fuel.
That can never hurt your engine, but it also means they'll see you and your credit card more often. When your car's on the lift for an oil change, other wear items such as brake pads, coolant ...
Diesel engines can combust a large variety of fuels, including many sorts of oil, petrol, [4] and combustible gases. [5] This means that if there is any type of leak or malfunction that increases the amount of oil or fuel unintentionally entering the combustion chamber, the quality of the air-fuel-mixture will increase, causing torque and ...
This is often known as a "money shift" because of the likelihood of engine damage and the expense of fixing the engine. Redlining in a diesel engine can be caused by the engine receiving fuel from an unintended source, such as flammable vapour in the intake air, or a broken oil seal in a turbocharger. This is known as diesel engine runaway, and ...
Low temperatures cause engine oil to become more viscous, making it more difficult to circulate the oil. Air becomes more dense the cooler it is. This affects the air-fuel ratio, which in turn affects the flammability of the mixture. Fuel becomes thicker because the paraffin wax in the fuel is thicker at low temperatures (most common in diesel ...
