Want this question answered?
it is ignited due to the high temperature caused by the pressure inside cylinder, when it is compressed.
petrol engine - Fuel and air mixtures together and compressed in engine. These mixtures ignited by Spark plug Diesel Engine - Air only compressed at high pressure and Temperature. Fuel injected at high temp so that the ignition takes place
Just due to the heat of Compression. The fuel is Injected at a point where the air temp is high enough the fuel burns.
Answer this question… What is injected into high pressure air
HDI is High pressure Direct Injection engine that is found in diesel cars. Fuel is injected into the combustion changer under high pressure.
Jet fuel is injected into high pressure air in jet engines.
A gasoline injects fuel into the cylinder as it is filled with air, compresses it, then ignites the spark plug to trigger the power stroke. In a diesel engine air is compressed up to 3 times more causing a much higher cylinder temp. Once the air in the cylinder is hot diesel fuel is injected directly into the cylinder and is ignited by the high temperature.
Well gasoline engines have a spark plug that ignites the gasoline as it is injected into the engine. Diesel engines have no spark plugs because the high compression ignites the fuel as it is injected. Because it releases higher energy density, diesels get better fuel economy.The main difference between a diesel and a gasoline (petrol) engine are the way the fuel is ignited. In a gasoline engine, a fuel/air mixture is introduced into the cylinder either through a carburetor or fuel injection system, where it is then compressed and ignited with a spark. In a diesel engine, air is compressed in the cylinder which heats it to about 1000 degrees F (550 degrees C), then fuel is injected under high pressure and ignited by the superheated air. To accomplish this, diesel engines also have higher compression ratios than gasoline engines.
symptoms of high engine oil pressure
No, on a fuel injected engine it can cause high idle speed.
high oil pressure usually means that a liner in the engine cylander has dropped. take it to a mechanic
if its not fuel injected then check on the side of engine block follow fuel lines from tank or from carburetor if its fuel injected then there are two electric fuel pumps one in the tank and one on the inside of frame rail on driver side the one in tank is a low pressure pump and the one on frame rail is high pressure fuel pump
