Difference between ignition temperature and self ignition temperature?
The air temperature in a diesel engine cylinder is 1022 F. This will ignite the fuel. the high compression, 22 to1, will light the fuel. A spark engine with a carburetor may "diesel" when the key is turned off because of glowing carbon deposits in the cylinder, self ignition.
In a diesel engine the airfuel mixture is ignited by?
it is ignited due to the high temperature caused by the pressure inside cylinder, when it is compressed.
Why not diesel engine is spark ignited?
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.
What does Mercedes E 320 CDI is it petrol or diesel?
This engine is an inline 6 cylinder diesel engine. It runs on Diesel.
Why during the ignition pressure remain constant in diesel engine?
The ignition temperature, (temperature at which diesel fuel ignites) is 490*F. This temperature corresponds to a set compression of the gasses in the cylinder of the engine. Some, but not all, diesel engines have glow plugs to initially warm the air when you first start the engine because the temperature of the air in the diesel engine is too cold to get the ignition temperature simply from compression. while the engine is running the compression heats the air to the ignition temperature. This compression (or pressure) is the same each time the cylinder fires. Using the universal gas law you can find that corresponding compression versus the ambient temperature and pressure. Typically this will occur at approximately 16 bars. Almost all diesel engines are designed to operate at a compression ratio of 15:1 - 20:1, less if supercharged or turbocharged.
What is the purpose of a cylinder head on a diesel engine?
The purpose of the cylinder head is Luke Cooper
What is the firing order of a six cylinder diesel engine?
153624
Can you replace a Dodge Ram 6 cylinder engine with a Dodge Ram diesel engine?
it depends on the size of the diesel engine going in so yes and no
What are the different types of piston engine according to cylinder head classification?
diesel engine
Does a 1996 dodge 2500 4x4 diesel come in a 6-cylinder or 8-cylinder?
Any Dodge diesel to date features and inline, six cylinder Cummins engine.
What is so good about diesel engines?
The diesel engine works by compressing the fuel and air mixture inside a piston cylinder. Compressing the mixtures raises its temperature. When the temperature reaches the fuels ignition point, it ignites, explodes and pushes the cylinder back.A gasoline engine works similarly but needs a high voltage spark from an ignition system to ignite the fuel.What is good about the diesel engine:The diesel engine does not need a complex electrical system to keep the engine running.Diesel powered vehicles do use a battery to start the engine turning, once the engine starts it is no longer needed.A diesel engine does not need spark plugs and distributor system to keep running although it does use glow plugs to help it start when the engine is too cold.Diesel engine fuel is cheaper to use than gasoline (petrol). Some people even use home heating oil to power a diesel engine (after passing it through a filter to remove sediment).A diesel engine has a higher compression ratio in the cylinder making it more efficient than a gasoline powered engine.
Can you use petrol for 4 cylinder 4 stroke diesel engine?
No.
