What else can I help you with?
When air in the cylinder of a diesel engine is compressed it?
it gets hot, and ignites the diesel fuel that is injected by the fuel injectors.
What burns the fuel in cars?
The sparks plugs fire and ignite the fuel in a Gasoline engine, and compression compresses the fuel until it ignites in a Diesel engine.
What is different between gas and diesel engine?
diesal fuel ignites from pressure of the cylinder.gasoline ignites from the ignition spark from the distributor or coil pack.
How is a gasoline engine different from a diesel engine?
A gas engine ignites gasoline in the piston chamber with a spark from a spark plug. The expanding gas then pushes the piston out and the motor moves forward. A diesel engine uses diesel fuel, different from gasoline, and the fuel is compressed by the piston until it ignites, sending the piston out. There are no spark plugs in a a diesel engine. Some diesel engines will have "glow plugs" which are used to initially start the engine but once started, compressing the fuel is the method of ignition.
Why does diesel engine don't need an outside source of ignition?
The fuel ignites under high compression.
Why compression ratio of petrol enine is 8 where as diesel engine is 22?
because a diesel engine ignites its fuel with pressure, and not with a spark like a petrol engine. that is why a petrol engine does not need as high a compression ratio as a diesel engine
What type of internal combustion engine has no spark plugs?
The diesel engine, which ignites the fuel vapors by compression within a preheated cylinder.
Why does a diesel engine use a different type of fuel?
Diesel engines do not require "ignition" to burn diesel fuel--it is powered by the "heat of compression" therefore diesel fuel has a much higher "flash point" than gasoline. If you were to put gasoline in a diesel engine you would probably blow the heads off the engine. Due to lower "flash point" (temperature when fuel ignites). If you were to put diesel fuel in a gasoline powered engine, it would not ignite and engine will not start. Due to higher "flash point).
Why no spark plugs for diesel engine?
Because a diesel ignites due to the heat caused by the compression pressures in the diesel engine.
What causes ignition to occur in a diesel engine?
When the piston compresses the fuel-air mixture, the spark ignites it, causing combustion
Why is petrol not used in diesel engines or diesel in petrol engines?
Because the engines will not run with the wrong fuel to to their design. Although both diesel and petrol engines are internal combustion engines, they have differences that enable them to use these different fuels. A petrol engine ignites the fuel/air mixture by using a spark plug. A diesel engine in contrast has no spark but compresses air during the compression cycle. When air is compressed it heats up. Diesel is then injected into the cylinder and it ignites.
What causes diesel fuel to ignite?
Diesel fuel ignites due to a combination of high pressure and temperature in a diesel engine's combustion chamber. When the piston compresses the air, it raises the temperature to a point where the injected diesel fuel vapor ignites spontaneously without the need for a spark plug. This auto-ignition occurs because diesel fuel has a higher cetane number, allowing it to ignite more easily under the right conditions. Additionally, the heat generated from the compression process is critical for initiating combustion.
