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 happens if you put unleaded gasoline in a diesel car?
Diesel engines have a much higher compression ratio than gasoline engines. Therefore, you need to drain all the fuel you can out of your tank and fill it with diesel. Gas in a diesel engine will go boom, and destroy your engine.
Why is your Diesel engine smoking?
My diesel engine is not smoking. If your's is smoking there can be a variety of reasons, you would need to be more specific in your question
How much compression should a diesel have?
A diesel engine requires at least a 20:1 compression ratio, or about double a gasoline engine. The PSI this translates to depends on the size of the cylinder. You will need to consult the manufacturer's service manual.
How do you build a diesel hovercar?
well you need a powerful diesel engine to make the air to hover. and the rest YOU need to come up with. a V8 turbo diesel or a V10 turbo diesel should be more than enough.
Why do diesel vehicles need to be kept running?
A diesel vehicles does not need to be running. A diesel ignition in a Diesel engine comes from compression and not spark.
Did the diesel engine save people money on gas?
The diesel engine saves a number of people a lot of money on fuel. A diesel is far more efficient. Its problem is that it is not as responsive to the accellerator. Still, locomotives or long haul trucks do not usually need tremendous accelleration. They generally need steady speed. They need distance on the least amount of fuel. For them, the diesel is far better than the otto engine.
What engine oil do you need for a 306 diesel?
any diesel oil will be fine
Why is Diesel engine hard to start?
Diesel engines have a much higher compression ratio than a petrol engine, meaning that they compress a larger volume of air into, for arguments sake, the same space as a comparitive petrol. This requires more torque to turn the engine over but results in a bigger bang. Which is why they are hard to start as they need a bigger electric motor to start them and are almost imposible to clutch start
Batteries on diesel car bigger than that of gasoline car?
Yes, a diesel may require more cranking power with cold weather. The difference between gasoline and diesel engine is compression ratio. For standard gasoline engines it is between 7:1 to 10:1. It means that when piston is in Bottom Dead Center the volume inside cylinder liner closed by piston and cylinder cover is 7-10 times biger than the same volume when piston is in Top Dead Center. For Diesel engines compression ratio is around 16:1 to 22:1. If you take a hand pump for bike tires and compress it to only half stroke and compare this with full stroke, you will see the difference between force you have to use. At car electric motor is used for cranking cars engine. For rotating diesel engine you need electric motor with more torqe/power. For more torqe/power you need more electrical current. For mor electrical current at start you need bigger battery.
How can you convert petrol engine in into diesel engine?
You can convert a petrol engine into a diesel engine by changing the fuel injectors. The fuel filters will also need to be changed.
How can calculate power of diesel Engine?
You will need to have some information ready. It is good to know the horsepower and the torque of your diesel engine.
