Why does a diesel engine develop more torque than a gasoline engine of equivalent displacement?
Diesel engine runs at a higher compression ratio than a gasoline engine. A typical diesel engine may also use a longer stroke and smaller bore than a gasoline engine. Diesel fuel has a higher energy density than gasoline.
Where was diesel found in the world?
Diesel oil is a fraction of petroleum. It ignites easier than gasoline, on just compression heating without needing a spark.
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.
How much gasoline can be added to a diesel auto's fuel tank without causing problems. I've heard the ratio can be as high as 70 percent diesel and 30 percent gasoline?
Incorrect on both accounts. The distillates in diesel are different than gasoline, in that they have different ignition points and cetane ratings. Because of this, adding gasoline to diesel will inhibit the ignition in the diesel engine, just as adding diesel to a gasoline engine will cause the fuel to ignite too quickly. In general, never mix the two. You can add diesel-specific additives to diesel, but gasoline is never recommended. More info: http://www.turbodieselregister.com/mixing_gasoline_and_diesel.htm
What is petroleum energy?
Petroleum energy is energy derived from petroleum products: gasoline, diesel fuel, heating oil, etc.
What fuels can be made out of crude oil?
Gasoline, jet fuel, kerosene, diesel for cars, and heating oil are the most common.
Are diesel cars more efficient than normal cars?
Because of a diesel engines high compression ratio, it will always be more efficient than an equivalent gasoline engine. However, this higher compression ratio requires a heavier, more expensive engine which isn't able to reach as high an RPM as a gasoline engine. It is for these reasons that despite their higher efficiencies, diesel engines are less popular than their lighter, less expensive gasoline equivalents. Diesel cars will provide you with a higher MPG rating compared to a similar gasoline powered engine. The price for diesel fuel is generally higher than the cost of unleaded gasoline.
What are some of the fuels we use - extracted from crude oil?
Gasoline (petrol) Paraffin Diesel (DERV) Gas oil (Heating oil)
2008 ford diesel unleaded fuel in tank?
Diesel engines have a much higher compression ratio than gasoline engines. Therefore, you need to drain all the gas you can out of you tank and fill it with diesel.
Does diesel engines run on diesel fuel or gasoline fuel?
Diesel engines run on diesel fuel. Gasoline will destroy a diesel engine.
Why the cars which run on petrol cant be run with diesel?
Petrol engines use a spark plug to ignite the gasoline. Diesels on the other hand use compression to ignite the fuel. Diesel engines have a very high compression ratio that causes the fuel to ignite under pressure. Gasoline engine do not run near the compression as a diesel. Put diesel in a gasoline engine and it simply will not run. Reason being is that diesel fuel has a much higher flash point. Gasoline contains 4 to 12 carbon atoms, diesel has 10 to 20 carbon atoms and is much heavier than gasoline.
Does a diesel engine require more oxygen than a gasoline engine?
Yes a diesel engine requires a lot more air than a gasoline. The ratio for air to fuel in a gas engine is about 14.7:1. A diesel at idle is about 50:1 and in the higher rpms it can reach 70:1.
