What is so good about diesel engines?

Best Answer

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.

Are diesel engines more polluted than steam engines?

Of an individual diesel engine and an individual steam engine of the same energy output the diesel engine would be less polluting. It is far more efficient. However, there are far more diesel engines than steam engines in the world today so overall diesel engines pollute more than steam engines.


Why do diesel engines require more maintenance?

They dont, diesel engines are generally more reliable than gas engines, and alot simpler due to the fact that the entire ignition system found in gas-powered engines is deleted entirely from the diesel equation. (Diesel engines don't have spark plugs, they rely on compression to ignite the fuel, meaning: they sqeeze the diesel fuel so much that it explodes)

Does a double decker bus use petrol or diesel?

Well this all depends on what type of engines are supplied in these buses. Usually buses use diesel due to the high weight load that that are put on the engines. Diesel engines have better compression and can usually provide more torque to do work with all those people on board. Here is a good read on Diesel engines....(link)

What problems did the diesel engine have?

1. Diesel engines, because they have much higher compression ratios (20:1 for a typical diesel vs. 8:1 for a typical gasoline engine), must have thicker metal castings so tend to be heavier than an equivalent gasoline engine.2. Diesel engines also tend to be more expensive to buy. However, because diesels can do more miles per gallon, they are well worth the extra money because, but, if you do a big annual mileage, they will save you money buying diesel fuel instead of gasoline.3. Diesel engines, because of their weight and compression ratio, tend to have lower maximum RPM ranges than gasoline engines. This makes diesel engines high torque rather than high horsepower, and that tends to make diesel cars slower in terms of acceleration. The latest designs of diesel engine have performances which are almost as good as as gasoline engines.4. Diesel engines must be fuel injected, and in the past fuel injection was expensive and less reliable. Nowadays many gasoline engines also use fuel injection systems and the designs of both the injector fuel pumps - and the injectors themselves - have been improved to make them very reliable.5. Diesel engines tend to produce more smoke and "smell funny." Nowadays, provided they are serviced correctly, diesel engines don't emit more smoke.6. Diesel engines are harder to start in cold weather, and if they contain glow plugs, diesel engines can require you to wait before starting the engine so the glow plugs can heat up. Modern diesel engines don't have that problem.7. Diesel engines used to be much noisier and tended to vibrate. Modern diesel engines can be almost as quiet as gasoline engines and they don't vibrate so much.8. In some places diesel fuel is less readily available than gasoline.

Diesel engines do not engine brake like gasoline engines do, so relatively speaking, the rate of deceleration would seem to be slower.
