Disel fuel, like all oils, isn't compressible. Diesel engines relies on compression for ignition.
A standard 20 to 1 otto cycle is used for the petrol and diesel cycles for diesel engines. It is higher than gasoline engines due to the way diesels burn and compress fuel.
Diesel, being a liquid, is non-compressible, and since a diesel engine needs to compress air for (adiabatic) ignition, it won't be able to compress it, so it will jam the engine. Unlike gasoline, it will take a long time for the diesel inside to evaporate, so the vehicle is stuck until you fix it. This can be remedied on most diesel engines by arduously loosening or removing the injectors and then draining by suction or by cranking the engine until enough is squirted out to allow the engine to turn over.
Diesel fuel is heavier and oilier than unleaded fuel, which is lighter and more volatile. Diesel engines compress air to ignite the fuel, while unleaded fuel is ignited by a spark plug in gasoline engines. Diesel fuel is more energy-dense and efficient, but unleaded fuel produces fewer emissions.
The Diesel cycle engine was named after the German engineer who invented it, Rudolf Diesel. A Diesel engine uses two principles: air gets hot when you compress it, and fuel will ignite if it gets hot enough. The engine compresses air introduced into the cylinder to a very high pressure. When fuel is injected it immediately ignites.
The prefix of "compress" is "com-".
you have spelt it correctly
diesel engines compress the fuel mixture much more than gasoline engines, diesel engines are always fuel injected while gasoline engines have the option of being carbureted, diesel engines usually cost more, diesels produce more power than a comparable gasoline engine, diesel engines have no distributor or spark system, and instead use glow plugs to ignite fuel, and diesel engines can be converted to run on vegetable oil with few modifications.
Pressure. Anything you compress increases pressure you ignoramus. Also, what you 'asked' wasnt even a properly worded question. Go back to school.
compress it nearly impossiable to COMPRESS solids and liquids
CNG engines create less polution than petrol and diesel engines.As it is using compress natural gas power develops more than the others and also develops more torque in the engine.which leads to give a lower fuel consumption.
Compress. They tend to occupy a nearly fixed volume.
Probably not: Knoking is the combustion of the fuel mixture before the actual ignition took place. This self-combustion is most commonly caused by high revving of the engine: the mixture becomes so hot due to rapid compression it ignites without a spark. Diesel engines don't compress a air-fuel mixture, but only compress air. The fuel is injected when the piston is at top position (approximately), and ignites at that very moment; the compressed air is hot enough to cause ignition. The timing of ignition in a diesel engine is therefore correct, also if you compress the air much more than with a petrol engine. This is in fact what is done, (compression ratio diesel is much higher than petrol, this fact makes this possible). This higher compression ratio gives a higher efficiency; as you'll probably know diesels are more fuel efficient.
