Near the end of the compression stroke in a compression ignition engine, the piston reaches the top dead center (TDC), and the air within the cylinder is at a high temperature and pressure. At this point, fuel is injected into the highly compressed and heated air, causing it to ignite spontaneously due to the high temperature. This ignition leads to a rapid increase in pressure, driving the piston down during the power stroke.
I think you have a typographical error in your question. The question I believe is "What is a compression ignition engine?" The answer is:- A diesel engine is a compression ignition engine.
Compression ignition is deisel. Otherwise, spark ignition is gasoline.
The lowest compression ratio of a compression-ignition engine that allows a specific fuel to be ignited by compression ignition.
A 'spark ignition ' engine is your regular gasoline engine as opposed to a diesel, which is a 'compression ignition' engine
compression ignition
Compression ignition engine.
Performance, horse power and fuel mileage will suffer.
Ignition is accomplished by compression.
the diesel engine. it takes one ignition to start, then it runs off of (autoignition) ignition from heat caused by high compression. compression ignition (autoignition) causes ignition to happen a little earlier than spark ignition engines (gas engines) which is less vulnerable to risk of engine knocking or wasted power when dealing with high compression. -maddmatt
During the compression stroke in an internal combustion engine, the piston moves upward, compressing the air-fuel mixture in the combustion chamber. This compression increases the pressure and temperature of the mixture, preparing it for ignition.
S.I Engine lower compression Ratio is 6 to 11
a diesel engine uses compression and has no need of spark plugs
