SI engine means Spark Ignition Engine where combustion products(air,fuel)are ignited in combustion chamber by means of spark from spark plug which is located on cylinder head..
CI engine means Compression Ignition Engine,here combustion is take place by means of compression..

Why si engines are quantity governed engines and ci engines are quality govrned?
All engine are whether CI or SI are quantity governed. what is quality governed?? You have discovered it or wht??
Why CI engines are used in trucks and other heavy vehicles but not why SI engine?
Compression ignition (CI) engines use diesel is as the fuel, while spark ignition (SI) engines use petrol. SI engines are lightweight and achieve high speeds while diesel CI engines although heavier and slower engines, are more robust and have a higher thermal efficiency. Their robust build (and fewer parts) makes diesel CI engines ideal for heavy machinery.
What is SI engine and CI engine?
An SI engine is a spark ignition engine. A CI engine is a compression ignition engine. SI engines use spark plugs to ignite fuel in the combustion chamber. CI engines use compression in the combustion chamber to ignite the fuel.
What will happen if SI engines is used in place of CI engines in trucks?
we can use si engines in place of ci engine in trucks.. Bt as u know in trucks heavy power is required to carry such high loads.. Nd also the cost of petrol is higher than diesel so to obtain high mechanical power nd less running cost diesel engines are used..!
Why can CI engines be more easily pressure charged compared to SI engines without fear of detonation?
because it only compresses/pressurized air (without the mixture of fuel)
Where is fuel and air mixed in an engine on a newer car?
Mixing of fuel and air depends on type of the engine whether SI or CI. In carburetted versions of SI engines the charge mixes in the carburetion chamber and the mixture is let into the engine. There are direct injection SI engines(GDI) where the injection takes places at various stages of charge compression stroke. In CI engines the fuel is mixed with air in the combustion chamber itself. It is to be borne in mind that these mixing phenomenon are the same be it a new or old car.
What is the difference between a SI engine and a CI engine?
An SI engine ignites the fuel with a spark (SI = Spark Ignition) whereas the CI engine ignites the fuel with heat generated from compression (CI = compression ignition)
What is the ci engines?
compression ignition
What are stages of combustion in CI engines?
Intake, compression, power/combustion, exhaust. Same as a standard SI (Spark Ignition) CI (Combustion Ignition) is how diesel operates. They contain no spark plugs. The compression heats the fuel to the point of SELF COMBUSTION .
Why can a CI engine be more easily pressure charged compared to SI engines without fear of detonation?
because it only compresses/pressurized air (without the mixture of fuel)
What size engines came in the 1981-1982 Chevy C10 pickup trucks?
250 ci,305 ci, 350 ci, 350 ci (Diesel), 379 ci (Diesel) (1982).
Whats the meaning of CI in Ci engines?
The CI stands for compression-ignition engine also known as a diesel engine. The CI engine is classified as an internal combustion engine.
