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 for the same power CI engines are larger and heavier than SI engines?
SI is SPARK IGNITION - Otto (4-stroke) and Day (2-stroke) cycle CI is COMPRESSION IGNITION (DIESEL) also in 4- and 2-stroke variants The SI spark plug is timed to start combustion at the ideal moment, usually some degrees before the piston reaches the top (TDC or Top Dead Centre). The burning mixture then drives the piston down for the power stroke. The CI fuel is injected (sprayed) into the cylinder at the ideal moment - this too is usually some degrees before TDC, and the red-hot air in there then starts the fuel burning. This then drives the piston down for the power stroke. SI is limited in maximum compression ratio (the amount the air or mixture is compressed as the piston rises in the cylinder), or it can start to behave like CI (Dieselling). CI uses the highest compression ratio possible to improve ignition - and - improve efficiency too... The expansion ratio is the inverse of the compression ratio, and the more that the burning gas is allowed to expand whilst doing work, the better the efficiency. CI is also an 'excess air' cycle, potentially. A full cylinder of air is compressed each time, and the amount of fuel injected is varied to change power - this is beyond the lean burn that can be achieved with SI.
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)

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 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.
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.
How many types of 351 ci engines are there?
Early Ford made 3 351 ci motors. 351 cleveland, 351 windsor and 351 M for modified.
What is OPSEC definition of CI?
In an OPSEC context, CI (Counterintelligence) refers to activities conducted to protect against espionage, sabotage, or other intelligence activities conducted by foreign entities or adversaries. It involves identifying, assessing, and neutralizing threats to safeguard sensitive information and maintain operational security.
What engines will fit in a 1977 Chevrolet caprice classic?
267 ci 305 ci 327 ci 350 ci 400 small block and big block ci 454 big block simply any engine made by cheverolet make sure you get the right transmission, drive shaft, and rear end
How much horse power does a 2002 2.2 cavalier have?
they have a 134 ci. engines and 110 stock hp
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)
