"D" None of the above
Thanks En.Alex..
"D" none of the above.
D none of the above.
I realize you are looking for the answer D... been asking in previous questions about the SI system and thermodynamic related questions;
However SI engine stands for Spark Ignition Engine and actually it can be all of the above, depending for what fuel the motor/engine is laid out for
I found following at Wikipedia
If the combustion of the fuel-air mixture takes place with the help of spark plug then it is known as four strokes Spark Ignition Engine. The SI engine operates at a ...
The term spark-ignition engine refers to internal combustion engines, usually petrol engines, where the combustion process of the air-fuel mixture is ignited by a spark from a spark plug. This is in contrast to compression-ignition engines, typically diesel engines, where the heat generated from compression is enough to initiate the combustion process, without needing any external spark.
Spark-ignition engines are commonly referred to as "gasoline engines" in America, and "petrol engines" in Britain and the rest of the world. However, these terms are not preferred, since spark-ignition engines can (and increasingly are) run on fuels other than petrol/gasoline, such as autogas (LPG), methanol, ethanol, bioethanol, compressed natural gas (CNG), hydrogen, and (in drag racing) nitromethane.
SI Stands for Spark Ignition, And this type of Ignition occurs In Internal Combustion Engine which are fuelled with Petrol or Gas.For Spark Ignition a Spark Plug is provided in the engine combustion chamber, and in the diesel engine Ignition is occurred by compression of air, so it is called Compression Ignition Engine (CI).
So for that Question Answer is
B)-Petrol Engine,C)-Gas Engine
