The most prominent difference between Spark Ignition (SI) and Compression Ignition (CI) engines is the type of fuel used in each. In SI engines petrol or gasoline is used as fuel, hence these engines are also called petrol engines. In CI engines diesel is used as fuel, hence they are also called diesel engines.
9) The petrol engines are also known as
Answer is:
Spark ignition (S.I) engines

Answer is:
Diesel cycle
Explanation:
The Diesel cycle is a combustion process of a reciprocating internal combustion engine. In it, fuel is ignited by heat generated during the compression of air in the combustion chamber, into which fuel is then injected.
A Diesel cycle consists of one constant pressure, one constant volume and two isentropic processes.
Answer is:
Compression ignition (C.I) engines
Explanation:
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to the mechanical compression. Hence diesel engines are also called as Compression ignition (C.I) engines.
Answer is:
Diesel cycle is more efficient than Otto cycle
Explanation:
For the same maximum pressure and temperature Diesel cycle is more efficient than Otto cycle.
Answer is:
the heat of compression
Explanation:
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to the mechanical compression. Hence diesel engines are also called as Compression ignition (C.I) engines.
