Which type of ic engine

Question

Accepted Answer

Internal combustion engines are classified into two main types: spark ignition (SI) engines and compression ignition (CI) engines.

Spark ignition (SI) engines use a spark plug to ignite the fuel-air mixture, commonly found in gasoline engines.
Compression ignition (CI) engines rely on the heat generated by compressing the air in the cylinder to ignite the fuel, commonly found in diesel engines.
Each type of engine has its own advantages and disadvantages based on factors such as fuel efficiency, power output, and emissions.
Hybrid engines combine elements of both SI and CI engines to optimize performance and efficiency.
Alternative fuel engines, such as electric or hydrogen-powered engines, are becoming more popular due to environmental concerns.
