Comparative Factors in Spark Ignition (SI) and Compression Ignition (CI) Engines for a Sustainable Technological Economy

This article titled Comparative factors in spark ignition and compression ignition engines for sustainable technological economy, compares the differences between the both types of internal combustion engines, with respect to their working principles. The spark ignition (SI) engines, uses petrol or gasoline as fuel, while in compression ignition (CI) engines, diesel is used as fuel. Petrol engines are lightweight and achieve higher speed while diesel engines, on the other hand, are heavy engines and achieve lesser speeds. The most prominent difference between Spark Ignition (SI) and Compression Ignition (CI) engines is the type of fuel used and the process of mixing the fuel for effective combustion. The spark ignition engine uses carburetor as a means of mixing the air and fuel in equal proportion while compression engines uses injector.
