The Spark Ignition (SI) engine can be compared with the Compression Ignition (CI) system in 7 aspects. These 7 aspects are engine speed, cycle efficiency, fuel used, time of knocking, cycle operation, the pressure generated and constant parameters during the cycle. …

The below table can be read like the table of comparison between the two types of engines and also as the merits and demerits of the two designs. 4-Stroke and a 2-Stroke Engine comparison S.no 4-Stroke Engine 2-Stroke Engine 1 One working stroke for ev…

Honda developed VTEC (Variable Timing and Lift Electronic Control) to improve the volumetric efficiency of a four-stroke internal combustion engine . Ikuo Kajitani, engineer at Honda was the first involved in the development of these four-valve engines. The Honda’s VTE…

In an air-cooling system, the outer surface of the cylinder and the cylindrical head in a reciprocating engine are cooled by air flowing over them. To increase the heat transfer rate from the surface, the metallic fins are cast on the cylinder and cylinder head. These …

The following are the factors that influence the compressed ignition (CI) engine cycle: Non-constant pressure combustion of the fuel Dissociation Blow-down losses Pumping losses 1. Non-constant pressure combustion of the fuel: In the basic…

In a liquid-cooling system , water or other solutions flow through the water jacket around the cylinder and cylinder head to absorb the heat. The hot liquid from the water jacket is cooled in the radiator, where circulated air absorbs the heat from the radiator. The co…

The internal combustion engine is an engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high temperatu…
