How many types of engines are there?

[StCharlie]

There are many classification methods for automotive engines, and different types can be categorized based on different criteria. Below is relevant information: Classification by intake system: Automotive engines can be divided into naturally aspirated (non-turbocharged) engines and forced induction (turbocharged) engines based on whether the intake system uses a turbocharging method. Gasoline engines commonly use naturally aspirated systems; diesel engines often employ turbocharging to increase power. Classification by cylinder arrangement: Automotive engines can be categorized into inline and V-type based on different cylinder arrangements. In inline engines, all cylinders are arranged in a single row, usually vertically, but sometimes tilted or even horizontally to reduce height. V-type engines arrange the cylinders in two rows with an angle between them.
