Engine technology refers to the design and development of engines that convert fuel into mechanical energy. This technology is crucial for various applications, including vehicles, aircraft, and industrial machinery. Different types of engines, such as internal combustion engines and electric motors, utilize distinct principles to generate power. Advancements in engine technology focus on improving efficiency, reducing emissions, and enhancing performance. Innovations like hybrid engines combine traditional fuel sources with electric power, while turbocharging increases engine output without significantly increasing size. These developments aim to meet growing environmental standards and consumer demands for better fuel economy.
