What do you know about engine?

Question

Accepted Answer

An engine is a machine that converts energy into mechanical force and motion.

Engines are used in various applications such as automobiles, aircraft, and power plants.
They typically work by burning fuel to create combustion, which generates energy.
Engines can be classified into different types, such as internal combustion engines and external combustion engines.
Internal combustion engines, like those found in cars, use fuel combustion within the engine itself.
External combustion engines, like steam engines, use an external heat source to generate steam and produce mechanical work.
Engines have various components, including cylinders, pistons, valves, and a crankshaft.
They require lubrication and cooling systems to operate efficiently.
Engine efficiency is measured by factors like fuel consumption, power output, and emissions.
Advancements in engine technology have led to improved efficiency and reduced environmental impact.

Accepted Answer

The engine consists of a fixed cylinder and a moving piston.

The expanding combustion gases push the piston which in turn rotates the crankshaft.

Ultimately, through a system of gears in the powertrain, this motion drives the vehicle's wheels.
