Question

Accepted Answer

Explanation of engine and its principle, piston work, and difference between two and four stroke engines.

An engine is a machine that converts fuel into mechanical energy.
The principle of an engine is based on the conversion of heat energy into mechanical energy.
Piston is a component of an engine that moves up and down in a cylinder.
In an engine, the piston compresses the fuel-air mixture, which is then ignited by a spark plug.
The difference between two-stroke and four-stroke engines is the number of strokes required to complete a cycle of operation.

Accepted Answer

1 consume fuels to performs mechanical works by exerting torques or linear force (usually in the form of thrust). Devices that convert heat energy to speed are usually referred to as engines only. Examples of engines that exert a torque include the familiar automobile gasoline and diesel engines, as well as turboshafts.

Examples of thrust-generating engines include turbofans and rockets. From reading the rest of that page, it seems that the term originally refers to any mechanical device that looks at any form of energy & converted it into useful mechanical motions. So something connected to an air or water mill, or even powered by humans or animals, would be called an engine.

It is interesting to me that the meaning of the term has changed, and it underscores the dramatic significance of the invention.

Princple of engine :-

The engine then partially converts the energy from the combustion to work. 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.

Piston work in engine

As a component of combustion engines, the piston converts the energy released during combustion into a mechanical action and transfers it to the crankshaft in the form of a torsional force via the piston pin and the connecting rod. When the engine is running, the piston moves up and down in the cylinder.

Difference between two stroke and four stroke

The main difference between a 4-stroke engine and a 2-stroke engine is that a 4-stroke engine goes through four stages, or two complete revolutions, to complete one power stroke, while a 2-stroke engine goes through 2 stages, or one complete revolution, to complete one power stroke
