Company and work details

Q1. What is the working principle of a four-stroke engine?
Ans. 
A four-stroke engine operates through four distinct strokes: intake, compression, power, and exhaust, converting fuel into mechanical energy.
• Intake Stroke: The engine draws in a mixture of air and fuel as the piston moves down, creating a vacuum.

• Compression Stroke: The piston moves up, compressing the air-fuel mixture, which increases its temperature and pressure.

• Power Stroke: A spark ignites the compressed mixture, ca...read more
