Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is a gas engine?A gas engine is a machine that makes work by burning gas inside a cylinder. It turns the energy from the gas into motion or electricity.
2. How does a gas engine use gas to make things move?The engine mixes gas with air, then ignites it so the gas expands and pushes a piston. The moving piston turns a crank that can drive machines or generate power.

Internal Combustion: A process where fuel is burned inside the engine to produce mechanical work.
Biogas Production: The generation of methane and carbon dioxide from the anaerobic decomposition of organic matter.
Four-Stroke Cycle: The sequence of piston movements (intake, compression, power, exhaust) that completes one operating cycle.
Peak Load Shaving: Using on-site generators to supply power during periods of highest electricity demand, reducing costs.
