How a gas engine works?

Question

principles of operation of a gas engine

Answer 1

Internal Combustion reciprocating engine

Piston goes down valves open take in air and fuel
Piston goes up valves close compresses air and fuel
spark plug fires forcing piston back down
Piston goes up valves open release exhaust
go back to the top and repeat

all of which must be timed perfectly
Basically thats it

Answer 2

I will try to explain a 4 cycle engine....It has Intake... Compression... Power...and Exhaust cycles. The engine comprises a cylinder, a piston and valves (intake and exhaust). And a spark plug to ignite the fuel. So lets take one particular cylinder.

The piston goes down with the intake valve open to suck in the air and fuel from the carburetor. Next the intake valve closes and the piston rises to compress the fuel mixture and then when it reaches the top the spark plug fires and pushes the piston down then it comes back up with the exhaust valve open to expel the burnt fuel.

The spark plug gets its spark from the coil which builds up a very high voltage which enables the spark to jump the gap of the electrodes of the plug.

The distributer is adjusted so that it distributes the spark at the right time to each of the pistons.

I hope this helps!!!!

Answer 3

Same as a petrol or gasoline engine, suck squeeze bang blow. Fixed engines running on coal gas were used in the 19th century and predated the petrol engine by about 10 years. Conversion of petrol engines to run on liquified petroleum gas or liquified natural gas is common. Converted cars usually keep their petrol tanks and can switch from one fuel to another while running.
