Four Stroke Cycle – Otto Cycle

Starting position, intake stroke, and compression stroke.

Ignition of fuel, power stroke, and exhaust stroke.

Four Stroke Cycle – Diesel Cycle

Two Stroke Cycle – Otto Cycle

Comparison of 4 - stroke & 2 - stroke Engines To produce same power 2 stroke cycle engine will be of less weight and space To produce same power 2 stroke cycle engine will be of less weight and space More uniform turning moment in 2 stroke cycle engine More uniform turning moment in 2 stroke cycle engine Since no valve in 2 stroke cycle engine more mechanical efficiency, simple construction, low initial cost, power saving… Since no valve in 2 stroke cycle engine more mechanical efficiency, simple construction, low initial cost, power saving… Fuel consumption is increased in 2 stroke cycle engine Fuel consumption is increased in 2 stroke cycle engine

Comparison of 4 - stroke & 2 - stroke Engines Two-stroke engines don't last nearly as long as four-stroke engines due to the lack of a dedicated lubrication system. Two-stroke engines don't last nearly as long as four-stroke engines due to the lack of a dedicated lubrication system. Two-stroke engines produce a lot of pollution due to the combustion of the oil and due to the fact that each time a new charge of air/fuel is loaded into the combustion chamber, part of it leaks out through the exhaust port.
