a. Four Stroke Cycle
b. Two Stroke Cycle a. Four Stroke Engine
- Expansion stroke by together valves closed, and lastly.
- Exhaust stroke in which the pistons move about with the exhaust valve open and so effecting the cycle and the cylinder wall are cooled by flow a cooling average during the cylinder cover or by slot in fins cooled by air.
- 1. Intake stroke anywhere the piston move by the intake valve unlock and the exhaust valve lock such that a mixture of air by atomized and vaporized fuel is use into the cylinder.
- Compression stroke, in which the air/fuel combination is compressed by both valves blocked chase by ignition of the airy fuel accuse by a timed spark.
- Two Stroke Engine have so limited function such as in little boat engines, lawnmower engines, the low cost and weight are more main than competence.
- This improvement, though, is equalizing by the beating of a portion of the intake charge by the exhaust gases, resultant in lower efficiencies.
- Intake and Exhaust strokes are reducing by use pre-compressed intake accuse to move the exhaust gases.
- Two Stroke Engine have the benefit of a high power to weight percentage.
