[ig′zȯst ‚strōk]
(mechanical engineering)
The stroke of an engine, pump, or compressor that expels the fluid from the cylinder.

Exhaust stroke.
The fourth stroke in a reciprocating engine in which the piston is moving away from the crankshaft and the exhaust valve is open to permit expulsion of burned gases.

As the residual swirl of the flow in the cylinder at the end of the exhaust stroke was not taken into account, the flow was supposed to be quiescent initially.
During exhaust stroke, piston moves up the cylinder bore, decreasing the total chamber volume.
For example, at the start of the intake stroke of cylinder one and when both the intake and exhaust valves of cylinder one are open (valve overlap period), cylinder three already starts its exhaust stroke with the exhaust valve open.
Previously unburned fuel is oxidized before the exhaust stroke, substantially reducing carbon soot emissions, keeping the engine cleaner and lowering NOx emissions per vehicle mile traveled as a result of increased fuel efficiency.
Due to incomplete combustion of injected fuel and part of the combustion extending into the exhaust stroke, there is a slight increase in exhaust gas temperature with biodiesel compared to diesel.
By reopening the intake valves during the exhaust stroke, emissions are reduced - up to 40 percent for hydrocarbons and carbon dioxide to up to 60 % for nitrous oxides.
For example, at the start of the intake stroke of cylinder one, and when both the intake and exhaust valves of cylinder one are open (valve overlap period), cylinder three already starts its exhaust stroke with the exhaust valve open.
The primary characteristic of Deere's new technology is its low emission performance, which is achieved through the almost total elimination of an unburned fuel charge during the two-cycle engine's exhaust stroke.
One cylinder, called the "compressor", does the intake and compression strokes, while the other cylinder, called the "expander", does the expansion (or power) and exhaust strokes.
In this model, the intake, compression, combustion, and exhaust strokes occur simultaneously.
The intake, compression and exhaust strokes are all negative work, or the energy that the engine consumes to create mechanical work.
Toyota used a cylinder head that was very similar to a four-stroke engine cylinder head, so that the intake and exhaust strokes only occurred during half of the crankshaft's work.
