It means Stroke is longer than the Bore. Due to the longer stroke, the engine makes good torque at relatively low rpms.
more time available for combustion so low quality fuel can be burned.
improved thermal efficiency{heat converted into useful work / total heat supplied}
Reduction in nox due to higher compression ratios and reduced combustion chamber temperatures.
Explain the advantages of four-stroke engine over two-stroke engine
Pollution - 4 stroke has far less unburnt hydrocarbon in the exhaust.
One advantage of having a four stroke petrol engine is the fuel economy. A disadvantage of the engine is in the cold weather they are harder to start.
The length of the crankshaft throw is the stroke of the engine.
It is possible to use 4-stroke oil in a 2-stroke engine in an emergency situation. You should not use this oil in the long term as it will damage the engine.

two stroke
wartsila, this is the name of an engine , which is 2-stroke long diesel engine with the 1,09,000 brake horsepower.
Why the fuel consumption is less in 4 stroke engine as compared to 2 stroke engine
in my opinion a two stroke engine is a better quality engine as compared to a four stroke engine!
It refers to the throws of the crankshaft/distance the piston moves. It usually is compared to the bore of the engine. An example a 302 4"bore x 3"stroke is a short stroke motor, by comparison a 5.4L ford v8 3.552" bore x 4.165" stroke.
