Specific output is a measure of
internal combustion engine performance. It describes the efficiency of an engine in terms of the
brake horsepower it outputs relative to its
displacement. The measure enables the comparison of differently sized engines, and is usually expressed as
kilowatt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Wa ...
