Output per Cylinder

Output per Cylinder

 

the power developed in a single cylinder of a reciprocating engine, such as an internal-combustion engine or a steam engine. The output per cylinder depends on the mean effective pressure, the mean piston speed, and the cylinder diameter. The primary method used to increase the output per cylinder consists in raising the mean effective pressure. Thus, between 1955 and 1975, the output per cylinder of medium-speed diesel engines was almost doubled; of this increase, 75 percent was obtained by raising the mean effective pressure.

The output per cylinder of low-speed two-cycle diesel engines may be as high as 4,000 hp (1 hp = 0.7355 kilowatt). The maximum output per cylinder is 1,500 hp for medium-speed diesels, 100 hp for automotive diesels, 50 hp for tractor diesels, 40 hp for automotive carburetor engines, and up to 1 hp for engines with a displacement of not more than 0.85 liter. The output per cylinder of two-cycle engines is higher than that of four-cycle engines.

By increasing the output per cylinder from 185kW to 220kW, it follows that fewer cylinders will be needed when installed in 60Hz generating sets.
The impressive power output per cylinder of the Wartsila engines was also cited as a factor in the contract award decision.
The output per cylinder is 129 hp/cyl, resulting in the following power generation drive outputs: 1125 kW for the V-12 model TCG 2020 OLS and 1500 kW for the V-16 TCG 2020 OLS model.
