We Working all Sorts of Diesel Engine
Diesel engines are also categorized by their size and power output.
Small:
Used in light trucks, agricultural equipment, and construction machinery. Engines with power output up to 20 HP are predominantly used in light agricultural equipment, small generators, and garden machinery
Medium:
Often found in heavy-duty commercial trucks. Medium power diesel engines, ranging from 10 HP to 25 HP, are widely used in applications requiring slightly higher power outputs such as small construction equipment, compressors, and industrial machinery
Large:
Power trains, ships, and large generators. Large diesel engines are used for industrial purposes and huge power plants, typically six-cylinder, eight-cylinder, and twelve-cylinder engines that are used in the power range of these diesel engines from over 1000 kW to 1 to 2 megawatts
