A generator is a device that transforms mechanical or chemical energy into electrical energy to provide portable power to operations or to prevent discontinuity of activities during a power outage. In particular, a diesel generator is the combination of a diesel engine with an electric generator to generate electrical energy. A generating set (genset) comes in various sizes, packaged to meet different needs, set sizes range from 8 to 50 kVA single phase or three phase for use in homes, shops, and office, with the larger industrial generators, up to 2500kVA are used. At Kubota, we provide a wide range of gensets to meet your business needs.
A four stroke cycle engine is an internal combustion engine that utilizes four distinct piston strokes (intake, compression, power and exhaust) to complete. The piston makes two complete passes in the cylinder to complete one operating cycle. An operating cycle requires two revolutions (720 °) of the crankshaft. The four stroke cycle engine is the most common type of small engine. A four stroke cycle engine in one operating cycle consists of, including intake, compression, ignition, power, and exhaust strokes.
To release the chemical energy in diesel effectively, an atomized form of the fuel is made to contact with high temperature and high pressure air. A diesel engine usually operates by repeating a cycle of four-stage or strokes combustion principle, also known as the otto cycle. The chemical energy release (combustion) is effectively transferred as mechanical rotational energy. The operation of a diesel engine is all about producing high temperature and high pressure air continuously.
There have been different opinions across industry experts over what makes a good diesel engine. It could probably be due to different requirements that each individual has over the use of their engines. However here are some of the common factors that came up regularly while speaking to industry experts, and most use them to evaluate what makes a good engine.
