How does a Miller-cycle engine work?

The standard four-stroke engines are called Otto-cycle engines. They are named after Nikolaus Otto, who invented this type of engine in 1867. In the same way, Diesel-cycle engines are named after inventor Rudolf Diesel. Ralph Miller patented his Miller-cycle engine in the 1940s.

A Miller-cycle engine is very similar to an Otto-cycle engine. The Miller-cycle uses pistons, valves, a spark plug, etc., just like an Otto-cycle engine does. There are two big differences:

  • A Miller-cycle engine depends on a supercharger.
  • A Miller-cycle engine leaves the intake valve open during part of the compression stroke, so that the engine is compressing against the pressure of the supercharger rather than the pressure of the cylinder walls. The effect is increased efficiency, at a level of about 15 percent.

What is LNGo™ system?

The LNGo system is a modularized, compact,redeployable, distributed natural gas liquefaction plant capable of producing 6.000 - 8.000 gallons of LNG per day.

The system is made up of four packaged skids: power, compressor, process, and gas-conditioning modules that work together to offer a decentralized, distributed approach to meet the growing demand for LNG fueling.
