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.

Dresser-Rand Guascor® SFGRD Engine Series

Guascor SFGRD gas engine family

The Dresser-Rand Guascor® SFGRD engine series is a spark ignited, rich burn gas engine with better flexibility for load acceptance and emissions control. This series meets U.S. emissions standards with inexpensive exhaust after-treatment. This engine series can be used in power generation, cogeneration, tri-generation, and mechanical drive applications.

 

The SFRD 560 containerized genset of 835 kWb Power output/1120 BHP (around 800 ekW) with natural gas is used in the LNGo™ system, a modularized, portable natural gas liquefaction plant.

 

    Output range from 281 to 870 kWb (1800 rpm)

    Powered by natural gas

    Supplied as a stand-alone engine, genset, or in a fully assembled containerized unit (noise insulated if required)

 

Features include :

 

    Wet exhaust manifold

    Single / double step intercooler

    Oil cooler in main / auxiliary circuit

    194°F (90°C) main cooling circuit temperature

    131°F / 104°F (55°C / 40°C) intercooler cooling circuit temperature

 

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.
