Document Type and Number:

WIPO Patent Application WO/2010/041478

Kind Code:

A1

Abstract:

Provided with a gas engine using low calorie gas, e.g. coal mine methane, having the concentration of methane of 50% or less as fuel in which the concentration of methane is increased so that low calorie gas injected into a subchamber can be ignited by an ignition plug and combusted. The gas engine using low calorie gas having the concentration of methane of 50% or less as fuel performs pressure swing adsorption treatment (PSA treatment) for obtaining methane gas having high concentration of methane by carrying low calorie gas into a PSA treatment unit and separating impurities from the low calorie gas by adsorption, and the gas subjected to such a PSA treatment is introduced into the prechamber where the gas is ignited by an ignition plug and combusted.
