OPERATION METHOD OF GASSCOMPOSITIONNCHANGE INTERNAL COMBUSTION ENGINE

摘要

PURPOSE:To cut short warming time and burn gas stably by supplying warmed-up gas for a main combustion chamber in run-in and composition changed gas for a sub-combustion chamber with the aid of a gas supply pipe and a switch opening-and-closing valve parallelly furnished. CONSTITUTION:Warmed-up gas fed from a composition change unit 10 in run-in passes through a gas cooler 11 and a bypass 14. At this time a main-combustion chamber opening-and-closing valve 15 opens and a sub-combustion chamber opening-and-closing valve 16 remains closed that warmed-up gas filled in a composition-change gas supply pipes 8, 8a supplied for only the main combustion chamber 2. Then the composition of the gas is changed to produce inflammable gas, which passes through a flow control valve 12 and flows through the supply pipe 8. At this time the main combustion chamber opening-and-closing valve 15 is closed and the sub-combustion chamber opening-and-closing valve 16 remains open that the inflammable gas runs through the supply pipe 8b and is supplied for only the subcombustion chamber 3. No gas including much N2 and CO2, sent from the warmed-up composition change unit 10, is supplied for the sub-combustion chamber that misfire or irregular rotation is prevented.
