The EPC-110/120/100E/150 Air/Fuel Ratio Controls are
applicable
to most carbureted natural gas-fueled engines. This universal
line
of emission control systems includes three specific models – two
of them for stoichiometric applications using a catalytic
converter
(EPC-110/120 and EPC-100E), and a third model used exclusively
on
carbureted, lean-burn engines (EPC-150).
