Carbon Monoxide (CO): It is a colourless, highly noxious gas which forms where the combustion
of fuels containing carbon proceeds under(possibly local) air starvation. In modern DG sets,
optimisation of air/fuel mixture formation and use of constant pressure type turbo charging, successfully
reduces the CO content of exhaust gases even with the poorest qualities of fuel grades. This type of
engine design meets even the stringent standards set by such environmental agencies like TA-Luft of
Germany.
