On fuelinjected vehicles, poor fuel atomization is a common cause of HC problems. For all of these remaining possibilities, checking for uneven power output amongst cylinders will usually help to track down the cause of the problem. Possible Causes of High Carbon Monoxide (CO) Emissions. High CO means too much fuel.
available high temperature CO/HC sensors along with an indigenously developed metal oxide (MOG) sensor array are evaluated in batch firing experiments with reference to the data sampled by a HTFTIR analysis system. Finally, the signal stability of the sensors was investigated by repeated exposure to CO/air gas mixtures.
