recently there has been an increased interest in natural gas as a fuel for
lean-burn SI engines because of the potential to reduce exhaust emissions.
While lean-burn technology has been used in heavy-duty, turbocharged natural
gas engines in power industry, only recently it has been considered for
light-duty applications. The performance of lean-burn engines for light-duty
vehicles is highly dependent on fueling system and its control. This paper
investigates the impact of natural gas fueling arrangement on engine stability
and exhaust emissions of lean-burn <span style="font-size:

system and an electronic port injection. Port injection system resulted in
better engine performance with regard to exhaust emissions and variability in
engine load than the mixer system. Catalyst performance for exhaust treatment
was affected by fueling arrangement, operating conditions and exhaust gas
temperature.</span
