Abstract

 This work is carried out to investigate the effect of connecting passage shape and flame initiation point on emission characteristics of torch chamber spark Ignition engine burning homogeneous lean mixture. This engine has been developed to achieve lean combustion of homogeneous mixture. A torch chamber for turbulence generation is used to extend the effective lean misfire limit and to increase the flame propagation velocity. The experimental study shows that the engine emissions of NO, CO and HC, mean effective pressure and specific fuel consumption are strongly dependent on the connecting passage shape and ignition point location.
 In the present work, two different passage shape (cylinderical straight passage of 9 mm diameter and convergent-divergent nozzle with 9 mm throat diameter) and three Ignition point location are used. The spark gap projection examined are 3.5, 8 and 13 mm electrode lengthes. The results show good fuel consumption and lower engine emissions of NO, CO and HC over the entire range of engine operation conditions when using convergent-divergent passage shape and the extended spark gap projection.
