The power and efficiency losses that normally accompany the slow burning of lean mixtures may be reduced by using a torch ignition system. The torch chamber provides turbulence which can reduce the combustion interval and possibly reduce exhaust emissions. The use of a directed torch nozzle enables the optimum torch jet direction to be found. In recent testing, a late-firing torch, in conjunction with a standard ignition system, was used to provide additional energy to supplement cylinder turbulence. The use of the late-firing torch provided a reduction in HC emissions but increased fuel consumption.
