The relief throttle allows fuel to pass through freely in the direction of the injection nozzle. The pressure wave travelling toward the injection pump from the injection nozzle is caused by the secondary pumping action of the needle valve as it closes; this is attenuated by the relief throttle and pre\u00advented from returning to the injection nozzle where it would otherwise cause secondary injection. This in turn would increase the hydrocarbon content of the exhaust gases.<\/div>\n<\/div>\n<\/td>\n
