Fuel Injection System for Compression Ignition Engines

Abstract: 

An improved fuel ignition system for a compression-ignited engine having a fuel combustion chamber and a glow plug located therein. The glow plug has a resistance heating element that is positioned in the combustion chamber. The resistance of the resistance heating element is sensed and compared with a set value. The result is utilized for the purpose of either varying the power supply to the glow plug or determining the length of on and off time for the glow plug while the engine is running.
