Remanufacturing Process Issues of Fuel Injectors for Diesel Engines

Abstract

Korean automobile industry is rapidly growing with annual domestic output already beyond a million vehicles. This fact is closely tied with constant demand on raw materials, energy consumption and, of course, concerns over exhaust emissions to atmosphere. Majority of automobile parts are usually used to be recycled and by this time the list of remanufactured parts are increasing. Remanufacturing is relatively new step in the industry. Several issues still present in remanufacturing of automobile parts such as information of remanufacturing, remanufacturing technology, absence of unified standards. This paper introduces diesel engine fuel injector remanufacturing process. Failure mode of the injectors is analyzed. Performance test methods are discussed by comparing two different OEM remanufacturing specifications. Also, simple process is considered from an independent remanufacturing company.
