Engine Remanufacturing

Magnus Engineered Equipment (MEE) has been supplying cleaning equipment to leaders in the remanufacturing industry since the 1950’s. The remanufacturing process begins with a thorough cleaning of engine blocks and associated components so they can be properly inspected.  Removal of carbon, oil and grease, paint and other contaminants in necessary to inspect for microcracks and to make accurate measurements.  In addition, blocks, heads, connecting rods, crankshafts and camshafts are thoroughly cleaned to remove contaminants that can result in premature wear to internal engine components and early engine failure.

MEE has supplied thousands of cleaning systems to the remanufacturing industry and these systems generally employ immersion agitation to clean the substrates.  Recently, there has been interest in incorporating ultrasonic cleaning technology in order to more thoroughly clean oil passages and other hard to clean areas.

Ultrasonic cleaning utilizes transducers which convert electrical energy into acoustic energy in the cleaning solution.  Cavitation bubbles are formed which aggressively and quickly clean the substrate.  MEE supplies 20 kHz magnetostrictive transducers which deliver the highest cleaning power in the industry.  Unlike the more common piezoelectric transducers, magnetostrictive transducers are better suited for cleaning large substrates such as engine blocks, and MEE transducers deliver approximately 25 times more cleaning power than the 40 kHz piezoelectric transducers.

MEE equipment is well suited for handling large and heavy substrates.  Engine blocks in excess of 5000 lbs can be cleaned via immersion agitation and ultrasonic cleaning.  Figure 1 shows a typical cleaning tank supplied by MEE and Figure 2 and 3 show before and after pictures of engine components cleaned with MEE ultrasonics.  The use of 20 kHz ultrasonic cleaning coupled with immersion agitation cleaning delivers the most thorough and fastest cleaning for engine remanufacturing.
