Abstract
Assuring continuous emission and fuel consumption standard compliance for vehicles in operation, a total production process for combustion engines has been developed, called original equipment remanufacturing. Utilizing over-sized dimensions, genuine spare parts and original factory specifications and tolerances, large quantities of exchange engines and cylinder head assemblies were already produced and installed into vehicles.
In the course of the machining process some original standard dimensions are changed to over sizes (bores, pistons, rings, bearing shells, valve stems) or to under sizes (shaft journals, block height, cylinder head height, piston height). Dimensional changes may lead to changes in engine parameters like: cylinder volume, oil pressure, compression ratio, combustion process and emissions.
In order to avoid any undesired changes in engine performance, documented methods and procedures are used by OE Remanufacturers to compensate for dimensional changes which results in returning to original specified operating parameters.
In conclusion, authors urge R&D engineers to exercise a unique approach in early design, called “Design for Remanufacturability”
