Engineering evaluation of the General Motors (GM) diesel rating and capabilities
Abstract
K-Reactor`s number one GM diesel (GM-lK) suffered recurrent, premature piston pin bushing failures between July 1990 and January 1991. These failures raised a concern that the engine`s original design capabilities were being exceeded. Were we asking old engines to do too much by powering 1200 kw (continuous) rated electrical generators? Was excessive wear of the piston pin bushings a result of having exceeded the engine`s capabilities (overload), or were the recent failures a direct result of poor quality, poor design, or defective replacement parts? Considering the engine`s overall performance for the past 30 years, during which an engine failure of this nature had never occurred, and the fact that 1200 kw was approximately 50% of the engine`s original tested capability, Reactor Engineering did not consider it likely that an overloaded engine caused bushing failures. What seemed more plausible was that the engine`s failure to perform was caused by deficiencies in, or poor quality of, replacement parts.The following report documents: (1) the results of K-Reactor EDG failure analysis; (2) correlation of P- and C-Reactor GM diesel teardowns; (3) the engine rebuild to blueprint specification; (4) how the engine was determined ready for test; (5) testing parameters that were developed; (6) amore »

GM energy management: organization and results. [General Motors]
Energy conservation is not new to industry. The effective and efficient use of labor and materials including energy has been an important tool in cost control for many years. Today, an even greater emphasis must be placed on conserving energy while at the same time stimulating the longer term development of existing as well as new energy resources. Energy conservation in manufacturing can involve product material and/or finish specification changes, process changes or elimination, improved control of equipment, the installation of heat recovery devices and the consolidation of operations. GM's organization to meet these energy management challenges and some ofmore » -
Application for certification 1981 model year heavy-duty diesel engines - General Motors
Every year, each manufacturer of passenger cars, light-duty trucks, motorcycles, or heavy-duty engines submits to EPA an application for certification. In the application, the manufacturer gives a detailed technical description of the vehicles or engines he intends to market during the upcoming model year. These engineering data include explanations and/or drawings which describe engine/vehicle parameters such as basic engine design, fuel systems, ignition systems and exhaust and evaporative emission control systems. It also provides information on emission test procedures, service accumulation procedures, fuels to be used, and proposed maintenance requirements to be followed during testing.
