The Alabama Technology Network, Inc. (ATN) provides technical assistance, management assistance and training that complements workforce and economic development. The ATN center at the University of Alabama in Huntsville (UAH) has focused on lean manufacturing. This paper summarizes the principles of “lean”, presents three phases to implementing lean, and illustrates its application in a training simulation of a setup/changeover reduction. Finally, success stories show how UAH is helping many small and medium size manufacturers improve rapidly using lean techniques.

It has been known for more than 50 years that some diesel engines could be fueled for short periods with vegetable oils, either neat or with hydrocarbon fuel additives. World overproduction of soybean oil is increasing its potential as an economical diesel fuel extender. The subject test program was undertaken to determine long-term effects of this alternate fuel on a modern, high-speed diesel engine. The choice of a vegetable oil (soybean oil) as an alternative diesel engine fuel or fuel extender rather than the other major biomass motor fuel (ethanol) is related to the relative properties of these fuels. The common U.S. vegetable oils are much closer to hydrocarbon (No. 2D) diesel fuel than is ethanol in both cetane rating and volumetric energy content. Unlike ethanol, the vegetable oils can be blended 1:1 with No. 2D fuel to produce engine power and volumetric fuel consumption levels practically identical to those obtained with 100% No. 2D fuel.
