Steel Remains Dominant Material in the Stressful Environment of High-Performance Engines
Of the ten best engines for 2005, five are repeat winners from 2004. A review of recent specifications of the five repeat engines shows that there are no significant developmental changes. Consequently, the study, which was conducted by automotive design engineering consultant Alan Hine, concentrates on the new entries.
The engines outlined in this report reflect the auto industry's drive to achieve lighter and more efficient power plants. The increase in torque and horsepower is evident, as is the drive by the manufacturers to provide a more powerful, yet more fuel-efficient engine. More efficient use of forged crankshafts and connecting rods will provide the mass reductions in the future. Lighter steel flywheels will also help lowering the rotational masses. These efficiencies will allow the engine to rev faster and provide more fuel efficient power plants with more power. To achieve a lighter and more powerful, fuel-efficient engine, the choice of steel components would be wise choice. Dr. Hine's report is available at the steel industry web site, www.autosteel.org.

Based
on Ward's Auto World's list of the Ten Best Engines for 2005,
AISI compiled a report noting that automakers today combine advanced
material and process technology and materials to make light, more
powerful, compact engines. While the traditional approach has been
the implementation of unique block design and manufacture, the reduction
in size and volume has led to more steel use in the reciprocating
components. Steel usage has become a necessity rather than a trend.
