Comparisons are made of methods of construction and technical performance which illustrate progress in engine design over the last 40 years, and the contribution made in development by engine component specialists.
Predictive techniques and uses of specialised rig tests used in piston assembly development are described, which reduce development costs and time, and improve engine reliability. Quality control techniques are briefly compared and the need is shown for a greater degree of “in-process” control, to be developed in the next decade, to obtain improved quality levels with no concurrent cost increase.
It is suggested that the main prime movers in use during the first two decades of the next century will still be recognisable as reciprocating engines, but that efficiencies will be improved by reduced friction and by a more efficient response to engine load demand.
It is believed that in the search to conserve the world's fuel resources, and in the increasing demand for improvements in the ecology and consumer protection, there will be an increasing demand - for the component suppliers.
