PROSPECTS FOR INTERNAL COMBUSTION ENGINES AMONG ADVANCED ENERGY CONVERSION SYSTEMS

The position of internal combustion engines as major prime movers for transportation is examined. Advantages, associated with their impressively high level of flexibility and reliability are reviewed, and the disadvantages, due to their harmful environmental effects and relatively poor fuel economy, are outlined. Significant improvements could be made if combustion chambers could be developed that would serve not only as heat sources, but also as chemical reactors yielding acceptably low concentration of pollutants in the exhaust products. Fundamentally the recipe for this purpose is quite straightforward: operation with a completely pre-evaporized, homogeneously pre-mixed, and extra-lean charge. In practice, however, the attainment of this goal is riddled with difficulties. Means to remedy the situation are suggested and studies currently conducted in this connection are described.
