Research and Development of High-Speed, High-Performance, Small Displacement Honda Engines

<div class="htmlview paragraph">Honda has produced high-speed, high-performance, 4-stroke cycle gasoline engines by applying advanced technology gained through the design and development of motorcycles and automobiles for Grand Prix racing. Some of Honda's racing engines attained performance as high as 260 bhp/liter or nearly 4.3 bhp/cu in. at speeds of up to 25,000 rpm. This paper describes our technical approach for optimizing combustion efficiency, volumetric efficiency, and mechanical efficiency-the keys to high-speed, high-performance engines.</div>
