Development of formula one V12 high-performance engine

摘要

The "RA122E/B" is a natural aspiration V 12 3.5 litter engine, and was developed by Honda Motor CO., Ltd. for the 1992 Formula One Championship Racing season. The development program for the racing engine was not confined to the pursuit of light weight, compact size and high performance. It was far racing in scope, including the provision of a pneumatic valve return system, variable induction system, five-section scavenging system and motor driven throttle system to give the engine a high level of functionality. The main characteristics and the new systems incorporated in the "RA122E/B" engine increased the maximum engine speed, enchanced thermal efficiency and contributed to lower friction. The maximum power was 570kW at 14,400rpm, and the engine has a very light dry weight of 154kg. This paper describes the main specifications, performance and new systems incorporated in the "RA122E/B" engine.
