Explanation of Honda’s Third Era Formula One Engine Development

Article of Honda R&D Technical Review F1 Special (The third Era Activities)

Summary

During the third era Formula One engine development, as a measure for increasing the engine power through an increase of engine speed, the enhancement of the induction static efficiency and weight reduction of the moving parts was focused on. From 2007, restrictions on the maximum engine speed and development of the engine except for the induction and exhaust system were introduced. Therefore, the focus of the development changed to practical use of dynamic effect of induction and exhaust pressure. Moreover, the driver-aids including traction control was banned in 2008, so attention moved to the development with the objective of shortening lap times, and including drivability enhancements.
Also, to comply with new regulations concerning the longer use of engines, the restriction of use of materials, and to respond to changes in actual usage in circuit running in accordance with the change of regulations, the subdivision of the endurance mode and results feedback was performed, which achieved durable reliability in parallel with performance enhancement.
This document describes the evolution of the engine as outlined above, and includes descriptions of technology such as the lap time evaluation method and tools.
