Development of High-Pressure Fuel Supply System for Formula One Engine

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

Summary

Important factors in boosting the performance of today’s Formula One engines include: the realization of the formation of ideal air-fuel mixtures and the achievement of greater combustion efficiency, through the use of shorter fuel injection periods and increased spray atomization resulting from higher fuel pressures; and, in addition to this, the achievement of stable combustion in the low-load operating range.
A comprehensive analysis of injector spray characteristics was conducted, leading to the development of a Honda-made high-efficiency, high-pressure fuel supply system. This enabled the achievement of a 15 kW increase in engine power.
