The “RA168E”, a turbo-charged V-6 1.5-liter engine, was developed by Honda Motor Co., Ltd. for the 1988 Formula One Championship Race events.
Despite boost restrictions (2.5bar), the engine boasts a maximum power of 504 kw (685 ps), which is equivalent to 336 kw/ℓ (457 ps/ℓ). The development of improvements on the fuel consumption of this engine allowed the achievement of a minimum brake specific fuel consumption of 272 g/kwh (200 g/Psh).
This paper Introduces major specifications, along with power output and fuel consumption characteristics of the RA168E racing engine. In addition, the effects of intake air temperature, boost, air-fuel ratio, fuel temperature and fuel ingredients on fuel efficiency and power output are presented.
