New generation power unit officially named as the Energy F1-2014
Renault has revealed its new generation power units for the 2014 season of the Formula One World Championship. Set to conform to the new regulations, the power unit is comprised of a 1.6-liter V6 turbocharged engine with energy recovery system.
With only 100kg (down by 35% from current regulations) of fuel permitted per race for the new season, the new power unit improved its fuel efficiency even though its power output exceeds the ones generated by the current V8 F1 engines.
“From 2014 we will bring engines to the fore and redress the balance in F1. An engine is the heart of a car, from next year it returns to the heart of our sport.” Alain Prost, Renault ambassador and four-times Formula 1 World Champion
Renault has named the new power unit as the 'Energy F1-2014' and consists of several main components like the 1.6-liter turbocharged V6 engine, energy recovery system (ERS), motor generator unit - kinetic(MGU-K) and motor generator unit - heat (MGU-H).
‘‘The next generation of F1 cars will be powered by a turbocharged 1.6-liter V6 internal combustion engine of around 600 bhp, plus around 160 bhp of electrical propulsion from the energy recovery system, meaning the term ‘engine’ will no longer fully describe a car’s source of propulsive power. It is more relevant to refer to the complete system as a ‘Power Unit.’’ Rob White, Deputy Managing Director.
The MGU-H is connected to the turbocharger and recovers energy from the exhaust while the MGU-K is connected to the crankshaft and recovers energy from kinetic energy produced from braking.
‘‘Overall, the sound pressure level (so the perceived volume) is lower and the nature of the sound reflects the new architecture. The car will still accelerate and decelerate rapidly, with instant gearshifts. The engines remain high revving, ultra high output competition engines. Fundamentally the engine noise will still be loud. It will wake you from sleep, and circuit neighbors will still complain. The engine noise is just a turbocharged noise, rather than a normally aspirated noise: you can just hear the turbo when the driver lifts off the throttle and the engine speed drops." Jean-Michel Jalinier, President of Renault Sport F1.
