Mazda not only has homogeneous charge compression ignition technology on the horizon for a debut next year, the Japanese manufacturer also has filed a patent application for a triple-charged engine, which was recently published by the United States Patent and Trademark Office (USPTO).
The diagram and drawing filed with the USPTO reveal a petrol engine with what appears to be a pair of conventional, exhaust-driven turbochargers, which operate in parallel with an electrically-operated supercharger. The electric supercharger would be provide low-end power while the pair of turbos spool up.
Mazda’s electric supercharger is likely to be run off its own i-ELOOP capacitive storage system, which, in the Mazda 6, recovers energy from braking and converts it to electricity, which it stores in capacitors for use towards equipment such as the air-conditioning, sound system and lighting.
Interestingly, one of the images in the patent filing reveal the engine configured longitudinally, which means a rear-wheel-drive setup. Currently, the Miata/MX-5 is the only such configured car in Mazda’s line-up. The Hiroshima-based automaker’s Skyactiv-X engine will be equipped with an electric supercharger, though it was not clear if that powerplant adopts the triple-charger setup in this patent filing.
Mazda says it will continue to perfect the internal combustion engine, which it says will remain the main source of power for vehicles globally for years to come, and hence has the greatest potential for emissions reduction. Its launch plan for future technologies sees Skyactiv-X come to market in 2019, with the second-generation Skyactiv-D (diesel) engines due a year later.
Looking to sell your car? Sell it with Carro.
sounds expensive to own and maintain
most likely the next rx9?
Well done Mazda
Mazda spends most of their money on research. They don’t beg for money
With tebo snails ontop, this gonna be a very high fronted car.
The owner clearly have zero fux to give to those thinking that the Macca looks kinda weird in that colour.
fantastic mazda
Proton ricardo engine more advanced.
A triple charged MX-5? Wow! That go cart would fly. All those people who criticized it’s lack of power had better start saving up for one or better still, eat their words.
Very likely engine for RX-9, rotary is already dead with new emission standards.
mazda oh mazda …still focus on combustion engine??? skip
Mazda loves weird different than others approach. Mazda be like, well others are succesful doing that, lets try something different, something else.
Another innovation from Mazda. Kudos.
Seems like Mazda could bring forth a RWD model, for this longitudinal design…a premium Mazda 6 Coupe aka the re-incarnated “MX-6”, using a stretched Sky-Activ RWD platform of the ND Miata/MX-5.
