TRD CHOOSES SUPERCHARGER FOR PERFORMANCE AURION
New TRD Aurion is Toyota’s first supercharged model in Australia.TRD chose supercharging over turbocharging to achieve instantaneous engine response and impressive low-down torque.At just 1800rpm, the supercharged TRD Aurion engine matches the 336Nm peak torque of the naturally aspirated Aurion engine.TRD Aurion’s Eaton TVS supercharger is driven by a V-belt, off the engine’s crankshaft.According to a Toyota Australia survey conducted in 2001 using vehicles with data loggers, Australian driving preferences are unique.Australian drivers want instantaneous response and low-down torque - to accelerate briskly to the speed limit like Americans.But they also want to brake late into corners and maintain corner speed, like European drivers.TRD worked with leading Melbourne-based motorsport engineering company Harrop Engineering Australia on supercharger development.Harrop is one of only two Eaton agents worldwide.
Its applications engineering role in the TRD Aurion engine development included supercharger selection, design and casting of the supercharger casing and inlet manifold, and design of the drive-belt pulleys.It also carried out the finite element analysis for stress in the engine and airflow analysis.TRD’s guidelines in the supercharged engine development included retaining the original equipment Aurion fuel rail and minimising the number of unique service tools.
TRD AURION HAS NEW EATON TVS SUPERCHARGER
TRD Aurion is the first OE vehicle to feature Eaton’s new-generation four-lobe supercharger technology.It has the new Eaton TVS (Twin Vortices System) supercharger.The new four-lobe rotor Eaton TVS design offers significant advantages over three-lobe supercharger designs.Its key benefit is greater thermal efficiency, which results in a lower inlet manifold temperature, improved charge density and increased performance.
Other benefits include a higher pressure ratio, increased airflow capacity for the same supercharger package size, increased operating range (rpm), higher efficiency and quieter operation, improved fuel economy at cruising speeds and instantaneous boost response.The four lobes have 160 degrees of twist over their length, compared with 60 degrees in Eaton’s current three-lobe supercharger designs.The large lobe twist allows for a larger inlet port, improved airflow and a larger useable outlet port area.
