Honeywell Gasoline DualBoost Turbochargers Application: Honeywell gasoline DualBoost turbo can be used on two types of engines: those with a focus on fuel economy through engine downsizing and down speeding and those with a focus on performance enhancement. It is mostly suited for engines with a displacement of 1.4L and above.Honeywell Gasoline DualBoost Turbochargers Key Features: 1.While turbos in production today generally feature radial turbines, in which the air flows in vertically and exits horizontally, the latest gasoline turbo technology from Honeywell uses the industry’s first axial turbine with air flowing in horizontally and exiting in the same direction. While axial turbines are common in Aerospace, adapting them for automotive applications has required some serious out-of-the-box thinking on the part of Honeywell engineers.
2.Three features have made Honeywell’s axial turbines unique: zero-reaction aerodynamics, no nozzles and tall-blade design. The three characteristics, working in unison, enabled the axial turbines to attain higher specific speed, allowing for smaller size for the same flow, thereby lowering inertia by up to 40 percent. In addition, the axial turbines are designed for good efficiency under pulsating flows and improve catalyst light-off.
3.The adoption of axial turbine design, due to its smaller size, has created two technical challenges: speed match with compressor and thrust load balancing. On both accounts, Honeywell’s dual-compressor technology is a perfect match.
4.First adopted in Honeywell’s award-winning VNT™ DualBoost turbocharger for diesel engines, the dual-sided compressor provides a significantly higher operating speed for the same air flow. As a result, it’s an ideal speed match for the axial turbine wheel, and its smaller size reduces inertia by 20 percent, contributing to increased throttle responsiveness. The dual-sided design also allows for “zero thrust” from the compressor wheel, so there’s no need for the turbine wheel to balance “pulling” from the compressor side of the turbo. Honeywell Turbo Technologies has taken a fresh look at the design of the gasoline turbocharger and has redefined the aerodynamic layout of both the compressor and the turbine stages. It has been able to increase overall turbo efficiencies, especially at low speeds and in transient conditions and this combined with substantially reduced mechanical inertias has provided significant improvements in engine transient torque response.
