The vehicles on which the research was based were representative of current production models at the more aggressive end of the downsizing spectrum in terms of engine capacity and output, but modeled with a future three cylinder 1.5 The cost comparison is with respect to a Euro 5 baseline. liter diesel engine.

The pneumatic hybrid engine, which follows the downsizing and supercharging paradigm, offers a fuel-saving potential that is almost equal to that of hybrid electric powertrains while inducing much lower additional mass and cost penalties, according to the ETH Zürich researchers. The compressed air supply also allows extreme downsizing.

Comparison of Emission Standards (g/mi). . We see dramatic downsizing and boosting [as] something that’s going to for gasoline engines especially. To be able effectively to implement downsizing and downspeeding, good low-end torque is essential. Differentiated Analysis of Downsizing Concepts”). CA LEV US T2B2 CA SULEV.

The aftertreatment program within the 21CTP should be continued, and DOE should continue to support the activities of the Cross-cut Lean Exhaust Emissions Reductions Simulations (CLEERS) program that interface with the activities of the aftertreatment technical community at large.

In a 2010 paper, Roger Stone, Engineering Director, Torotrak noted that conventional turbo- and supercharging technologies are more than capable of delivering the required peak power and torque levels from downsized engines but suffer from a number of. It gives the next generation of downsized powertrains ‘big-engine’ response.

Due to the lower exhaust enthalpy of lower temperature engines using PPCI, it is difficult to produce intake boost with acceptable boost system parasitis. A practical powertrain system with robust PPCI combustion is needed, including injection, valvetrain, boost, and exhaust subsystems. —Sellnau et al. kWh and FSN 0.1,
