Since 2013, the share of premium gasoline in total motor gasoline sales in the US has steadily increased to 11.3% One significant trend is engine downsizing coupled with turbocharging. The pressurized intake air allows a turbocharged engine to produce more power compared with a naturally aspirated engine of the same size.

V-Charge system with mechanical variable drive outperforms conventional boosting methods on downsized gasoline engine. These will include simulation using a GT-Power model and engine dynamometer testing which was carried out at the University of Bath Powertrain and Vehicle Research Centre (PVRC). Click to enlarge.

Federal-Mogul Corporation has developed a lightweight, high-strength aluminium piston that enables engine manufacturers to increase the power density and efficiency of boosted, direct injected gasoline engines. Specific power outputs in engines are likely to increase from current levels of around 95 kW/L to 130 kW/L to coming years.

Cost of the new engine relative to gasoline baseline. The approach that Cummins and partners have taken features: Replacing the aluminium V8 gasoline engine and emission control system with smaller diesel (2.8-liter) Lightweight steel pistons provide reduced friction & compression height with increased power density.

The need to reduce CO 2 emissions is leading to downsized engines, heavily boosted by turbo- or supercharging. But while these engines easily reach high peak power and torque figures, they struggle to provide the required low-speed response. —Torotrak engineering manager David Burtt, co-author of the paper. —David Burtt.

Simulation study finds Miller version of Scuderi engine can deliver twice the BMEP as naturally aspirated version, theoretically enabling 50% downsizing while maintaining performance. Applying the Miller cycle to the Scuderi engine (right) entails downsizing of the compression cylinder. Source: Scuderi. Click to enlarge.
