Pneumatic hybrid engine on the test bench. Researchers at ETH Zürich are developing a pneumatic hybrid engine—an internal combustion engine connected to a compressed air tank instead of a battery system. The compressed air supply also allows extreme downsizing. Rüegg / ETH Zurich. Click to enlarge.

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.

Comparison of Emission Standards (g/mi). . We see dramatic downsizing and boosting [as] something that’s going to for gasoline engines especially. We also expect a lot of hybrids and electrification. To be able effectively to implement downsizing and downspeeding, good low-end torque is essential. John Kirwan.

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.

GDCI engine was significantly better than advanced production spark injection gasoline engines, and comparable to very efficient hybrid vehicle engines at their best efficiency conditions (214 g/kWh). A practical powertrain system with robust PPCI combustion is needed, including injection, valvetrain, boost, and exhaust subsystems.

Deploying the full range of combustion engine technologies, including hybrid electric vehicles, would be sufficient to reduce the fleet average CO 2 emissions to 70 g/km, the study found. Source: The ICCT. Click to enlarge.

The alternative-fuel car evolved to reduce exhaust emissions and other problems derived from burning fossil fuels. The PHEV (Plug-in Hybrid Electric Vehicle), a subset of the electric car, combines a primary electric motor with a much smaller back-up engine fueled with a hydrocarbon/biofuel mix. The word “hybrid” is misleading.
