variant but with fuel economy of a strong hybrid. HyBoost achieves this by combining aggressive 50% downsizing of the engine with an electric supercharger for transient low-speed performance, and a micro-hybrid stop-start and energy recuperation systems, Boggs said. Downsizing the 2.0-liter Micro-hybrid market.

Concept: Downsized and Supercharged Hybrid Pneumatic Engine for 30%+ Reduction in Fuel Consumption

Green Car Congress

Schematic of downsized and supercharged four-stroke hybrid pneumatic spark injection engine. The reduction in fuel consumption is obtained mainly through enabling the effective use of a heavily downsized engine, rather than from regenerative efficiency. Source: ETH Zürich. Click to enlarge.

ETH Zürich Developing Pneumatic Hybrid Engine; Approaches Hybrid-Electric Performance at Lower Cost

Green Car Congress

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. If fuel is also injected, the engine responds quickly. Rüegg / ETH Zurich. Click to enlarge.

A123: Increasing 48V battery power up to ~25 kW enables advanced mild hybrid capabilities with greater fuel savings

Green Car Congress

Improving battery power to such as level would further enable hybridization to near-HEV levels as well as engine downsizing, thereby enabling fuel economy improvements beyond the current 10-15% MHEV limit. Current MHEV systems typically consist of an engine coupled to a belt-integrated starter generator (BISG).

Team from GM, Ford, FCA reviews how to calculate engine efficiency benefits of high octane fuels

Green Car Congress

A team of engineers from GM Powertrain, Ford and FCA have published a detailed review of how to estimate the engine efficiency benefits of higher octane fuel—e.g., fuel with higher ethanol content—for part- and full-load operation for different engine types and fuel assumptions. —Leone et al.

Scaleo chip introduces Advanced Motor Events Control (AMEC) technology for internal combustion engine and electric motor control

Green Car Congress

France-based Scaleo chip has introduced AMEC (Advanced Motor Events Control), a technology for internal combustion engines and electric motors control. AMEC—a flexible microcontroller interface for engine control—will be first available in OLEA, Scaleo chip’s new family of microcontrollers optimized for powertrain systems.
