JAC and Ricardo develop production version of HyBoost concept; seeking 30% boost in fuel economy with same performance

Green Car Congress

SEPTEMBER 30, 2015

Anhui Jianghuai Automobile Group Co Ltd (JAC) and Ricardo are collaborating on a project to develop the Ricardo HyBoost concept ( earlier post )—a combination of low-cost technologies to deliver improved performance and fuel economy which featured recently in the Ricardo Centenary celebrations —into volume production on a JAC vehicle.

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

Green Car Congress

FEBRUARY 1, 2009

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.

In comparison, they noted, the technology for bio-chemical ethanol production from cellulosic biomass is not sufficiently developed yet. There is no strong advocacy for methanol (unlike ethanol) as a transportation fuel; therefore, they said, it has been displaced by ethanol as oxygenate of choice in gasoline blends. It is a safe fuel.

Ford E85 Direct Injection Boosting Study: A Less Expensive Alternative to Diesel

Green Car Congress

APRIL 26, 2009

Using the E85 boosting concept requires two fuel tanks and vehicle owner acceptance of dual fueling. The resulting higher BMEP levels allow downsizing of the engine at equivalent vehicle performance. The MIT team spun off a startup— Ethanol Boosting Systems , LLC (EBS)—in 2006 to commercialize the concept. Earlier post.)

Due to a new actuator concept, the power can be transferred by the overlapping shifting through the disc clutches from one speed to the other without using a synchronisation or a dog clutch. This architecture extends the range by up to 10% in electric mode. The entire control for the hybrid powertrain was developed by Getrag.

Though the PHEV combines the two types of energy and power, it is not merely a temporary “transition” between gasoline and diesel cars to pure electric cars. Since it can refuel from a standard household outlet and from a gasoline station, it needs no new infrastructure. It is much more than that. Conclusions. slow charge.
