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

Green Car Congress

The Ricardo HyBoost concept is based on a downsized, highly boosted turbocharged direct injection gasoline (TDGI) engine giving improved fuel economy at low cost, linked to a 48V electrical architecture including a belt starter generator (BSG), DC-DC converter and a lithium-ion battery for energy storage.

Researchers propose evaluating alt fuel efficiency based on energy rather than volume; impact of ethanol on vehicle efficiency and GHGs

Green Car Congress

Relative changes in vehicle energy efficiency (VEE) (km/MJ) on ethanol/gasoline blends over those on gasoline for different blending levels. Several recent highly cited LCAs that have incorporated vehicle efficiency differences between gasoline and ethanol/gasoline blends could potentially be misleading.

Toyota introduces the B-segment Yaris Hybrid at Geneva; anticipating 20% of Yaris model range sales in first year

Green Car Congress

The new Yaris Hybrid, which is equipped with a version of the downsized hybrid powertrain featured in the Prius c/Aqua ( earlier post ), is a major step in the company’s full hybrid European roll-out strategy. The downsized full hybrid system combines the new 1NZ-FXE 1.5-liter liter Atkinson Cycle gasoline engine is 16.5

Porsche takes top two spots at Le Mans, Audi third

Green Car Congress

Porsche competed this year in the 8 MJ category (8 MJ of recovered energy per race lap—the highest of the current four energy categories in the LMP1 class. The amount of liquid fuel that may be used in a lap decreases in proportion to the amount of electrical energy a driver is able to employ.). Click to enlarge.

Simulation study suggests ORC waste heat recovery system could deliver potential 7% improvement in fuel consumption in a PHEV on highway

Green Car Congress

Starting from a energy-based powertrain simulation model validated on experimental data from the PHEV, the researchers conducted a first- and second-law analysis to identify the potential for engine waste heat recovery, considering a variety of driving cycles and assuming the vehicle operating in charge-sustaining (HEV) mode.

Kia launching new diesel 48V mild-hybrid powertrain in 2018 on Sportage; more models to come

Green Car Congress

The new “EcoDynamics+” powertrain supplements acceleration with electric power from an additional 48-volt battery and extends combustion engine ‘off time’ using a new Mild-Hybrid Starter-Generator unit. The adoption of the MHSG also means the conventional starter motor can be downsized and used primarily for cold starts at low temperatures.
