Mazda introduces HAZUMI concept along with new 1.5-liter SKYACTIV-D diesel

Green Car Congress

This compact and lightweight clean diesel engine is designed for combustion efficiency, just like the larger displacement SKYACTIV-D 2.2. Conventional diesel engines generally have a high compression ratio; hence, the compression temperature and pressure at piston top dead center (TDC) are extremely high. Earlier post.)

POSTECH, Hyundai team develops new more thermally robust catalyst for NOx reduction with diesel engines

Green Car Congress

Andrews in the UK has developed a new, more thermally robust catalyst for NO x aftertreatment systems for diesel engines. Improvement of the thermal durability of the SCR catalysts would therefore be the key to maximizing the fuel efficiency, as well as to producing clean emissions from diesel engines. Park, G.

Eaton and Tenneco partner to produce new, integrated exhaust thermal management system to meet coming lower NOx standards

Green Car Congress

The integrated exhaust thermal management system will provide heat directly to the vehicle’s aftertreatment system, which is essential for reducing harmful exhaust emissions. Upon heating the SCR catalyst to approximately 200 – 250 degrees Celsius, the aftertreatment system can efficiently convert NO x into clean emissions (e.g.,

BYD introduces Type A battery-electric school bus with V2G technology

Green Car Congress

School buses can be charged overnight when energy demand is low, and clean emission free energy can be fed back into the classroom during school hours when the bus is parked keeping classrooms well-lit and students and teachers plugged-in. —Samuel Kang, BYD’s Head of Total Technology Solutions.
