Baua Electric

Automakers often bring their dirtiest cars to Australia, and don’t offer better and cleaner electric models in the country. The US EPA has long had what is referred to as a “ footprint rule, ” which allows larger vehicles to pollute more. As a result, the average new car in Australia consumes 6.9L/100km, 100km, compared to 4.2L

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

Green Car Congress

The system is referred to as MZD Connect in other markets.) The result is cleaner combustion with low NO x and soot emissions. Also due to the low compression ratio, the SKYACTIV-D diesel engine also burns cleaner, discharging far fewer nitrous oxides while producing virtually no soot. Source: Mazda. Click to enlarge.

Santa Monica signs 5-year deal with Clean Energy for renewable LNG for bus fleet; deploying CWI Near-Zero NOx engine

Green Car Congress

The 5-year deal, worth an estimated $3 million per year, will enable BBB to continue using Clean Energy’s Redeem brand of renewable natural gas (RNG), rated up to 90% cleaner than diesel. It also reduces in-cylinder combustion temperatures and creates an oxygen-free exhaust, which then enables the use of a TWC for NO x control.

KAUST team develops computational model for simulating soot production in gasoline direct injection engines

Green Car Congress

Although today’s passenger vehicle engines are cleaner and more fuel efficient, GDI exhaust can still contain significant numbers of nanoscopic soot particles that are small enough to penetrate the lungs and bloodstream. This new computer model could help car makers improve their engines to cut soot formation.
