IAV develops new close-coupled diesel exhaust gas aftertreatment system for improved emissions reduction

Green Car Congress

IAV has developed a particularly closed-coupled diesel exhaust gas aftertreatment (EAT) system. A key contribution to this performance must come from the exhaust gas aftertreatment system—across the entire speed and load range. This way, exhaust gas flows through DOC and SCRF before it enters the turbine.

Cadillac's New Electric V-Series Concept is Far From a Silent EV

The Truth About Cars

It was easy to make fun of Dodge and the “fake” exhaust it chose to employ on the new Charger EV, but it’s no longer the only one trying to capture the thrill of a performance gas engine with a silent electric powertrain underneath. That said, GM hasn’t had the smoothest rollout with its other electric models.

Stena Line seeking novel approaches to recover energy from exhaust gases from ship engines

Green Car Congress

Stena Line is seeking novel, cost-effective approaches to recover energy from exhaust gases from ship engines and to transform it into a more useful energy form (e.g., electricity to supply hotel loads on board the ship). These energy losses are primarily radiant heat loss and the sensible heat of exhaust gases.

Westport and Scania preliminary testing shows H? HPDI delivers peak BTE of 51.5% at mid-load

Green Car Congress

Westport’s HPDI fuel system technology enables heavy-duty trucks to operate on natural gas with the same power, torque, efficiency, and performance as diesel engines. Scania’s engine fulfils the strictest exhaust emission requirements with low fuel consumption and high torque. H2 HPDI operates the system with hydrogen. —David M.

Dodge unveils concept electric muscle car

Teslarati

Dodge has unveiled its new concept electric muscle car. It’s powered by “banshees,” equipped with the world’s loudest EV exhaust note, and it’s 100% pure Dodge. Is Dodge too late to the electric vehicle market? The post Dodge unveils concept electric muscle car appeared first on TESLARATI.

Porsche simulates hydrogen V8 for virtual Nordschleife run; 440 kW, 261 km/h, near-zero NOx

Green Car Congress

We have therefore developed a hydrogen combustion engine that aims to match the power and torque of current high-performance gasoline engines as a concept study. On the other hand, however, the lower exhaust gas temperatures result in a lack of energy for their propulsion on the exhaust side. —Vincenzo Bevilacqua.
