New Mercedes-AMG SL 43 features engine with electric exhaust gas turbocharger derived directly from Formula 1

Green Car Congress

liter turbocharged M139 engine featuring an electric exhaust gas turbocharger. The turbocharger is operated via the 48-volt electrical system, which also feeds the belt-driven starter-generator (RSG). An electric motor around 1.6 Under the hood of the open-top 2+2-seater is an AMG-enhanced 2.0-liter

Eaton leverages cylinder deactivation and exhaust thermal management technologies to reduce commercial vehicle emissions

Green Car Congress

To date, the technology has been evaluated with a close-coupled selective catalytic reduction (SCR) aftertreatment system with and without a 48-volt electric heater. Notably, using the same aftertreatment system with the addition of a 48-volt electric heater located upstream of the SCR further achieved a reduction in CO 2.

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.

Toyota unveils 2021 Venza crossover, hybrid powertrain standard

Green Car Congress

liter DOHC four-cylinder engine with three electric motors in a highly compact system. The gas engine employs Variable Valve Timing-intelligent system by Electric motor (VVT-iE) on the intake camshaft, and VVT-i on the exhaust camshaft. Additionally, EV mode allows electric-only driving at low speeds for short distances.
