Full lifecycle CO2 of new Mercedes C-Class 10% less than outgoing model

Green Car Congress

The C 180 (115 kW) with manual transmission was taken as the base variant of the new C-Class at market launch for the lifecycle analysis; it was compared with the corresponding preceding model. Production of the new C-Class results in a higher CO 2 emissions than in the case of the predecessor (7.3 The new C-Class.

Cummins ETHOS 2.8L optimized E-85 engine demonstrates 50-80% reduction in CO2 emissions in medium-duty truck

Green Car Congress

To take full advantage of the favorable combustion attributes and potential of E-85, the engine operates at diesel-like cylinder pressures and incorporates advanced spark-ignition technology. It delivers the power (up to 250 hp / 186 kW) and peak torque (up to 450 lb-ft / 610 N·m) of gasoline and diesel engines nearly twice its 2.8-liter

U Toronto team assess the climate trade-off between reduced CO2 and increased Black Carbon from GDI engines

Green Car Congress

The upside of gasoline direct injection (GDI) engines is widely seen as being improved fuel economy coupled with an increase in specific power (especially with turbocharging), enabling significant downsizing. A significant fraction of the GDI PM 2.5 The extent of fuel-air mixing can be affected by injection system design.

CPT developing 48-volt electric supercharger for micro-mild hybrids

Green Car Congress

At 48 volts, a VTES electric supercharger will transform 7kW of battery power into a highly boosted charge of air for downsized gasoline and diesel engines. There will be no torque deficit or other tradeoffs from essential engine downsizing and higher gearing, which now dominates the development of internal combustion engines.

CPT presenting two papers at SAE World Congress on SpeedStart and TIGERS for 48V mild hybrid systems

Green Car Congress

The switched reluctance (SR) motor-based SpeedStart and TIGERS technology are being incorporated into the recently announced Advanced Diesel Electric Powertrain project known as ADEPT. As a reduced cost concept, it aims to make more intelligent use of electrical energy to achieve the desired reduction in fuel consumption and CO2 emissions.

Renault 2010 Environment Workshop, Part 1: Combustion Engine Technology and Product Plans

Green Car Congress

Renault’s ongoing downsizing strategy is aimed at reducing the cubic capacity of its engines in order to bring down fuel consumption and CO 2 emissions, without detracting from performance. dCi (type K9K) diesel is the brand’s best-selling engine with almost 900,000 units manufactured in 2009, in Valladolid (Spain) and Bursa (Turkey).

Electric cars still ‘twenty years away’ say Mercedes

Green Cars News

All-electric cars with the range of modern day petrol or diesel-equipped engines are still 20 years away, says Mercedes-Benz research and development boss Thomas Weber. Weber said that there are still many gains to be made in terms of fuel consumption and CO2 reduction with existing engines and transmissions.
