Study finds catalyzed gasoline particulate filters effective at reducing particulate and PAH emissions from GDI engines

Green Car Congress

The researchers assessed the gaseous, particulate, and genotoxic pollutants from two current technology gasoline direct injection vehicles when tested in their original configuration and with a catalyzed gasoline particulate filter (GPF). liter downsized turbocharged centrally-mounted direct injection engine. Yang et al.

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. The cO 2 emission factor was calculated assuming a fuel carbon content of 8887 g/gallon. mpg (10.99

Dearman begins on-vehicle testing of Gen 2 transport refrigeration system powered by liquid air engine; lighter, more efficient

Green Car Congress

The Dearman liquid air engine is an innovative heat engine that uses liquid air (or liquid nitrogen) as a “fuel” and emits cold air as exhaust. After each expansion cycle the heat exchange fluid is recovered from the exhaust and reheated to ambient temperature via a heat exchanger similar to a conventional radiator. Earlier post.)

Use of Supercritical Diesel Fuel for Improved Efficiency and Reduced Emissions

Green Car Congress

Heat required to bring the fuel to SC states is recovered from the exhaust gas of the engine. To attenuate that risk, the researchers use a diluent such as CO 2 , H 2 O or exhaust gas. George Anitescu from Syracuse presented the work in a poster at the DEER 2009 conference in Dearbon, Michigan. At SC conditions, however (T?450

Citroën introduces first members of new 3-cylinder gasoline engine family; 1.0L and 1.2L PureTech reduce fuel consumption about 25%

Green Car Congress

To achieve these results, PureTech development called for a number of changes, chief among which were: Downsizing. The exhaust manifold is integrated directly in the cylinder head, which reduces the number of parts and overall weight. The specifications also stipulated a specific power of 50 kW per liter. Three cylinders.

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. The downsizing process involved shortening the piston stroke by reducing the size of the crank pin and conrod assembly. Select Engines.

Specific to diesel, it also has the potential to significantly reduce pollutant emissions, like mononitrogen oxide (NO x ), and help meet more stringent regulations including the Real-Driving Emissions test in Europe. Regional highlights include: In North America, more engine downsizing is expected. liter six-cylinder.
