Achates OPGCI project targeting 50% fuel efficiency gains over downsized GDI engine at reduced cost

Green Car Congress

The engine should yield fuel efficiency gains of more than 50% compared to a downsized, turbo-charged gasoline direct injection engine, while reducing the overall cost of the powertrain system, said Fabien Redon, Vice President, Technology Development at Achates Power.

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.

Study finds fleet switch from PFI to GDI engines will result in net reduction in global warming

Green Car Congress

Although real-world fuel economy improvements from GDI technology alone are close to 1.5%, they can reach 8% by downsizing and turbocharging the engine, which can be achieved on GDI engines without loss of power compared to PFI engines. Organic gas emissions were the most sensitive to cold-start compared to the other pollutants tested.

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.)

ICCT: 2025 target average of 70 g/km CO2 for new cars in EU feasible and economical; more so with electric drive

Green Car Congress

However, although a CO 2 target of 70 g/km could be met without significant deployment of electric vehicles, the study found that exhausting all the potential gains from combustion engine technology improvements before transitioning to electric drive would be a relatively costly approach for vehicle manufacturers.
