NASA and DLR to conduct joint flight tests on alternative fuel emissions with focus on ice crystals

Green Car Congress

The focus will be on alternative fuel emissions and the characterisation of ice crystals in condensation trails (contrails), using biofuel as an example. The joint research flight campaign has been given the title ND-MAX/ECLIF 2 (NASA/DLR-Multidisciplinary Airborne eXperiments/Emission and CLimate Impact of alternative Fuel).

DNV GL paper suggests near-term success for LNG in shipping; alternative fuel mix to diversify over time

Green Car Congress

Well-to-Propeller GHG emissions results for marine alternative fuels. DNV GL has released a position paper on the future alternative fuel mix for global shipping. The global merchant fleet currently consumes around 330 million tonnes of fuel annually, 80-85 per cent of which is residual fuel with high sulfur content.

DLR wrapping up ECLIF in-flight study of emissions from alternative aviation fuels; potential for improved fuel design

Green Car Congress

In a three-week series of flight tests lasting until 9 October 2015, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) has been investigating how to reduce the impact of air transport on the climate by using alternative fuels. At present, global air traffic contributes towards almost 5% of global warming.

NASA begins ACCESS flight research to study effects of biojet fuels on engine performance, emissions and contrails

Green Car Congress

NASA researchers have begun a series of flights using the agency’s DC-8 flying laboratory to study the effects of alternate biofuel on engine performance, emissions and aircraft-generated contrails at altitude. Survey black carbon and gas-phase emissions and contrail properties from commercial aircraft at cruise in air-traffic corridors.

Pi Innovo introducing new M670 rapid prototyping ECU

Green Car Congress

The M670 is a 154-pin high feature engine controller designed to support gasoline PFI, GDI, diesel solenoid, and alternative fuel applications. The ECU supports a broad range of engine control features such as dual ETC, quad VVT, VGT, dual knock, UEGO (Universal Exhaust Gas Oxygen), HEGO (Heated Exhaust Gas Oxygen), and more.

CPT launching water-cooled electric supercharger for commercial diesel engines

Green Car Congress

Cobra could enable a 5–10% reduction in CO 2 emissions when implemented in conjunction with engine downsizing and down speeding strategies, and potentially more when used in conjunction with alternative fuels, according to CPT. Unlike a turbocharger, Cobra is not dependent on the exhaust gases flowing to do its work.
