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 extent of fuel-air mixing can be affected by injection system design. Credit: ACS, Zimmerman et al.

MECA report finds additional NOx emission reductions from new heavy-duty trucks achievable and cost-effective

Green Car Congress

New substrates are designed with thinner walls or higher porosity, which allows the coating of better catalysts without sacrificing durability. This has resulted in higher catalyst loading per volume of substrate and led to downsizing of systems from those available in 2010. —MECA Executive Director, Rasto Brezny.

Honeywell Transportation Systems Forecast: turbocharged vehicles to account for 48% of annual global sales by 2021; electric boosting emerges

Green Car Congress

By rightsizing engines with available technologies, automakers are able to continue applying the benefits of smaller turbocharged engines while fine-tuning powertrain systems to further optimize fuel economy, emissions and performance. Regional highlights include: In North America, more engine downsizing is expected.

Ricardo and Growth Energy Collaborate On First Vehicle-Based Demonstration of Ricardos Ethanol Boosted Direct Injection (EBDI) Engine Technology

Green Car Congress

Based on test work already carried out, Ricardo estimates that a fuel economy improvement of up to 30% is possible with no loss of power or performance, using a downsized EBDI engine in place of currently available gasoline powertrain technology. fuel economy improvement. Ricardo is replacing a 6.6-liter

Fiat Introduces Multiair Electro-Hydraulic Valve-Timing System

Green Car Congress

Fiat expects that Multiair, with direct control of the air through the intake engine valves without using the throttle, can help reduce fuel consumption by up to 10% for turbocharged or naturally aspirated gasoline engines. Pollutant emissions are likewise reduced through combustion control.
