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.

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

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.

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.

Groundbreaking research in the last 10 years has identified combustion engine strategies that—especially if optimized to run on new fuels—would offer significantly higher efficiency and produce fewer engine-out pollutants than current engines. Fuel research will focus on low-GHG advanced biofuel/petroleum blends.

Thrust 1 builds on the significant amount of work carried out over the past several decades, focused on building advanced boosted, downsized, and downspeeded spark ignition engines. High combustion noise and high HC and CO emissions are also a problem, with lower exhaust temperatures representing a challenge for current emissions controls.

That front-drive mode gets the car a green light in cities like London and Rome as they begin to bar polluting cars from their downtown areas. Automakers are finding it difficult to challenge those boldface numbers with internal combustion alone, especially as engines are relentlessly downsized to meet regulations.

This means that in addition the power demand is more difficult to achieve with engine downsizing and transmission down-speeding alone. The EU goal is to introduce the WLTP by 2017 if possible and no later than 2020 to coincide with the 95 g/km requirement. The WLTP is significantly more dynamic with faster acceleration rates.

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.)
