Downsizing, Exhaust, Gas and Pollution

NREL announces $18M investment in 9 new projects to advance medium- and heavy-duty natural gas vehicle technologies

Green Car Congress

MARCH 7, 2019

The selected projects will focus on reducing the total cost of ownership of NGVs, increasing vehicle efficiency, decreasing local air pollution, and advancing technology development to increase the use of more affordable medium- and heavy-duty natural gas engines and vehicles. Cummins Inc.

It is important to state that there are several technology paths to achieve these levels of emissions, and some of them can simultaneously lower greenhouse gas emissions, such that the NO x reductions do not compete with the CO 2 reductions.

The PureTech engines offer equivalent or better power compared with the previous generation powerplants, combined with significantly lower fuel consumption and greenhouse gas emissions, down by roughly 25%. To achieve these results, PureTech development called for a number of changes, chief among which were: Downsizing. liter and 1.2

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.

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.

AUGUST 1, 2016

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.

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.
