MECA report assesses technology feasibility for heavy-duty diesel trucks to meet lower NOx standards by 2024

Green Car Congress

g/bhp-hr in low load operation using the proposed low load certification cycle being developed at Southwest Research Institute under a contract from the California Air Resources Board (CARB). The technologies outlined are either commercial or market-ready options that can be deployed on vehicles by model year 2024 to achieve 0.05

CPT presenting two papers at SAE World Congress on SpeedStart and TIGERS for 48V mild hybrid systems

Green Car Congress

Within the SpeedStart design water-cooled power and control electronics are housed within the rear of the machine to reduce cost, improve control response times and minimise losses in the power electronics. The exhaust gas can reach temperatures greater than 900 °C, whereas the turbine upper functional limit is 850 °C.

Optimizing a CNG-Fueled Spark Injection Engine for a Parallel Hybrid Powertrain

Green Car Congress

In recent years two methods, namely downsizing and downspeeding, were established on the market to reduce CO 2 emissions while maintaining the driving performance of engines with identical effective power but a larger displacement. bar) is achieved by applying high- or low-pressure exhaust-gas recirculation loops. < IMEP < 22.5

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

Green Car Congress

Due to the continued exposure of millions of Americans to poor air quality, both the United States Environmental Protection Agency (EPA) and California Air Resources Board (CARB) have announced rulemakings focused on revising the heavy-duty truck emission standards, with a particular focus on tighter limits for oxides of nitrogen (NO x ).

Daimler Trucks NA SuperTruck achieves 115% freight efficiency improvement over 2009 baseline; 50.2% engine BTE

Green Car Congress

The Freightliner SuperTruck uses a downsized and downsped 10.7-liter Friction-reducing measures include a variable speed water pump, a clutched air compressor, low-viscosity oil and an improved cylinder kit. The aftertreatment system features additional insulation to retain maximum heat energy in the exhaust. Click to enlarge.

Viable exhaust-driven on-board ethanol reforming for improvements in fuel economy and emissions

Green Car Congress

A team at Monsanto and colleagues at AVL Powertrain have successfully designed and demonstrated an onboard low-temperature ethanol reformer that can be driven by exhaust heat. Many papers have described high-temperature steam reforming of ethanol at around 600 °C but.this temperature is too high to be driven by engine exhaust.
