MAN ES reports Tier III exhaust-after-treatment orders for low-speed engines pass 1,000

Green Car Congress

Approximately one-quarter of the orders have been for EGR (Exhaust Gas Recirculation) systems, with SCR (Selective Catalytic Reduction) systems accounting for the remainder. The milestone was passed in early January 2021 and is built upon references from the company’s portfolio of ME-B, ME-C and MC-C fuel-oil engines.

The importance of considering non-exhaust traffic emissions; the role of EVs

Green Car Congress

the criteria pollutants and CO 2 that emerge with the exhaust from the tailpipe. However, there is more than 15 years of research showing that the contribution of non-exhaust primary particles to the total traffic generated primary particles is significant in urban areas. Further, a 2013 review by Denier van der Gon et al. Background.

Effect of syngas composition on combustion and exhaust emission characteristics in a dual-fuel engine operated in PREMIER combustion mode

Green Car Congress

Researchers at Okayama University (Japan) found that conventional combustion in a pilot-ignited, supercharged duel-fuel engine powered with different types of syngas at various equivalence ratios can be transformed into combustion with two-stage heat release.

Study identifies combustion-derived nanoparticles in diesel exhaust as the predominant mediator for adverse cardiovascular events

Green Car Congress

A European study lead by scientists at the University of Edinburgh (UK) has found that the combustion-derived ultrafine particles from diesel fuel are the predominant mediators of the adverse effects—harming blood vessels and increasing the chances of blood clots forming in arteries, leading to a heart attack or stroke.

New mixed-oxide catalysts shown as viable substitute for platinum catalysts for diesel exhaust aftertreatment

Green Car Congress

Under laboratory-simulated diesel exhaust conditions, this mixed-phase oxide material was superior to Pt in terms of cost, thermal durability, and catalytic activity for NO oxidation. Diesel engines are attractive because of their higher fuel efficiency than gasoline engines.

SwRI simulations show turbocharged Scuderi Engine could reduce a standard 2011 Nissan Sentras fuel consumption by up to 35% on FTP cycle

Green Car Congress

Modelled results of fuel consumption in 2011 Nissan Sentra. Preliminary results showed up to a 25% decrease in fuel consumption (i.e., up to 33% increase in MPG) was achievable with an SSC engine replacing the Sentra’s engine when factoring in fuel cutoff during deceleration and idle in the model.
