In a new study, a team from UCLA, with colleagues from the California Air Resources Board (ARB) and West Virginia University, measured total particle number emission factors (PNEFs) from six newly certified heavy-duty vehicles (HDVs) powered by diesel and CNG totaling over 6,800 miles of on-road operation in California. g/bhp-hr NO x FEL.

These new standards are to include standards for newly manufactured locomotives (which ARB refers to as “Tier 5”), and a new standard for Tier 4 locomotives upon remanufacture. he new Tier 3 PM emission standards went into effect for engine model years 2012-2014 for line haul locomotives and represented a minor step change.

The 2014 Canter meets the requirements of different emissions standards, depending on the weight variant. Up to a reference mass of 2380 kg, the complete vehicle has its emission characteristics tested on a chassis dynamometer, with the result being shown in pollutants per km.

These will equip its trucks when the new standard becomes compulsory in January 2014 (January 2013 for new homologations). This recycles part of the exhaust gases during combustion and reduces the amount of NO x produced by the engine. Click to enlarge. The 5 and 8 L Euro VI engines are fitted with an EGR system.

Neste, currently largest producer of renewable drop-in fuels (primarily diesel) with its NEXBTL platform ( earlier post ), has filed a patent ( US20150144087 ) on a gasoline composition (and the method for making it) comprising up to 20 vol% (preferably from about 10-15 vol.%), of paraffinic bio-hydrocarbons originating from the NEXBTL process.

Low temperature combustion (LTC) refers to a broad range of in-cylinder combustion strategies for the reduction of NO x emissions from diesel combustion; NO x is formed primarily by a thermal mechanism, which production rates increasing exponentially with temperature. One common technique is to place the main injection near TDC.

This latest work, presented at SAE 2014 World Congress, shows that moving to higher compression ratios (CR) and lower fuel cetane numbers (DCN) from an SI base engine offers a better trade-off than increasing DCN with a lower CR. Demand growth is expected to skew toward commercial transport, which uses heavier fuels such as diesel and jet.

With the introduction of the stringent Tier 4A emissions regulations (also referred to as Tier 4 interim), PM will be reduced by a further 90% and NO x by 50% over Tier 3 levels. New Holland will use SCR technology to reach the even more stringent Tier 4B emissions norms which will be phased in from 2014 onwards for the entire product range.
