MAN Engines showcasing D3876 diesel engine for EU Stage V locomotives without exhaust after-treatment systems

Green Car Congress

One of its outstanding features is the in-line six, which meets the EU Stage V emission standard for locomotives without the need for an exhaust after-treatment system (EATS). This means that a single technical solution equally covers emission requirements for all currently recognised emissions threshold values up to EU Stage V.

UK consortium developing biogas and hydrogen dual-fuel Class 66 locomotive

Green Car Congress

The project is also supported by Network Rail, Tarmac, Rail Safety Standards Board (RSSB), Flogas, Carrickarory and the University of Birmingham. Exhaust emissions will be assessed in line with the latest RSSB guidance to understand both the baseline conditions and the impact of dual-fuelling for both hydrogen and biogas.

MAN Engines approves off-road engines for use with regenerative diesel/HVO

Green Car Congress

According to MAN Engines, all MAN off-road engines from the current product portfolio can be operated with regenerative diesel—also known as HVO (hydrogenated vegetable oil)—in accordance with the EN15940 standard in Europe or the US specification ASTM D975. Marine engines for regenerative diesel have already been approved.

MAN D3876 engine ensures high thrust and future-proofing in PistenBully 800; engine basis for possible H2 variant

Green Car Congress

This saves the operator costs and also reduces the CO 2 emissions of the engines. Equipped with the latest exhaust technologies, the MAN D3876 complies with the current and strict EU Stage V emission regulations. As a result, significant savings in fuel consumption can be achieved.

CMU study finds secondary organic aerosol production from PFI and GDI vehicles has been “substantially” reduced by tightening NMOG standards

Green Car Congress

Now, in a new study published in the ACS journal Environmental Science & Technology , researchers at Carnegie Mellon University have found that secondary organic aerosol (SOA) production from both port fuel injection (PFI) and gasoline direct injection (GDI) vehicles has been substantially reduced through the tightening of NMOG emissions.

First MAN ME-GA Otto-cycle engine completes gas trials

Green Car Congress

As its pre-mixed combustion results in low NO x emissions, the ME-GA engine is inherently Tier II and Tier III compliant in gas-operation mode. EGR as standard enables the ME-GA to significantly reduce emissions, while simultaneously improving fuel efficiency and operation in both gas and fuel-oil operation. —Thomas S.

Mercedes-Benz Buses Meet EEV Emissions Standard Without Diesel Particulate Filter

Green Car Congress

Mercedes-Benz achieved the low emissions solely by means of internal engine measures and without an additional particulate filter in the case of the Mercedes-Benz BlueTec engines or a fuel economy penalty. Additional exhaust gas aftertreatment via SCR is not necessary. Tags: Diesel Emissions Engines Heavy-duty.
