Description:

22 June 2021: While the use of renewable energy has increased, fossil fuels remain a dominant source of energy for the world, according to the Renewables 2021 Global Status Report by REN21. In relative terms, renewables grew almost 5% per year between 2009 and 2019, outpacing fossil fuels (1.7%). But in absolute terms, coal, oil, and natural gas satisfied some 75% of the global energy demand growth over the decade [more...]15 June 2021: CIMAC has announced a Call for Papers for the 2022 CIMAC Congress. Next year in Busan, South Korea, the Congress will be held for the 30th time [more...]10 June 2021: Updated Technology Guide paper on Crankcase Ventilation—added more discussion on turbocharger impacts of closed crankcase ventilation.9 June 2021: It is time to register for the Integer Vehicle Emissions Live virtual conference that will be held on June 15-17. Organized by Argus Media, the conference will explore key opportunities to enhance the diesel engine and meet new emission standards, as well as the market trends for AdBlue/DEF. The program includes talks by leading fuel, engine, and vehicle OEMs, as well as updates from regulatory authorities in the USA, UK, and India.

The pathway to reach net-zero GHG emissions by 2050 “remains narrow and extremely challenging”—it contains no new oil and gas fields approved for development, and no new coal mines or mine extensions beyond those that have already been committed to. By 2050, coal consumption would have to fall by 90%, oil by 75%, and natural gas by 55%. The report also envisions that the transition to a net zero energy system by 2050 could be accompanied by “robust economic growth”. Considering that our industrial economy is powered in more than 80% by fossil fuel energy, this plan is indeed very challenging, to say the least. The report reflects a sharp change in course by the IEA—in the past, the agency had issued a number of stark warnings that the global energy investment was falling short of what would be needed to meet future global energy demand.5 May 2021: The International Energy Agency released a special report that examines the central importance of minerals such as copper, lithium, nickel, cobalt and rare earth elements in a secure and rapid transformation of the global energy sector [more...]30 April 2021: For your reading pleasure, a summary of engine and emission sessions from that SAE WCX 2021 Digital Summit held on April 12-15, 2021 [more...]20 April 2021: The IEA expects the global GDP to increase by 6% in 2021 relative to 2020 and by more than 2% relative to 2019. This level of economic activity will require a steep increase in energy demand, causing a sharp growth in CO2 emissions [more...]13 April 2021: CIMAC announced their first Tech-Talk web event on the topic The Value of Digitalization in the Maritime Industry on Thursday, April 22, 2021 between 14:00-15:00 CEST. The event is organized by the CIMAC Digitalization Strategy Group. More details regarding the Tech-Talk and a registration link are available on the CIMAC website.9 April 2021: Presentations from the 11th VERT Forum are now available online. The Forum, held online on March 25th, discussed technologies and policies towards zero-impact combustion engines, and reviewed emission reduction initiatives and programs spearheaded by the VERT Association in many countries around the world.8 April 2021: The three regions of Belgium—the Flemish and Walloon Regions and the Brussels-Capital Region—have reached an agreement to implement a particle number test during the annual vehicle inspection of diesel cars (PTI-PN), to detect tampering with diesel particulate filters [more...]7 April 2021: Emission standards—Added summaries of California zero emission vehicle (ZEV) programs for light-duty vehicles and for heavy-duty trucks.25 March 2021: Emission standards—Updated summary of US emission standards for heavy-duty engines covers the California low NOx regulation that becomes effective in 2024/2027.24 March 2021: The Poland’s Motor Transport Institute (ITS)—now on DieselNet—is a provider of R D services in the area of air pollution from road transport with a wide range of automotive testing capabilities, from type approval, ISC and RDE emission tests, to aftertreatment and other component testing.23 March 2021: Cambustion announced a portable version of their fast CLD NOx analyzer, which can be used for engine exhaust measurements (T10-90% = 15 ms), as well as for ambient measurements down to 5 ppb (100 ms). Examples of engine-out and air-quality measurements are illustrated by videos [more...]22 March 2021: New sections discussing the cost of emission control components have been added in two Technology Guide papers: Engine Emission Control and Emission Control from In-Use Engines.16 March 2021: The semiconductor shortage faced by the global automotive industry may continue for several months. ACEA wrote a letter to the European Commission, to draw attention to the seriousness of the problem. “(The shortage of semiconductors) has led to partial or complete production stoppages in motor vehicle manufacturing plants in Europe and elsewhere,” ACEA said in the letter. “Everything indicates that this shortage will persist for many months, possibly into the third quarter of this year. As a result, production volumes in Europe will probably be considerably lower than expected this year.” The European auto industry calls up on the European Commission to talk to the government of Taiwan, the host to some major semiconductor producers, to obtain additional supplies of semiconductors, to ensure EU auto makers are not put at a disadvantage vis‐à‐vis their US or Asian competitors.9 March 2021: Switching to “sustainable aviation fuels” (SAF) is sometimes envisioned as a key approach to achieve various decarbonization targets faced by the aviation industry. A new working paper by the ICCT examines the SAF feedstock resource base and the aviation fuel demand in the European Union, putting a dose of reality on the concept. The analysis concludes that the available waste fat, oil, and grease feedstock resources would allow to displace about 2% of the EU jet fuel demand with SAF by 2030. Moving beyond 2% of SAF deployment would require targeted support for more conversion pathways with “more challenging economics and uncertain production timelines”, such as lignocellulosic biofuels and electrofuels. In the “optimistic deployment” scenario that includes these novel technologies, the EU resource base could support 3.4 million tonnes of advanced SAF production annually, or 5.5% of projected EU jet fuel demand in 2030.The diesel engine is the most efficient power plant among all known types of internal combustion engines. Heavy trucks, urban buses, and industrial equipment are powered almost exclusively by diesel engines all over the world. For the foreseeable future, the world’s transportation needs will continue to rely on the diesel engine and its gasoline counterpart. However, both engine technologies have been evolving to meet two major challenges: lower emissions and increased energy efficiency.Internal combustion engines are significant contributors to air pollution. In response, clean diesel technologies with near-zero emissions of NOx and PM have been developed and introduced in regions with the most stringent emission standards. As this trend spreads to other parts of the world, the environmental focus has shifted to climate changing emissions and energy efficiency. The environmental benefit of low greenhouse gas emissions, traditionally associated with the diesel engine, is no longer sufficient. To meet future greenhouse gas and fuel economy regulations, new technologies are being developed—low temperature combustion, waste heat recovery, powertrain electrification, to name a few—that further increase the efficiency not only of the diesel engine powertrain but the entire vehicle as well. Under low-carbon regulatory policies, the scope for potential improvements is no longer limited to engines and vehicles, but also includes life cycle effects of fuel production and vehicle manufacture.DieselNet, the only information service exclusively devoted to internal combustion engines and emissions, is an internet knowledge base for technical and business information on diesel engines, fuels, emissions and technologies required by the clean and efficient diesel engines of the future.Home
