The increasingly stringent emission regulations, such as US 2010, Tier 2 Bin 5 and beyond,
off-road Tier 4 final, and Euro V/5 for particulate matter (PM) reduction applications, will …

The high-pressure SCR system is suitable for low-speed marine engines that burn high-
sulfur fuel, but it will cause the increase of the exhaust back pressure of main engine, which …

Alternative fuels reduce the carbon footprint of internal combustion engines. Biofuels are the
most important alternative fuels. Manufacturing processes for biofuels have made it possible …

The development of highly efficient engines with lower exhaust gas temperatures leads to
new challenges for catalysts in the aftertreatment system. One option for overcoming this is a …

Worldwide emission regulations are driven the efforts of the automotive industry to meet
challenging targets concerning pollution reduction. Nowadays, advances in exhaust …

As well as new advances in the after-treatment systems are required to achieve the new
pollutant emission requirements, new designs of the exhaust line can be considered in order …

In the current work a computational study to evaluate the effect of the DPF downsizing on
filtration efficiency is performed. The DPF is conventionally placed downstream of the …

Growing interest has arisen to adopt Variable Valve Timing (VVT) technology for automotive
engines due to the need to fulfill the pollutant emission regulations. Several VVT strategies …

Wall-flow particulate filters are in the present days a standard aftertreatment system widely
used in diesel engines to reduce particle emissions and meet emission regulations. This …
