2010 engines emissions reduction relative to 2010, 2007, and 2004 US emission standards. earlier post ), found that emissions of NO 2 and other nitrogen oxides—which can have direct health effects and contribute to the formation of smog—were approximately 61% below the 2010 EPA standard and 99% lower than in 2004 engines.

A team from the California Air Resources Board (ARB) reports on their evaluation of the in-use emissions performance of four different heavy-duty diesel engines certified to the MY 2010 or interim MY 2010 NO x standards over a wide range of driving conditions in California in a paper published in the ACS journal Environmental Science & Technology.

Mazda Motor Corporation has launched the fully updated the Mazda Carol micro-mini for the Japanese market, its first full remodeling since September 2004. Exhaust emissions are at least 75% lower than Japan’s 2005 standards. The most fuel-efficient versions in the range, the front-wheel drive (FWD) grades with CVT, achieves 24.5

The smaller size enables better heat management and retention for improved fuel economy capability, while the simple single-pass exhaust flow design delivers low back pressure, meeting the needs of end-user customers. Since 2004, more than 1 million EcoFit DPFs have been put into use.

Our goal is to enable hyper-efficient hybrid vehicles to meet consumer needs for a 500-mile driving range, lower vehicle prices, full-size utility, improved highway performance and very low operating costs. In axial-flow configurations, noted Müller and co-authors in a 2004 paper, pure scavenging is a challenging task. Piechna et al.

In the early 1990s, Fairbanks Morse Engine introduced dual-fuel combustion technology that reduced NO x exhaust emissions to levels previously achievable with only lean-burn spark-ignited gas engines. Achates Power began modernizing opposed-piston engines in 2004, inspired by the record-setting Junkers Jumo 205 diesel aircraft engine.

For instance, intake/compression, combustion, expansion/exhaust are occurring simultaneously in separate chambers. Combining the high peak pressures produced during constant volume combustion with Atkinson expansion, which continuously extracts energy as exhaust gases expand to atmospheric pressure, delivers unprecedented fuel efficiency.
