Volkswagen 2.0 TDI diesel for Euro 6d; SCR twin-dosing

Green Car Congress

With SCR twin dosing technology in the exhaust gas system, the diesel unit now undercuts the Euro 6d emission standard limits while also running quietly and smoothly, according to the company. The four-cylinder TDI engine with the internal designation EA 288 made its debut in 2012. As previously, the 2.0

ORNL-led team developing breakthrough high-temperature, high-strength Al alloy for advanced light-duty engines

Green Car Congress

The work, led by Dr. Amit Shyam at ORNL, is part of a 4-year project consisting of a CRADA partnership with FCA and foundry giant Nemak. Projected conditions for internal combustion engines in 2025 push light-duty engine exhaust temperatures into the low end of gas turbine regimes, Haynes said. Earlier post.).

This is done by changing the locations of intake and exhaust ports asymmetrically which allows for the extraction of more energy during the expansion stroke. Three combustion events per rotor revolution result in high power density. Water may be injected to internally cool the engine. Shkolnik et al. 2014) Click to enlarge.

Behind Audi’s new “rightsized” efficient EA888 Gen.3B family

Green Car Congress

The new Audi engine combines shorter intake events with a high geometric compression ratio; together with other refinements to the basic engine, the new combustion concept enables a reduction in combined cycle CO 2 emissions of up to 10-12 g/km compared to its predecessor. Audi says that the new 2.0L 3B designation. The basic Gen.3B
