Volkswagen announced it plans to introduce a new clean diesel engine starting next year.

The new engine, designed EA288, will make its debut in the 2015 Beetle, Golf, Jetta, and Passat in the second half of 2014.  It will eventually replace all current VW and Audi 2.0-liter diesel engines.

The new 2.0-liter four-cylinder engine is turbocharged and uses Bosch common-rail technology as well as direct injection.  It is capable of developing 150 horsepower (10 more than the current engine) and 236 pound-feet of torque.  The bore spacing is the only thing that the new powerplant has in common with its predecessor.  It will use a complex exhaust gas recirculation system (with a high pressure EGR and a cooled low-pressure EGR) and the integration of the water-cooled intercooler and EGR valve with the intake manifold is said to improve throttle response.  In addition, VW is moving the exhaust after-treatment components closer to the engine by combining the diesel particulate filter with the SCR (selective catalytic reduction) catalyst.

Other changes in the engine will minimize friction and optimize fuel economy including low-friction bearings for the camshaft and balancer shafts and a two-stage oil pump with volumetric flow regulation.

Volkswagen is currently the market leader in diesel automobile sales in the U.S. with a total of 47,000 diesel-powered cars sold in 2013 and 10,000 in July, representing over 77% of diesel passenger car sales.
