Oliver Schmidt, General Manager, Energy and Environmental Office, Volkswagen Group of America confirmed that the new EA288 diesel engine will power the 2015 Golf, Beetle, Passat, Jetta, which are due in dealer showrooms in the second half of 2014. The new EA288 will eventually replace all the 2.0-liter TDI Clean Diesel engines fitted in Audi and Volkswagen TDI Clean Diesel models. Schmidt made the announcement during a speech delivered at the Management Briefing Seminars in Traverse City, Mich.

The EA288 is part of Volkswagen’s MQB transverse assembly toolkit, and is also applied in the Golf GTD heading for the US (earlier post). In the MQB set, the new EA288 four-cylinder covers engine displacements ranging from 1.6 to 2.0 liters.

Volkswagen Group of America said the announcement underscored the Group’s continued success with diesel technology in the US—year-to-date the Volkswagen Group of America has sold more than 47,000 clean diesel vehicles, including more than 10,000 in the month of July alone. This represents nearly 78% of the diesel sales for passenger cars in the United States this year.

The engine is a turbocharged, common-rail, direct-injection four-cylinder engine delivering 150 hp (112 kW)—an increase of 10 hp over the current engine—and 236 lb-ft (320 N·m) of torque.

This engine shares only the bore spacing with the previous diesel engine that shared the same designation. A number of changes have been made to help reduce emissions, such as:

  • use of a dual-loop exhaust gas recirculation (EGR) system (with high pressure EGR and a cooled low-pressure EGR);

  • integration of the water-cooled intercooler and the EGR valve with the intake manifold, which also improves throttle response; and

  • packaging the exhaust after-treatment components close to the engine by combining the DPF with the SCR Catalyst.

The engine also has a number of modifications to help minimize friction and optimize fuel economy: there are low-friction bearings for the camshaft and balancer shafts; piston rings that have less pre-tension; and the oil pump is a two-stage device with volumetric flow regulation.
