Volkswagen’s new diesel engine cleaner, more powerful

volkswagen-ea288-1

Starting with the 2015 model year Volkswagens in the US, the company will be rolling out a new generation 2.0 clean diesel engine dubbed EA288. The new engine while the same size as the current 2.0 liter will offer 10 more horsepower, but cleaner emissions.

The company announced this officially this week during a speech at the Management Briefing Seminars in Traverse City, MI. The new engine will power the 2015 Golf, Beetle, Passat, and Jetta, all of which due in showrooms in the second half of 2014.

The new EA288 diesel will eventually replace all the 2.0-liter TDI engines sold in Audi and Volkswagen TDI models in the States. Like the current engine, the EA288 turbocharged with a common-rail, direct-injection system.


Making 150 horsepower and 236 pound-feet of torque, the engine is all new despite being the same size as the current powerplant. Volkswagen says it only shares bore spacing with the current diesel engine.

To reduce emissions, the EA288 has a complex exhaust gas recirculation system with high pressure EGR and a cooled low-pressure EGR. An integrated air to water intercooler is built into the manifold which reduces under hood complexity as well.

All this direct packaging also improves throttle response by reducing the length of the intake charge path. Packaging the exhaust after-treatment components close to the engine also increases its cleanliness, combining the DPF with the SCR Catalyst.

The engine also has a number of modifications to help minimize friction such as low-friction bearings for the camshaft and balance shafts and piston rings that have less pre-tension. There is also a two-stage oil pump which takes less of the engines power to operate.

There is no question that Volkswagen intends to stay on top of the diesel market in the United States. This year, they have sold more than 47,000 diesel vehicles. This represents nearly 78 percent of the diesel sales for passenger cars in the United States.
