Ford Unveils 6.7-Liter Power Stroke Engine Compatible with B20
January 8, 2010
The Ford Motor Company has announced an new 6.7-liter Power Stroke V-8 turbocharged diesel engine that is compatible with biodiesel up to B20 (20% biodiesel, 80% petroleum diesel). The new diesel engine will debut in the 2011 Ford F-Series Super Duty pickup and is expected to deliver significant improvement in torque, horsepower, and fuel economy.
The diesel engine team made improvements and changes throughout the engine architecture to deliver aggressive horsepower, torque, emissions, and fuel economy targets. The 6.7-liter Power Stroke uses an "inboard exhaust" architecture, an automotive-industry first for a modern production diesel engine. The inboard exhaust and outboard intake architecture, a first for a modern production diesel engine, reduces overall exhaust system volume, which leads to better throttle response for the customer.
