Ford Engine News! GTDi on the way

"Ford Motor Company recently announced they would be changing over from larger, naturally aspirated engines to smaller ones using single or twin turbochargers and intercooling systems with direct fuel injection. In Ford speak, that’s Gasoline Turbocharged Direct injection (GTDi).

In direct fuel injection engines, the fuel is shot under high pressure directly into each cylinder’s combustion chamber by an injector positioned near the spark plug. In contrast, many of today’s systems the fuel is injected into the intake tract behind the intake valves. Direct injection allows for a cooler charge, more compression and more boost than port-injection. Ford is working with Honeywell turbocharging systems and integrated electronics that control fuel injection, boost, and engine electronics including ignition and valve timing.

Ford’s executive vice president for product development, Derrick Kuzak, told PM that the GTDi engines will have improved throttle response compared to earlier turbocharged engines, and would generally use both more boost pressure and higher compression ratios than the current generation of turbo engines.

Kuzak says these engines represent a potential 10 to 20 percent improvement in fuel economy. The torque curves are said to be flat over 90 percent of the rev range. He compared the torque, power and fuel economy of a potential Ford GTDi V-6 engine to the current output of a Ford 5.4-liter truck engine and that it would serve up enough grunt to pull a loaded pickup truck up a long hill.

A 3.5-liter GTDi engine will be coming in the Ford Flex midsize utility vehicle, and that the 2009 Lincoln MKS luxury sedan would have a similar engine producing 340 hp and 340 lb.-ft. of torque.

For lighter applications, Kuzak compared the performance of a potential 2.0-liter GTDi 4-cylinder engine to that of a current 3.0-liter V-6 engine, saying that such an engine would deliver up to a five mile per gallon fuel economy improvement, with more torque, too.

Kuzak says the payback period, where the savings from better fuel economy overcome the higher price paid for the engine, would be about 2.5 years for a GTDi engine, compared to 7.5 years for a diesel engine and 11.5 years for a hybrid, based on 15,000 miles per year. He said that Ford’s future GTDi engines would achieve CO2 output improvements between seven and 15 percent. Ford will eventually produce 500,000 of these new engines over the next five years. —Jim McCraw"
