I've been reading about the Duratec V6. The bottom end is cast with the Cosworth pressurized casting process. Also it has two inlet valves per cylender. One runner feeds each intake valve: a long runner for the primary intake valve to ensure torque, and a short runner for the secondary valve to provide large volumes of air at higher rpm. Only the primary intake valves are fed at all times. Placed above each secondary valve is a 34mm butterfly port throttle. At lower rpm, the port throttles are closed, thus blocking airflow to the secondary intake valves. With only one valve feeding each combustion chamber at low rpm, airflow velocities are higher, which improves low-end torque as well as exhaust emissions. How aggressively the driver is using the throttle is read by the engine's EEC-V computer. Under light-throttle conditions, like those used in around-town driving, the secondaries open at 3,900rpm, to ensure ample low-end torque. With the throttle wide open, as when accelerating to merge with traffic, the secondaries open at 3,400rpm. In either mode, from the time the secondaries open until the redline of 6,750rpm is reached, this design delivers exceptional air flow through the secondary intake valves.
Very neat eh? Also the radiator core that is 14mm deeper than that of the Contour SE
and mounted on the side of the engine block is a oil-water oil cooler
I like this car, very well built from what I can see.
