The 6.7L Power Stroke debuted in the 2011 Ford Super Duty (F-250 through F-550) trucks, replacing the 6.4L Power Stroke. The first Power Stroke engine to be developed and manufactured by Ford, it was designed in conjunction with AVL of Austria. [13]
In a diesel, the sensor will control the fuel injection. The sensor output may also be related to other sensor data including the cam position to derive the current combustion cycle, this is very important for the starting of a four-stroke engine. Sometimes, the sensor may become burnt or worn out - or just die of old age at high mileage.
For twin-cam or DOHC engines, VCT was used on either the intake or exhaust camshaft. (Engines that have VCT on both camshafts are now designated as Ti-VCT.↓) The use of variable camshaft timing on the exhaust camshaft is for improved emissions, and vehicles with VCT on the exhaust camshaft do not require exhaust gas recirculation (EGR) as retarding the exhaust cam timing achieves the same ...
In a piston engine, either a timing belt (also called a cambelt) or timing chain or set of timing gears is a perishable component used to synchronize the rotation of the crankshaft and the camshaft. This synchronisation ensures that the engine's valves open and close at the correct times in relation to the position of the pistons.
The engines share the same bore/stroke ratio, with the V6 version displacing 2.7 L (2,720 cc) and the V8 version displacing 3.6 L (3,630 cc). The V6 and the V8 were launched in 2004 and 2006 respectively. The V6 engine meets the Euro IV emissions standards. A DT20 3.0 L (2,993 cc) was added in 2009 and is based on the DT17 2.7
The cam can be seen as a device that converts rotational motion to reciprocating (or sometimes oscillating) motion. [clarification needed] [3] A common example is the camshaft of an automobile, which takes the rotary motion of the engine and converts it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.
