Ford Triton engine
Encyclopedia : F : FO : FOR : Ford Triton engine
The Triton engine is Ford's modern line of overhead camshaft (OHC) V8 and V10 Modular truck engines.
4.6 Triton
The smallest Triton was the 4.6 L (4605 cc/281 in³) V8, based on the 90° Ford Modular engine design. Bore of the iron block is 3.55 in and stroke is 3.54 in. This engine is available with either a cast iron or aluminum block, but both use aluminum heads. All 4.6 L Tritons are either 2-valve SOHC or, with the introduction of the 2006 Ford Explorer, 3-valve SOHC designs.
Ford's plant in Romeo, Michigan produces five different 4.6 L modular V8s, of which two are Tritons. The two Triton lines are the cast iron units used in the Ford F-Series, Expedition, and Econoline and the aluminum block versions used in the Ford Explorer and Mercury Mountaineer.
The 2-valve SOHC version in the 2001 and later model years produces 231 hp (173 kW) at 4750 rpm and 293 ft·lbf (397 Nm) of torque at 3450 rpm. The 3-valve SOHC version produces 292 hp (218 kW) at 5750 rpm and 300 ft·lbf (407 Nm) of torque at 3250 rpm. Both use multi-port fuel injection, roller rockers, fracture-split forged powder metal connecting rods, and an assembled reinforced plastic intake manifold.
Applications:
- Aluminum block
- * 2002-present Ford Explorer
- * 2002-present Mercury Mountaineer
- Cast iron block
- * 1997-present Ford F-150/F-250
- * 1998-2004 Ford Expedition
- * 1997-present Ford E-Series
5.4 Triton
Another Triton based on the Ford Modular engine design was the 5.4 L (330 in³) iron/aluminum V8. Bore is the same as the 4.6, but stroke is lengthened to 4.17 in. The 5.4 L Triton family is available in two different versions:
2-valve
The basic 5.4 L Triton is built in Windsor, Ontario at the Essex Engine plant. As of 2004, it was used in most Ford trucks. It has a cast iron engine block and aluminum SOHC 2-valve cylinder heads. It uses multi-port fuel injection, roller rockers, fracture-split powder metal connecting rods, forged steel crankshaft and an assembled reinforced plastic intake manifold.
Output for the 1999 and later model years was 260 hp (194 kW) at 4500 rpm with 350 ft·lbf (474 Nm) of torque at 2300 rpm.
Applications:
- 1998 Lincoln Navigator
- 1997.5-2004 Ford F-Series (2004 availability in F-150 Heritage Edition only)
- 2000-2005 Ford Excursion
- 1998-2004 Ford Expedition
- 1999-2004 Ford F-Series (Super Duty)
- 1997.5-2006 Ford E-Series
3-valve
In 2004, Ford introduced a new 3-valve SOHC head, improving horsepower and torque over the older 2-valve SOHC version. This engine also includes Variable Cam Timing, and first appeared in Australian Ford models [link]. The engine is built in Windsor, Ontario at Ford's Essex Engine plant.
It has a cast iron engine block and aluminum cylinder heads. It uses multi-port fuel injection, has roller finger followers, fracture-split forged powder metal connecting rods, forged steel crankshaft and the intake manifold is assembled of reinforced plastic.
Output is 300 hp (224 kW) at 5000 RPM with 365 ft·lbf (495 Nm) of torque at 3750 RPM.
Applications:
- 2004-present Ford F-Series
- 2005-present Ford F-Series (Super Duty)
- 2005-present Ford Expedition
- 2005-present Lincoln Navigator
- 2006-present Lincoln Mark LT
6.8 Triton V10
Ford built a V10 variant for use in large trucks. It displaces 6.8 L (6802 cc/415 in³) and bore and stroke are 90.2 mm and 105.7 mm, the same as the 5.4 L V8. Both 2-valve and 3-valve versions are produced.
2-valve
The 2-valve version, built at Ford's Windsor, Ontario LVL engine line, was the first. Introduced in 1997, it has an cast iron engine block and aluminum SOHC 2-valve cylinder heads. It uses multi-port fuel injection, roller followers, fracture-split forged powder metal connecting rods, forged steel crankshaft and a cast aluminum intake manifold.
Output for the 2001 and later model years is 310 hp (231 kW) at 4250 rpm with 425 ft·lbf (576 Nm) of torque at 3250 rpm.
Applications:
- 2000-2005 Ford Excursion
- 1999-2004 Ford F-Series (Super Duty)
- 1997-2006 Ford E-Series
3-valve
For 2005, Ford introduced a 3-valve version of the 6.8 L V10. This is built alongside the 2 valve engine at Ford's Windsor, Ontario engine plant.
Output is 362 hp (266 kW) and 457 ft·lbf (620 N·m).
Applications:
- 2005-2006 Ford F-Series (Super Duty)
InTech
Lincoln introduced the 4-valve DOHC InTech version of the 5.4 L modular engine in 1999 and the 4.6L version in 2003. They both feature DOHC heads with 4 valves per cylinder. The Navigator 4-valve DOHC cylinder heads are unique to its application while the Aviator 4-valve DOHC cylinder heads are identical to those found on 2003-2004 Ford Mustang Cobras, 2003 - 2004 Ford Mustang Mach 1s, and 2003 - 2004 Mercury Marauders.
The 5.4 L engine uses a cast iron engine block and aluminum cylinder heads while the 4.6 L has all aluminum construction. They are built at the Romeo, Michigan assembly plant. The InTech V8s use multi-port fuel injection, roller finger followers, and feature fracture-split powder metal connecting rods. The Navigator 5.4 L used a forged steel crankshaft while the Aviator 4.6 L used a lighter cast iron crankshaft. The 5.4 L used a reinforced plastic intake manifold while the Aviator 4.6 L used an aluminum intake manifold with variable runner lengths. The Aviator intake manifold is similar in design to the Ford Mustang FR500 intake manifold sold through Ford Racing Performance Parts (FRPP) though construction material, runner lengths, and throttle bodies differ.
Applications:
- 1999-2004 Lincoln Navigator 5.4 L, 300 hp (224 kW) and 355 ft·lbf (481 N·m)
- 2002 Lincoln Blackwood 5.4 L, 300 hp (224 kW) and 355 ft·lbf (481 N·m)
- 2003-2005 Lincoln Aviator 4.6 L, 302 hp (225 kW) and 318 ft·lbf (431 N·m)
