The Jaguar AJ-V8 is
a compact V8 piston engine used in many Jaguar vehicles. It was the fourth new engine
type in the history of the company. It is a DOHC design and replaced the Jaguar
AJ6 engine in many cars. It is available in displacements ranging from 3.2 L to
5.0 L, and a supercharged version is also produced. The AJ-V8 was designed to use
Nikasil-coated cylinders rather than the more-common iron cylinder liners. However,
the high-sulphur fuel reacted with the Nikasil liners and caused engine failures.
Jaguar replaced affected engines, and has used conventional cast-iron linings ever
since. The engine uses a two-state Variable Valve Timing system to switch the intake
cam timing by 30°. Newer engines use a more sophisticated system which can vary
intake timing incrementally up to 48°. Other engine features include fracture-split
forged powder metal connecting rods, a special one-piece cast camshaft, and reinforced
plastic intake manifold. The AJ-V8 was on the Ward's 10 Best Engines list for 2000.
- The Jaguar AJ26 4.0 L (3996
cc) engine was introduced in 1996. Vehicles using this engine are
AJ26, 1997-1998 XJ8, 1997-1998 XK8 and AJ27, 1999-2004 XJ8, 1999-2004 XK8 and AJ28,
- The Jaguar AJ26S
the supercharged version of the AJ26 is used in the high-performance R versions
of Jaguar's cars. Vehicles using this engine are the 1998-1999 XJR, 1998-1999
XKR and AJ27S, 2000-2003 XJR, 2000-2003 XKR.
- The Jaguar
3.2 litre variant was the second to be introduced. Vehicles using this
engine are the XJ.
- The Jaguar
3.6 L "3.5" was used in the XJ series as well. Vehicles using
this engine are XJ8.
- The Jaguar
AJ30/AJ35, 3.9L engine variant is a unique displacement used only by Ford
and Lincoln and is built in Ford's Lima, OH engine plant. The AJ35 version introduced
for the 2003 model year added variable valve timing of the intake camshafts and
electronic throttle control. While the block, crankshaft, pistons, and connecting
rods are all unique to this displacement, many other parts are shared with the AJ-V8
engines produced in the UK by Jaguar.
- The Jaguar 4.2 L AJ34
version features a longer 90.3 mm stroke with the same 86 mm bore. Vehicles using
this engine are 2003 XK8, 2003–present S-Type 4.2 and the present XJ8.
- A special 5.0 liter racing engine
was produced with 550 hp though no road car uses this engine.
Jaguar's V12 was one
of the premiere powerplants of the 1970s and 1980s. It was a V12 piston engine,
The engine first seen in the Series 3 E-type of 1971 was based loosely on an earlier
design intended for a Le Mans car, the ill-fated Jaguar XJ13. The V12 was only Jaguar's
second engine design to go into production in the history of the company. The all
alloy block was fitted with removable wet liners and had a SOHC 2-valve alloy head
with flat combustion chambers.
- The original 5.3 L version
had an oversquare 90 mm bore and 70 mm stroke. It produced
210 kW (285 hp) (245 to 299
bhp depending on emission controls and compression ratio) and 400Nm (295 Lb-Ft)
in fuel-injected form. The V12 engine used in the S2 XJ12 and the new XJ-S had a
Lucas fuel injection system which was based around the Bosch D-Jetronic system.
This version was used in the following cars, the Jaguar E-Type, 1975-1981 Jaguar
XJS and the 1972-1981 Jaguar XJ12 (Series 1 and 2).
- A High-Efficiency 5.3 HE
engine. This version of the engine used the special high swirl design 'May' cylinder
head, and had an unusually high compression ratio (10.5:1 - 12.5:1 depending on
market and year). In any given market, power levels remained similar to the previous
model, but fuel economy was up by nearly 50%. The HE V12 engines had a fuel injection
or engine control system from Lucas that was based on the Bosch P-Jetronic system.
The 5.3 HE was used in these cars are the 1981-1992 Jaguar XJ12 (Series 3) and 1981-1992
- The 6.0 HE engine
was stroked to 78.5 mm in 1992 for a displacement of 6.0 L (5994 cc) to make this
the most powerful Jaguar production engine to date. The 6.0 HE was used in the following
cars, 1992-1995 Jaguar XJS, 1993-1995 Jaguar XJ12 (XJ81) and the 1995-1996 Jaguar
