An evolution of the 1964 DOHC prototype “XJ13” engine, the Jaguar V12 engine is a family of SOHC internal combustion V12 engines with a common block design, that were mass-produced by Jaguar Cars for a quarter of a century, from 1971 to 1997, mostly as 5.3‑litres, but later also as 6‑litres, and 7‑litre versions that were deployed in racing.
A hemispherical head ("hemi-head") gives an efficient combustion chamber with minimal heat loss to the head, and allows for two large valves.However, a hemi-head usually allows no more than two valves per cylinder due to the difficulty in arranging the valve gear for four valves at diverging angles, and these large valves are necessarily heavier than those in a multi-valve engine of similar ...
It also features higher flowing cylinder heads sourced from the L92, a more aggressive camshaft with 0.551 in (14 mm) lift, a 10.7:1 compression ratio, a revised valvetrain with 0.236 in (6 mm) offset intake rocker arms, a high-flow intake manifold, and 47 lb (21 kg)/hour fuel injectors from the LS7 engine.
The head is machined flat, with recesses only for inlet and exhaust valves, spark plugs, injectors and so on. The combustion chamber itself is contained within a dished depression in the top of the piston. The Heron head is suitable for petrol and diesel engines, for ohv and ohc valve-gear, and for small and large engine displacement capacities.
The 5.8 is formally known as the Trinity Engine or 5.8-liter V8 engine, which benefits from cylinder heads with improved coolant flow, Ford GT camshafts, piston-cooling oil jets similar to those found on the 5.0 Coyote, new 5-layer MLS head gaskets, an over-rev function that increases the red line to 7000 rpm for up to 8 seconds (from 6250 rpm ...
The hemispherical head design was revived in 1964 for the now-famed 426 Hemi, a big-block, overhead valve 426 cu in (7.0 L) V8. The first engine called "Hemi" by Chrysler, [ b ] the 426 was nicknamed the "elephant engine" at the time, a reference to its high power, heavy weight, and large physical dimensions. [ 17 ]
The 3.0 L (2,967 cc), 220.71 hp (165 kW) V6 used in the Mondeo ST220 is called Duratec ST. 3.0 L (2,967 cc) 204 hp (152 kW) V6 in the Mondeo Titanium is called Duratec SE. 28.1 mpg ‑US (8.4 L/100 km; 33.7 mpg ‑imp) A racing version of this engine exists and is used on mini prototypes like the Juno SS3 V6.
Race Engine of a 1971 Ford Capri RS from Weslake & Co with 320 HP (DIN) at 8.200 rpm with Kugelfischer Injection. Weslake & Co also known as Weslake Research and Development was founded by Harry Weslake, described as England's greatest expert on cylinder head design, [1] [2] with premises in Rye, East Sussex, England.
