LR3/Disco 3
The cross-flow cylinder heads are based on a twin valve, central spark plug combustion chamber, with the inlet ports
designed to induce swirl and control the speed of the induction charge. This serves to improve combustion and hence fuel
economy, performance and exhaust emissions.
LH and RH cylinder heads are identical castings.
Camshafts
A single camshaft on each cylinder bank is retained by a camshaft carrier, line bored with the cylinder head. The
camshafts are located by a flange, which also controls end-float.
The LH camshaft incorporates a reluctor, which is used in conjunction with the Camshaft Position (CMP) sensor to
measure engine position.
