I6 303-01a-7

DESCRIPTION AND OPERATION

Engine — I6

The 4.0L I6 is a four valve per cylinder, dual overhead

camshaft engine with individual intake and exhaust

variable cam timing units. A distributorless ignition

system with individual coils mounted above the spark

plugs is used. The cylinder block is cast iron, and is

attached to an aluminium oil pan with cross-bolted

main bearing caps to increase rigidity. The oil pump is

mounted on the nose of the crankshaft, and a single

stage roller chain drives the hollow camshafts.

Hydraulic lash adjusters and roller finger followers

activate the valves. An electronic throttle body is

employed together with a variable length intake

manifold. Petrol, LPG and Turbocharged versions are

also available.
