Inlet / Exhaust Manifolds

Each cylinder is provided with two inlet and two exhaust valves. The valves are operated by cam followers beneath each camshaft. Valve clearances are maintained at zero by a hydraulic tappet system (lash adjuster) pressurised from the main engine lubrication system.

Inlet / Exhaust Manifolds

Two six-branch exhaust manifolds, locate four primary catalytic converters and eight oxygen sensors.

Four engine management oxygen sensors are mounted before the primary catalysts. Four catalyst monitor oxygen sensors are mounted after the primary catalysts.

Intake air is filtered and passed through mass air flow meters (MAF). The air then passes through the throttle bodies into the six branch inlet manifolds.
