2.4 JTD 20V

TAPPETS

Specifications

Type

Each valve uses a hydraulic tappet operated by a rocker arm, in turn, moved by the camshaft.

The rocker arms are designed to prevent serious damage to the other engine components if the timing belt slips or breaks; in effect, as a result of pre-set fracture lines, the stresses caused through the contact of the valves with the pistons are absorbed.
