Variable Valve Control - VVC
Introduction
The 1.8 litre 16 valve ‘K’ Series engine with Variable Valve control, (VVC), is available in
the MG-F and the New Rover 200 series.
The 1.8 litre VVC engine also employs the MEMs 2J Engine Management System
The engine shares the key design features of the four cylinder ‘K’ Series engine, with the
ultra light, 'sandwich' construction of low pressure aluminium sand castings, held together
by high tensile through bolts for strength and low distortion.
The VVC engine also includes lightweight hydraulic tappets and lightweight pistons, giving
smoother running, particularly at higher engine speeds. The engine also includes 'damp
cylinder liners', first introduced to ‘K’ Series engines in 1995.
The main emphasis in this workbook is the overhaul procedure of the VVC cylinder head
with the aid of special tools.
To begin with, the following text will explain the operating principles of the VVC
mechanism.
