This is a thread for technical information and terms automotive related. And more specifically, technical info and terms for Volkswagen vehicles.
Engine and drivetrain terms
8v- The term commonly used to describe an engine with a valvetrain containing 8 valves. In most cases, this will be a 4 cylinder, ie: 2 valves per cylinder. 1 inlet, 1 exhaust.
16v- The term commonly used to describe an engine with a valvetrain containing 16 valves. In most cases, this will be a 4 cylinder, ie: 4 valves per cylinder. 2 inlet, 2 exhaust.
DOHC- Double Over Head Cam. This is the term used to describe an engine with 2 camshafts in the head, operated directly over the valves. One camshaft operates the inlet valve train, the other operates the exhaust valves. DOHC setups are mainly used in multi valve engines. In the case of the VR6 engine, due to the staggered bores, the two camshafts actually operate the inlet AND exhaust valves for the front or rear cylinders.
Multi Valve- This term describes an engine that has more than 1 inlet and/or exhaust valve per cylinder. Eg, a 16v, 4 cylinder engine.
VR6- Vee Reihe Sechs. Which, when translated to English, means Vee Straight Six.
Common Abbreviations
VAG- Commonly referred to as "Volkswagen Audi Group" or "Volkswagen Automotive Group". The correct term is actually "Volkswagen aktiensgesellschaft", which means "Volkswagen Company Incorporated".
This will do for the moment, i have just written this in to kick this thread off, and I will add more later on.
If you have more useful terms to add, please PM either me, or a moderator and the information will be added. Please do not them in this thread as i would like it to stay as uncluttered as possible, and keep the information restricted to a minimal number of posts.
