This 2.8-liter engine is unique in that the V-angle between cylinder banks is 15° rather than the 60° or 90° found in most conventional V-6 engine designs. The engine features a cast-iron crankcase, one light alloy crossflow cylinder head with two valves per cylinder operated by chain-driven overhead camshafts. ('''are you sure? looks like counterflow...''' anyway, installing the turbo will take some work) ( Yes it is crossflow...air goes in by the front and comes out by the back... dont be fooled by the intake that starts out back and goes over the head...) All fuel and ignition requirements of the VR-6 engine are controlled by the Bosch Motronic M2.9 Engine Management System. This Engine Management System features an air mass sensor, dual knock sensors for cylinder-selective ignition knock regulation, and Lambda regulation. Exhaust gases are channeled through a 3-way catalytic converter. Engine Specifications Engine code: AAA Design: Four-stroke, internal combustion engine in "Vee"/in-line Displacement: 2.8 liter Bore diameter: 81.0 mm Stroke: 90.0 mm "Vee" angle: 15° Compression ratio: 10:1 Fuel and ignition systems: Bosch Motronic M2.9 Emission control: Lambda control with catalytic converter The name, VR-6 come from a combination of Vee and the German word Reihenmotor. The combination of the two can be roughly translated as "in-line Vee." Volkswagen has designed the 15° VR-6 to take advantage of conventional in-line six-cylinder engine features (single cylinder head, narrow width and excellent balancing) with the advantages of a V-6 engine design (short overall length and compactness). VR-6 The VR-6 was specifically designed for transverse installation in front-wheel-drive vehicles. By using the narrow 15° VR-6 engine, it was possible to install a six-cylinder engine in existing Volkswagen models. V-6 Conventional Design A wider V-6 engine of conventional design would have required lengthening existing vehicles to provide enough crumple zone between the front of the vehicle and the engine, and between the engine and the passenger cell. Using the narrow VR-6 engine will help Volkswagen meet current and future front-end crash standards. ---- Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
