Двигатели Volkswagen Group: технические характеристики и особенности семейства EA211

None

The spark ignition petrol engines listed below operate on the four stroke cycle, and unless stated otherwise, use a wet sump lubrication system, and are water cooled. Since the Volkswagen Group is German, official internal combustion engine performance ratings are published using the International System of Units (commonly abbreviated "SI"), a modern form of the metric system of figures. Motor vehicle engines will have been tested by a Deutsches Institut für Normung (DIN) accredited testing facility, to either the original 80/1269/EEC, or the later 1999/99/EC standards. The standard initial measuring unit for establishing the rated motive power output is the kilowatt (kW); and in their official literature, the power rating may be published in either the kW, or the metric horsepower (often abbreviated "PS" for the German word Pferdestärke), or both, and may also include conversions to imperial units such as the horsepower (hp) or brake horsepower (bhp). (Conversions: one PS = 735.5 watts (W); ˜ 0.98632 hp (SAE)). In case of conflict, the metric power figure of kilowatts (kW) will be stated as the primary figure of reference. For the turning force generated by the engine, the Newton metre (Nm) will be the reference figure of torque. Furthermore, in accordance with European automotive traditions, engines shall be listed in the following ascending order of preference:
Number of cylinders,
Engine displacement (in litres),
Engine configuration, and
Rated motive power output (in kilowatts). The petrol engines which Volkswagen Group previously manufactured and installed are in the list of discontinued Volkswagen Group petrol engines article.

Both vehicle and engine platforms developed by Volkswagen are specified internally as an Entwicklungsauftrag ("EA"), or development assignment. The numbers denoting a particular Entwicklungsauftrag don't follow a strictly chronological scheme, but have generally increased over time.

The EA211 engines are a completely new four cylinder turbocharged and direct injection TSI engines. Compared to its predecessor, the EA211 series is significantly more compact, with installation length shorter, thus offering more interior space. The installation position of the engines has also been optimised. Just as in the diesels, the petrol engines are now mounted with the exhaust side facing backwards and tilted at an angle of 12 degrees. The weight of these petrol engines made of die cast aluminium is only for the 1.2 TSI and for the 1.4 TSI. The crankshaft alone became lighter by 20 per cent; the connecting rods lost 30 per cent of their weight. In addition the connecting rod bearing journals are now hollow drilled and pistons now come with flat bottoms, all of them optimized for lower weight. Regarding thermal management, the EA211 petrol engine is equipped with a modern dual circuit cooling system. That means that a high temperature circuit with a mechanically driven cooling pump cools the basic engine, while a low temperature circuit flows through the intercooler and the turbo charger casing. The cylinder head circuit heats the cabin's interior. The exhaust manifold is integrated into the cylinder head, enabling the engine to warm up more quickly, in turn making heat available quickly for the passenger cabin. At high loads, the exhaust is cooled by the coolant, lowering fuel consumption.

Was winner of the "Best New Engine" category in the 2006 annual competition for International Engine of the Year. Was winner of the "1.0 litre 1.4 litre" category for six consecutive years in the 2006, 2007, 2008, 2009, 2010 and 2011 annual competition for International Engine of the Year. Was winner of the "Green Engine of the Year" category in the 2009 annual competition for International Engine of the Year. Was outright overall winner of the 2009 and 2010 International Engine of the Year annual competition.
