Reference excerpt

List of discontinued Volkswagen Group diesel engines. The compression-ignition diesel engines listed below were formerly used by various marques of automobiles and commercial vehicles of the German automotive concern, Volkswagen Group, and also in Volkswagen Marine and Volkswagen Industrial Motor applications, but are now discontinued. All listed engines 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 European, 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 power output is the kilowatt (kW); and in their official literature, the power rating may be published in either kilowatts, metric horsepower ('Pferdestärke' in German, often abbreviated PS), or both. Power outputs may also include conversions to imperial units such as the horsepower (hp) for the United States and Canadian markets. (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 power output (in kilowatts). The diesel engines which Volkswagen Group currently manufactured and installed in today's vehicles, and Marine and Industrial applications, can be found in the list of Volkswagen Group diesel engines article.

Two-cylinder diesels

0.8 R2 TDI This inline two-cylinder Turbocharged direct injection (TDI) diesel engine is the powerplant of the Volkswagen XL1

Three-cylinder diesels

1.2 R3 PD TDI 3L (EA188) This inline three-cylinder Turbocharged direct injection (TDI) diesel engine is the powerplant of the Volkswagen Lupo 3L and Audi A2 3L, with a low fuel consumption of only 2.99 L/100 km (94.5 mpg‑imp; 78.7 mpg‑US) – hence the "3L" tag. It is based on the 1.4 TDI version, but the cylinder block is made of aluminium alloy, and some of the other components are lighter.

Worked examples

Example 1 — a first encounter with List of discontinued Volkswagen Group diesel engines

Start with the simplest possible case. Write down what List of discontinued Volkswagen Group diesel engines claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of discontinued Volkswagen Group diesel engines before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of discontinued Volkswagen Group diesel engines ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of discontinued Volkswagen Group diesel engines

In research: List of discontinued Volkswagen Group diesel engines appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses List of discontinued Volkswagen Group diesel engines in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
