Straight-fourteen engine

Straight-fourteen engine is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Straight-fourteen engine rather than just read about it. In short: A straight-14 engine (also known as a inline-14 engine) is a fourteen-cylinder piston engine with all fourteen cylinders mounted in a straight line along the crankcase. This design results in a very long engine, therefore it has only been used as marine propulsion engines in large ships.

Key takeaways

Straight-fourteen engine belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Straight-fourteen engine to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Straight-fourteen engine from memory before moving on to harder problems.

Reference excerpt

A straight-14 engine (also known as a inline-14 engine) is a fourteen-cylinder piston engine with all fourteen cylinders mounted in a straight line along the crankcase. This design results in a very long engine, therefore it has only been used as marine propulsion engines in large ships. The only straight-14 engine known to reach production is part of the Wärtsilä-Sulzer RTA96-C family of 6-cylinder to 14-cylinder two-stroke marine engines. This engine is used in the Emma Mærsk, which was the world's largest container ship when it was built in 2006. The engine produces 80,080 kW (107,390 hp) and displaces 25,340 L (1,546,342 in3), has a bore of 960 mm (38 in) and a stroke of 2,500 mm (98 in). The engine is 27.3 m (90 ft) long, 13.5 m (44 ft) high and weighs 2,300 t (2,535 short tons).

Worked examples

Example 1 — a first encounter with Straight-fourteen engine

Start with the simplest possible case. Write down what Straight-fourteen engine claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 Straight-fourteen engine 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 Straight-fourteen engine 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 Straight-fourteen engine

In research: Straight-fourteen engine appears in physics 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 Straight-fourteen engine 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.
In the classroom: Straight-fourteen engine is common in secondary-school and first-year university syllabi. It links to neighbouring topics 14-cylinder engines, Mechanical engineering stubs, Piston engine configurations, so understanding it makes those chapters shorter.
In everyday life: Look for Straight-fourteen engine outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
