Common Mistakes
- Using it to describe any old engine (must be single-cylinder).
- Assuming it is a modern technical term.
- Confusing it with 'two-stroke' engine (a different classification).

Frequently Asked Questions
Yes, but this is a much rarer, colloquial usage meaning a person with only one lung. The primary meaning is mechanical.
No. 'One-lunger' refers to the number of cylinders (one). 'Two-stroke' refers to the engine's operating cycle. A one-lunger could be either a two-stroke or a four-stroke engine.
Not in modern automotive repair. It is used almost exclusively by historians and enthusiasts of antique vehicles and machinery.
They are synonyms in motorcycle enthusiast circles, but 'one-lunger' has a more antiquated and descriptive flavour, while 'single' is the standard modern shorthand.
