Morphology
The phrase is fully compositional: a 'direct injection diesel' denotes a diesel (engine/type) that uses 'direct' injection—i.e., fuel injected directly—so a learner who knows 'direct', 'injection' and 'diesel' can infer the meaning. This technical compound follows regular English noun-modifier composition and has clear equivalents in other languages, supporting high transparency for B1 learners.
Etymology
Direct injection diesel is a type of diesel engine where direct injection means the fuel is sent straight into the part of the engine where it burns, like pouring fuel straight on a small fire instead of into a cup first. So, because the fuel goes straight to the burning area, the engine 'uses less fuel' and makes less smoke, which is why the term describes a more efficient diesel engine.
