Morphology
direct + injection + diesel + engine
The phrase is compositionally built: 'diesel engine' names the type of engine and 'direct injection' describes how fuel is delivered, so a learner who knows the constituent words can infer it refers to a diesel engine where fuel is injected directly. Although somewhat technical, the components combine in a predictable, cross-linguistically familiar way, making the overall meaning transparent to a B1 learner who knows the parts.
Etymology
Direct injection diesel engine gets its name from how fuel is put into the machine: the words direct and injection show the fuel is sprayed straight into the space where it burns. Imagine a small nozzle spraying fuel right into the hot chamber so it burns quickly and with less waste, and that's why these engines use less fuel and make more power.
