Question

Quizplus · Accepted Answer

High engine temperatures can indeed reduce hydrocarbon (HC) and carbon monoxide (CO) emissions because they promote more complete combustion. Incorrect ignition timing can lead to increased production of nitrogen oxides (NOx), as it can cause the engine to run less efficiently and at higher temperatures, which are conditions that favor NOx formation.
