Which outcome occurs when high fuel pressure causes incomplete combustion in a diesel engine?

💡 Explanation

Elevated fuel pressure leads to over-rich fuel-air mixtures within cylinders; the mechanism is insufficient residence time for oxidation. This causes incomplete combustion, therefore soot and particulate formation significantly increases, rather than decreasing emissions or lowering cylinder head temperatures associated with leaner burns.
