Which outcome occurs in a diesel engine when fuel injection timing is excessively advanced?

💡 Explanation

When fuel injection is advanced, the combustion occurs prematurely because there's less time for mixing, leading to higher peak pressures and potential detonation (knock). Therefore elevated cylinder pressure and knock occur, rather than reduced temperature, increased soot, or improved efficiency resulting from optimized timing.
