Question 83Motor Plants - Assistant Engineer
70% to passTurbulence of the compressed air charge in a diesel engine cylinder increases_______________.
Aignition lag
Bpiston side thrust
Cthe efficiency of fuel combustion
Dcompression pressure
AI Explanation
The correct answer is C) the efficiency of fuel combustion. Turbulence in the compressed air charge of a diesel engine cylinder increases the mixing of the fuel and air, which in turn improves the efficiency of the fuel combustion process. This increased turbulence promotes better air-fuel mixture formation, leading to more complete and efficient burning of the fuel. The other answer choices are incorrect because ignition lag (A) is not affected by turbulence, piston side thrust (B) is a mechanical consideration, and compression pressure (D) is a separate parameter not directly influenced by turbulence in the cylinder.
