The formation of carbon monoxide in diesel exhaust gases is reduced by_______________.
AI Explanation
The correct answer is C) maintaining proper combustion and scavenging.
Proper combustion and scavenging in a diesel engine help reduce the formation of carbon monoxide in the exhaust gases. Maintaining optimal air-fuel ratios, combustion chamber design, and efficient scavenging of exhaust gases ensures complete combustion, minimizing the production of carbon monoxide as a byproduct.
The other options are incorrect because: A) spraying water into the exhaust pipe would not directly impact the combustion process, B) keeping the exhaust system free of deposits is important but does not address the root cause of carbon monoxide formation, and D) avoiding light load operation may help, but the primary factor is maintaining proper combustion and scavenging.
