AReduce engine speed to idle before removing the filter.
BSoak the dirty filter in kerosene only.
CBlow out the air inlet with compressed air.
DWith the engine stopped, cover the air inlet after removing the filter.
AI Explanation
The correct answer is D) With the engine stopped, cover the air inlet after removing the filter. When cleaning the air filter on a diesel engine equipped with a turbocharger, it is important to take this precaution to prevent any debris or foreign objects from being drawn into the turbocharger. With the engine stopped, covering the air inlet after removing the filter ensures that no unwanted material can enter the turbocharger, which could potentially cause damage to the delicate components. The other options, such as reducing engine speed or using compressed air, do not adequately address the risk of foreign object ingestion by the turbocharger.
