Question 439Motor Plants - Assistant Engineer
70% to passIf the coolant temperature is too low as it passes through internally cooled fuel injectors, the injectors can be damaged by _______________.
Awater condensation in the fuel
Bcorrosion of the nozzle tip
Cdecrease in fuel oil viscosity
Dinadequate lubrication of the needle valve
AI Explanation
The correct answer is B) corrosion of the nozzle tip. Explanation: If the coolant temperature is too low as it passes through internally cooled fuel injectors, the injectors can be damaged by corrosion of the nozzle tip. This is because the low coolant temperature can cause condensation within the injector, leading to the accumulation of water and increased corrosion of the nozzle tip. The other options are incorrect because they do not directly address the issue of low coolant temperature and the resulting damage to the injectors.
