111. in order to prevent formation of carbon on the injector, the temperature of nozzle tip should be (a) less than 100°c (b) between 100-250°c (c) between 250 - 300°c (d) between 400 - 500°c (e) between 500 - 1000°c.

(c) 250-300°C

Explanation:

In order to prevent the formation of carbon on the injector the temperature on the nozzle tip should be in between the 250°C to 300°C .The minimum temperature required to prevent the formation of carbon on the injector should be 250°C but it should not be greater than 300°C

so option (c) will be the correct answer

e) none of the above answers are correct
