Question

What happens if atmospheric temperature is too low?

(a) Engine misfires at low loads

(b) Engine consumes more amount of fuel

(c) Engine gets struck up

(d) Exhaust produced comparatively more

This question was posed to me in my homework.

Question is from Lubrication System, Intake and Exhaust Systems in division Diesel Engine Plant of Energy Engineering

Answer 1

The correct choice is (a) Engine misfires at low loads

To elaborate: The air system contains an intake manifold located outside the building with filter to catch dirt which would otherwise cause excessive wear in the engine. If the atmospheric temperature is too low, engine misfires at low loads and hence it is necessary to install a heating element using exhaust gas.
