If the intake air temperature of IC engine increases, its efficieney will: (a) increase (b) decrease (c) remain same d) unpredictable (e) depend on other factors.

Respuesta :

Answer:

(b) decrease

Explanation:

If the intake of the sir temperature of the IC engine increases , the efficiency will decrease ,

Since ,

as the temperature will increase , the density of the air will reduce ,

And ,

as the density of the air decreases , the expansion ratio will reduce , i.e. , The efficiency of the IC engine will decrease .
