QUESTION: 8

Lenoir cycle is used in

Solution:

Lenoir cycle consists of the following processes
• Constant volume heat addition (1-2)
• Reversible adiabatic expansion (2-3)
• Constant pressure heat rejection (3-1)

Lenoir cycle is applicable to pulse jet engines.

QUESTION: 9

With increasing temperature of intake air, IC engine efficiency

Solution:

Due to high inlet temperature, maximum cycle temperature also increases which may cause dissociation.

QUESTION: 10
