What do you think are the advantages and disadvantages of isothermal constant volume high extension cycle? and how efficient do you think it can be?

Answer Explanation :

ADVANTAGES OF ISOTHERMAL PROCESS

EASE OF MAINTENANCE: there is absence of direct contact between the combustible gas mixture and all moving part in this process LESS NOISE : These engines does not have valves so it is very simple in construction and produce less noiseBETTER PERFORMANCE : these engine have better performance than other enginesLOW TEMPERATURE : these engine can work on low temperature which is also an advantage

DISADVANTAGES OF ISOTHERMAL PROCESS :

GREATER VOLUME AND GREATER WEIGHT: These engine require large volume and large weightSLOWER START: In this process the engine have very slower start which is a disadvantage HIGHER ECONOMIC COST : In this process we need more money this is also an disadvantage

Ireally wish i could but i will do some research and when i find the answer i will come back to assist you ; )
