Technician A says there are two basic combustion chamber designs for diesel engines, with numerous variations on each of these designs. Technician B says all diesel
engines can be categorized as having either an IDI combustion chamber or DI
combustion chamber. Who is correct?

An engine runs on the ideal diesel cycle. the cycle has a compression ratio of 20 and a cutoff ratio of 2. the highest temperature in the cycle is 1200 k. if the heat into the system is 300 kj/kg of working fluid and using variable specific heats determine the work produced per mass of working fluid
