d) Comparing the ideal air standard Otto 4 stroke cycle with the ideal air standard 4 stoke Diesel cycle. i) State how does the thermal efficiency compare when running at the same compression ratio. ii) Comparing a modern diesel engine of compression ratio 16 with a modern petrol engine of compression ratio of 8. State and the reason why, which will have the highest thermal efficiency. 5 iii) Briefly describe; when these engines are running at part load how does their thermal efficiency change relative to stochiometric and why. d) Comparing the ideal air standard Otto 4 stroke cycle with the ideal air standard 4 stoke Diesel cycle. i) State how does the thermal efficiency compare when running at the same compression ratio. ii) Comparing a modern diesel engine of compression ratio 16 with a modern petrol engine of compression ratio of 8.
