Problem 1 (100 pts): You are investigating the performance of a spark-ignition engine to be operated with a new gasoline fuel blend with a substantially higher auto-ignition temperature than traditional fuel, which allows for compression ratios up to 20. In this first-cut analysis, you are required to estimate the efficiency of the SI cycle for compression ratios between 5 and 20 based on the ideal Otto cycle, with one exception: you need to account for frictional loss during the compression...

Problem 3 In modern high-speed compression ignition engines, fuel is injected into the combustion chamber much sooner than in early diesel engines. That means, heat is added partly at constant volume and partly at constant pressure. The advantage of this modification is that more time is available for the fuel to completely combust. The ideal dual cycle consists of the following operations: • Process -: Isentropic compression • Process -3: Addition of heat at constant volume. • Process - Addition...
