Suppose two engines, one SI, the other CI, have the same temperature range, T 1 = 300K

Question:

Suppose two engines, one SI, the other CI, have the same temperature range, T1 = 300K and T3 = 1800K. Suppose the SI engine, modeled as an ideal Otto cycle, has a compression ratio of 10:1, while the CI engine, modeled as an ideal Diesel cycle, has twice the compression ratio, 20:1. Using cold air standard assumptions, what is the efficiency of each engine? How much more efficient is the diesel engine?
