Q7 An engine having a compression ratio of (15:1) operates on the ideal Dual
combustion cycle. At the beginning of compression the air in the cylinder is at
(0.986 bar) and (21 °C). After compression the heat energy supplied at constant
volume increases the temperature to (1100 °C), and the heat energy supplied at
constant pressure takes place over (4%) of the stroke. Calculate the maximum
pressure, the maximum temperature and the cycle efficiency.
