Problem 20.21 6 of 12 Constants I Periodic Table In an engine that approximates the Otto cycle (see Figure 20-8 in the textbook), gasoline vapor must be ignited at the end of the cylinder's adiabatic compression by the spark from a spark plug. Part A The ignition temperature of 87-octane gasoline vapor is about 430 °C and, assuming that the working gas is diatomic and enters the cylinder at 30 °C, determine the maximum compression ratio of the engine.
