Recall the terms "specific enthalpy" and "enthalpy density" from the module on thermochemistry. how are they different and why must they be considered when choosing a fuel source? 2 engine "knock" is the sound an engine makes when gasoline ignites too soon in the engine cylinder (possibly due to low octane fuel). knocking may cause loss of power, overheating and engine damage knocking may be due to low octane fuel. why? what is meant by octane rating? (research! ) a. how could the composition of gasoline be altered to increase the ease of starting a car in cold weather? (research! ) b.
