What limits the compression ratio in the Otto cycle? Autoignition – Limit for Compression Ratio The unburned mixture may autoignite by detonating from pressure and heat alone, rather than ignite from the spark plug at exactly the right time. The engine knocking can be reduced by using high-octane fuel, which increases the gasoline’s resistance to […]
How is the scientific method related to the engineering design process?
How is the scientific method related to the engineering design process? Scientists use the scientific method to make testable explanations and predictions about the world. A scientist asks a question and develops an experiment, or set of experiments, to answer that question. Engineers use the engineering design process to create solutions to problems. How is […]

Why are planetary gears used in automatic transmissions?
Why are planetary gears used in automatic transmissions? An automatic transmission usually has more than one planetary gear set. They work together to create multiple gear ratios. Because the gears are in constant mesh in a planetary gear system, gear changes are made without engaging or disengaging gears, like you do on a manual transmission. […]
