Engine Design Evolution

• Describe feature of a flathead engine. (Page 4)The design where the valves

were located in the engine block is called flathead design because the cylinder head simply covered the combustion chamber and included a hole for the spark plug.

• Describe why gasoline and diesel engines are called internal combustion

engines? (Page 4) All gasoline and diesel engines are called internal combustion engines and were design to compress an ignitable mixture.
