Fuel is burned outside the engine. Fuel is burned inside the engine. Fuel is compressed to a point where the temperature is high enough for spontaneous combustion. Write a paragraph explaining why two-cycle engines are made, even though they are inefficient. Physical Science 1.
Ice absorbs heat from the water as it melts.
This property causes pipes to break when the water in them freezes. In an internal-combustion engine, the crankshaft changes linear motion into rotational motion. Because of their offset connection to the crankshaft, as the pistons move up and down, the crankshaft rotates. Once rotational motion is achieved, the only thing left to be done is change the direction of rotation to make an automobile move.
