1.When the piston is at its highest point in the cylinder (TDC), the cylinder volume is at its; B. largest

2.A complete run through all four stages of engine operation-intake, compression, power and exhaust is called an engine cycle

Explanation

The Top Dead Center (TDC) is a point when the piston of an engine is at the most top of its stroke. The TDC can be reached by the piston when on compression stroke and during the exhaust stroke. At TDC, the cylinder volume is at its largest since it will have more space covered.

An engine that has four strokes works through a complete rotation of the crack shaft which covers the intake, compression, power and exhaust stroke to complete a four cycle engine. One operating cycle is attained when the piston successfully makes two complete passes in the cylinder.

their visual appeal is a sure hook into their content. but big books are also produced for pedagogical reasons, and using them in the classroom makes good teaching sense. an abundance of good children's literature in their lives is vitally important for young children as they strive toward independent reading.
