During the __ stroke, the piston is traveling from BDC to TDC pushing gases out of the cylinder. a. Intake b. Compression c. Power d. Exhaust

## Step 1<br />The problem is about the four-stroke internal combustion engine cycle. The four strokes are intake, compression, power, and exhaust. <br /><br />## Step 2<br />During the intake stroke, the piston moves from the top dead center (TDC) to the bottom dead center (BDC), drawing in a mixture of fuel and air into the cylinder.<br /><br />## Step 3<br />The compression stroke follows, where the piston moves back up from BDC to TDC, compressing the fuel-air mixture.<br /><br />## Step 4<br />The power stroke is next, where the piston moves from TDC to BDC, igniting the compressed fuel-air mixture and pushing gases out of the cylinder.<br /><br />## Step 5<br />Finally, the exhaust stroke occurs, where the piston moves from BDC to TDC, pushing the burnt gases out of the cylinder.<br /><br />## Step 6<br />Given the problem statement, the piston is moving from BDC to TDC, pushing gases out of the cylinder. This corresponds to the power stroke.
