5. Name the four strokes of an automotive engine. __

## Step 1<br />The four strokes of an automotive engine are the intake stroke, compression stroke, power stroke, and exhaust stroke. <br /><br />## Step 2<br />During the intake stroke, the piston moves down in the cylinder, creating a vacuum that draws in the air-fuel mixture.<br /><br />## Step 3<br />The compression stroke follows, where the piston moves back up, compressing the air-fuel mixture.<br /><br />## Step 4<br />The power stroke is next, where the compressed air-fuel mixture is ignited, causing an explosion that forces the piston back down.<br /><br />## Step 5<br />Finally, the exhaust stroke occurs, where the piston moves back up again, pushing the burned gases out of the cylinder.
