open and the piston istravelling downwards drawing air into the cylinder.The second stroke is thecompression stroke(2).Both valves are closed and the piston is moving up-wards compressing the air in the cylinder.As the piston reaches the top of itsstroke,the compressed air creates such a heat as t","cbCaihO9FHgzm0pH","https://ap.wps.com/l/cbCaihO9FHgzm0pH","pdf",12196228,49,"English","#
