Description: A straight-7 is a very unique layout, possibly the largest odd number inline engine to be produced. There are several reasons why these engines are so incredibly rare. Most of those existing are large two-stroke marine power plants and only a single off-road one found its way out of a factory as a production engine: AGCO Power Sisu 9.8-liter. There were no straight seven-cylinder engines ever made for a road car. The main reason is cost as it is difficult to engineer and balance out. Each four-stroke engine fires a cylinder after 720° of a crankshaft revolution which equals a power stroke each 240° for a 3-cylinder or 144° for a 5-cylinder. However, the 7-cylinder is different and 720°/7 equals 102.857142857rep... a repeating decimal. It is also a very long engine besides issues with a torsional vibration of the long crankshaft. Yes, some longer inline-8's existed when the majority died in the 1950's, but a straight-8 is easier to calculate and balance out. I myself wonder what such a gasoline race car engine would sound like... - Vlog - youtube.com/channel/UC-RgHxivhDRREt25nFFXLnQ - Support - patreon.com/visioracer XHV: hvs1HU2yCqNFBJHCvkQk67Beo5XaiXNHb5SVkPTL1whyLhbwTdVmG1z4GProuUqVwpj5KWMU3Y3MMHSLjiYSFVka1Skr29nZPU XMR: 4294E5emhNXVhM1odiiwLFQTq6xcK7y6Z3WYt3fEUan9UqnUTvNX23tGzdgkgksx4n23na1o2rRzS4L6xLQ6RopF6q1MLAd - Disclaimer - This video is fair use under U.S. copyright law because it is transformative in nature, uses no more of the original than necessary and has no negative effect on the market for the original work. - Credits - “SISU Diesel Engine Rotation” by Kelly Last youtube.com/watch?v=7__trbTpZ28 “Starting 25000KW Power 7 Cylinder Marine Diesel Engine 2 Stroke (HEADPHONES)” by marinersgalaxy youtube.com/watch?v=pmFvrR_zcyw “ME MAN B&W 7S 50MC-C” by Ivan Klimchenko youtube.com/watch?v=aR2lNxC6DCM “I7 Inline 7 engine firing order (AGCO POWER/SISU HD 98) AudioVisual demonstration 1 2 4 6 7 5 3” by William Moser youtube.com/watch?v=Ehf0VlE5AKU “Hudson 8 Startup” by nervecenter100 youtube.com/watch?v=tSzb71lhoZA “Kawasaki Triple (?)
