Ideal Otto efficiency depends on compression ratio and the heat capacity ratio, 1.4 for air. A ratio of 10 gives about 60 percent ideally; real petrol engines reach roughly 30 to 40. Pixel-art kiss-cut sticker in 2, 3, 4 and 6 inches; equation, symbols and sources in the physics panel below.\u003c\/p\u003e","brand":"Printify","offers":[{"title":"2\" × 2\" \/ White","offer_id":50658902835303,"sku":"31853483841781669337","price":4.99,"currency_code":"USD","in_stock":true},{"title":"3\" × 3\" \/ White","offer_id":50658902868071,"sku":"43705821430589526947","price":6.99,"currency_code":"USD","in_stock":true},{"title":"4\" × 4\" \/ White","offer_id":50658902900839,"sku":"33110101231505565178","price":8.99,"currency_code":"USD","in_stock":true},{"title":"6\" × 6\" \/ White","offer_id":50658902933607,"sku":"30224424684338691507","price":11.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/8746\/9159\/files\/01_clean_b52bc974-50d9-4c65-820a-53ad0ccf8c8b.jpg?v=1792807116","url":"https:\/\/pixelatedphysics.com\/products\/ottix-otto-cycle-efficiency-pixel-sticker","provider":"Pixelated Physics","version":"1.0","type":"link"}
