Presentation Transcript

  1. The Genesis of an Industry • 1860: Lenoir-motorn • 1865: Hugon-motorn • 1870: Bisschop-motorn • Utankompression; Errani-Anders, Hock • Kompression: Million, de Rochas, Schmidt

  2. Lenoirmotorn • Första IC-motorniproduktion • Elektrisktändning-fleravarianter • Cykel • Luftsugs in innan gas (“Soft” combustion) • Tidförmixning • Förbränning (tryck 0.75 bar -> 4 bar ) • Expansion

  3. Lenoirmotorn

  4. Lenoirmotorn • Problem: • Ickefullständig expansion, η=4-5% • 80-90% värmeförluster, 53% till kylvattnet. • Värmeproblem(3hp = 1.3 m3 vatten) • Rengöring, underhåll, högförbrukning • “Första” bilen (1863) – 3h runt Paris. Ävenbåt.

  5. Hugonmotorn • Lenoir utaneltändning. Tidigareförbränning, bättre expansion • Hugonventil med “Barnett’s trapped-flame” • Flamm-tändningframtiden(i 20-25 år) • Mixningutanförcylindern • 20%-lägreförbrukningän Lenoir. “Stratifierad” • Vattenicylindernförattfånertemperaturen.

  6. Hugonmotorn

  7. Bisschopmotorn • Mestframgångsrikaicke-komp.motorn • 3 årefter Otto ochLangen • P≤0.33hp, billigi drift • Kompakt, luftkyld. • Pålitlig (47 dagar)

  8. Icke-kompressionsbensinmotorer • Errani-Anders • Flytandebränsle, blandningicylindern • Elektrisktändning • Lenoir/Hugoncykel • Hock • LiknandeErrani-Anders • Bränsleiflytandeochgasform • “Eldkastare”

  9. Kompressionsmotorer • Million • Kompressionsmotor • Homogenblandning • De Rochas • Schmidt
