Abstract

En förkammarenhet (1) till en cylinder i en förbränningsmotor, omfattande en för-kammare (2) och en till denna ansluten långsträckt munstyckskammare (3) som i sin andra ända har en mängd av munstycksöppningar (4) för anslutning av förkammaren till cylinderns huvudförbränningsutrymme (5). Munstyckskammaren (3) omfattar en åtminstone vid munstycksöppningarna (4) utvidgad del (3b) vars diameter i munstyckskammarens (3) tvärriktning är större än diametern hos delen (3a) mellan munstycksöppningarna och förkammaren.

Claims (4)

1. Förkammarenhet (1) till en cylinder i en förbränningsmotor, omfattande en 5 förkammare (2) och en tili denna ansluten längsträckt munstyckskammare (3) som i sin andra ända har en mängd av munstycksöppningar (4) för att ansluta förkammaren tili cylinderns huvudförbränningsutrymme (5) och som omfattar en ätminstone vid munstycksöppningarna (4) utvidgad del (3b) vars diameter i munstyckskammarens (3) tvärriktning är större än diametern hos 10 delen (3a) imellän munstycksöppningarna och förkammaren, kännetecknad av att utvidgningsdelen (3b) utgör över 50 % av munstyckskammarens (3) totallängd och är utformad som en stympad kon som blir smalare frän munstycksöppningarna (4) i riktning mot förkammaren (2) sä att den stympade konens konvinkel är mindre än 15 grader, heist cirka 10 grader. 15
2. Förkammarenhet enligt patentkrav 1, kännetecknad av att diametern vid den bredaste punkien pä munstyckskammarens (3) nämnda utvidgade del (3b) är cirka 1,25 - 1,65 ganger större än diametern hos delen (3a) imellän nämnda munstycksöppningar och förkammaren.
3. Förkammarenhet enligt patentkrav 1 eller 2, kännetecknad av att muns-20 tyckskammarens utvidgade del (3b) är anordnad att smidigt blir bredare i riktning mot munstycksöppningarna (4).
4. Förkammarenhet enligt nägot av föregäende patentkrav, kännetecknad av att munstycksöppningarnas kanter (4a) är avrundade vid munstyckskamma-ren (3). C\J δ 25 (M i δ X Χ CL h-· 00 m oo o o (M
