Claims (11)
- Krav:1. Længdeskyllet totakts-krydshovedforbrændingsmotor (100), som har flere cylindre, hvor totakts-forbrændingsmotoren (100) er konfigureret til at indsprøjte en brændselsgas ind i mindst én af cylindrene (101) via et brændselsgasforsyningssystem, hvor brændselsgasforsyningssystemet omfatter én eller flere brændselsgasventiler (105) for mindst én cylinder, hvor brændselsgasventilerne (105) er konfigureret til at indsprøjte brændselsgas ind i cylinderen (101) under kompressionsslaget, hvilket muliggør blanding af brændselsgassen med skylleluft og tillader, at blandingen af skylleluft og brændselsgas komprimeres, før den antændes, hvor den ene eller de flere brændselsgasventiler (105) har en brændselsgasdyse (204), som har ét eller flere dyseudløb (206) for at tilvejebringe brændselsgas til det indre af cylinderen, k e n d e t e g n e t ved, at brændselsgasdysen (204) er konfigureret til at introducere en rotationsbevægelse i brændselsgassen.
- 2. Totakts-forbrændingsmotor ifølge krav 1, hvor brændselsgasdysen (204) omfatter et strømændringselement (205), der er konfigureret til at introducere rotationsbevægelsen i brændselsgassen.

- 10. Brændselsgasventil til en totakts-forbrændingsmotor ifølge et hvilket som10 helst af kravene 1 til 9, hvor brændselsgasventilen (105) er indrettet til at indsprøjte brændselsgas ind i cylinderen under kompressionsslaget, hvilket muliggør at brændselsgassen blandes med skylleluft og tillader, at blandingen af skylleluft og brændselsgas komprimeres før den antændes, hvor brændselsstofventilen (105) har en brændselsgasdyse (204), hvor
- 15 brændselsgasdysen (204) har et eller flere dyseudløb ( 206) til at tilvejebringe brændselsgas til det indre af cylinderen, hvor brændselsgasdysen (204) er konfigureret til at indføre en rotationsbevægelse i brændselsgassen.
