Abstract

En totaktsmotor av en bestemt konfigurasjon kan få sin avgitte effekt økt ved å kjøre større stempler og ved bruk av porter i stempelskjørtet gjennom hvilke komprimert luft ledes inn i skjørtet gjennom korte passasjer i sylinderhuset som leder luften fra inne i skjørtet til over stempelet. Som et resultat kan det brukes et større stempel for den samme avstand og åpningsstørrelse i blokken, for å spare behovet for omdesign av blokken og veivakselen. En posisjonsjusteringsinnretning for stempelet forflytter det aksialt uten rotasjon av stempelportene ut av innretting med innløpsportene i huset. Stempelstangen holdes i krysshodet ved anvendelse av en flate for å hindre rotasjon, mens en justeringsmutter som dreies frembinger aksial bevegelse i stempelstangen med en låsemutter som sikrer stempelets sluttposisjon.
