Claims (3)

1. Totaktsmotor (100) af længdeskylningstypen, omfattende: en cylinder (110), i hvilken der er dannet et forbrændingskammer (140); et stempel (112), som glider i cylinderen (110); en udstødningsport (116), som er tilvejebragt ved en første ende af cylinderen (110) i en slagretning af stemplet (112); en udstødningsventil (120), der åbner og lukker udstødningsporten (116); en skylleport (122), der er tilvejebragt i en indvendig omkredsoverflade (110b) af en anden ende af cylinderen (110) i slagretningen af stemplet (112) og indsuger en aktiv gas i forbrændingskammeret (140) i overensstemmelse med en glidebevægelse af stemplet (112); en flerhed af brændstofindsprøjtningsventiler (114, 128), som indsprøjter en brændstofgas til den aktive gas, som er blevet trukket ind fra skylleporten (122) til forbrændingskammeret (140), for derved at generere en forblandet gas; og en brændstofindsprøjtningsstyreenhed (152), kendetegnet ved, at brændstofindsprøjtningsstyreenheden (152) varierer indsprøjtningsretninger af brændstofgas, der indsprøjtes fra en del af eller alle brændstofindsprøjtningsventilerne (114, 128); motoren (100) yderligere omfatter en belastningsbestemmelsesenhed (152), der bestemmer, om totaktsmotoren (100) af længdeskylningstypen er i en tilstand med høj belastning eller i en tilstand med lav belastning, og hvor, hvis en tilstand, der detekteres af belastningsbestemmelsesenheden (152), er tilstanden med høj belastning, så drejer brændstofindsprøjtningssty-reenheden (152) indsprøjtningsretningerne af brændstofgassen til første retninger, som er retninger langs en hvirvelstrøm af den aktive gas, der trækkes ind i cylinderen (110); og hvis en belastningstilstand, der detekteres af belastningsbestemmelsesenheden (152), er tilstanden med lav belastning, så drejer brændstofindsprøjtningsstyreenheden (152) indsprøjtningsretningerne af brændstofgassen til anden retninger, som er retninger, der er tættere på en midterakse af cylinderen (110) end de første retninger.
2. Totaktsmotor (100) af længdeskylningstypen ifølge krav 1, yderligere omfattende: en blowby-detekteringsenhed (132), der detekterer en mængde af blowby af brændstofgas fra udstødningsporten (120), hvor, hvis mængden af blowby af brændstofgassen, der detekteres af blow-by-detekteringsenheden (132), ikke er mindre end en tærskelværdi, så drejer brændstofindsprøjtningsstyreenheden (152) indsprøjtningsretningerne af brændstofgassen til retninger, som er tættere på skylleporten (122) i slagretningen af stemplet (112), end hvis mængden af blowby af brændstofgassen er mindre end tærskelværdien.
3. Totaktsmotor (100) af længdeskylningstypen ifølge krav 1 eller 2, hvor, med hensyn til brændstofindsprøjtningsventilerne (114, 128), en strømningspassagejusteringsmekanisme (230) er tilvejebragt et eller andet sted i en strømningspassage fra et indvendigt område (214) af brændstofindsprøjtningsventilen (114, 128) til et indsprøjtningsudløb (212), gennem hvilket brændstofgassen strømmer.
