Claims (8)
1. Förfarande för start av en förbränningsmotor (1) med åtminstone en cylinder (10) som med en i cylindern (10) förd kolv (12) bildar ett förbränningsrum (11), med en in- sugningskanal (30) för tillförsel av luft eller av en luft-bränsleblandning via åtminstone en insugningsventil (35) in iförbränningsrummet (11), med ett strypspjäll (32) för styr- ning eller reglering av luftströmmen (36) i insugningskanalen (30) och med en bränsle- tillförsel (40) för tillförsel av ett bränsle in i förbränningsrummet (11) eller in i ett insug- ningsrör (34) hos insugningskanalen (30), kännetecknat av att strypspjället (32) stängs under starten av förbränningsmotorn (1) och att bränsletillförseln åtminstone delvis sker under förbränningsmotorns insugningsfas.
2. Förfarande enligt krav 1, kännetecknat av att tillförseln av bränslet sker, så snart gastrycket i insugningsröret (34) eller i förbränningsrummet (11) underskrider ett förut- bestämt tröskelvärde.
3. Förfarande enligt krav 2, kännetecknat av att tröskelvärdet förbestäms i beroende av temperaturen hos förbränningsmotorn (1).
4. Förfarande enligt något av kraven 1-3, kännetecknat av att strypspjället (32) öppnas efter tändning.
5. Förfarande enligt krav 4, kännetecknat av att strypspjället (32) öppnas gradvis i be- roende av van/talet hos förbränningsmotorn (1).
6. Styrenhet (50) för styrning av en förbränningsmotor (1 ) med åtminstone ett, av en cylinder (10) och en kolv (12), bildat förbränningsrum (11), som tillförs luft eller en luft- bränsleblandning via en insugningskanal (30) med ett strypspjäll (32) och ett insug- ningsrör (34), med en bränsletillförsel (40) för tillförsel av bränsle in i förbränningsrum- met (11) eller in i insugningsröret (34), varvid styrenheten (50) innehåller programrutiner för styrning av bränsletillförseln (40) och för inställning av strypspjället (32), känneteck- nad av att i styrenheten (50) är ett program ombesörjt för stängning av strypspjället (32) under en startfas av förbränningsmotorn (1) vid samtidig tillförsel av bränsle under en insugningsfas hos förbränningsmotorn (1). 10 11
7. Styrenhet (50) enligt krav 6, kännetecknad av att styrenheten (50) åtminstone är samordnad en trycksensor (54) för bestämning av gastrycket i insugningsröret (34) och/eller gastrycket i förbränningrummet (11) hos förbränningsmotorn (1) och att styr- enheten (50) åtminstone är samordnad en temperatursensor (52) för bestämning av temperaturen hos förbränningsmotorn (1) och/eller omgivningstemperaturen.
8. Användning av förfarandet eller styrenheten (50) enligt något av de ovanstående kra- ven för start av en förbränningsmotor (1) som drivs med en blandning av bensin och alkohol, särskilt med en blandning av bensin och etanol.
