sorry for my bad very very bad english
in all benzine engine the exaust flames is blue, benzene vapor create those color, but see yellow/orange flames is caused to "return of flame" (in italiano si dice ritorno di fiamma in inglese non ne ho idea!) this "return of flame" is determined from a not complete combustion of the mixture in the cylinder |
