Mixture Preparation in a Small Engine Carburator
نویسندگان
چکیده
The objective of this work is related to the problem of mixture preparation in a carburator of a small 1 cylinder 2 stroke engine. A enhanced KIVA3v code has been modified in order to get a geometrically simplified but relatively fast and reliable numerical diagnostics tool. Emphasis was placed on idle speed investigation with an unsteady outflow boundary condition. Mixture formation for closed throttle near the nozzle hole was investigated experimentally with a VideoScope System with the goal to derive proper boundary conditions for the numerical investigation. Kiva3v served as a proper an reliable investigative tool to successfully study all relevant physical phenomena i.e. wall-film, spray breakup as well as providing robust numerical integration for several engine cycles.
