In this research, we use 1DI type constant volume combustion chamber which may make up strati-fied combustion to construct the design back data of lean-burn engine. Some experiments are con. ducted by the passagehole angle in the adapter of main chamber and sub-chamber. The effects on the combustion characteristics according to the ignition timing are investigated. The used fuel is methanol prospective for alternative fuel. Fuel is injected under l0.78MPa using solenoid and accumulator. As the results of the experiment, combustion characteristics reveals that ignition tim-ing, passagehole angle and shape greatly effects on. Lean inflammability limit is extended to 0.45 in equivalence ratio.<br/>

For the practical use of a fuel injection system using solenoid, some mechanical and electrical problems should be explicitly analyzed. In our study, we have investigated these problems experimentally and have improved such that a solenoid driving circuit is liable to establish a fast reponse and a precise control of injection quantity. This proposed fuel injecton system is capable to control equivalence ratio from low level to high level. Therefore, we expect that this proposed system should be applicable to an actual engine.
