Investigation on Combustion Characteristics of Methanol-Syngas Fuel

Abstract Methanol has a broad application prospect in internal combustion engine due to its renewable and environment-friendly characteristics. In this research, a method of using mixture of methanol and syngas as internal combustion engine fuel is proposed, while the syngas is produced by dissociating the methanol through making use of the exhaust heat of the engine. By analyzing reaction path of fuel oxidation and sensitivity analysis of elementary reactions, the effect of syngas on the oxidation process of fuel was studied. The effect of blending ratio and equivalence ratio on ignition delay time and laminar flame speed was investigated. The research results can provide theoretical guidance for the application of methanol-syngas fuel in internal combustion engine.
