Investigation on the process of injection of commercial grade and blended fuel in a diesel engine

Purpose. A computational valuation of the parameters process commercial grade and blended fuel flow in injector nozzle a locomotive diesel engine, its impact on spraying conditions combustion chamber. Methodology. The scientific investigation is based using technique comparative numerical experiment. Modern methods fluid dynamics are used for simulating processes Findings. It was found that when working with maximum pressure area well 85MPa, velocity injection hole reaches 434 m/s, whereas alcohol decreases to 429 m/s (at 25% concentration). Due lower saturated vapours fuel, as compared fuel-air mixing degrade at operating duty being investigated. Originality. helped study composition changes nozzle, into chamber conditions. results develop recommendations ensuring effective ICE operation fuel. Practical value. change should be taken account choosing advance angles fueling principles order ensure high economic ecological performance.
