Performance Parameters Reevaluate and Predict the Fuel Consumption of Cummin Engine Running on CNG-Diesel Duel Fuel by GT-Power Software

This study's main purpose that is a Cummins diesel engine simulation model using GT-power software assess the ability to convert the diesel engine to the dual-fuel engine and the potential use of dual-fuel (CNG-Diesel) to improve engine efficiency, save the cost of fuel and minimize environmental pollution. In the first stage, the simulation was conducted for the basic diesel engine, based on the engine manufacturer's experimental parameters used as the input in GT-Suite to predict the diesel engine performance. The elements are calibrated and optimized on the GT-Suite map to get results closest to the actual base diesel engine. The value has a maximum deviation of ±5% and validates the basic diesel engine model by GT-power. In the second stage, from the basic diesel engine model in GT-Power design DF (CNG-Diesel) engine. In particular, applying the combination of two distinct parallel combustion models (DIPulse and SITurb) allowed the modelling of premixed and diffuse sections of the dual-fuel combustion process. The DF engine simulation results are compared with based diesel engine simulation results. It is possible to reevaluate the performance parameters and predict the fuel consumption of the Cummin engine.
