Design and Simulation of 2.5 L Dual Fuel (Diesel-CNG) Engine for Performance Parameters 2013-01-2885
The objective of this project is to design of gas mixer venturi as per IS4477 and simulation of dual fuel (Diesel-CNG) engine for performances parameters to examine the BSFC using GT-suite. In present work; a 59 kW diesel engine of 18.5 compression ratio has been converted to operate on dual fuel (Diesel-CNG) keeping same compression ratio with improved fuel economy.
Natural gas is an excellent fuel. Its combustion and emission characteristics are superior to any other realistic competing fuel. There are advanced technologies like closed loop lambda control system and lean combustion are incorporated in the engine to achieve the performance targets.
In the initial stage; experimental testing is conducted for base diesel engine on engine dynamo for performance parameters. Experimental testing data and design data's of base diesel engine are used as input in GT-Suite to predict the performance of the base diesel engine. Mapping in GT-Suite is calibrated & optimized as per experimental results for getting closest result. Then, Experimental results and simulation results for base diesel engine are compared for performance parameters to validate the base diesel engine model of GT-Power.
In second stage, simulation of Dual fuel (Diesel-CNG) engine is done using GT-Power. Dual fuel simulation results are compared with base diesel engine simulation results, experimental results and targeted values.
