Thermodynamic analysis of transient cycles using simulation techniques for hydrogen diesel dual-fuel engine

Hydrogen is most abundant energy in the world as the most abundant element with a percentage of approximately 75% of the total mass of the elements of the universe and the cost-benefit compared to diesel gives the advantages to use hydrogen gas fuel as an alternative in running conventional motor fuel. Hydrogen can be produced by an electrolysis process which is a renewable product and hydrogen mixed combustion product including lowest CO, CO2 and hydrocarbons emissions. On the other hand, Dual-fuel hydrogen diesel fuel can increase thermal efficiency and reduce fuel consumption. Increased complexity poses several challenges, including the response of engine with direct injection of diesel dual fuel. For the above reasons are required transient cycles testing. This transient test involves several parameters such as rotational speed that changes spontaneously with at 2000 rpm. Also, the ratio of a number of hydrogen fuel inputs inputted to replace diesel fuel can be done as a parameter to be tested transiently as well. In this study also conducted an analysis of exhaust emissions generated on dual fuel diesel fuel motor. It also performed a 1-D simulation of dual-fuel fuel motor using the AVL Boost to study the response of the hydrogen diesel fuel motor. All hydrogen content, the speed conditions at 1999.5 rpm reach at 97.5 cycles, but in diesel fuel, the same speed is achieved at 105 cycles. The maximum IMEP reaches 7 bars up to 72 percentage H2. After cycle 40, the all hydrogen content will produce an up bit NOx value. In all hydrogen content, the mass fraction CO2 value lower than mass fraction CO

in diesel fuel. Particulates can be reduced by 81.4 % H2 enrichment. This simulation is then used to correct the altered power response experienced by the driver during transient conditions.
