Abstract

In this study, a micro gas turbine (MGT) was used for a series of Hybrid electric vehicles (SHEV). at first, the effect of turbine inlet temperature (TIT) and compressor pressure ratio in the T700-GE-401C engine cycle were investigated on performance parameters such as thermal efficiency (𝞰) and output power) and specific fuel consumption (PSFC). to optimize 𝞰 and the supplementary of 400W as P_net, the design variables parameters consist of TIT, compression pressure ratio, and inlet air mass flow rate were calculated. Accordingly, Concept-A was used to use in SHEV with the requirement output converted with an electrical generator based on turboshaft engine T700-GE-401C with additive Compression refrigeration cycle to optimize cycle for development at Concept-B rather than Concept-A a heat recovery was added. effect of 𝞰, P_net, and PSFC for both Concept-A and Concept-B for 𝞰 was orderly 53.84,55,63 and 54.90 303K according to COP 2,4,6 respectively. also, the effects of diesel fuel and liquid natural gas on the cost of fuel Concept-B fuel consumption cost were investigated. the results showed that the use of diesel fuel in diesel Concept- B rather than the other fuels used in this study has the lowest cost.
