Item MEAN VALUE ENGINE MODELING FOR HEV PURPOSE A CASE STUDY: HBO ENGINE(2022-01-18) Çakmak, Nevzat; Bayka, A. Demir; Ertan, H. BülentIn this thesis, two cases for conventional vehicle to hybrid electric vehicle conversion were studied. In the first case, series hybrid architecture was assumed; and the internal combustion engine was assumed to be used as a part of range extender or charge module. In the second case, parallel hybrid architecture was assumed; and internal combustion engine was supported with wheel-hub brussless DC motors assembled on the rear wheels of vehicle. And, new design single cylinder spark ignited HBO engine and a BLDC motor prototype were used in the case studies. In both cases, the accurate mathematical models of the sub-systems of HEV are necessary. So, mean value engine modeling approach to model sub-systems of the spark ignited internal combustion engine was studied. And, some sub-systems of the HBO engine were modeled with mean value engine modeling approach and tested. Also, a novel electronic fuel injection system/kit which senses the air flow through the intake port to determine the engine stroke was designed and constructed; then it was used on the engine equipped with carburetor to electronic PFI engine. After the hybrid vehicle architectures, traction motor types and their mathematical models were presented, parallel hybrid architecture was applied with a custom wheel-hub BLDC motor prototype. The motor prototype was designed, manufactured and assembled on the rear wheel assembly of the Fiat, Doblo to convert a conventional vehicle to a hybrid vehicle -for second case-; and the motor-wheel assembly was tested on the dynamometer. HBO represents the first letters of the designer`s name, Hasan Basri Ozdamar
