ENGLISH ABSTRACT: This thesis discusses the development and upgrade of an internal combustion spark-ignition engine test cell. Existing test cell equipment was upgraded and additional sensors were installed onto the engine. Engine refurbishment was also performed. The baseline engine performance was then tested using the original manufacturer equipment engine control unit. An aftermarket ECU was later installed onto the engine to allow for greater control of engine performance parameters. The influence of spark-ignition timing and air-fuel ratio on engine performance and in-cylinder pressure was studied. Engine power and efficiency were greatly affected by these parameters. A single-zone and two-zone heat-release model was implemented to analyse the influence of spark-ignition timing and air-fuel ratio on combustion. The single-zone model provided satisfactory results when compared to the two-zone model. Commercially available software was used to simulate the engine performance and was found to be within 15% of experimental results for high power test conditions. AFRIKAANSE OPSOMMING: In hierdie tesis word die ontwikkeling en opgradering van ‘n interne verbranding vonkontsteking enjin toetssel. Die bestaande toetssel se toerusting was opgradeer en bykoemende sensors was geinstalleer in die enjin. Daar is ook opknappings werk aan die enjin gedoen. Die oorspronklike vervaardige enjin-kontrole eenheid was gebruik om die basislyn van die enjin optrede te bepaal. Op ‘n later stadium is ‘n na-mark-enjinkontrole eenheid (ECU) geinstalleer om sodoende beter kontrole te kan handhaaf op die enjin se prestasie. Die invloed van die vonkontsteking tydsberekening en die brandstof verhouding sowel op enjin prestasie as ook die druk binne-in die silinder was bestudeer. Die enjinkrag en doeltreffendheid was grootliks beinvloed deur hierdie grense. ‘n Enkel sone en dubbel sone hittevrystellings model is geïmplimenteer om die uitwerking van vonkontstekingstyd en lug-brandstof verhouding op verbranding te aniliseer. Die enkel sone hittevrystellings model het bevredigende resultate gelewer in vergelyking met die dubbel sone model. Kommersiële beskikbare sagteware is gebruik om die enjin prestasie te simuleer. Daar is bevind dat dit binne die 15% van eksperimentele resultate vir hoë krag toetstande was. 2019-02-26T20:13:47Z 2019-04-17T08:34:54Z 2019-02-26T20:13:47Z 2019-04-17T08:34:54Z 2019-04 Thesis http://hdl.handle.net/10019.1/106211 en_ZA Stellenbosch University xiv, 125 pages : illustrations application/pdf Stellenbosch : Stellenbosch University |
