Increasing reduction of CO2 emission in hybrid vehicles

Abstract

This article concerns the issue of reduction of CO2 emission in hybrid vehicles. External lighting through LED technology was applied to show additional CO2 savings in these vehicles. The authors propose for hybrid vehicles of M1 category: conditions of testing external lights, research equipment with measuring system and measuring method in order to determine energy savings obtained by application of external LED light. It enables to calculate saving of CO2 emission and estimate potential energy and ecological benefits. Computational formulas of CO2 emission savings and calculated fuel consumption and percentage reduction of CO2 proposed by the authors were used as a confirmation. Average worktime of lighting and three configurations of sources of lighting of hybrid vehicles were used in the analysis: halogen bulb/bulb, xenon/LED lamp and full electroluminescent external lighting.
