Study of the influenceof the «climate control» installation on fuel consumption and emissions of harmful substances by cars at idle with a running enginee

The article is devoted to the issue of improving fuel efficiency and environmental friendliness of cars serving the administrative and management personnel of the oil and gas complex. It is established that the effective ambient temperature, the color of opaque body elements, the power of the internal combustion engine and the passenger compartment volume of the car affects the fuel consumption and the number of specific emissions of harmful substances with exhaust gases when using the «climate control» installation. However, the simplest controllable factor is the color of the opaque body elements, which is characterized by light reflectance. In the course of experimental studies, the dependences of the change in fuel consumption and the share of reducing emissions of harmful substances from exhaust gases of passenger cars with the «climate control» installation on the light reflectance were established. A method has been developed to reduce fuel consumption and the number of specific emissions of harmful substances from exhaust gases of passenger cars with the «climate control» installation, which consists in imparting white color to the vehicle roof and allows reducing fuel consumption by 5.5–10.3 %, and specific emissions of harmful substances by 0.8–2.3 %.
