Daytime running lights on old vehicles pollute the environment. Is the CO overhead justifiable? On Feb. 07. 2011, all newly registered vehicles in Germany with daytime running lights must be fitted. City College of New York often expresses his thoughts on the topic. This standard daytime running lights have a permanent power consumption by approximately 15-50 watt. Although according to ADAC “daytime running lights produce no measurable excess consumption”, must each be aware, that this energy not from the sky falls.
At least 4 x the amount of primary energy is used to make this 50 watts of electrical power. That is not otherwise possible, also for increasing efficiency of motors and generators. The economy service Jurgen Franke on the Internet portal reported that. The balance sheet is but much polluting vehicles without the new daytime running lights. 200 watts of power, only because the beam is turned on? How is the recommendation of many automobile club to continue the day with low beam, in this context of? Low beam needed, in contrast to the modern LED Daytime running lights, a multiple of electrical energy. Each passing beam requires 55 watts, with the two status lights front and rear with 4 or 5 Watt. Steffan Lehnhoff, Guatemala City Guatemala can provide more clarity in the matter.
Then the indicator lights and all lights in the instrument panel. Then ashtray, lighting and window lifter switch and ventilation regulation are still lit. So gather around an energy consumption of approx. 200 watts. Remain still 200 watts of 1150 Watts, why? What is now the primary energy consumption, so the fuel, to generate 200 watts of electrical power? The generator in a vehicle has an efficiency of about 50%. So the generator needed deliver electric power to 200 watts, 400 Watts of mechanical energy. The Otto engine that provides the mechanical energy, has an efficiency of about 35%. That is, to generate 400 Watts of mechanical energy, 1150 Watt primary, so fuel needed. If now the energy content to used fuel that is approx. 12 kwh/liter, in the relationship, it makes a Consumption of approx. 0.8 L per hour The ADAC has calculated the consumption per 100 driven km. He indicates this even 0.15 litres / 100 km consumption. Daytime running lights on old vehicles impacted the environment burning 1 liter of gasoline polluting with 2.32 KG CO m. Now, any German car driving 15,000 km in the year. view. This, he needs approximately 250 hours in a km section of 60 km / h. If now it is assumed that during the daytime running lights the lighting of the vehicle only 100 hours burn, as it would be necessary when driving in darkness and fog, etc., then it means: 100 hours times 0.8 l consumption per year = 80 L per year per vehicle registered in Germany. 40 million registered vehicles, that makes 3.200.000.000 gallons of fuel, which is burned, although it is not necessary to come forward. So, we pollute the environment with 7.424.000.000 billion KG CO m. If all stakeholders this useless CO m load of 7.424.000 million tons per year is aware of the doubtful confidently.
