Because - if an engine (powered by fossil fuels) is running - even at idling speed, it's still producing waste gasses - which polute the atmosphere !
Because even idling engines use fuel.
turn up the idling!
I read a report maybe ten - fifteen years ago about an experiment conducted by Mercedes-Benz on heavy-duty truck Diesel engines. They found that switching the engines off and back on again thirty times per minute - i.e., about as fast as it is possible to do - used less fuel than leaving the engines idling for the same minute. This would seem to answer this question! But I cannot find the original source document. Can anyone else help?
Switching off the engine while waiting at a traffic light can significantly reduce fuel consumption and lower greenhouse gas emissions, which contributes to environmental protection. Additionally, it minimizes engine wear and tear, potentially extending the life of the vehicle. Furthermore, idling engines can produce harmful pollutants, so turning off the engine promotes better air quality for everyone. Overall, this simple action supports both economic and environmental benefits.
Cars emit the most pollutants when accelerating. If the lights are synchronized to allow the heaviest flow of traffic to move without stopping and starting the need for acceleration is minimized and pollution reduced. An added benefit is that, since cars also emit more pollution when idling, unless they turn off their engines, allowing more cars to travel in their most efficient engine speed range is enhanced by light sychronization.
Most '86 Caprice engines were fitted with a four barrel carb which requires occasional adjustment to keep idle at reasonable speed.
my idling on my 2001 ford focus is not idling correct, tried to adjust idling but there is no screw or way to adjust why?
Irratic idling condition is indication of intake/inlet manifold gasket leak. Change gasket immediately. This particularly applies to EFI engines. Newaz.
Fast idling of an engine when it is cold typically indicates that the engine's cold start enrichment system is functioning, which allows for a richer fuel-air mixture to aid in starting and warming up the engine. This is common in carbureted engines or can be managed by the engine control unit in modern fuel-injected engines. If the engine continues to idle fast after warming up, it may suggest issues like a malfunctioning idle air control valve or vacuum leaks.
Yes, That is why new cars are coming with a stop-start feature. I the engine will shut off if the car is stationary for a given amount of time( to improve mpg).
Car engines are demanding and require proper care to be taken. Failure to do so can result in problems with fuel, ignition, emissions, and other various systems. A vehicle is said to be idling when it has sufficient power to work the steering or other components but not enough to move the vehicle itself.
I sat in my car in the driveway with the car idling, waiting for the kids to come out.
