An engine only works well when it is hot. When cold, poorly lubricated, it wears off and it pollutes. But warming up while stopped also pollutes. So what?
Your car is sleeping out? What are the risks?
It was true, some years ago, especially on diesel vehicles, the recommendation was to run the engine in neutral to heat the engine before starting to drive in cold weather. The reason was to increase the engine oil temperature for proper lubrication and protect the engine. Times have changed. Today’s innovations enable engine oil warm up faster. In addition, the fuel is more expensive, so avoid wasting it off. Finally, pollution is still very important to a locked vehicle.
Ok, what is the best tip to pollute less?
Solutions to get started without wasting: useless to run the engine at idle to warm it, start driving immediately at a moderate speed and accelerate slowly for the first five kilometres. eiver assists in this start-up phase and will reward you if you accelerate moderately and stay in “low speed – high gear.” Otherwise, overconsumption in town raises up to 45% on the first kilometre, 25% on the second. This is also the case for particulate emissions, as catalytic converters do not work optimally when cold.
This really is the best way to optimize first the ramp-up of the engine, then fuel consumption and finally pollution.
