>By idling and revving the engine, harmful pollutants can be released and can lead to problems with the engine down the line.
I'm far from an expert, but this stinks of kike bullshit.
If the catalytic converter is cold, exhaust deposits can form in the cat from unburned fuel when revving up the engine before its warmed up. Cold engines run rich until they get to operating temp.
They're right, to a point. At least if they're talking about revving an engine to warm it faster.
WRT the pollutants, there are two significant factors that can lead to that. One is that the rings haven't expanded and don't seal as well, so fuel and oil can pass them more easily. Oil won't burn well or at all in a gasoline engine so you'll get a lot of gunk out the tailpipe from that. Also, catalytic converters don't really work until they're hot, so you're not getting the reduction of CO, unburned fuel/oil, or NOx.
And like others have said, revving a cold engine causes much more wear because the oil is not as viscous and isn't circulated as well as when the engine is at operating temperature.
So it does sound like they're pushing the kike line, but it does have some big nuggets of truth in it.
Good to know. Honestly this is the first time I hear about revving the engine to defrost the car.
I just scrape off most of the snow and ice and the rest is easily gone in a few minutes of blasting the heater on max.
Yeah that's how pretty much any normal person does it.
Yes it is is kike bullshit. The catalytic converters won't work properly until they hit their operating temperature, but the "harmful pollutants" they release is negligible unless you're running your car in a closed garage. The jews and their shabbos goyim flying all over the world in their private jets to gather at climate change meetings that tell us we're the problem don't give a shit about the environment. It's just about jew control over the goyim.
Thinking about this just now, I'm surprised they haven't tried to tell us climate change is happening because of the 6 gorrillion jews and muh holohoax. I bet if I search that I'll find some article written by a (((journalist))) that says that. Fucking jews.
A cold engine will produce soot the same way holding a spoon in a candle flame causes it to be covered in soot. The cold cylinder wall cools the air-fuel mixture before it fully combusts. That cylinder is kept far too cold by the very cold oil. Until the engine reaches operating temperature the engine is not running as clean or efficient as it can.
But you are right not to trust the jews.
Cars today now have pre-cats for the cold starts. But it's a good idea to not rev your cold engine, let the car do it's warm up start on its own.
This is also good reason to have a large displacement engine, for winter. Below 0, it gets hard for small engines to put out enough heat for the interior.
