what's /o/'s views on Exhaust gas recirculation?
>>14794648
Emissions control is gay.
Only active when not on throttle. Helps not end the world as we know it. Anyone removing it on a street car is an idiot.
>>14794648

Can improve part throttle economy and reduce nox emissions on petrol engines.
Only reduces emissions on diesel engines.
Its alright I guess, if you care about that kind of thing>>14794663
>>14794708
There's a difference between "the nature" as in the air literally wherever and "the nature" as in a proper waste storage facility.
>>14794743
Let's be honest here - How many engines are ending up at "proper waste storage" facilities?
>>14794743

Carbon and diesel particulate is far safer contained in a sticky/solid/whatever state than it is blowing around in the air or in your lungs
>>14794777

>>14794942
>Carbon and diesel particulate
More like carbon that mostly stays ground level unless it is windy outside.
>>14794689
How do you get the air in there to begin with?
>>14794700
Nitrous oxide has a net cooling effect on the atmosphere though.
By using EGR's you're literally increasing the amount of warming effect
It's difficult to like it. Circulating exhaust gas into nice, clean, cold intake air always struck be as bonderline sacrilige.
If it wasn't for emissions laws and financial penalties, no-one would use it. Plus, NOx control gets in the way of more interesting technologies, and shifts focus from increased specific power/driveability/fuel economy, which is what drivers care about.
In a way, it's a good thing the EU and EPA make us do it, otherwise we'd end up poisoning ourselves.
>>14795086
thats the joke you melon
>>14794708
Not as bad as DPFs.
>catch nasty particulates in exhaust
>filter blocks up, needs 'regeneration'
>this means running the engine and exhaust super hot and spitting all that crap out into the atmosphere anyway, with the bonus of increased engine wear
>>14795867
The best thing about DPF's is that they filter out only the largest particulate matter, leaving only the really small, nasty shit that can penetrate the lining of your alveoli and give you cancer.
>>14795867
Luckily my truck is DPF & EGR deleted. Emissions control is stupid

Simply by not assembling it in a vacuum.
It's bullshit and designed to increase maintenance costs and whatnot.
Detrimental to the cars performance, like the DPF filter.

>>14795833
Actually port injected engines have fairly low NOx emissions compared to DI. However diesels (as being mainly DI and running ridiculous AFR) are surely an issue.
EGR only functions in part throttle situations. The guys crying about EGR are fucking idiots.
>>14797043
Qualified mechanic/engineer here. Egr is a fucking bad idea. Reduces lifespan of the engine, builds up and eventually blocks the intake manifolds ports. Like the other anon said, might as well shit into your own mouth and call it saving the environment.
>>14794648
EGR is a disaster on the 2000-2002 Toyota MR2 Spyder. The shitty precat matrix would come loose and get sucked back into the cylinders by the EGR/VVT system under certain conditions. Ceramic in your crankcase is a goddamn mess, RIP engine.
>>14797057
You mean like how Isuzu 2.8dt pickups are designed to be serviced every 5000km instead of 15000km like every other diesel of the same generation? Or how ridiculously overpriced and fragile nissan replacement parts are? Get the fuck out of here.
i blocked the EGR on my 1.6 liter toyota engine
do it on anything bigger than a shitcan engine and you are hurting the environment and you are a bad person

Did you even read? Ofcourse they do you fucking retard. Do you actually work in the motor industry? How do you justify a turbo costing 1/3 of the vehicle cost (1.5dt nissan micra)?
>>14794648
I remove it from every vehicle I buy which has it.
>>14797113
>>billions of tons of human excrement, rotten food waste, and trash dumped into the ocean and environment every year
really this is the first place they should look to reduce pollution.
don't want to sound like current year man, but we should be well past that now.
>>14797132
So prove what you said - that someone somewhere decided that the Nissan Micra's turbo cost that much just because they like fucking with the end user and nothing else.
>>14794700
Anyone who wants to keep this shitshow of a century on the road is the real delusional asshole.
>>14795065
>just pray the wind never blows
nice plan anon, but some of us like to leave the house.
It keeps combustion temps down but this is /o/ so that's not true here.
>>14797146
Anon are you implying for a second that motor companies actually care about the average joe? Please explain to me why I have to pay for a (repurposed nissan langley) nissan micra turbo R44,500, whilst a N14 celect plus turbo is R11,800.
>>14797146
I don't really get it when fags think that cars are so badly harmful to the environment.
They sure aren't healthy when you live in the city and breathe fumes in all day, but with so many catalytic converters and shit as standard it's nowhere near as bad as people assume.
I don't see trees that grow on the side of the road wither and die, or grass dry and and go discolored. Where is the fucking issue?
Global warming is a meme and the I don't care if I sound edgy, but the entire world should follow in China's footsteps and impose a 1 child-per-family legislation to decrease worldwide consumption and waste levels.
Also stop fucking dumping chemicals and trash into the ocean and into ecosystems and killing innocent animals YOU NORMIES RRRRRREEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE
It's all for profits.
>>14797181
Cars are the easy target, it lets attention be drawn away from industrial pollution and makes everyone think we're 'saving the planet!'
I mean real pollution here, like dumping in waterways, not those idiots that think water vapor from nuclear power plants is toxic sludge death gas.
>>14797077
EGR kills part-throttle responsiveness.
>>14797172
Sure they want to make money but manufacturers pretty much never deliberately design something to fuck over their customers. Doesn't mean they don't fuck up, but if they actually wanted to screw you over they'd do what you said on all turbos not just one or two.
>>14797211
The problem is not just turbos anon, its the massive increase in mundane or otherwise repurposed parts. The motor industry is design-wise ruled by greedy fucking jews only interestedin the bottom line.
I modify and block every egr i can get my hands on, because it increases the lifespan (sometimes significantly) of injectors, valves and piston rings.

Can anyone confirm that a 2002 kia sedona even has EGR?
>>14798220
Google it pussy
>>14794690
It's already affecting the world, I used to live in one of the nicest places on earth and now it's constantly hot and dry and shitty. Every single time a scientist comes out to talk about climate change, it's 'oh shit uh yeah we overestimated how long it'll take to really start fucking us'. Expect 30 years from now to be a shitty place to be.
>>14798241
Did, and have been for nearly 2 years.
No sign of egr, but everyone swears that it has it.
>>14797080
This happened to the QR25 motor (Nissan 2.5 four banger. Bonus points: the screws that held the secondary runners' butterflies would back out and get sucked in.
That motor had a lot of gestation problems the first few years.

They don't want cars that require extra attention/maintenance because that actually can cost them money in warranty claims.

>3mpg worse than non EGR
Burn 100 gallons of gas, but go x-300 miles. Now you need to burn more gas, which creates more exhaust fumes and uses up more natural resources.
But at least we saved the saved the earth guys!!

I'd assume they figured out that an EGR does more help than harm but of course I could just be retarded.
>>14798397
EGR should increase MPG
>>14798456
>freeoracle.com
I would have better success asking an 8ball.
>>14798443
Wat? How?
It's only a negligible amount I would think.
>>14798443
Maybe it's just diesels that it affects negatively.
From Wikipedia: Though engine manufacturers have refused to release details of the effect of EGR on fuel economy, the EPA regulations of 2002 that led to the introduction of cooled EGR were associated with a 3% drop in engine efficiency, bucking a trend of a .5% a year increase.
>>14798475
>>14798482
It should (theoretically) allow higher AFRs and reduce pumping losses.
Whether it does that in practice is debateable.
>>14797360
Just stick to old cars, that's what I'm doing.
Unless of course you're in california, in which case you'd be stupid not to leave.
>>14798494
I don't think that works for diesels. The AFR is extremely lean (it's one cause of the high NOx emissions, the other being the stratified charge), and pumping losses are low.
Gasoline is a different matter - pumping losses are very high at part load (ie during real world driving), due to the pressure drop over the throttle plate. EGR allows you to open the throttle wider while maintaining stochiometic AFR, thus reducing pumping losses.
>>14797076
Agreed. NOx isn't so much of an issue in gasoline engines due to the homogeneous charge, and also it's easy to convert using a three-way catalyst.
NOx in diesels is a complete pain. The extremely lean AFR near the cylinder walls and high combustion temperatures and high NOx formation. And the overall lean AFR means you can't use a simple rhodium catalyst, but need more complex systems such as selective catalytic reduction.
Unless someone can make HCCI viable or there is some revolution in catalyst chemistry, it's hard to see a future for diesel in passenger cars.
