You just described smog control in the 1980s. Funny thing about all those Exhaust Gas Recirculation Valves and Evaporative Emission control systems and positive crankcase ventilation systems - in addition to the fact that NOBODY understood what the hell they did or how they worked, including the lawyers who lobbied for the mandate of their installation - by adding complicated systems to the motors, they made the motors run LESS efficiently, thereby burning more fuel and creating more emissions. It's crazy what happens when the car companies being regulated own the senators who make the laws.

So the hood doesn't have hinges and just lids off like a tupperware lid. Seems a bit too much just to save money but this is a small cheap car. What is happening It's not Renault's video, it's a Czech automotive journalist in the video. He seems to be genuinely excited about it though.

Wow, it got a little misinformed in here. EGR valves can actually work really well at helping fuel economy, emissions (burn all that unburned fuel, dawg), and power. It just has to be done right. Just because nobody did it right and instead just hamfisted the poo poo on their existing engine designs in the 70's doesn't make it a bad thing.

At least on diesels, EGR systems definitely lowers the combustion temperature (to lower NOx emissions), and a lower combustion temperature always means a lower mean effective pressure (all other things being equal), which translates into lower compression, and compression ratio is inversely proportional to BSFC. veedubfreak posted:Is that why cars are actually going up in power and mileage? Well, it's not like EGR systems are making a big difference, but without them some cars would have even better mileage.

Most of those emissions systems reduced NOx/CO/SOx, or were supposed to, but of course increased CO2 and water vapor emissions because... those are what you get when you cleanly burn hydrocarbons. Yes, they made vehicles less efficient until people found better ways to get around it. Not all emissions are created equal, nitrogen and sulfur oxides are smog causing while CO2 and water vapor really don't do much unless you are talking about global warming. Carbon monoxide is just evil poo poo all around.

PCVs are the best. I actually went out of the way to install one on my C10 (1957 engine) to reduce oil fumes coming into the cab.

As an E46 BMW owner, PCVs are the worst. Nothing like living in fear of your oil separator freezing shut/open and blowing up every gasket in your engine/hydrolocking your engine with oil. And no, the cold climate version doesn't magically fix the problem either.

Nothing like living in fear of your oil separator freezing shut/open and blowing up every gasket in your engine/hydrolocking your engine with oil. Why are PCVs so bloody complicated these days? Fixing the PCV on my 855 is like $100, 5 pieces and a few hours. The PCV on the Celica is a single goddamn rubber hose, one end plugs into the valve-cover and the other end hooks up just behind the throttle-plate. It never needs to be hosed with unless the hose rots away from being almost 30 years old. Don't want oil in you're intake? Toss in a small catch-can, empty every oil-change. I'm going to guess emissions are to blame. Terrible Robot fucked around with this message at 00:30 on Mar 21, 2014 |

Some are simply hoses running from crank case to intake, others have check valves etc.

kastein posted:That sounds like BMW owners should be hating oil separators, not PCVs. No the rest of the system is crap; all the hose connections are made of lovely brittle plastic (that I've seen break on installation, never mind five or ten years down the road), and the system is designed in such a way that condensation collects inside (specifically in the oil separator) in very cold weather, freezing and either cracking the separator, or freezing the internal check valve shut (bad) or open (REALLY bad). The "cold weather CCV" version merely consists of insulated hoses; it doesn't actually solve the condensation problem.
