Todays vechicles are a 1000% more efficent than in 1973 when we traded fuel economy and power for lower emissions. With direct ignition systems emissions are now at near 0 percent Hot & Cold . So if your question is why do todays cars and trucks put out more emissions than when they were built, the answer is poor driving habits, poor maintence, low grades of gas and modifying engines or swapping in less efficent engines in place of more expensive quality built engines . Todays cars and trucks foreign or domestic have the highest standards for fuel,emissions and fuel economy with more power than ever before. We have tried Rotory, turbines, diesel ,and now Hybrid,s of all types, the internal engine has just about reached it,s full potenial and limits, but it is still the greatest design ever developed, and so far nothing has replaced it as cheaply as it can be built today or operate under all the same extreme conditions it does without expensive charging stations, special types of fuel, narrow or limited operating ranges and distances or special places to maintain and repair them. And what about recycling emissions? now that will increase because of all the composites we are forced to use to gain all these new emission, safety and mileage standards, that was pulled out of the air and now forced on us to change for our better? Yes some emissions will increase if we don,t use some common sense of what can or should be done to improve our world without setting impossible goals and killing our automotive industry that has made us the greatest free nation and mobile society in the world.

A modern vehicle has many sensors and modules. There are oxygen (o2) sensor simulators, but such equipment are not for street vehicles due to emissions regulations. Emissions regulations vary by jurisdiction and must be verified first before using them in pollution controlled vehicles.
I think its a very nice question, and you should be proud of it. I'm sure the quality of your questions will continue to increase as you gain more experience in the art.
I think population is directly linked with the envirnoment,with the increase in population there will be more and more use of the gagets which are causing the pollution. The more the population the more will be the use of vehicles and more smoke will be released.And there will be increase in air pollution
The numbers of motor vehicles has doubled since 1990 because the population has been increased since 1990
Do you mean smoke? or do you mean the emissions in general? In general vehicles can produce: Carbon dioxide, carbon monoxide, other hydro carbons, Nitrogen oxides, Particulate matter, unburnt fuel and smoke but the majority is nitrogen and water vapor. I'm not sure what's in the smoke but i think it's just soot, bits of carbon.
i think they all do
China, U.S. and i think Japan
Hi, Snoring is normal today, but yes continue snoring is not good for health. To stop or avoid it you need to follow some home remedies or anti snoring spray. I don't think that snoring can increase the height. So don't worry about it. Regards
i think its 4000
i think .35 or it will be under hood on sticker emissions
you can not adjust emissions there may be a fault if your exhaust is leaking or your oxygen sensor (lambda sensor) is faulty maybe a injector leaking fuel into the cylinder may even be a coil pack or as simple as spark plugs i wouldn't know with out knowing which emissions it is high on i could give you a almost definite answer and explain why i think that if you reply with which emissions it is failing and the numbers
You have to earn the award Best Vehicles i think, or just do really well with vehicles.
