Today's technology makes this a little counter intuitive.
So How do your example engineers sell a car with out the easy sell hybrid technology? They don't, The marketing department does that.
Problem identification
Answering "What emissions control device on a car lowers carbon monoxide content?"
Solution design and evalution
Sulphur dioxide, carbon monoxide and fuel emissions.
Carbon Monoxide is the most common gas emitted from a car.
carbon monoxide is a rich indicator, if you are producing too much, you have a fuel system problem.
Catalytic converters.
Carbon monoxide emissions from an oven can be dangerous because this gas is colorless, odorless, and tasteless, making it difficult to detect. Breathing in carbon monoxide can lead to symptoms like headaches, dizziness, nausea, and even death in severe cases. It is important to ensure proper ventilation and maintenance of ovens to prevent the buildup of carbon monoxide.
Carbon monoxide
mostly carbon monoxide, some carbon dioxide, and some water vapor
It produces more carbon monoxide.
Yes it is part of the emissions system. It turns exhaust into lower emissions by burning any unburnt exhaust gases thus reducing unwanted emissions and Carbon Monoxide.
