Operating, servicing and maintaining a passenger vehicle or off-road vehicle can expose you to chemicals including engine exhaust, carbon, phthalates, and lead, known to the State of California to cause cancer and birth defects or other reproductive harm.
To minimize exposure, avoid breathing exhaust, do not idle the engine except as necessary, service your vehicle in a well-ventilated area and wear gloves and or wash your hands frequently when servicing your vehicle.
Hydrocarbon + O2 = H20 & CO2 idealistic chemical reaction that virtually never occurs in real life
Air only about 20% oxygen, O2, most of it Nitrogen, so when an air breathing engine mixes air with fuel, some of that nitrogen reacts with the fuel and oxygen, producing photochemical smog components that are toxic substances, linked to diseases in medical studies and scientific evidence. Known as trace pollutants, the overwhelming vast majority of engine exhaust made of water vapor are carbon dioxide, similar to human breath.
Gasoline Fueled Engine Pollution Remediated by New Catalytic Converters
Problem for public health and the environment are the trace pollutants, oxides of nitrogen, HC, particulate, carbon monoxide, fumes, vapors, smog forming components, that hit the red hot zirconia stabilized aluminum oxide ceramic honeycomb inner structure of the catalytic converter slurry coated in catalytic noble metals that are breaking down pollutants into CO2 and H20 and non-toxic gases like N2 and O2 emitted, with a new engine and new catalyst, about 97% reduction in smog forming toxic components in exhaust gas, once the ICE vehicle engine and cat are fully hot, after 3 to 9 minutes of operating driving, where the heat soaking of the cat makes it red hot and fully operational are remediating toxic exhaust pollutants into non-toxic gas emissions, while the engine becomes more efficient able to operate at leaner air fuel ratios once the thermostat opens and the coolant flowing into the radiator, forming a heat balance with the aluminum block and head, pistons, wrist pins, con rods, crankshaft, transmission and exhaust system all fully warmed up and working properly.
Emissions Controls Degraded as they AGE
As vehicles age, both in terms of miles and hours of operation, the emissions controls reduce function because of breaking down. The catalytic converts noble metals, Rhodium, Palladium & Platinum, when red hot in hot exhaust gas, slowly evaporate, even metals at high temperature have a vapor pressure.
This means that after 30,000 miles or 3000 hours, that new catalytic converter has lost about half of the noble catalytic metals that blew away slowly as nanogram per mile quantities in the exhaust gas, so everyone breathing near a roadway in USA is microdosing platinum, palladium and rhodium, rare expensive metals, probably also unhealthy to breath as nano fine dust in smog, normally heavy metals are toxic to the human body.
