air you breath thu is espe cially to if you own a ear built during the put sewn years according to the american petroleum institute if your ear u a 1083 or later model it u equipped with a device to control pollutant that would otherwise come from the engine erankeai if you own a ims or ima model it alio has a system for reduc ing tailpipe emissions these device and systems however will continue to work properly and whats more allow the engine to perform satisfactorily only if you have your car checked regu- larly a periodic tuneup will save you money in fuel and re pair costs give you a smoother running ear and help cut down en air pollution iwsi craakcai control the first device to control automotive pollution was in stalled nationally in all 1m3 ears the device called the positive crankease ventila tion or pcv valve was de signed to recirculate unbumed hydrocarbons back to the en gine where they have another chance to burn formerly these unbumed gases called blowby gases escaped past the piston rings into the crankease where they were vented into the air in stallation of the pcv device cut total hydrocarbon emis sions from the typical car by 34 per cent compared with ear without the device the pcv valve will continue to do its job in controlling hy drocarbon emissions if its per iodically inspected and serv iced as required under your ear warranty otherwise you may be in for trouble over a period of time crankease fumes tend to build up gums or varnishes these could cause the valve to stick and not function tuubi poor stsriug if the valve gets stuck in the open position the carburetor will feed the engine too lean a mixture of fuel and air the result- poor starting and pos sible frequent stalling while you wait and idle at a stop light in the more likely event that the valve sticks in the closed position crankease fumes will be trapped in the crankease these fumes will either escape through the oil filler breather cap if the breather cap is clean or form sludge in the crankease this can create corrosive aelds which ruin en gine bearings the best way to prevent for mation of these acids is to have the valve cheeked each time you have your oil changed or engine tuned most car manufacturers rec ommend periodic replacement of the pcv valve this can be done inexpensively and easily by your service station me chanic this preventive main

control systems beginning with ims can these systems ars designed to control both hydrocarbon and fcarbort mo- noalde emissions in met ibm and ims ears the eahauat control system la based on modification of the engine to achieve a lean fuel mixture and retarded ignition to produce higher combustion temperatures cats carbon sbutlsi these exhaust control sys tems together with the pcv valve reduce total hydrocar bon emissions about two- thirds exhaust controls also cut carbon monoxide emis sions by around 60 per cent compared to earlier ears with out such controls these systems are thus very effective in reducing tailpipe emissions but they make reg ular maintenance all the more essential heres why ah vhgime ho waiter what its age with one bad rparh pliie will hoi only perform poorly
