Ford Oxygen Sensors

Ford oxygen sensors help ecologically conscious drivers cut back on harmful emissions such as carbon monoxide and hydrocarbons, among others. The process of combustion is spectacular to behold, but exhaust (the fourth stroke in a four-stroke engine) is an inevitability. Once the air and fuel mixture inside the chamber has been ignited, its expanding gases need somewhere to go, and that somewhere is, regrettably, the great outdoors.

Fortunately, Ford and other manufacturers have raised their efficiency and pollution standards so that driving takes a less destructive toll on the planet. By building oxygen sensors and catalytic converters into their designs, they achieve two objectives. One, they ensure that the ideal air-to-fuel ratio of 14.7:1 remains fairly constant. Two, they treat harmful emissions inside the car before they're allowed to exit.

Ford Oxygen Sensors vs. Catalytic Converters

Chances are, your Ford car or truck has been built with both pollution-control mechanisms as part of its blueprint. Which is better at reducing emissions? This question is akin to asking which has better efficacy, preventive medicine or treatment. That's because one mechanism aims to perfect the combustion process while the other focuses on the noxious chemicals that are a natural by-product of inefficiency.

While your Ford's oxygen sensor triggers electrical impulses that regulate your engine's air-to-fuel ratio, catalytic converters physically change toxic compounds into more benign ones by altering their chemical structures. There are multiple catalysts that can do the trick, but platinum, palladium, and rhodium are the most common forms.
