The high price of gas has led people to find ways to conserve. One solution is to use vehicles that don't run on oil fuel. Electric cars and solar-powered vehicles are viable and utilize sustainable sources of energy, but they are still quite expensive. The cheaper way to conserve fuel is to use an oxygen-sensor extender.
The purpose of oxygen sensors and catalytic converters is to reduce exhaust emissions by monitoring the air/fuel ratio, which may be either rich or lean. A rich mixture means there is too much fuel, while lean ratio indicates a high level of oxygen. The perfect air/fuel ratio is 14.7 parts of gasoline per 1 part of air. If the engine-management computer (EMC) receives a feedback of lean, it will add more fuel. If the ratio is rich, the EMC will subtract some of the fuel it supplies to the engine. Failure of the sensors to maintain the right air/fuel ratio will lead to emissions of hydrocarbons, carbon monoxide and oxides of nitrogen. The reasons sensors might fail are the natural aging of parts, use of fuel contaminated with silicate, use of leaded fuel, or modifying the oxygen sensor or its signal to the EMC.
The oxygen-sensor or O2 extender is an adapter that adjusts the front oxygen sensor so it detects less exhaust flow and will lean the air/fuel ratio. In other words, it tricks the EMC into detecting a normal air/fuel ratio even if it has a lean mixture, thereby consuming less fuel. The oxygen-sensor extender usually works in tandem with the hydrogen generator. The hydrogen generator is another fuel-saving device, but without the oxygen-sensor extender, it will cause the car to use more fuel instead of conserving it.
In modern combustion engines, there are three types of emission to be concerned about. These are hydrocarbons, carbon monoxide and oxides of nitrogen. Hydrocarbons are released when fuel is not burned completely, such as when it's running rich. Carbon monoxide is the result of running slightly rich, and oxides of nitrogen are released when the mixture is lean. Though it prevents pollutants that add to the creation of smog and acid rain, modifying the oxygen sensor or using an oxygen-sensor extender can damage a car's catalytic converter and result in an expensive repair. Today, engineers have already designed automobiles to be as fuel-efficient and eco-friendly as possible so there is no need for modification.
