Dodge Oxygen Sensor

Featured Dodge Oxygen Sensor Models

Gasoline engines run best when the air-fuel mixture is accurate. The air-fuel mixture must be controlled to reduce exhaust pollutant emissions. This is the reason why every modern vehicle including your Dodge vehicle and most cars produced after 1980 are equipped with an oxygen sensor. Oxygen sensor is part of the emissions control system and feeds data to the engine management computer. The catalytic converter, also an important part for emission control, also likes a controlled lean air-fuel mixture. The purpose of your Dodge oxygen sensor is to help the engine run as efficiently as possible and also to produce as few emissions as possible.

How do they perform this task? Oxygen sensors detect the air-fuel mixture of a gasoline engine by measuring the amount of oxygen in the exhaust gas. There is a specific ratio of air and gasoline that is perfect, and that ratio is 14.7:1 (different fuels have different perfect ratios — the ratio depends on the amount of hydrogen and carbon found in a given amount of fuel). If there is less air than this perfect ratio, then there will be fuel left over after combustion. This is called a rich mixture. Rich mixtures are dreadful because the unburned fuel produces pollution.

On the other hand, if there is more air than this perfect ratio, then there is excess in oxygen, and this is called lean mixture. A lean mixture tends to produce more nitrogen-oxide pollutants, and, in some cases, it causes poor performance and even engine damage. The fuel-injection system will trim the mixture richer or leaner based on the signal from the oxygen sensor. The engine's computer looks at the voltage to determine if the mixture is rich and lean, and adjusts the amount of fuel entering the engine accordingly. This assures that the engine will be given not just the best possible fuel economy but the lowest possible exhaust emissions as well. Dodge oxygen sensors requires a high temperature (>350 C) to operate.

Sensors are usually mounted in the exhaust manifold, where the hot exhaust gases will pass by it. When the oxygen sensor fails, the computer can no longer detect the air-fuel ratio, so it will end up guessing which results to poor car performance and the bad thing is your auto will demand more fuel than it needs. If this thing happens, replacing your Dodge oxygen sensors is the single thing you can do. Here at Parts Train, we will offer you replacement Dodge oxygen sensors that work as efficient as your factory-equipped Dodge oxygen sensors. Parts Train is among the auto parts dealer that provides the best solutions to your car parts needs.
