Exhaust Systems

Oxygen sensors have been integrated on vehicles for more than 30 years. Located in the exhaust system, they monitor fuel-to-air ratio and catalyst efficiency. While working in a hostile...

Catalytic converters are used to clean up car exhaust by burning left over fuel, not burned by the engine. They use particular properties of precious metals to catalyze the burning of hydrocarbons...

The first upstream O2 sensor was introduced on the Volvo 240 in 1976 in the state of California. By 1981, all vehicles were required to be equipped with them. By 1996, with the introduction to OBD...

A vehicle's intake manifold distributes the mixture of fuel and air to the engine cylinders. If the intake manifold is cracked or the mating surfaces are warped, this will cause the fuel/air to...

The oxygen sensor(s) in a vehicle, simply put, are clever devices that monitor the amount of pollution the vehicle dispels from the exhaust system. Although the function of the oxygen sensor goes...

All engines have some source of energy (fuel), whether that energy is electricity, gasoline, hydrogen or some other source. And because all vehicles have engines, all vehicles therefore need an...

A fuel pump is one of the most important parts of a vehicle's fuel and exhaust system. Its job is to pump fuel from the gas tank to the fuel line. If a fuel pump isn't functioning properly, then...

All vehicles come equipped with small engine components called engine oxygen sensors. While there are many different types of oxygen sensors that perform an array of different functions, a faulty...

The exhaust system is set up to take away all the poisonous gases and fumes from your engine--the result of fuel combustion--in order to run the vehicle. Many components comprise the exhaust...

Removal of a catalytic converter is not a task for a novice. It requires the skill of a certified mechanic who is a trained and experienced welder as well as technician. Removing the catalytic...
