But, aside from the major components of your vehicle's emission system, there are a number of ways to reduce the amount of fuel your vehicle consumes in the first place. By regularly performing tune-ups, maintaining tire pressure, and practicing a few new driving techniques, you will reduce your fuel consumption.
Catalytic converters ("cats" for short) have been a major part of your exhaust since the early 70s and have seen a growth in technology and regulations over the decades. This is especially true in the mid 90s when OBDII (On-Board Diagnostics) evolved. The primary function of your catalytic converter is to convert some of the terrible pollutants into less harmful chemicals by forcing them through a mesh of materials known as a catalyst. Catalysts are made up of a number precious metals like rhodium, platinum, and palladium that use basic chemistry to break up or transform one chemical compound into another. Over extended periods of time, your catalytic converter will eventually lose all of its functionality and have to be replaced. If your vehicle or exhaust has sustained physical damage, the catalysts inside your catalytic converter may have physically broken apart causing your exhaust gases to simply go around the required chemical conversion.
While a lot of vehicles may only have one catalytic converter, typically located near the middle of the exhaust system, there are plenty of newer vehicles that utilize several catalytic converters. Some vehicles will have smaller cats up near the engines while other vehicles with dual exhausts will have converters on either side of the exhaust system. When you determine that you need to replace your catalytic converter for any of the reasons we have discussed, we bring you high quality catalytic converters and more from Walker.
Oxygen sensors are widely used sensors on vehicles these days. Simply put, an oxygen sensor reads the amount of oxygen in your vehicle's exhaust and sends a signal to your vehicle's engine control module which determines if there is too much or two little oxygen. It will then makes adjustments in the amount of air or fuel being injected into your engine in an effort to correct or balance your engine's ignition and emissions. If there is too much oxygen, then your engine is likely using too little fuel. If your oxygen sensors are reading a lack of oxygen, then it's probably due to too much fuel being pushed in, and right back out of your engine's combustion chamber. Basically, wasting fuel and emitting more harmful pollutants than your vehicle should.
Most vehicles will have multiple oxygen sensors that are strategically placed in your exhaust either before or after the catalytic converter. Through the evolution of oxygen sensor technology, these sensors have gotten more complex. Typically, if your vehicle uses more than one oxygen sensor, it may end up using two or three different styles of oxygen sensors. In other words, not all of the oxygen sensors on your vehicle are the exact same part number. If you determine that one or more of your oxygen sensors is faulty, we work with Standard and Bosch to bring you the correct oxygen sensors for your vehicle.
Exhaust Gas Recirculation. EGR. This tiny valve is located on your engine and is specifically designed to collect as much of the unburned fuel from your exhaust as it can and push it back into the engine's intake system. The EGR valve literally reuses your vehicle's fuel. A failing EGR valve will fail to re-circulate the unused fuel from your exhaust allowing it to flow through your catalytic converter and oxygen sensors which can lead to damaging either of those auto parts and increasing the toxicity of your emissions. We stock the EGR valve you need for your vehicle from two of the best brands in the business for engine parts, Standard and Delphi.
Positive Crankcase Ventilation. PCV. This is another tiny valve that helps control and reuse the tiny amounts of gases and fumes that escape the combustion chamber and into the crankcase of your engine. The introduction of the PCV valve corrects the original engine design that use to let these gases escape into our atmosphere. A failing PCV valve will not capture these gases and will ultimately allow them to eventually escape into our atmosphere. If your PCV valve has failed and you are in need of a replacement, we stock only the best from FRAM.
Believe it or not, broken or failing fuel caps are a leading cause of poor emissions and decreased fuel economy. When your fuel cap has lost its ability to maintain the pressure in your fuel system, hydrocarbons and fuel vapors leak from your vehicle. This not only decreases your fuel efficiency because you are losing fuel, but you harm the Earth's atmosphere by depleting the ozone layer and contributing to smog and pollution. Furthermore, you run the risk of fire or explosion. Given the right conditions, like a car accident, a simple spark can ignite the fuel vapors and the fuel in your fuel tank.
Replacing your fuel cap is perhaps the cheapest and easiest way to restore fuel efficiency and proper emissions with your car or truck, not to mention a great way to get to a $50 order if need that extra few buck on your order. If your current fuel cap is no longer doing the job, we stock a nice selection, both locking and non-locking from Stant and Gates.
On the subject of fuel efficiency and our effort to do our part to conserve Earth's resources, CarPartKings needs to give the auto part remanufacturers and their remanufactured auto parts their credit. The process of disassembling, cleaning, inspecting, and rebuilding with new seals and fittings, and reusing the non-wearable chunks of steel and iron that pass strict inspections is a way to save millions of all new auto parts from being made at all! This also means the remanufactured part costs less. You'll also get to do your part of by returning the part you are replacing on your vehicle. That gets you money back!
