This different chemical makeup allows the combustion chamber to stay up to 150 degrees Celsius cooler, which produces cleaner exhaust and improves overall engine performance. Not only that, but the exhaust has a different chemical makeup than fresh air. First, it optimizes the fuel to air ratio without pulling in extra air from the intake. Recirculating the exhaust does a few things for overall performance. EGR Valve stands for exhaust gas recirculation valve, which breaks down exactly what it does. The EGR valve takes specific amounts of exhaust and recirculates it back to the combustion chamber.

If you have a check engine light on for a faulty EGR valve, keep an ear out to see if you can hear any knocking. ![]() While this won’t always happen if you have a faulty EGR valve, the chances go up dramatically if the valve is stuck closed. Keeping the combustion chamber at a lower temperature prevents the fuel from igniting before it should. One of the lesser-known perks of the EGR valve is that it actually reduces engine knocking. RELATED: Rough Idle Causes & How to Fix it 6. That’s because the EGR valve is typically open then as it recirculates exhaust to lower the overall temperature of the combustion chamber. However, if the EGR valve is stuck closed, you’ll notice more problems while idling after the engine has already warmed up. That’s because usually, the EGR valve starts in the closed position. If your EGR valve is stuck open, then you’re going to get a rough idle, especially when your vehicle hasn’t warmed up yet. You might also notice that your acceleration has become jerky or rough. You’ll notice the problem more at lower speeds if the EGR valve is stuck open and at higher speeds if the EGR valve is stuck closed. Not only does an optimized engine improve fuel economy, but it also improves engine performance. While this might sound like a great symptom, it can damage your engine. One of the advantages of this is that it reduces the combustion chamber’s temperature and improves efficiency.īut when the EGR valve is stuck open, the engine will suck in air that is already measured by the MAF sensor, leading to a lean air-fuel mixture and a reduction in fuel consumption. Your EGR valve works to send the right amount of exhaust back to the combustion chamber. You might notice slightly more smoke when the EGR valve is bad, but this isn’t very common. In fact, if you have a faulty EGR valve, your vehicle will most likely fail an emissions test. Your EGR valve’s primary purpose is to reduce emissions, so you can expect that if it’s not working correctly, your overall emissions will increase. For instance, you might get a check engine light that indicates excessive exhaust chemicals or misfires, even though the problem stems from a faulty EGR valve. ![]() While the check engine light will usually point you straight to the EGR valve, it is possible that it might come on due to a symptom instead of a cause. Whether the EGR valve is clogged, stuck open, or stuck closed, you’re going to get a check engine light. Browse through our motor oil online listing today.There are tons of sensors monitoring your emissions, engine performance, and even the EGR valve’s performance. ![]() You can even find a selection of specialty and race oils in our collection. Best of all, we stock a range of leading brands of engine and diesel oil online and in stores across Australia. It’s advised that car owners should change their engine oil approximately every 8000km, depending on how old your engine is and the way that you drive. Motor oil lubricates the parts and absorbs heat, which allows all of the components to move together smoothly and effectively, without letting your engine overheat.īy regularly changing your engine or diesel oil before it wears out, saves you the trouble of your engine overheating or worse. This movement causes friction in the engine, which leads to excessive heat. Tip-Top EngineĪll cars and trucks have moving parts in their engine, which rub and move together when your vehicle is in motion. Which is why it’s important to keep a bottle or two of your favourite car oil brand as a reserve, because it’s that easy to change it yourself. It’s an integral element that keeps your engine functioning, without it your engine could overheat and cause irreplaceable damage. Whether you know everything about cars or not, one crucial part of routine maintenance is replacing your engine oil and filter. ![]()
