Will EGR Delete Fix Your Major 6.4L Power Stroke Problems? A failed fuel -injection system and issues with the turbochargers will still leave you scratching your head.
Well, emissions control devices are not the only problem with this engine. In a similar manner, the 2 EGR Coolers outfitted on the truck have been known to clog or crack. The diesel particulate filter didn’t respond well to clearing soot through the regeneration process.
Problems with the emissions control devices, fuel system contamination, and leaking radiators have been common occurrences for owners of this Ford engine. Air is fed into the smaller turbo and fed into the larger one. It also has a dual VGT compound-turbo system. The engine was built with horsepower ratings of 350HP and a torque rating of up to 650 lb-ft. The engine itself was retired after the 2010 model year and replaced with a 6.7L Power Stroke. The 6.4L’s predecessor the 6.0L did not fair to well to critics because vehicle owners have plagued with issue an issue with their Ford truck. The 6.4L Power Stroke engine was introduced in the fourth quarter of 2007 for the Ford Super Duty models. The EGR valve is opened by a vacuum which is usually located under the throttle plates in the carburetor. The EGR valve is bolted to the intake manifold, and it must regulate a precise amount of exhaust gas into the combustion chamber otherwise an excess amount of gas will cause the engine to stall and run very rough. The exhaust gas also lowers the temperature in the combustion chamber so that less NOx is produced. The inert gas recirculates into the combustion chamber with fresh air/fuel mixture and will dilute or thin it out. However, within a year following California’s EGR mandate, the rest of the United States followed, through Federal Standards set out by the Environmental Protection Agency.įurthermore, exhaust gas inert and by that, we mean that it cannot undergo any further burning because 99% of the oxygen has already been burnt. California was the only state in America that required registered vehicles to have an EGR outfitted. In turn, the EGR valve reduces some of this nitrogen oxide from leaving the exhaust system and entering the air stream.ĮGR technology was first introduced in automobiles in 1972. Nitrogen oxide is responsible for creating photochemical smog which often blocks the skyline of many cities across the world, engulfing the tall buildings in a mist. Nitrogen oxide is a greenhouse gas the contributes to climate change. The result of burning air and fuel in the combustion chamber of an engine at high temperatures is nitrogen oxide. However, when the air is mixed with fuel and burns in the combustion chamber, the nitrogen in the air changes when the temperature levels surpass 2500 degrees Fahrenheit. On the other hand, nitrogen is an inert gas, and by that, it means it does not want to change or combine with any other elements – it’s happy just the way it is. Oxygen is essential to burn fuel in the combustion chamber. You may or may not remember from your high school science class that air is made up of 21% oxygen, 78% nitrogen and 1% of harmless gases. The primary task of the intake manifold is to evenly distribute the combustion mixture to optimize the efficiency of the engine.īut why do automobile engines mix fresh air with fuel? Is that not counter-intuitive to reducing pollution? The intake manifold is the part of an engine that supplies the fuel-air mixture to the cylinder. The exhaust gas recirculation valve mixes fresh air with fuel to return a small quantity of the exhaust gases into the intake manifold. Unfortunately, one of the methods of resolving this issue has been to suggest a 6.4 Powerstroke EGR Delete.ĮGR delete is the tampering-to-render-useless or outright removal of the exhaust gas recirculation valve.
Also if these 6.4 are neglected they will be nothing but a headache. We are starting to see lots of guys over 300k now with minimal issues. I will admit the 6.4 does have some downfalls but if taken care of properly there’s no reason it won’t last. The problem is the emissions for the most part and owners who think they are driving a 7.3 and maintenance can go by the wayside.
