However, uncooled EGR designs do exist; these are often referred to as hot-gas recirculation (HGR). Cooled EGR components are exposed to repeated, rapid changes in temperatures, which can cause coolant leak and catastrophic engine failure. [9] [10] Unlike spark-ignition engines, diesel engines are not limited by the need for a contiguous ...
The interrupter can be either contact points or a power transistor. The problem with this type of ignition is that as RPM increases the availability of electrical energy decreases. This is especially a problem, since the amount of energy needed to ignite a more dense fuel mixture is higher. The result was often a high RPM misfire.
This causes an incomplete burn which causes the fumes to explode in the exhaust system along with an audible pop or bang sound. This is a result of working equipment, and is unlikely to cause damage. A fuel-injected engine may backfire if an intake leak is present (causing the engine to run lean), or a fuel injection component such as an air ...
This would reduce the flow of coolant through the oil cooler and cause higher oil temperatures. This sediment would also reduce the flow of coolant through the EGR cooler resulting in premature failure due to thermal expansion fatiguing the heat exchanging core. The early EGR coolers (2003-2004.5) were also susceptible to premature failure.
Hoka is one of the most popular brands of running and walking shoes out there today, and if you want a white sneaker that marries style and performance, we highly recommend the new Clifton 9.
We put the best air purifiers from Lenovo, Honeywell, Winix, and more to the test to see which held up best (and actually purified the air for you). See what our product scientist has to say.
Most people know that GLP-1 receptor agonist medications like Ozempic and Wegovy can cause relatively minor side effects like nausea and diarrhea. But new research confirms that more serious ...
To meet emissions standards, an EGR tube was placed in the intake manifold to reduce combustion temperatures. The 3800 Series II was on the Ward's 10 Best Engines list for 1995 through 1997. GM recalled 1.5 million vehicles with this engine on April 14, 2009 due to risk of fire from engine oil leaking under the valve cover gaskets onto hot ...
