What You Need To Know About BMW  Swirl Flaps and How To Solve The Problem With Them

What You Need To Know About BMW Swirl Flaps and How To Solve The Problem With Them

Swirl flaps are a BMW system that has been introduced to help burn the fuel mixture in the cylinder better due to the fact that diesel engines do not have throttle valves and it is not possible to adjust the air-fuel ratio. A diesel engine without vortex valves operates between a poor and a rich fuel mixture, because the only way to regulate it is through fuel injection. Design of the first generation swirl flaps that are made of made of metal. Unfortunately, swirl flaps are responsible for countless damaged engines and costly repairs due to design errors or metal fatigue. Once damaged, the cylinder sucks them in and causes great damage. This is how damaged valves damage the cylinder. Typical swirl flaps suction damage. The vortex valves are positioned in the inlet and are controlled by vacuum (DDE 4.0) or electrically (DDE5.0 / DDE6.4) by the engine ECU. Effects of malfunctioning valves: Swirl valves are stuck in open position: Deterioration of exhaust gas performance at lower speeds. Swirl valves are stuck in closed position: Approximate power loss of 10% at high engine speeds. How swirl flaps work: Performance characteristics: The vortex valves are in the closed position, at low engine speeds and small amounts of fuel injected (controlled by the ECU card). They open under the following conditions: coolant temperature <14 ° C OR * fuel quantity> 24 mg OR engine speed 2250 rpm OR inlet air temperature <-5 ° C BMW and Pierburg have decided to produce diesel engines with metal vortex valves. The speed at which the pistons in the diesel engine operate is at least 60 rpm, so a sucked vortex valve will break and cause a number of damages inside the engine. In most cases, one or more pistons are severely damaged, as a bonus you get valves, in some cases a head or turbocharger. And this combination with a BMW engine is like a cumulative jackpot 🙂 In 2004, BMW began work on the problem and improved the design, however, a number of owners reported ongoing problems in this area. The solution to this problem is by removing the vortex valves and plugging, which does not affect the performance of the engine and at the same time, you can safely pass the exhaust test. Engines: M47 (136hp VP44 fuel pump) has no valves. M47N common rail engine (including M47N / M47TU / M47TUD20) (150hp. Face lift model from 2001 -) has valves. M57 engines (M57D) (525d & 187hp. 330d) cars with manual transmission do not have valves, but those with automatic have. M57N engines (M57TUD) (525d & 330d 204hp) have vortex valves. Ruined swirl flaps: The plugs that replace the vortex valves are easy to find on the internet, but you can also find them here on our website. Typical plugs: Disassembly of vortex valves: The vortex valves can be safely dismantled and in most cases if they are removed properly no loss of power is felt.
