If you own an older Mercedes-Benz, you most likely have the privilege of using an old-school Bosch K-Jetronic fuel injection system or one of its variants. Crude by modern standards, these injection systems were crème de la crème back in the day.
They were reliable and durable — something you could count on. However, as they aged, certain flaws became apparent. One such flaw was the fuel injectors. Today we’ll talk about Bosch CIS 0437502047 injectors and how they solve this problem.
What Is a Bosch CIS Fuel Injection System?
Bosch CIS (Continuous Injection System) fuel injectors have been around for quite some time and are still in use in many older cars. These fuel injectors were first introduced in the 1970s with Bosch Jetronic systems, and were used in many European cars of that era. They were an improvement over the carburetor-based fuel systems that were common at the time.
The Bosch CIS fuel injection system is a mechanical fuel injection system that uses an electronically controlled mechanical fuel distributor to distribute fuel to the injectors. This system works by using a fuel distributor that is connected to the fuel rail. The fuel distributor has a mechanical linkage that is connected to the throttle body. As the throttle is opened, the mechanical linkage in the fuel distributor moves, allowing more fuel to be distributed to the injectors.
The Bosch CIS fuel injectors are designed to provide a precise amount of fuel to the engine. This is accomplished by using a pintle-style injector that is controlled by a solenoid. The solenoid is controlled by the engine control module (ECM), which receives input from various sensors in the engine. The ECM uses this input to determine the proper amount of fuel to be injected into the engine.
One of the benefits of the Bosch CIS fuel injection system is its reliability. Because the system is mechanical, there are fewer electronic components to fail. This makes it a popular choice for many older cars that are still on the road today. However, one of the downsides of this system is that it can be difficult to troubleshoot when problems arise. This is because the system is mechanical and there are no error codes that can be read by a scan tool.
Steel vs Brass Fuel Injectors?
Original Bosch K-Jetronic fuel injection systems came with factory steel injectors. These were durable, reliable, and capable of withstanding the nominal fuel pressures without compromising the fuel spray pattern. Modern replacement injectors are usually made of brass. As with many things in the automotive world, this switch from steel to brass has caused a rift among car enthusiasts.
On one side, you have those who insist that steel injectors are the only way to go, while the other side feels that modern brass CIS injectors like the Bosch 0437502047 do an equally good job at maintaining good spray patterns. So who is right?
Overall, both sides bring up a few good points. Steel is a much tougher material than brass, making the original steel injectors much more resistant to deformation. However, steel is also prone to rust, which is one of the main reasons why modern fuel injectors of this type are made of brass. Another point in favor of brass injectors is the fact that they are new. When you get a fresh Bosch 0437502047 injector, you’re getting a part that was made recently using modern technologies and manufacturing processes.
At the end of the day, a new brass injector will always outperform an old steel one.
Bosch 0437502047 CIS Injectors — Are They Good?
The Bosch 0437502047 brass fuel injector is a popular fuel injector that has been used in many European cars from the 1980s and 1990s. This fuel injector is designed for use with the Bosch CIS fuel injection system and represents a modern alternative to the original steel injectors
As mentioned earlier, Bosch 0437502047 fuel injector features a brass construction. Brass is a durable and corrosion-resistant material that is ideal for use in fuel systems. This helps to ensure the longevity and reliability of the fuel injector. You don’t have to worry about corrosion, which was usually the problem with steel injectors.
Being the original creator of the K-Jetronic fuel injection system, Bosch has decades of experience with building reliable, durable injectors. On top of that, this company is constantly developing new manufacturing technologies, which are then used to improve older designs. When you buy the Bosch 0437502047 fuel injector, you’re getting an improved design that will give your vintage engine everything it needs to run smoothly and idle like a Swiss watch.
We recommend replacing all fuel injectors at the same time, especially if your engine is still running on the original steel ones.
