How to Tell Whether You Have a Bad Diesel Fuel Injector

All diesel engines use fuel injection. The first mass-produced diesel car, the Mercedes-Benz, used fuel injection as early as the late 1930s. Fuel injection was first introduced in gas-powered passenger cars in the 1950s. By the 1990s fuel injection replaced carburetors altogether in passenger cars. The chief difference between carburetion and fuel injection is that the former sucks the fuel into the engine whereas fuel injectors atomize the fuel by injecting it under high pressure through the nozzle.

Fuel injectors consist of two main components, the nozzle and the injector body. If either of these gets damaged of clogged, it compromises the overall performance of your vehicle. One of the keys to smooth, efficient performance is to make sure your injectors are clean. 

A story in yesterday's EconoTimes addresses this issue of injector performance. It's titled 7 Signs That You May Have a Bad Diesel Fuel Injector. Here are the seven things to pay attention to, according to this story. 

1. Engine Misfiring or Vibrating
Does your vehicle frequently misfire? Do you experience a delay when you press the accelerator? This could be a sign that you have an injector issue.

2. Check Engine Warning Light
There was a time when check engine lights were more of a nuisance than accurate indicator of trouble. I had a mechanic once tell me that the solution was to put a postage stamp over it because they were too sensitive. Nowadays, they are invaluable. A good mechanic can take a reading on the codes and tell you precisely which cylinder injectors are causing a problem. You should first check your glow plugs before going the extra mile to check the injectors.

3. Rough Idle
According to EconoTimes, if you have a change in the feel of your vehicle when idling, it may be a clogged injector. It may also be an clogged air filter, so you may want to start there, especially if you drive on dusty roads and haven't checked it in a while.

4. Engine Stalling
If your engine stalls for no apparent reason, it may be because the engine is not getting the fuel it needs. Insufficient fuel will cause the engine to stall out. When injectors are badly clogged, this will be a consequence, though it can also be caused by a fuel leak where the injector is connected to the fuel lines.

5. Diesel Fuel Smell
If you have a diesel fuel smell while driving, this is very likely a faulty injector leaking. You need to take care of this right away. 

6. Poor Fuel Economy
Another reason to keep your injectors clean is because for it is essential for optimal engine performance and fuel efficiency.

7. Bad Emissions
If you live in a state with required vehicle inspections, you may fail an emissions test and wonder why. It is quite possible you have partially clogged injectors.

One way to address these issues is to include fuel injector cleaning as part of your routine engine maintenance regimen. Just as you have become disciplined about routine oil and filter changes and checking fluids, so you will want to incorporate routine fuel injection cleaning. 

Diesel fuel injection cleaners are fairly essential to longer service life from your engine. There are other fuel additives that serve specific purposes as well including deposit modifiers, corrosion inhibitors, freeze depressants and more.

Two fuel additives from Champion Brands that you may be unaware of are Diesel Flo Fuel Conditioner and Power Plus Diesel Fuel Additive with Cetane.  The latter will not only remove deposits but also reduce emissions, provide corrosion protection, increase cetane and improve power, a multi-functional diesel additive for today's high-pressure common-rail injectors and modern diesel fuels.
