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.

Champion Oil's Winter-Blend Diesel Flo Fuel Additive Gets an Upgrade

It's wintertime and Champion Oil has been active making sure our diesel equipment is being taken care of with a variety of new or enhanced products. This week Champion announced the launch of an enhanced "winter-blend" Diesel Flo Fuel Additive with Cetane.

“Most diesel enthusiasts use fuel additives from time to time, most likely in the winter to prevent gelling,” stated Karl Dedolph of Champion Brands, LLC.  “But there are other diesel enthusiasts or fleet owners that regularly treat their fuel with additives. Some use detergent additives or lubricity agents to make up for the loss of sulfur in diesel fuel, which disappeared 15 years ago under an EPA mandate. Others use fuel stabilizers to offset the effects of minimal use or storage, and cetane improvers to optimize combustion with the intent to reduce emissions and increase horsepower.”

Dedolph went on to cite a number of problems that can be avoided or resolved by means of additives. “One of the most common problems, and perhaps the most easily avoided," he said, "relates to the condition of the injectors. By using the correct fuel additives, injector damage due to water and internal diesel injector deposits can be prevented. When a lubricity additive is used, the life of the injector is increased. Best method is to examine the Bottom of Form condition of an injector is when tearing down the engine. If it didn’t fail over its expected replacement life, perhaps that’s the result of the additives you used. “

Another problem that additives can address is fuel filter plugging.  “If you suffer from fuel filter plugging, an additive can help dissolve the asphaltenes. These are high-molecular-weight hydrocarbons that are usually found on the bottom of the crude. They can also be formed in ultra-low-sulfur diesel fuel from the heat created by higher pump pressures inside the fuel system and returned to the tank from your fuel pressure regulator.”

Fuel additives can help dissolve the asphaltenes in the fuel and also prevent them from forming and plugging filters, he explained, adding, "Many diesel owners suffer from the effects of a low cetane rating within the fuel that causes poor fuel economy and hard starts during the cold months. A good fuel additive should boost the cetane number and solve each most of the fuel and filter related issues.”

The new, more robust formula found in Champion's Diesel Flo with Cetane (part #4183) is a premium diesel fuel anti-gel and de-icer designed to prevent operability issues in diesel fueling systems at sub-zero temperatures. The product disperses and removes water from diesel fuel and prevents icing of fuel filters.  Cold-flow improvers prevent aggregation of diesel wax crystals, allowing for lower pour points, cold-filter plugging points (CFPPs), and gel temperatures in low-sulfur and ultra-low sulfur diesel fuels and biodiesel blends.

This is Champion's most concentrated formula ever,  boasting the following features and benefits:

• Reduces solvent load and decreases cost-to-treat
• Performs in low sulfur and ultra-low sulfur diesel and biodiesel blends
• Reduces cold-filter plugging points by as much as 20°C (36°F) in untreated fuels
• Disperses and removes water from fuel
• Reduces the pouring point and gel temperature of fuel
• Helps prevent fuel filter icing and cold-filter plugging
• One quart treats up to 250 US Gallons of diesel fuel

Getting Your Diesel Truck Ready for Winter

Photo courtesy Chevrolet

It's Black Friday. It's nice to have a long weekend to get our vehicles ready for winter. What follows are a few areas to focus on, extracted from an article by Whitney Russell that I saw this week at The NewsWheel.

1) The Battery
As you head into winter you may wish to test your battery to see if it is ready for Jack Frost. According to NAPA auto parts, battery strength is reduced by 35% at 32 degrees and 60% at zero. The time to deal with an older battery is before the season, not when you get stuck somewhere and need cranking power.

If you live up north you probably know a little about the tricks diesel owners use in the winter time, but if you've just moved here from another part of the country you may want to think about getting a block heater, if your truck doesn't already come equipped. (Heated seats are nice, too, but they won't help get your truck started.)

2) Anti-Gel Fuel Additives
It depends on where you live, but for those unfamiliar it can really get frigid in winter the further North you go. Sometimes someone in Florida goes to visit family in Maine or Toronto, and is unaware of how cold it can get. You should be prepared with a suitable fuel additive to keep it from gelling before it reaches its cloud point, the point at which wax begin to form and inhibit flow.

3) Switch to Lighter Weight Oil
Unless you're a newbie you know how viscosity makes a difference between seasons. If you need help selecting the right diesel oil for your truck, you can always Ask Jake. (Hit the white Ask Jake button on the right here.) 

4) Fuel Filter
The author suggests that if it's been a while since you replaced the fuel filter, this would be a good time to deal with it. We're also reminded that some trucks have two. Replace both.

The article is basic, but a good reminder that it's that time of year and winter's coming soon... or has already arrived, depending on where you live.

The article ends with links to more info on block heaters and how to protect the exterior of your vehicle from road salt. Don't know what road salt is? It's not for your grits. 

Here's a link to the article in full. Hope you've recovered from your feast yesterday and had a happy Thanksgiving.
