Have You Checked Your Oil Supply For Your Diesel Turbocharger Lately?

There are many little things that you can do to make your turbocharger last longer.  One of the simplest things to do for preventive maintenance is to check your oil and fluid levels. If the supply is not sufficient to properly lubricate the system, a lot of bad things can happen.  At Western Turbo, we see many damaged turbochargers due to insufficient oil supply.

Here are some attributes that lead to damage due to insufficient oil supply;

 

  • Re-fitting a turbocharger without adequate priming
  • Long periods of non-use
  • Broken or restricted oil feed pipe
  • Low engine oil pressure due to malfunctioning lubrication system
  • Low or no oil in sump
  • The use of sealants, which can restrict the oil flow
  • Not priming a replacement oil filter with new oil.  If this cannot be done, then crank the engine with no fuel to establish oil pressure.
  • Do not exceed idle conditions until oil pressure is established

Regular maintenance by Winnipeg’s largest diesel service centre should ensure that your diesel turbo charger is in top working order.   Western Turbo can set you up on a preventive maintenance program for your individual diesel or fleet requirements.  Whether you are in Winnipeg, or rural Manitoba, give us a call for you next service.

Clean Oil Key to Keeping your Turbochargers in Top Condition

Do you feel that your diesel engine is not giving you top performance?  Your turbocharges may not be functioning properly due to damage from dirty oil.
Dirty oil damages the turbocharger by causing heavy scoring of critical bearing surfaces.
To avoid damage, oil and filter should be of a quality that is recommended by an OEM.  These should be changed when a new turbocharger is fitted by Western Turbo.  After that, regular oil and filter changes should keep your turbochargers in great condition.
Dirty oil damage could result from:
–  Blocked, damaged on poor quality oil filter
–  Dirt introduced during servicing
–  Engine wear or manufacturing debris
–  Malfunctioning oil filter by-pass valve
–  Degraded lubrication oil.
Regular maintenance by Winnipeg’s largest diesel service centre should keep your turbochargers spotless.  Western Turbo can set you up on a preventive maintenance program for your individual diesel or fleet requirements.  Whether you are in Winnipeg, or rural Manitoba, give us a call for you next service.

Counterfeit Turbochargers – Who Would Have Thought?

When we think of counterfeiters, we picture a green-visored man, his hands covered in ink, sitting in a rented hotel room printing out $50 bills.

Or cheap imitations of luxury watches, made out of tin and guaranteed to keep time for the next five minutes.

We generally don’t think about counterfeit turbochargers, but they’re part of the emerging problem of misrepresentation enabled in large part, by the Internet.

You would be unlikely to purchase diesel engine components out of the back of a van in the parking lot of your local shopping mall, or from a sketchy looking character in an alley, but you might be tempted to order from a very legitimate looking website offering a great deal on a product with a stellar reputation.

Beware! A counterfeit turbocharger unit may look and seem like “the real thing”, but is highly unlikely to perform in the same way. A knock-off turbo is likely to be unable to withstand the same use as the part it’s imitating, and could fail catastrophically. This failure could cause damage to your engine or other parts of your vehicle. In a worst-case scenario, grenaded parts could exit the engine compartment and actually cause physical harm to the driver, mechanic, or an innocent bystander.

Like that luxury item sold for $20 in a back alley, looking like the real thing and “being” the real thing are two different things. Always buy your parts from a reputable distributor and if a deal seems like it’s too good to be true, it probably is. If you think you might have purchased a counterfeit turbo, make sure you have it inspected by someone who can tell you if it’s genuine or not right away, before it fails.

Why Did Your Turbocharger Die?

A turbocharger is simple in concept, but complex in operation.

In a nutshell, a turbocharger uses exhaust gases produced by the engine, which are pushed out of the engine at a velocity that corresponds with the speed of the engine’s rotation to push fresh air into the engine. The faster the engine “revs” the higher the volume and speed of the exhaust that escapes it is. Exhaust consists of air and the by products of fuel combustion (carbon monoxide, and a lot of other chemicals).

In a normally aspirated engine, air is taken in at atmospheric pressure. In a turbocharged engine, air is pushed in to the combustion chamber under pressure. Because the air is compressed, more fuel can be introduced into the engine while still maintaining the ideal mixture ratio between air and fuel. Simply put, being able to put more fuel into the engine results in more power.

Because the exhaust gases would be emitted anyway, harnessing them to increase performance also increases efficiency. The turbocharger plays a big role in making diesel engines the powerhouses that they are.

Unfortunately, the high temperatures and speeds involved in a turbocharger can be hard on it. The turbine is the component that hot exhaust gases push against to drive the unit. It’s subject to extremely high temperatures, and speeds up to 150,000 rpm. The compressor wheel “squeezes” air into the compression chamber. When air is compressed, it gets hot. Even at the “cool” end of the turbocharger temperatures can exceed 200 degrees Celsius.

The turbocharger needs a healthy supply of engine oil to lubricate its moving parts, and to help cool it. Often, an impediment to oil circulation and/or dirty oil, can cause the turbocharger to fail. In fact, short of component failure in the turbocharger, nearly every turbocharger failure is caused by something else in the engine not working correctly. Air and gas leaks, worn piston rings, clogged exhaust, carbon build-up and a hundred other things can cause turbocharger failure. When this is the case, simply replacing your turbocharger may appear to solve the problem, but it will likely reoccur in a relatively short time.

Diagnosing Problems with your Diesel Turbocharger

An engine is designed to burn a fuel-air mixture to produce mechanical energy. A significant difference between a turbocharged diesel engine and a traditional naturally aspirated gasoline engine is that the air entering a diesel engine is compressed before the fuel is injected.

Turbochargers are a type of forced induction system. They compress the air flowing into the engine, which lets the engine squeeze more air into each cylinder, resulting in the ability to allow more fuel into the cylinder. More fuel equals more power in each cylinder.

Conceptually, turbocharging is rather simple. However, the turbocharger is critical to optimum performance and overall operation of the diesel engine, so if something goes wrong, it could lead to engine failure or component damage.

Turbo Trivia Part 2 – Common Turbocharger Problems

A turbocharger is a finely balanced system.  Very high temperatures and extreme rotation speeds mean that it needs to be one of the most carefully engineered systems in your vehicle.  It’s a highly evolved piece of technology that, despite the extreme demands placed on it, will likely last as long as the rest of your vehicle if properly maintained.  Quite often, a turbocharger failure is a symptom of an underlying engine problem that will need to be addressed before simply replacing the turbo unit, or it will repeat itself.  Here are some more symptoms and their possible causes:

Insufficient Power or Boost Pressure Too Low

If a turbocharger doesn’t produce enough boost pressure, it won’t work.  There can be any number of causes of this condition, from a worn engine to a broken or damaged turbocharger bearing.  Low pressure can also be caused by leaking lines or gaskets (allowing pressure to escape before driving air into the cylinders, improper filter maintenance, and a worn or sticky poppet valve can also cause this condition.

Oil Leakage at the Compressor

There can be a whole lot of explanations for leakage at the compressor.  One of the problems we find most often at Western Turbo to explain this problem is a buildup of combustion by-products (coke and sludge) in the turbocharger housing.  The reasons for this buildup can be many – a dirty air filter system, exhaust that leaks upstream of the turbine, some kind of kink or clog impeding oil flow to the turbine.  Sometimes this buildup is caused by failure of the turbocharger bearings themselves, or a loss of compression in the engine.

Oil Leakage at the Turbine

Turbine oil leakage causes mirror those problems that cause the compressor itself to leak.  The first thing to check for is a buildup of sludge inside the casing of the turbocharger.  If present, look for the underlying cause, which is usually a problem with oil flow to the turbocharger.

Noise from the Turbocharger

In the case of a noisy turbocharger unit, it’s imperative that you trust your ears and look into the cause before a unit failure results.  Often, if you catch it early, you can prevent extensive damage to your turbocharger.  The leading causes of increased noise from your turbo unit are too little flow of air or oil, or foreign material in the bearings.

If you’re experiencing turbocharger difficulties, consult Winnipeg’s turbocharger and fuel injection expert, Western Turbo.  We do more than just maintain and repair turbocharger units – we find the root cause of the problem and correct it, so you won’t just have a recurrence.

Turbo Trivia Part 1 – Common Turbocharger Problems

While modern turbochargers are highly evolved systems that provide relatively trouble-free service for the lifetime of your engine, it’s good to be able to recognize the symptoms of turbocharger troubles and their causes, to simplify repair of one of your vehicle’s key performance improvement systems.  Very often, a turbocharger problem is the result of an issue elsewhere in the system, and will recur unless the underlying issue is addressed.

Exhaust Smoke – Black

There are a lot of issues that can cause excessive black particulate in your vehicles exhaust.  Look to the air filter system and the supply of oil to the turbocharger, as well as damage to the unit itself.  Often the turbine housing, flap, or turbocharger bearing will have failed, or the boost pressure control swing valve isn’t closing properly.  This problem can also be caused by problems elsewhere in the engine – worn valve guides, piston rings, or cylinder walls can cause blow by that manifests itself as black smoke.

Exhaust Smoke – Blue

Blue smoke can be caused by a number of factors, including overall engine wear.  Turbocharger related causes of this symptom include dirty compressors, excessive exhaust flow resistance, or bearing damage.  Look out for dirty air filter systems, or a buildup of coke and sludge buildup in the turbocharger housing.

Excessive Boost Pressure

If your boost pressure is too high, the likely cause is in the swing or poppet valve or the associated pipe assembly to it.  It could also be caused by a fuel injection problem.

Defective Compressor or Turbine Wheels

The high-speed spinning parts of the turbo unit can be damaged by excessive heat and friction caused by improper lubrication.  If these parts are worn or broken, they’ll need to be replaced.

Oil Consumption

High oil consumption can be caused by a number of factors, including worn out engine components like piston rings, valve guides, and cylinder walls.  It could also be a symptom of something as simple as a dirty air filter system, or an improperly vented crankcase.

Turbocharger Care and Maintenance

One of the most efficient ways to increase the power output of any engine, gasoline or diesel, without increasing the size and weight of the engine, is to add a turbocharger.

Turbochargers are used on all kinds of vehicles – racecars and big diesel truck engines both commonly employ them, because they’re often asked to provide maximum horsepower to get their jobs done.

Turbochargers improve engine performance by using the engine’s exhaust to power a compressor, which will force air into the cylinders of the engine, so that more fuel can be added while still maintaining the optimum ratio for efficient combustion.  Because more air and fuel are in the cylinder, the explosion produced on the power stroke provides more energy.  The performance improvement provided by a turbocharger far outweigh the increased load the system puts on the engine’s exhaust.

Turbochargers have been in use for a long time, and the systems are quite evolved.  You can generally expect your turbo system to last as long as your engine does.  There are, however, some considerations you need to make surrounding maintenance of a turbocharged engine.

The main problems that confront turbochargers are heat and lubrication related. Because of the extremely high speed that the turbo is required to spin at, conventional bearings would fail very quickly.  Turbochargers use a fluid bearing – a thin layer of oil that separates the mechanical parts to prevent wear and keep the moving parts in the compressor or the turbine cool.  Most turbocharger failures are caused by inadequate lubrication, or foreign particles in the oil.  This means that the key maintenance requirements for a turbocharged engine are oil changes at prescribed intervals, oil and air filter system maintenance, and oil pressure control.

Insist on OEM

It has been said that stock runs best. Simply put, low grade aftermarket parts are no particular bargain if they don’t perform properly or possess the same degree of longevity that original equipment manufacturer (OEM) parts provide. When it comes to your livelihood, as it pertains to your turbochargers, insist on OEM replacement parts purchased through a reputable source.

Most modern diesel engines are turbocharged. A turbocharger allows the engine’s horsepower and torque to be multiplied through forced air induction. Inside the turbocharger housing is both a turbine and an air pump. Both are driven using the same shaft. Spent exhaust gases, escaping the compression chamber, are used to drive a turbine at very high RPM. As the exhaust turns the turbine, the air pump impeller draws high-volume, low-pressure ambient air into the engine. The ambient air is drawn in through the front air-dam and the intercooler, in order to ensure that a steady source of cooler, denser air is available to the air pump. This additional air induction allows the engine to burn an increased amount of fuel, resulting in more horsepower and torque.

Why buy OEM Turbochargers?

Aftermarket turbochargers aren’t manufactured to the same stringent specifications as OEM one, neither are they made from the same top-quality steel and components. Turbochargers are by nature very powerful, yet they operate under very delicate circumstances. The turbine wheel and housing must be meticulously machined and assembled; tolerances between the impeller and housing can be well under several thousandths of an inch. Extreme temperatures from the exhaust, which drives the air pump, coupled with these very close tolerances demand that the turbocharger be designed, engineered, and manufactured to the most rigid guidelines. You just don’t get that type of quality anywhere but OEM for turbochargers.
