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. Click here for tips on troubleshooting common problems that you may be experiencing with your diesel turbocharger.

At Western Turbo, We Know Injectors!

Western Turbo and Fuel Injection is your Winnipeg area expert in repair and maintenance of diesel and gasoline injection systems. We’ve been in the business since 1979, and have consistently shown ourselves to be committed to our customers. Through amalgamation of other facilities, Western Turbo has built itself into the premiere supply and repair facility in the area.

As an expert in diesel technology, we have developed a strong knowledge base and have invested heavily in equipment to service fuel injection systems. Because our customers need us to have it, we invested in a Bosch EPS 815 Common Rail Injector Tester, the only equipment certified by Bosch to test their Common Rail Fuel Injectors and one of two such machines in Canada.

This tester allows us to perform diagnostics on Bosch Fuel Injection Systems while preserving our customers manufacturers warranty.

Our expertise extends to other fuel injection technologies as well. Many automobile manufacturers have recently begun incorporating Gasoline Direct Injection technology into their cars, which basically brings the technique of injecting fuel directly into the vehicle’s cylinders, which is how it generally works in diesel engines to their gasoline powered counterparts. There are significant benefits in terms of fuel efficiency and power output in this technology. The downside is that many repair facilities lack the experience and equipment to deal with these specialized system.

Not Western Turbo. Because we’re diesel experts, we’ve been around the block with Direct Injection. Many shops will swap in a whole new set of injectors when fuel supply problems turn up, which can be extremely wasteful in the event that only one or two of them require replacement. Most of the time, injectors can be returned to use after a thorough cleaning, but you need the equipment and expertise. We have both.

Western Turbo has a state-of-the art repair facility at 325 Eagle Drive in Winnipeg.

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.

The next time that you have a problem with your turbo diesel, trust the professionals at Western Turbo to provide you with quality parts and experienced, courteous service.
