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.

Because we understand diesel engines better than anyone else, we will diagnose and repair the root cause of your problem, not just the symptom.

Engine Oil CheckUp Kits and No Spill Systems at your Diesel Service Centre!

IAmDIESEL at Western Turbo is the Winnipeg area diesel expert for all kinds of service, including the tasks that you do yourself.

Diesel engines have specific needs, and foremost among them is lubrication. Because compression ratios are higher in diesel engines, and because turbocharged engines depend on the oil to lubricate and cool the turbo, the condition of your engine’s oil has a huge bearing on its health and well-being. IAmDIESEL and Western Turbo provide two products specifically designed to help diesel owners keep the lifeblood of their engines flowing:

Engine Oil CheckUp Kits
Engine oil analysis in a laboratory can be expensive, and results can take a long time. Engine Oil CheckUp kits, on the other hand, are inexpensive and fast, and provide comprehensive results regarding the condition of your engines oil. These results can be used to ensure that your oil isn’t unduly dirty, or contaminated with fuel, water or glycol (antifreeze), which can be a warning sign that something serious is wrong with the engine itself. This engine fluid test is a one-step diagnostic tool and test kit results will indicate the presence and concentration of contaminants. You can easily administer an Engine Oil CheckUp Kit yourself in about 30 minutes by placing a single drop of oil on the test medium paper, then reading and interpreting the results.

No Spill Systems
No Spill Systems simplify oil changes, and eliminate many of the problems associated with improperly installed or damaged oil drain plugs. There are 3 styles, the Standard System, the Compact System, and the Speed Click System, each one with a custom torque setting. They make the job easier, are compatible with all vehicles, work with gravity or suction drain methods, and reduce the chance of an oil spill, which is messy and harmful to the environment. Regular maintenance of your engine is a necessity. With a No Spill system, it’s easier than ever to keep those oil changes on schedule!
