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.

Keep Your Snow Plow Moving In Winter

Winter is upon us, in full force. With snow and ice on the streets, already, we can expect that December, January, and February will feature more of the same with the potential to halt traffic and even cause horrendous collisions. Equipment operators brave the cold weather and brutal conditions keeping the streets clear, but they need their diesel loaders, snow plows, and spreaders maintained carefully to ensure reliable service no matter what the weather has in store.

Snow removal personnel are up and at ‘em, bright and early, everyday; keeping the streets clear for traffic to pass. If their start is delayed, then the entire city suffers. There is much more at stake than just moving some snow and ice. Lives could be in danger.

The time tested adage says, “An ounce of prevention is worth a pound of cure.” Nowhere is this phrase more thoroughly proven than in the snow removal industry. Cold weather and diesel engines can be a challenging combination, but regular inspections and proper maintenance can give you the edge on the cold and save you dollars in the long run.

In addition to regularly scheduled maintenance, operators can keep their equipment running smoothly by performing daily inspections. A custom tailored and detailed daily inspection checklist for each vehicle is an excellent system for preventing small malfunctions from becoming huge catastrophes. Key points should include:

  • Checking and topping off all fluids.
  • Visual inspection of blades, teeth, hardware, hydraulic lines, and linkages.
  • Visual inspection of braking components, including master cylinder.
  • Check tire air pressure and tread condition, including minimum tread depth.

For all of your regularly scheduled maintenance needs, complete bumper-to-bumper service, as well as state-of-the-art diesel, direct injection, and turbo repair, you can count on Western Turbo, Winnipeg’s premier turbo diesel repair facility.

Turbo Charger Failure Checklist

Troubleshooting can be a daunting task for the average diesel owner, given the complexity of modern engine technology. But with a little understanding of how systems work, and what a functioning engine looks and sounds like, it’s not difficult to identify potential problems before they become expensive ones. Turbochargers, for instance, are generally only going to fail due to some form of mechanical damage or physical restriction, such as a blockage from debris. So it’s advisable to look for other likely culprits when failures other than these present themselves. The following is a useful checklist to help you troubleshoot failures in your turbocharger and locate their potential causes:

Excess Smoke

If you see excessive smoke coming from your turbo, look for restrictions around your intake, dirty air filter, seal or gasket leaks; inspect for cracks in the exhaust manifold.

Engine Runs Hot

Check for leaking hoses, seized valves, restrictions to air flow at compressor intake. Check air filter. Excessive heat can also be the result of incorrectly fuel injectors or injector pump. Check manufacturer documentation for proper settings.

Engine Lacks Power

In addition to a potentially damaged turbo unit, other possible causes for loss of engine power include incorrect valve timing, burnt valves or pistons; air leak between compressor and intake manifold, or intake manifold and engine. Check also for restrictions, foreign object blockage or leaks in exhaust system.

High/Excessive Oil Consumption

Check for: restrictions in turbocharger oil drain line or crankcase breather; worn piston rings, dirt build-up on impellers. Look for coking, or sludge build-up in turbo bearing housing.

Noisy Turbocharger

If the turbocharger is operating at a higher than normal noise level, or whistling, there are several possible causes, apart from damage to the turbo unit itself, most often some form of either air leak or restriction. Check for restrictions, leaks, or blockages as previously described, focusing first on the intake area, then look for blockages or cracks in the exhaust.
