Know Your Turbocharger


A turbocharger is like a superhero for diesel engines. It’s a device that helps the engine breathe better by forcing more air into its combustion chamber. This air assists the motor in burning more fuel, which produces more power and torque.

A turbocharger works like a fan that’s powered and extracts energy from the exhaust gas and uses it to drive the compressor and overcome friction. The compressor breathes in the fresh air and compresses it, making the air denser and full of oxygen. This thick air goes to the engine’s combustion chamber, which helps burn the fuel more efficiently. Need turbocharger expertise? Visit a diesel mechanic shop for optimal performance!

Turbo is Out, How to Power Up the Turbo Again


This is how you properly destroy your turbocharger (Do you even want to do that?) : If you encounter your turbocharger doesn’t have enough oil, it can harm the bearings. Little lubrication can cause the shaft to move around too much and the compressor or turbine wheel to touch the housing. It can also damage the thrust bearing and create too much heat for the center section to handle. 

Dirty oil can cause problems for a turbocharger. Problems can happen when the oil is not maintained correctly or when the engine has coolant or fuel leaks. It can also occur when internal engine parts break down and leave debris in the oil. Using dirty oil can cause the same problems, except for excessive heat. The thrust bearing is essential because it keeps the shaft from moving too much. It sits between the compressor wheel and the shaft and needs oil to work correctly. If it comes into contact with the shaft, it can cause damage and eventually lead to the compressor wheel touching the housing. When a bigger, heavier compressor wheel is installed, it can shorten the life of the thrust bearing even more.

Also referred to as turbo bark or chirp, a compressor surge occurs when intake air reverts out of the compressor. It’s most often experienced when an elevated boost is produced and then cut off abruptly. The noise you hear is the compressed air trapped in the intake with nowhere else to go but back out the way it entered the turbo. Surging is extremely hard on the compressor end of the turbo, and prolonged surging will eventually beat the thrust bearing to death. Blow-off valves are usually used in high-surge applications. If violent enough, surging can explode a compressor wheel or the turbo.

Extreme heat can also destroy anything except for glass-making and metal works. Well, the same goes for killing the turbochargers. Prolonged exposure to high heat will eventually take its toll on the turbine side of the turbo. Common failure points are because of the heat stresses, the cracks in the turbine inlet flange, damaged edges of the turbine inlet volutes, and shape changes of the tips of the turbine wheel blades of the turbo.

Common causes of excess heat from the turbo are high performance, a restricted exhaust system, a damaged intercooler, or a dirty air filter. It’s been encountered that heat will damage some internal parts in the engine before it can do considerable damage to a turbine wheel or the turbo. Still, it happens sometimes.

Professional technicians from a reputable diesel mechanic shop can help you undo these kinds of problems occurred to your turbocharger.

Maintain Your Diesel Power and Maximize Your Engine


Power is the main attraction of owning a diesel-powered vehicle. That is why many drivers opt to have a diesel-powered car in their garage. To maintain your diesel power like a roaring Lion, taking good care of your engine is a number 1 priority. Diesel-powered engine is different from gasoline-powered engines. 

Diesel powered engine uses engine coolant as the engine heats up high. You, as a driver, need to monitor the condition and level of engine coolant every time before you drive.

Like a comparable gasoline engine, diesel motors produce tons of heat during operation. The coolant circulating within your diesel engine absorbs heat from the engine, lubricates the water pump, and keeps your diesel from overheating under extreme coercion. Check the coolant level regularly and replenish it as needed. Open the hood, and locate the coolant reservoir, to check if your engine is running on sufficient coolant. 

Religiously (even if you are not religious) change the oil of your diesel-powered engine. It doesn’t matter if you have a gasoline or diesel car. Regularly changing the oil is cheap insurance against costly repairs. Professional mechanics highly recommend diesel-powered vehicles change the engine oil every 5,000 to 8,000 kilometers. It also depends on the type of vehicle. The golden rule is always to know your owner’s manual. Cars that run on gasoline and use fully synthetic oil can operate for 10,000 to 12,000 kilometers before requiring an oil change. 

You have to replace your diesel-powered engine fuel filters regularly to maintain the power of your engine. Older versions of diesel engines have only one fuel filter, but now most modern diesel motors have two fuel filters, a primary, and a secondary fuel filter. When it comes to diesel engines, cleanliness is next to Godliness. Oxygen is diesel engine’s best friend. Many people don’t know that an excessive amount of dirt and grime can destroy a diesel-powered engine before the time before it malfunctions.

Replace the air filter of your diesel-engine-powered car because oxygen is the diesel-engine’s best friend. Like how the fuel filters protect modern diesel engines from dirt and debris, the air filters do the same job as it filters the air coming into the car engine from dirt, debris, and foreign objects that would lessen the diesel engine’s power. If you have a diesel car, replacing the air filter every 25,000 kilometers is a good practice as an owner. Visit a diesel mechanic shop for expert assistance!
