A Guide to Diesel Engine Tuning

Diesel engines have had a long history of incremental improvements. The efficiency, power, and torque you can get from a modern diesel engine are on another level compared to the first models.

Tuning a diesel engine is not a hard task for experts. But if you’re an amateur automobile owner, please stay away from your engine and let a professional handle repair, maintenance, and tune-up tasks.

While tuning your diesel engine, you might not fully comprehend its rev range. However, when driving, you’ll feel a world of difference.

Diesel engines are the perfect option when it comes to great economy and power. But tune-ups also carry risks. So proceed with caution:

The Tune-Up

Getting your diesel engine tuned is not only great for fuel consumption, but will also allow you to extract more power from the vehicle.

What’s more, tune-ups cost you way less than the extensive repairs that result from a lack of maintenance.

Inspect The Injector Pumps

Parts of the injector pump experience wear and year over time. The seals tears if not taken care of properly.

As a general rule of thumb, most injector pumps will require a replacement after the vehicle has been used for 90,000 to 120,000 miles. Some injector pumps may last longer than this limit, but most of them will have to be replaced. If you aren’t sure if your injector pump has worn out, you can call in for an expert to check it for you.

The Injectors

Metal rubbing on metal can only last so long without lubrication. In the absence of an appropriate lubricant, the injectors will get jammed due to the carbon that results from the cylinder firing. When you’re getting the injector pumps tuned up, it is recommended that you get a new pair of injectors installed as well.

The Valves

The valves will stretch or compress over time. Each of these valves needs clearance and adjustment over time to open and close properly. This is a necessary step to take in the tune-up process to ensure that your engine is getting the right amount of diesel.

The Exhaust

An improper exhaust system can be detrimental to the health of your diesel engine. When the exhaust system starts to malfunction, the gas might not be able to escape properly. This not only increases exhaust temperature but also slows everything down.
