It’s important to take care of problems with your vehicle right away. To make it easier for you to take care of your vehicle and to avoid problems, here are the answers to some of our most frequently asked questions. If you can’t find what you’re looking for, please contact us today.

What is the lifespan of a diesel engine?

Diesel engines, known for their robustness and endurance, often exceed expectations when it comes to their lifespan. A typical diesel engine can clock from 400,000 miles to an impressive 1,000,000 miles, significantly outlasting its gas counterparts that average around 200,000 miles. So what gives diesel engines this edge? The answer lies in their unique design and structure. Unlike petrol engines, diesel engines possess a more spacious interior that allows for greater oil circulation. Consequently, the engine components are able to function longer at optimal performance levels. Furthermore, the durability of diesel engines is credited to their overall design and the specific applications they are leveraged for, compared to other types of engines.

What are the most common diesel engine problems?

Diesel engines, despite their robust design and remarkable endurance, may sometimes encounter operational difficulties that can potentially affect their lifespan. The most reliable way to diagnose these problems is by reaching out to the original engine manufacturer for expert advice. However, here are some common issues diesel engines might face:

Black Smoke: This harkens back to the old locomotive engines and is a telltale sign of a serious diesel engine issue. Causes can range from a malfunctioning injector pump to a defective EGR valve, or even just low operating temperatures. Initial steps to address this should include cleaning the air system, but ultimately, consulting with a specialist is advisable.

Hard Starts: Diesel engines often struggle to start in colder conditions. However, weather is merely a trigger, pointing to underlying issues like faulty glow plugs, a failing battery, or problems within the fuel system.

Contaminated Fuel: Diesel fuel, owing to its higher viscosity, is particularly prone to contamination. Water, soot, and miscellaneous debris are the usual culprits. While refueling might solve the issue initially, an engine professional might need to intervene if the problem is not detected and addressed promptly.

Navigating these diesel engine complications can be challenging for the untrained eye. It is always advisable to seek professional help when a serious issue is detected. Reliable and industry-acclaimed professionals, like those at Cummins, are well-equipped to handle any diesel engine trouble you might encounter. Remember, engines can indeed be repaired, but accurate diagnosis and precise solutions are the domains of professionals.

How often should a diesel engine be serviced?

When considering the servicing needs of a diesel engine, it’s important to understand that various factors such as engine performance, type, and usage greatly influence the frequency of maintenance. While a general rule of thumb suggests servicing every six months, this is merely a guideline and not a one-size-fits-all solution. For instance, the Cummins’ service manual provides custom maintenance schedules based on the product type to accommodate this diversity in service needs.

Moreover, the context of use plays a pivotal role. A long-haul truck covering hundreds of miles daily will naturally have different servicing requirements compared to a personal diesel car that is driven less frequently. Similarly, the extreme demands placed on mining trucks – transporting heavy loads in harsh environments for prolonged periods – necessitate a unique servicing and maintenance schedule. Consequently, understanding the specific needs of your diesel engine based on its type and usage is paramount to ensuring its optimal performance and longevity.
