Diesel Injectors and Their Impact on Diesel Trucks


Supertech Diesel Truck Specialists | Nanaimo

The diesel vehicle market is witnessing an unprecedented growth, particularly in secondary and developing countries, where the demand for reliable light-duty and heavy-duty trucks is on the rise. This trend is reflected in the surge of diesel vehicle registrations, a pattern that’s expected to continue robustly in the coming years.

At Supertech Diesel Truck Specialists in Nanaimo, we’re at the forefront of this evolution, offering a range of top-tier diesel injectors designed for various truck models, enhancing both performance and efficiency.

Fuel Injector

The Achilles’ Heel: Water Contamination

Water in fuel is the main adversary of fuel injectors. It displaces essential lubrication, accelerating wear and leading to premature failure. Hence, maintaining pure fuel is not just a recommendation; it’s a necessity for the health of your engine.

The Relentless Duty Cycle

Consider this: typical diesel engines in North America rev at about 1800 RPM, translating to approximately 140,000 injector cycles per hour. This relentless repetition demands resilience from injectors, which also face threats from carbon build-up and particulate matter due to inadequate air filtration, as well as the quality of fuel and additives used.

Controlled Precision

The Engine Control Module (ECM) is the conductor, orchestrating the fuel injectors’ symphony. It ensures injectors receive constant power with the key on, grounding them to allow for the precise fuel dispensation demanded by the engine’s power needs. This process, completed in mere milliseconds, is pivotal for engine efficiency.

Injector Types: Throttle Body vs. Port Type

We have two primary types of diesel fuel injectors: throttle body injection and port type injection. Throttle body injection centralizes fuel delivery, leading to potential mixture inconsistencies across cylinders. Port type injectors, a more modern and efficient system, eradicate this imbalance by metering individual fuel amounts directly to each cylinder.

The Anatomy of an Injector

Delving into an injector’s anatomy, we find an assembly of 15 essential parts, from the filter to the spray tip. Each part plays a role in the accurate regulation of fuel flow, directed by the ECM, and ensures an even spray pattern crucial for engine performance.

Understanding Injector Failures

Despite their robustness, common rail systems aren’t immune to breakdowns. The primary culprit for premature failure is fuel contamination, where even micron-sized debris can act like sandpaper on delicate sealing surfaces. The presence of water in fuel, leading to corrosion and component wear, ranks as the second most common issue. Incorrect installations, including improper tightening and inadequate cleaning, are also factors that can compromise injector performance.

Choosing the Right Injector

Diagnosing fuel injector problems necessitates the right tools and expertise. Misdiagnosis not only adds to repair costs but also to customer frustration.

When it comes to replacement, remanufactured injectors are often the go-to solution. However, the quality varies significantly. OEMs typically replace more components during the rebuild process, using assembly line parts, which translates to higher quality products. These injectors are also flow-tested to ensure they meet original specifications.
