Introducing the New PatFluid® CV from CDTi

""
  • CDTi -

For operators of diesel-powered vehicles and equipment, Diesel Particulate Filters (DPFs) have become both a solution and a source of frustration. These filters are essential for reducing harmful diesel emissions—but when they clog, they can cause downtime, expensive repairs, and real headaches.

That’s where PatFluid® CV, the latest innovation from CDTi, comes in. Specifically developed for commercial diesel engines and available in markets outside the Americas, this powerful additive tackles the two most common issues facing diesel users: DPF blockages and fuel injector deposits.

Let’s take a closer look at what PatFluid® CV is, how it works, and why it’s the diesel problem-solver you’ve been waiting for.

The Rise of Diesel Particulate Filters

Over the last 25 years, Diesel Particulate Filters (DPFs) have become standard equipment on new diesel vehicles, from delivery vans to generators. They capture particulate matter produced during diesel combustion, helping reduce air pollution and meet regulatory standards.
CDTi has developed DPF products, including:
  • CombiFilter® : An active DPF system verified for off-road use in mining, construction, and material handling. It offers both on-board and off-board regeneration options to suit different fleet sizes and shift schedules.
  • CatTrap® : A passive DPF with over 25 years of proven performance in mining and off-road applications. It features a durable catalyst design that reduces over 95% of particulates without promoting NO2 emmissions.
While DPFs are effective, they come with a catch—they need to regularly reach high enough temperatures to burn off the trapped soot—a process called regeneration. Unfortunately, many diesel applications, like stop-start urban driving or long periods of idling, don’t allow those high temperatures to build up consistently. This leads to soot accumulation, higher backpressure, and blocked filters, which can cause power loss, increased emissions, and even complete DPF failure.

PatFluid® CV: The Diesel Problem-Solver

PatFluid® CV is a multifunctional diesel fuel additive that helps diesel engines and vehicles operate more efficiently by addressing two key pain points:

  • Improving DPF regeneration to reduce blockages and damage.
  • Cleaning and protecting injectors to maintain optimal fuel delivery and engine performance.
This isn’t just a maintenance aid—it’s a proactive solution designed to reduce downtime, lower operating costs, and extend the life of emission control systems.

How PatFluid® CV Works

PatFluid® CV reduces DPF blockages, lowers the risk of damage, and helps your engine operate closer to its original factory performance. Here’s how it works:
  • Improved DPF Regeneration: The DPF additive component of PatFluid® CV survives combustion and reaches the filter along with the soot. It acts as a fuel-borne catalyst, lowering the temperature needed for soot to burn off. That means your DPF can regenerate at temperatures more commonly seen during regular vehicle operation—not just under high loads or long drives.
  • Enhanced Injector Cleanliness: The deposit control additive removes existing deposits from fuel injectors and prevents new ones from forming. Clean injectors restore proper fuel spray patterns, leading to better combustion, lower emissions, and improved fuel economy.
By using PatFluid® CV regularly, diesel operators can expect:
  • Fewer DPF blockages and regeneration events
  • Lower maintenance costs from reduced filter cleanings and replacements
  • Less downtime due to fewer emission-related issues
  • Improved fuel economy through cleaner injectors and more efficient combustion
  • Extended engine and DPF system life
It’s a simple, cost-effective way to get more out of your diesel-powered equipment—especially for fleets that run in conditions where regeneration is a challenge.

Importance of Deposit Control Additive

Dirty or partially clogged fuel injectors affect everything from fuel efficiency to emissions output. Even small amounts of deposit buildup can reduce spray precision, leading to incomplete combustion and excess soot production—which, in turn, fills your DPF even faster.
The deposit control technology in PatFluid® CV:
  • Removes stubborn injector deposits
  • Keeps new deposits from forming
  • Restores lost fuel economy and power
  • Reduces particulate emissions and DPF filling rate
With cleaner combustion comes cleaner emissions—and a DPF that doesn’t have to work as hard.

Testing and Validation

To ensure high performance, PatFluid® CV has undergone rigorous testing:
  • Thermogravimetric Analysis (TGA): Lab-based soot oxidation testing that measures the impact of the additive on soot oxidation temperature—a key indicator of regeneration efficiency.
  • Engine Dyno Testing: Controlled engine testing that simulates real-world conditions, verifying the additive’s performance in reducing deposits, enhancing and maintaining power output.
These testing methods confirm that PatFluid® CV performs reliably and consistently, offering diesel operators peace of mind.

Continuation of Innovation: PatFluid® CV Development from CDTi

PatFluid® CV builds on the trusted performance of the original PatFluid® product line, and is developed on the back of three decades of experience, delivering enhanced protection and performance for today’s diesel engines.

PatFluid® CV represents the next generation of diesel fuel additive technology from CDTi—optimized for emission control, fuel economy, and long-term reliability.

Cleaner Diesel, Smarter Solutions

For commercial diesel operators, emissions compliance and engine reliability are non-negotiable. CDTi’s PatFluid® CV is designed to meet these demands head-on, offering an all-in-one solution to DPF blockages and injector deposits—two of the most common and costly problems facing diesel fleets today.

If you’re experiencing DPF-related issues, frequent maintenance, or performance drops in your diesel vehicles, PatFluid® CV could be the solution you’ve been waiting for.
