"Three years ago when I purchased this Omar, I had a friend who recommended me to use Cummins's antirust pouch . After using it, I found out that this product was indeed effective. The most obvious is that compared to the previous car. The situation of rust basically disappeared." Cummins ISF engine summer care activities on site A user of antifreeze additive rust prevention treasure DCA4 produced by Cummins Filtration told China Truck Network reporter.
However, the reporter learned at the event site that more truck users in the Guangdong region have maintained their cooling system maintenance habits by adding water directly to the tank instead of coolant (antifreeze) products containing the core additives. Such maintenance habits pose a high risk to the cooling system. "Later, the cylinder liner inside the engine was worn. I only knew that adding water to the water tank did not add any additives. I really couldn't do it." A Guangzhou user at the scene told reporters that the truck's cooling system had caused the engine to rust. The tragic experience of major repairs is not uncommon.
Cooling System "Three Killers": Corrosion Cavitation Scale
The engine cooling system is very important to ensure the normal operation of the engine, and the important role of the cooling fluid (known as antifreeze on the market) is not only reflected in the anti-freeze and anti-boiling, but also reflected in the waterproof scale, rust prevention and anti-cavitation erosion. The temperature in the Guangdong region is relatively higher than that in the cities of northern China. Even if the driver does not apply the coolant (antifreeze), there will be almost no cold start problems. It is not uncommon for water to be filled directly into water tanks during maintenance. However, if the cooling system is completely protected from any effective chemical components after a period of maintenance, the above-mentioned rust, and even the rusting of the core components of the engine, and the cavities will begin to appear. As a result, the cost of overhauling engine components is much greater than the chemical products needed to properly use the cooling system.
Corrosion, cavitation and scale are the three "killers" of the engine cooling system. Let's talk about corrosion, which can be simply summarized as metal oxidative rust in the engine cooling system. This oxidation reaction can occur on almost all metal components in the engine cooling system. Cylinder liners, water pumps, thermostats, radiators, and metal pipes can all be rusted and even rusted. Furthermore, cavitation erosion, violent movement of the piston in the engine cylinder caused violent vibration in the cylinder liner; this vibration caused bubbles in the cylinder wall. When the vibrations continue to occur, these bubbles will explode and rupture in an instant due to extreme pressure. This momentary explosion damages the interior of the engine cylinder. The last is scale, like the common scale in the kettle, and the scale system is also susceptible to scale deposits. When the scale adheres to the liner, an insulator is formed. It will make the heat of the cylinder wall unable to conduct into the cooling medium. As time goes by, the engine cooling effect will be affected and the oil consumption will increase; if it is serious, the piston ring may be damaged and the entire engine will fail.
The rational use of additives is a good way to deal with the "three killers" of the engine cooling system.
Cummins Filtration "Rustproof Pod" Core Protection Effectiveness
"Anti-rust treasure" DCA4 is the core additive of the cooling system produced by Cummins Filtration. As an internationally recognized high-quality product, DCA4's ability to prevent rust, prevent cavitation, and scale is outstanding. Currently, DCA4 has been officially put into production in Shanghai and is market-oriented. In simple terms, "rustproof" DCA4 protects the cooling system components from rust and cavitation by forming a protective film on the cylinder wall of the cylinder liner; on the other hand, it encapsulates the scale particles by only polymerizing components, making them unable to adhere In the cooling system components, to ensure good thermal conductivity, to maximize the protection of the normal operation of the engine cooling system.
"Anti-rust Po" DCA4 can reduce the total cost of operations and avoid neglecting maintenance of the cooling system. It can be used with a variety of brands of coolant products on the market is a highlight of its product characteristics. The use of DCA4 additives can greatly reduce the life-cycle cost of the engine. For a one-year use cycle, the total cost of properly using DCA4 to maintain the engine cooling system for conventional tanks is much lower than using only water and using coolant without effective core additives. Due to minimizing the replacement and overhaul costs caused by scale, cylinder cavitation, metal corrosion, etc., “Antirust Pod†DCA4 can save engine users up to several thousand yuan in maintenance costs within one year.
