With the development of science and technology and the enhancement of environmental awareness, diesel engines are increasingly used in various mechanical equipment, and CJ-4 diesel engine oil additive package has become an indispensable maintenance product.
CJ-4 diesel engine oil additive package is a maintenance product specially designed for diesel engines. Its main ingredients include fuel additives, engine protection agents, lubricants, etc. The main function of this product is to improve fuel efficiency, reduce wear, and protect the engine. It can also reduce emissions and meet environmental protection requirements.
The API CJ-4 classification represents a significant milestone in the development of diesel engine oil technology, designed specifically for high-speed, four-stroke engines to meet 2007 exhaust emission standards in the United States. Introduced in 2006, CJ-4 oils are compatible with diesel engines fitted with after-treatment systems, such as Diesel Particulate Filters (DPFs) and Exhaust Gas Recirculation (EGR) systems. They are formulated to provide enhanced protection against the higher levels of soot and acid accumulation associated with EGR-equipped engines and to ensure compatibility with after-treatment systems. Here’s how the CJ-4 diesel engine oil additive package serves as a secret weapon to improve fuel efficiency and protect your engine:
Improved Soot Handling
CJ-4 oils are engineered with advanced dispersant technology to manage higher soot levels. Effective soot dispersion prevents the agglomeration of soot particles, which can lead to wear and tear on engine surfaces, ensuring the engine runs smoothly and efficiently.
Enhanced Wear Protection
The additive package includes robust anti-wear agents that form a protective layer on engine components. This layer significantly reduces metal-to-metal contact, especially in critical high-stress areas, thereby extending the engine’s service life.
Superior Oxidation Stability
CJ-4 oils contain antioxidants that prevent the oil from breaking down under high temperatures, which is particularly important in modern diesel engines that operate at higher temperatures due to tighter emission controls. This stability helps maintain oil viscosity and prevent the formation of harmful deposits.
Corrosion and Acid Neutralization
Acid neutralizers in the CJ-4 formulation combat the corrosive effects of acids formed during fuel combustion. By neutralizing these acids, the oil protects critical engine parts from corrosion, further enhancing engine life.
Reduced Ash Content
Low-ash formulations in CJ-4 oils are specifically designed to ensure compatibility with after-treatment devices like DPFs. By reducing ash content, these oils help prevent the clogging of particulate filters, thereby maintaining engine performance and efficiency.
Improved Fuel Efficiency
The friction modifiers and viscosity improvers in CJ-4 oils contribute to reduced internal engine friction, allowing the engine to operate more efficiently. This reduction in friction not only helps improve fuel efficiency but also contributes to lower emissions.
Protecting After-Treatment Systems
CJ-4 oils are formulated to be compatible with after-treatment systems. They minimize the buildup of deposits within these systems, ensuring they operate effectively to reduce emissions without compromising engine performance.
Understanding CJ-4 Additive Packages:
CJ-4 Classification: This API rating signifies the oil meets standards for modern high-performance, low-emission diesel engines. CJ-4 oils contain robust additive packages for wear protection, oxidation resistance, soot control, and emission control system compatibility.
Additive Packages: These concentrated blends can further enhance specific properties of the base oil used in CJ-4 oils. However, a high-quality CJ-4 oil already has a well-formulated additive package.. If you have concerns about your specific engine’s needs, consult a qualified mechanic for professional advice.
