Technical Principle
Micro-Scale Motion Mechanism
The Brownian motion of nanoparticles creates countless microscopic thermal bridges within the fluid. This continuous random movement not only enhances micro-scale mixing, but also establishes fast heat-transfer pathways at the nanoscale. By precisely controlling nanoparticle size and morphology, the micro-scale motion mechanism can be further optimized, resulting in a significant improvement in overall heat transfer efficiency.
Interfacial Enhancement Effect
Disruption of the thermal boundary layer is one of the core mechanisms behind the superior heat transfer performance of nanofluids. As nanoparticles move within the boundary layer, they continuously disturb the conventional flow and heat-transfer regime, effectively reducing thermal boundary layer thickness. This interfacial enhancement can lead to a substantial increase in the Nusselt number (Nu), in some cases reaching 3 to 5 times that of conventional fluids, thereby greatly improving convective heat transfer performance.
Enhanced Thermophysical Properties
The incorporation of nanoparticles significantly enhances the thermophysical properties of the base fluid. Improved thermal diffusivity accelerates the spread of heat throughout the fluid, while increased heat capacity strengthens its ability to absorb and store thermal energy. These improvements in fundamental material properties provide a solid basis for the overall enhancement of thermal transfer performance.
Product Performance, Technical Data, and Application Benefits
JINENG Nanofluid Coolant is a high-performance coolant developed to overcome the limitations of conventional glycol-based coolants under high-temperature operating conditions. By combining a high-boiling-point base fluid with highly thermally conductive nanoparticles, the product significantly enhances heat dissipation, improves combustion efficiency, and helps engines and thermal systems operate more stably across a wide range of demanding environments.
Key Physical Parameters
High Boiling Point
The product offers high-temperature protection up to 143°C under pressurized conditions. Its laboratory-tested boiling point under atmospheric pressure is 129°C, while the labeled boiling point is conservatively stated as 120°C. Compared with conventional coolants, which typically boil at 108°C to 110°C, the boiling point is improved by more than 20°C.
Low Freezing Point
The laboratory test report shows a freezing point below -50°C, while actual measured performance has reached -63°C. Compared with conventional coolants rated at around -30°C to -35°C, this represents a reduction of more than 30°C in freezing point.
Long Service Life and Low Corrosion
The recommended replacement interval exceeds 5 years or 250,000 km. By comparison, conventional inorganic coolants usually require replacement every 2 to 3 years, while typical organic coolants last around 3 to 5 years.
Ultra-Low Evaporation Loss
Laboratory testing indicates that the evaporation loss is approximately one-fifth that of conventional coolant, greatly reducing the risk of fluid loss during long-term use.

Performance Advantages
Fuel Saving and Power Improvement
Vehicle dynamometer testing showed an average fuel-saving rate of 5.3%. Real-world testing recorded fuel savings of 8.32%, and up to 10.77% in fully loaded highway conditions. Engine output improvement of about 6% was observed on an 80-horsepower engine. Users typically experience lighter throttle response, more noticeable acceleration, and reduced engine vibration and noise.
This improvement is based on a clear thermal management mechanism. Conventional coolants tend to perform poorly at high temperatures, making engines more likely to run hot. To suppress knock under these conditions, the engine control system may retard ignition timing, leading to incomplete combustion, higher fuel consumption, and reduced power. JINENG Nanofluid Coolant features a higher boiling point and highly conductive nanoparticles that strengthen heat dissipation, helping the engine maintain a more favorable combustion temperature. This allows fuel to burn more completely and supports more optimal ignition timing, improving both fuel economy and power output.
Reduced Emissions
Overall pollutant emissions were reduced by 32.5%, with CO reduced by 71.4% and HC reduced by 42.5%. This can also help reduce the frequency and cost of cleaning three-way catalytic converters and particulate filters.
The reason is directly related to improved combustion. When fuel burns more completely, pollutant formation is reduced accordingly.
Faster Warm-Up in Winter
Cold-start warm-up time can be shortened by 40% to 70%. This helps the vehicle reach operating temperature faster, reduces concerns during winter warm-up, lowers cold-wear on the engine and transmission, improves fuel economy, reduces carbon deposit formation, and delivers cabin heat more quickly.
This effect is linked to the lower specific heat behavior and enhanced thermal transfer characteristics of the nanofluid system. The inclusion of highly conductive nanoscale particles allows the coolant to respond more rapidly during the warm-up phase.
Improved Air-Conditioning Performance in Summer
In hot-weather use, air-conditioning outlet temperature can be reduced by 2°C to 3°C, improving cabin comfort while also reducing the starting energy demand of the A/C compressor.
This is because condenser performance is closely linked to radiator heat rejection. When the cooling system dissipates heat more effectively, condenser efficiency also improves. In addition, improved engine output helps support compressor performance, since the compressor is mechanically or indirectly load-linked to engine performance in many vehicle systems.
Lower Steam Pressure in the Cooling System
In practical use, the radiator hoses remain noticeably softer even when the engine is hot, and the risk of excessive internal vapor pressure is significantly reduced. This helps prevent coolant leakage, hose rupture, radiator seepage, and premature wear of cooling system components, while also reducing evaporation-related coolant loss.
The mechanism is tied to the product’s high boiling point and enhanced heat transfer capability. The nanoparticles help remove excess heat more efficiently through circulation and also reduce bubble formation, minimizing vapor film and flow blockage effects that typically reduce cooling efficiency in overheated systems.
Relief of Oil Burning and Carbon Deposit Formation
The product can effectively help relieve engine oil burning symptoms and reduce carbon deposit formation.
Under poor heat dissipation conditions, engines are more likely to overheat. High temperature may cause piston ring sticking, especially at the oil-control ring, reducing the ability to scrape oil from the cylinder wall. Valve stem seals may also swell or age more quickly, allowing engine oil to enter the combustion chamber. In addition, overheating often triggers ignition retard, leading to incomplete combustion and increased carbon buildup. Oil burning, cold starts, and low-speed urban driving can all worsen deposit formation. By improving heat dissipation and reducing overheating, JINENG Nanofluid Coolant helps reduce piston ring sticking, slow valve-seal deterioration, and support cleaner combustion, thereby helping relieve oil burning and reduce deposits.

Recommended Application Scenarios
Extremely Cold Regions
The very low freezing point fully supports anti-freeze requirements in severe winter environments. At the same time, users in cold regions experience a more obvious improvement in cold-start warm-up speed.
High-Temperature Regions
In hot climates, the higher boiling point and superior thermal conductivity of the nanofluid help improve heat dissipation, reduce combustion chamber thermal stress, and prevent overheating.
High-Altitude Regions
As altitude increases, boiling point decreases. Conventional coolants, already limited by relatively low boiling points, are more likely to boil over in high-altitude conditions. In addition, reduced oxygen concentration at high altitude can worsen incomplete combustion and limit engine output. JINENG Nanofluid Coolant offers a higher boiling point and enhanced heat transfer, helping maintain more stable thermal conditions, reducing boil-over risk, and supporting better engine performance.
High-Speed Driving

New Vehicles and Older Vehicles
For new vehicles, earlier use helps protect the engine and extend the service life of engine and cooling system components. For older vehicles experiencing performance decline, users often report a renewed driving feel, with noticeable improvements in power response and fuel economy.
Off-Road, Modified, Racing, and Drifting Applications
Under these extreme-use scenarios, conventional coolant often leads to overheating, power loss, and elevated oil and transmission temperatures. JINENG Nanofluid Coolant helps optimize ignition timing stability, reduce timing retard caused by excessive heat, and provide stronger heat dissipation under extreme conditions, helping maintain more stable water and oil temperatures during aggressive driving.

Market Background
Most coolants currently on the market are based on ethylene glycol mixed with water, with typical atmospheric-pressure boiling points around 108°C. In real operating conditions, engine coolant temperature does not remain fixed at 90°C but fluctuates within a range, with peak temperatures often reaching 110°C to 120°C. Under these conditions, conventional coolant may vaporize and create vapor blockage, preventing cylinder heat from being removed quickly enough. This can trigger ignition retard, incomplete combustion, higher fuel consumption, and reduced power.
There is also a U.S. brand of waterless polyol coolant with a very high boiling point and very long service life. However, in practical use it has shown poor heat dissipation performance, sometimes leading to overheating and shutdown, which limits real-world usability.
Some other brands promote organic coolant or so-called nanocoolant products with claimed pressurized boiling points of 131°C. In reality, their atmospheric-pressure boiling points remain around 108°C, meaning their core thermal performance is fundamentally similar to traditional products.
Based on these existing market limitations, the inventor of JINENG developed a new approach by introducing highly conductive nanoparticles to solve the key industry problem of high-temperature heat dissipation.
