The automobile manufacturing industry has strict requirements for the viscosity characteristics of engine oil, the stability of fuel calorific value, and the control of sulfur content. Hengmei Electronic Technology provides professional solutions covering the full lifecycle performance evaluation of fuel and lubricants to meet the needs of the automotive industry, helping to improve engine efficiency and emission standards.
Fuel system efficiency improvement
Optimization of volatility and combustion characteristics:
Instrument: Hengmei Technology Fully Automatic Distillation Range Tester
Application: Accurately measure the distillation range of gasoline and diesel (initial boiling point, 10%/50%/90% distillation temperature, final boiling point, residual amount). Ensure that the fuel has appropriate volatility, which affects cold start performance, warm-up speed, combustion completeness, and tendency to form deposits.
Efficiency improvement: Optimizing the distillation range distribution can improve combustion efficiency, reduce incomplete combustion products (soot, HC), lower emissions, and reduce fuel injector carbon deposits.
Low temperature fluidity guarantee (diesel):
Instrument: Hengmei Technology pour point analyzer
Application: Accurately measure the pour point and pour point of diesel and evaluate its flow performance at low temperatures. This is crucial for starting vehicles in cold regions and ensuring the proper functioning of fuel filters.
Efficiency improvement: Ensure that diesel can flow smoothly at the expected operating temperature, prevent wax precipitation from blocking the filter and fuel supply pipeline, and ensure reliable engine start-up and operation.
Flash point safety control:
Instrument: Hengmei Technology Flash Point Tester
Application: Determine the flash point of fuel and evaluate its fire hazard during transportation, storage, and use. It is an important safety indicator.
Efficiency improvement: Ensure that fuel meets safety standards and reduce the risk of fire.
Accurate control of sulfur content (in compliance with environmental regulations):
Instrument: Hengmei Technology X-ray fluorescence sulfur analyzer (preferred, suitable for finished oil)/sulfur analyzer (coal quality - more suitable for coal or heavy raw materials, X-ray fluorescence is recommended for finished oil)
Application: Accurately and quickly determine the sulfur content in fuel. Ultra low sulfur diesel/gasoline is the key to meeting strict emission regulations such as National VI/Euro VI.
Efficiency improvement: Strictly controlling sulfur content is the core guarantee for protecting the efficient operation of post-treatment systems (such as DPF, SCR, GPF), reducing PM and NOx emissions, and meeting regulatory requirements.
Efficiency improvement of lubricating oil system
Quality control of base oil and additives:
Instruments: Hengmei Technology Acid Value Tester, Moisture Analyzer, Kinematic Viscosity Tester
Application:
Acid value: Detect the acid value of base oil and additives (especially detergent dispersants) to evaluate their degree of refinement and potential corrosiveness.
Moisture: Strictly detect the moisture content of the base oil and additive package (trace moisture has a huge impact on the performance of lubricating oil).
Kinematic viscosity: Accurately measuring the viscosity of base oil and finished oil is the basis for selecting and grading lubricants.
Efficiency improvement: Ensure that base oils and additives meet high standards, laying the foundation for producing high-performance lubricants.
Key performance guarantee of finished lubricating oil:
Instruments: Hengmei Technology sports viscosity tester, acid value tester, flash point tester, pour point tester, emulsion resistance tester
Application:
Kinematic viscosity: Accurately measure the viscosity of finished oil at 40 ° C and 100 ° C to ensure compliance with SAE grade requirements, directly affecting oil film thickness, friction, and energy consumption.
Acid value: Monitor the new oleic acid value, evaluate its oxidative stability starting point and potential corrosion tendency.
Flash point: Ensure the safety of lubricating oil in high-temperature working environments.
Condensation point/pour point: Evaluating the pumpability and flowability of lubricating oil at low temperatures is crucial for cold start protection.
Emulsification resistance: measures the ability of lubricating oil to quickly separate water after mixing with water. This is particularly important for crankcase oil (which may contain condensed water) and hydraulic oil.
Efficiency improvement: Fully guarantee the core physical and chemical performance standards of finished lubricating oil, meet the requirements of engine/component lubrication, cooling, sealing, cleaning, and rust prevention, extend engine life, and improve fuel economy.
Pollution Control - System Cleanliness Assurance:
Instruments: Hengmei Technology Oil Particle Counter, Karl Fischer Moisture Analyzer
Application:
Particle counter: (extremely critical!)
New oil/filled oil: Strictly detect the solid particle contamination level in the factory lubricating oil (according to ISO 4406/SAE AS4059 standards) to ensure extremely high cleanliness and protect the precision components of the engine (bearings, hydraulic control valves).
Production environment monitoring: Monitor the cleanliness of filling lines, storage tanks, etc.
Equipment cleanliness acceptance: Oil cleanliness testing before engine/transmission assembly and after flushing.
Moisture meter:
New oil/filled oil: Accurately detect trace amounts of moisture (ppm level), which is the main culprit causing oil oxidation, additive failure, sludge formation, corrosion, and cavitation.
Production process control: Monitor the storage, blending, and filling processes to prevent moisture intrusion.
Efficiency improvement: Effectively controlling particle and moisture pollution is the core measure to reduce abrasive wear, extend engine/transmission life, prevent oil degradation, and ensure hydraulic system response accuracy. The high precision of the Hengmei particle counter and the micro detection capability of the moisture analyzer are key.
Energy value determination (specific applications, such as testing the effect of fuel on lubricating oil dilution):
Instrument: Hengmei Technology Fully Automatic Calorimeter
Application: Mainly used to determine the calorific value (heat generation) of fuels (gasoline, diesel). When evaluating the impact of fuel dilution on the performance of lubricating oil, such as viscosity and flash point decrease, calorific value is an important parameter (which needs to be combined with other analyses).
Efficiency improvement: Assist in evaluating the degree of fuel dilution and its impact on lubricating oil efficiency.
Implementation and Value of the Plan
Establish a strict quality control process: at key nodes such as raw material storage, production process (blending, filling), and finished product delivery, use the above-mentioned Hengmei instruments to establish standardized testing items and qualification standards.
R&D support: Relying on high-precision instrument data as decision-making basis in the development of new oil formula, performance verification, and benchmarking with competitors.
Supplier management: Strictly inspect the products provided by suppliers of base oil, additives, and fuel components, and use data as an important indicator for evaluating and screening suppliers.
Production optimization: By real-time or rapid detection of data, adjust production process parameters in a timely manner to ensure stable product quality.
Cleanliness Engineering: Incorporate oil particle counting and moisture detection into the standard requirements for engine/transmission manufacturing, assembly, cleaning, and filling processes.
Data management: Integrate Hengmei instrument detection data into the LIMS system to achieve data traceability, analyzability, and warning.
