In accordance with test methods specified in Chinese standards, our company has inspected MAZ products from various aspects.
Test mode: comparison between performance with MAZ added and that without.
Test method：engine bed test, entire car bed test, road test and endurance test;?
（1）Road test
（2）Engine test on bed
（3）Continuous entire car test on bed under different running conditions
（4）Test of entire car acceleration
（5）Strenuous test of 100-hour and 300- hour endurance of motor
（6）Motor dissembly test after traveling for 80,000 kilometers
（7）Fuel oil quality test and analysis
（8）MAZ toxicity test and water solubility test
（9）Engine detergency test on bed
Test content：economical efficiency, emission, detergency, power, endurance, reliability and some chemical and physical indicators of fuel oil.
Evaluation criterion: pursuant to relevant national standards

Fuel saving indicators:

Test organ:

Vehicle Emission Quality Supervision and Inspection Center of Beijing Institute of Technology

Oil Material Research Institute of the General Logistics Department of PLA

National Passenger Car Quality Supervision and Inspection Center （Tianjin）

National Automobile Quality Supervision and Inspection Center(Changchun)

Fuel saving rate

Gasoline car: 5.3% under various running conditions

10.2%, 11.01% and 9.25% respectively at constant velocity of 60km/h, 90km/h and 120km/h
Tanks and military vehicles: 3%- 7%. The longer distance, the more fuel saved.

Gasoline car：more than 3% (3.4%，5.7%）

Diesel motor：more than 2%

Pollutant emission drop rate indicators:?
Test organ:

Pollutant emission drop rate

National Passenger Car Quality Supervision and Inspection Center（Tianjin）

National Automobile Quality Supervision and Inspection Center (Changchun)

Gasoline car: the hydrocarbon, carbon monoxide and oxynitride in exhaust gas drop by more than 20%, 10% and 8% respectively;

Diesel car: carbon monoxide, oxynitride, PM and black smoke in exhaust gas drop by 11.11%, 4.66%, 29.94% and 66% respectively.

Detergency indicator:
Test organ: SINOPEC CORP Research Institute of Petroleum Processing (Beijing)

Test method: test on M111 engine bed according to gasoline detergency test method specified in GB/T19230.6

Test content: deposits at engine air intake valve and combustion chamber
Test result: the detergency of gasoline with Lanlian MAZ added meets national standard fully and even surpasses Euro III fuel oil standard.

Physical and chemical indicators:
Test organ: National Oil Product Quality Supervision and Inspection Center (Beijing)
Gansu Provincial Petroleum Products Quality Supervision and Inspection Station (Lanzhou)
Test content：: whether the quality of oil products is affected when Lanlian MAZ is added
Evaluation criterion: GB17930 "Motor Gasoline" and GB252 "Light Diesel Oil"
Test result: with Lanlian MAZ added, physical and chemical indicators of motor gasoline are not affected and conform to GB17930 standard; that of light diesel oil are also not affected and the cetane number rises by 2-4 and the GB252 standard is met.

Endurance indicator:
Test organ: National Automobile Quality Supervision and Inspection Center (Changchun)
National Passenger Car Quality Supervision and Inspection Center （Tianjin）
Oil Material Research Institute of the General Logistics Department of PLA (Beijing)

Test method：examination of opened parts of gasoline engines and diesel engines after running for 80,000 kilometers
Test content: engine endurance and reliability
Test result: the data about engines with MAZ added are better than those about engines without MAZ added, there is no erosion on spare surface and the deposit form and the worn parts values are normal. That is Lanlian MAZ would not cause any abnormal wear or damage of motors after long-term use.

Expert evaluation:
Domestic expert reviews were organized time after time, judging and evaluating the technical level and the fuel-saving and emission-reducing performance of Lanlian MAZ.
1. Academician Liu Guangding from Chinese Academy of Sciences organized a review attended by experts on petroleum, chemical engineering, automobile and environmental protection.
2. Academician Xue Qunji from the Chinese Academy of Engineering hosted an appraisal after Lanlian MAZ was declared as a scientific and technical achievement and innovative product.
3. Academician Guo Konghui from the Chinese Academy of Engineering hosted an appraisal about application effect of Lanlian MAZ.
4. Conclusion of appraisals and evaluations
