The internal combustion engine test at laboratory of Polytechnic University, one of the leaders of educational and research activities in Russia, conducted independent studies of the amended RESURS Next.
The tests results on engines with mileage were interesting and varied.
At this stage of the engine life,
negative signs of wear are already expressive:
unbalanced compression on the cylinders, power drop, extraneous noise and vibration, oil burn and fuel consumption.
In addition to external wear,
internal changes are also observed that require intervention:
microcracks and scoring on the metal surface of parts, high-temperature and low-temperature
Therefore, the authors of the study analyzed the widest possible range of additive options:
Restoration degree of damaged (worn) engine parts
The dynamics of changes in the effect of our additive for a long time;
The RESURS Next after effect duration
Step zero: Measuring engine performance before RESURS Next processing. Set checkpoints to control all changes in the roughness parameter.
Step one: Introduction one 75g bottle of additive in oil.
Step two: Introduction another one 75g bottle of RESURS Next.
Step three: Evaluation of after effect. Pure oil without RESURS Next. After each stage, the test authors measured the dynamic characteristics of the engine and the roughness at the control points.
In the second test cycle, the authors intend to exceed the dosage recommended by the manufacturer in two times to study the effect of RESURS Next concentration on the efficiency of the engine.
The average roughness values are given in the table. For a full description of the stage, see p. 71 of the report
The result inspired us!
The roughness parameter in some control points decreased by 66%, that means that the surface leveled more than half. The recovery process goes better for parts with "soft" working surfaces bearing shells of the crankshaft. For parts with "hard" working surfaces: chrome surfaces of piston rings and the working surface of the cylinders, roughness is reduced by 28% and 48%, respectively.

Surface restoration occurs by forming a new metal layer. Metal plating particles of RESURS Next embedded in the structure of the damaged surface, filling the microcracks and microdamages. The restoration of cylinders, pistons and liners leads to a comprehensive improvement in the dynamics of the engine work.
Also from the analysis of the obtained data follows the tendency of increasing compression in engine cylinders, progressing due to increasing of concentration of Resurs.
After the ﬁrst treatment, the growth of compression was registered on average by 6%, after the second - by 4%. Thus, after two treatments the growth of compression was 10%. At the moment of evaluation of the aftereffect the tendency of the compression decrease begins to appear only at the ﬁnal stage of the tests.
RESURS Next restores worn surfaces up to 66%, which contributes to a complex improvement in the dynamics of the engine:
1. Alignment of compression on the cylinders
2. Improvement of lubrication conditions
3. Restoration of oil pressure in the lubrication system
4. Reduction of the power of mechanical losses by 8-10%
5. Reduction of fuel consumption by 5-7% compared to the result obtained with an engine with a low degree of wear
6. Reduction of toxicity of exhaust gases
