Power supply system and release

Separate characteristics are provided also in the text of Head and in case of obligation of their performance are allocated with a bold print

Petrol models
Unleaded gasoline is not worse AI-95/A-85, probably temporary application of unleaded gasoline is not worse AI-91/A-82.5. Thus engine capacity will decrease a little, at increase in fuel consumption
Do not apply an additive to fuel. They can result in the increased wear or engine damage. 
Diesel models
Summer and winter diesel fuel No. 2 or No. 1 on ASTM D975
Do not apply ship (Marine Diesel Fuel), boiler, etc. diesel fuel.
When using diesel fuel about the content of sulfur over 0.5 %, make replacement of impellent oil each 7500 km.
Winter fuel, provides normal working capacity to - 20°С.
Thanks to preliminary heating of fuel at the included system of heating of the car, the car on winter diesel fuel can be maintained, as a rule, without refusals at temperature of external air to - 25°С.
Do not add gasoline to diesel fuel.
In case of application of summer diesel fuel, and also at temperature of external air is lower - 15°С to fuel it is necessary to add certain, depending on temperature of external air quantity of means for fluidity or kerosene improvement.
Means for improvement of fluidity can be used also in a combination to kerosene.
For fluidity improvement you can receive the certificate of the allowed funds on any HUNDRED Mercedes-Benzs.
The additive share taking into account temperature of external air should be minimum.
The share of kerosene in a mix should make no more than 50 %.
Additive add to diesel fuel before loss of property of fluidity of diesel fuel owing to paraffin allocation. Owing to allocation of paraffin it is possible to eliminate malfunctions only with heating of all power supply system.
Mixing of diesel fuel with kerosene carry out only in a fuel tank. For this purpose in a tank at first fill in kerosene, and then add diesel fuel.
After that the engine should work some time in order that the mix was distributed on all power supply system.

Additives of kerosene lead to decrease in a point of ignition of diesel fuel. Thereof danger at the address with a fuel mix increases. Observe the corresponding safety regulations!

System of injection of the petrol engine: electronic microprocessor system of the distributed injection of ME SFI 2.0 or HMS. The inlet pipeline with changeable geometry
System of injection of the diesel engine: electronic microprocessor «Common-Rail» with direct injection, a turbo-supercharging and cooling of blown air
Pressure of fuel, atm.
The engine 113, with the connected vacuum
Productivity of the fuel pump
