Power supply systems, release and decrease in toxicity of the fulfilled gases
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.
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 with 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.
You can receive the certificate of funds on HUNDRED.
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.
System of injection of the petrol engine
Electronic microprocessor system of the distributed injection (direct injection on the AWA engine) with a thermometric measuring instrument of weight of soaked-up air, an electronic accelerator. On the ALT engine - the inlet pipeline with changeable geometry
Engines 1.6, 2.0 of l (ALT) 14-17
System of injection of the turbodiesel engineElectronic, microprocessor, EDC15 + on engines of 1.9 l, with direct injection, rotor TNVD on engines of 2.5 l turbokompressory and cooling of blown air
Idling turns, in mines
Pressure of pressurization of a turbokompressor, atm, at rpm
The content in the fulfilled gases
Value a lambda 0.97 – 1.03
Efforts of a tightening of carving connections, Nanometer
The moments of a tightening of fixture are given also in the text of Head and on some иллюстрациях*.
*vydelenny in the text a bold print the moments of a tightening are subject to exact observance; the efforts not allocated with a bold print are given only roughly.
