Power supply systems, release and decrease in toxicity of the fulfilled gases Specifications
Fuel
Petrol models Neetilirovannyj gasoline is not worse PETROL-95/А-85, probably time application unleaded is not worse some gasoline PETROL-91/А-82.5. Thus capacity of the engine will decrease a little, at increase in the expense of fuel Do not apply an additive to fuel. They can lead to the raised deterioration or engine damage. Diesel models Summer and winter diesel fuel № 2 or № 1 on ASTM D975 Do not apply ship (Marine Diesel Fuel), boiler, etc. diesel fuel. At use of diesel fuel with the maintenance of sulphur over 0.5 %, make replacement of impellent oil each 7500 km. Winter fuel, provides normal working capacity to-20°S. 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°S. Do not add gasoline to diesel fuel. In case of application of summer diesel fuel, and also at temperature of external air more low-15°S to fuel it is necessary to add defined, depending on temperature of external air quantity of means for fluidity or kerosene improvement. Means for fluidity improvement can be used also in a combination to kerosene. You can receive the inquiry on means on HUNDRED. The share of an additive with the account of temperature of external air should be minimum. The kerosene share 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. Malfunctions owing to paraffin allocation can be eliminated only heating of all power supply system. Mixing of diesel fuel with kerosene spend 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 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 engine AWA) with a thermometric measuring instrument of weight of soaked up air, an electronic accelerator. On engine ALT - the inlet pipeline with changeable geometry Engines 1.6, 2.0 l (ALT) 14 - 17
System of injection of the turbodiesel engine Electronic, microprocessor, EDC15 + on engines of 1.9 l, with direct injection, роторным ТНВД on engines of 2.5 l турбокомпрессором and cooling of blown airCandles накаливания
Idling turns, in mines
Pressure of pressurisation турбокомпрессора, атм, at rpm
The maintenance in the fulfilled gases
Value лямбда 0.97 – 1.03
Efforts of a tightening of carving connections, Nanometer The moments of a tightening of fixture are resulted also in the text of the Head and on some иллюстрациях*. *Выделенные in the text a bold type the tightening moments are subject to exact observance; the efforts not allocated with a bold type are resulted only roughly.
