THE GENERAL DATA

Air pipe of new type of engine ONS equipped with injection of fuel

And – an elastic tube,

In – an aperture of fastening,

With – a fastening collar

KRIVOSHIPNO-SHATUNNYJ THE MECHANISM

Pistons

Since February, 1987 (a code 7В02) in engines ONS 1,6 дм3 and since September, 1986 (a code 6J15) in engines ONS 2,0 дм3 displacement of an axis of a piston finger concerning an axis of the piston about 0,8 mm to 0,6 mm is reduced. New pistons cannot be established with old rods and on the contrary.

Fuel system

Since May 1987 codes (a code of date of manufacturing "HL") are changed some adjusting data of the two-chamber carburettors Weber intended for engines ONS 2,0 дм3 – the deviation air заслонки at the beginning of work of a vacuum regulator in all carburettors Weber 85 HF makes 8 mm.

Since January, 1988 (the code of date of manufacturing "JB") in engines with gasoline injection is established an air pipe of new type.

Since May, 1988 cars with engine ONS 1,8 дм3 are equipped with new carburettor Pierburg with a designation 85 HF 9510 КС. Its distinctive sign is the yellow point on the valve of the enriching device.

Since July, 1988 (the code of date of manufacturing "JG") in engines ONS 1,6 дм3 is used the new carburettor of type 84 HF 9510 DB with the electromagnetic valve blocking giving of fuel after deenergizing of ignition for prevention of spontaneous ignition.

Adjusting data of the carburettor 84 HF 9510 DB

Number of turns of idling: 875 20 rpm.
The maintenance WITH: 1 %.

Other adjusting data same, as well as in two-chamber carburettor Weber 84 HF 9510 CA.

Other information, concerning a technical characteristics, adjustment and repair of engines ONS, is in subsection 4.1 and subsection 3.1.3.1.
