VAZ-21112 engine: description, specifications

Over the entire production period, AvtoVAZ has produced a sufficient number of vehicles and power units. One of these was the wagon VAZ-21112. This is a modernized version of the classic 2111 vehicle with 1.6 engine.

Specifications and Description

Unlike its counterparts, the VAZ-21112 engine received a volume of 1.6 liters and an 8-valve block head. In fact, this is the same engine of the 083rd series, which was modified by the designers. The cylinder block became 2.3 mm higher, which made it possible to increase the piston stroke to 75.6 mm. Thanks to the improvement of the unit, the designers managed to achieve a volume of 1.6 liters. Environmental standards have also been raised.

The timing remained with a belt drive, which does not exclude bent valves during a break . It is recommended to replace the belt mechanism every 40 thousand kilometers. The absence of hydraulic lifters is also very frustrating for the owners, which forces motorists to regulate valves every 40 thousand km. The rest is the standard ICE 2111.

Service

Maintenance of the VAZ-21112 motor is typical for the entire 2111 series. The service interval for changing the oil and filter is 15,000 km. But, as practice shows, in order to increase the motor resource to 250,000 km, it is better to carry out maintenance every 10,000 km.

At every maintenance, a 3.5 liter engine oil changes as well as an oil filter. The original catalog number is 21081012005. You can also choose analogues of the original product from this article.

Major malfunctions

The VAZ-21112 motor has a number of shortcomings that cause regular malfunctions. This is the problem of all power units manufactured by AvtoVAZ. So, let's consider what problems await the owner of this motor:

Cylinder head repair 21112
  • Swim speed. In this case, the fault will be the idle speed control or the throttle wedge. It is also recommended that you check the mass air flow sensor.
  • Friction. Here the reason can be sought for a long time, so it is recommended to conduct computer diagnostics first, and then look for the problem in mechanics.
  • Frequent overheating. This is not the fault of the designers, but the reason for the quality of spare parts. So, overheating is caused by a jammed thermostat. Replacing an item should solve the problem. It is also worth paying attention to the level of coolant in the system.
  • Metal ringing and knocking. The lack of hydraulic lifters makes itself felt. That means it's time to adjust the valves.
  • Leaking engine oil. This is due to the breakdown of the gaskets. This is especially true for the valve cover gasket and block head. Replacing items should help solve the problem.

As you can see, the malfunctions are not critical, but give the owners of the VAZ-21112 a lot of trouble, especially if they are regular.

Tuning

The most high-quality and reliable way to modify the VAZ-21112 engine is to change the eight-valve head to 16V. But this method is expensive, so motorists choose the simplest option. We change the standard camshaft to the production of "Nuzhdin" 10.93, mount the split gear. Next, install the receiver and the damper with a diameter of 54 mm. Some motorists recommend lowering the head height and replacing the valves. All this will make it possible to develop up to 115 hp.

Motor tuning

The second option, to get additional motor power, is to install a compressor. To do this, set the camshaft "Nuzhdin" 10.63. There are enough options for suitable compressors, it is best to consult with sellers.
