What is under the hood of a VAZ 2112 16 valves diagram

Engine model
The most powerful engine of all that was installed on the “ten” is the injection 16-valve VAZ-2112 with a volume of 1.5 liters. However, this power unit has one drawback: if the timing belt breaks, the pistons meet the valves, which leads to serious and expensive repairs of the power unit. And high-quality repair and maintenance of VAZ-2110 injection engines requires special diagnostic equipment. Often, a malfunction of just one sensor leads to unstable operation of the entire engine.

1.3. Overall dimensions of the VAZ-2112 car

Small class cars VAZ-2110 (export name Lada 110) with a four-door five-seater sedan body (class C according to the international classification) are equipped with engines of 1.5 and 1.6 liters, with a power of 58–68 kW (79–92.5 hp). c.), located across the engine compartment.

Previously, cars at the factory were equipped with 1.5 liter engines: first with carburetor engines, and then with a distributed fuel injection system. Currently, cars are equipped only with engines with a displacement of 1.6 liters: eight-valve VAZ-21114 and sixteen-valve VAZ-21124 with distributed fuel injection systems and three-component exhaust gas catalysts with feedback. The engines meet Euro-2 and Euro-3 standards.

The body is load-bearing, all-metal, of welded construction with hinged doors, front fenders, hood and trunk lid. The VAZ-2110 car is the first sedan in Russia with a hatch that can be opened from the trunk leading into the cabin, which allows you to transport long items.

Part of the production modification 21103 with a 16-valve VAZ-2112 engine is equipped with air conditioning, and since the end of 2002, on request, power steering from ZF.

This modification differs from the basic one by a hood with an integrated radiator lining of a more modern shape and a front bumper, as well as original headlights. The rear lights, moldings and interior details have also been changed.

In 1998, production of the VAZ-2111 car (export name Lada 111) with a station wagon body began. According to the layout, engine, transmission, chassis, body equipment, this car is identical to the VAZ-2110 car. It features a redesigned rear end with a large tailgate. The trunk of this car is the most spacious in the family: 490 liters with the rear row of seats raised and 1420 liters with them folded.

Production of the VAZ-2112 car (export name Lada 112) with a hatchback body began in 2000. The layout of this car is the same as that of the VAZ-2111, but the body has a large rear angle. The engines are used only with a distributed injection system, both 8-valve and 16-valve. The rear seat folds in a 2:3 ratio, which increases trunk capacity from 415 to 1270 liters. The interior, like other models of the family, is equipped in “standard”, “norm” and “luxury” trim levels. The latest equipment includes fog lights, headlight cleaner and washer, 14-inch alloy wheels, three-way catalytic converter (Euro 2), internal bonnet lining, door security bars, immobilizer, on-board monitoring system, velvet seat upholstery and soft upholstery doors, central electric door locking, electric windows. By additional order, an on-board computer, electric front seat heaters, electric outside rear-view mirrors, anti-lock brakes, an airbag and a sunroof are installed.

Tuning the engine compartment. Engine lighting

In continuation of the materials on tuning, we would like to present an unusual option for decorating the engine compartment of your car.
The source of illumination for the engine elements in this case is LEDs and LED strips. And so let’s imagine, it’s getting dark outside, you approach the car and open the hood, the hot-looking engine shocks the people around you. This effect is created using red LED sources. Beautiful. And at the same time it looks impressive.

In the example presented, the LEDs were installed under the motor protective casing.

The result of such tuning will look impressive on cars that have a protective casing. In the presented example you can see how this was done on a VAZ 2110 engine.

For illumination, an LED strip was used, the length of which is 85 cm. It was also secured to iron corners in the radiator area

When connecting the LED backlight, you should pay attention that all the wiring that you used must be insulated and corrugated. The power source must be connected through a fuse (for convenience, use a plug-in fuse) Also make sure that all wiring is at a certain distance from very hot engine elements

VAZ-2112 diagram

The VAZ-2112 car was produced at AvtoVAZ from 1998 to 2009, in Ukraine from 2009 to 2014. The following are color wiring diagrams (injector and carburetor) with a description of all elements for various modifications. The information is intended for self-repair of cars. Electrical circuits are divided into several blocks for ease of viewing via a computer or smartphone; there are also circuits in the form of a single picture with a description of the elements - for printing on a printer in one sheet.

To diagnose and repair yourself, first look to see if everything is okay with the generator. Is it put on well and does not sag? This procedure must be done with all versions of the fuel system, both carburetor and injection. We check the fuses according to the electrical diagram. The reverse side of the safety block cover will also be of great help. There are clues there that the diagram will help you decipher. Replace the burnt out element and try to start the car again. You need to check whether the battery terminals are tightly connected and whether they are oxidized. Is the wire going from the battery to the generator and to the starter damaged?

Installation of fog lights

Car owners can independently equip their car with fog lights. To make installation easier, you can watch videos from forums where craftsmen share their experience of such work.

Conclusions: in fact, replacing old wiring in the rear of a car is much easier than in the engine compartment or inside the cabin. And the diagrams proposed in the article will help you figure it out faster and avoid mistakes.
