Alteration of carburetor on the injector in the car VAZ-2109

Causes to redo the carburetor on the injector in its VAZ-2109 are different. To someone else - to increase the possibilities of the car. Is it worth it in general, do? If the answer is positive, then the article is for you. We will tell how to remake the carburetor on the injector VAZ-2109.

Does it make sense in the alteration?

The carburetor engine has long been "morally outdated." In the second half of the 90s of the last century, VAZ cars transferred to the injector package. Nevertheless, carburetor engines remain the mass of "fans", claiming that the carburetor is not so bad. Before proceeding with the re-equipment of the car, we'll figure it out in detail, is it all definitely? Maybe the carburetor is still early sent to the dump of history? Rephrase Hamlet and ask yourself: "What is the question?" This, of course, joke. But really, is it worth investing so much effort?

• For the re-equipment of VAZ-2109, it will be necessary to invest at least $ 500. It is unlikely that savings from the use of an injection engine will pay for such expenses. Maybe only in the long run.
• Environmental indicators of the machine can be corrected much easier. Install the vortex aerodynamic device. Buy such an aggregate is easy, it is inexpensive, it is installed quickly.

Why change the carburetor?

Let's start with the fact that no one installs the carburetor engines in the entire civilized world for a long time. In the countries of the European Union, entry on such cars is prohibited from considerations of environmental safety. There are some more significant arguments:

• a significant drop in the engine power at high revs;
• there are problems with overtakers. Bypassing cars on the track by car with a carburetor engine - this is generally a full nightmare (especially taking into account the modest possibilities of VAZ-2109);
• substantial fuel consumption compared to the injector;
• "Small" inconvenience, for example, manual air damper control, etc.

Of course, you can treat philosophically and find positive parties even where they are not. For example, with the same manual damper control. Some drivers argue that in winter conditions such a "function" is a plus, allows you to "feel" the engine. But only an incorrigible optimist can agree with this statement.

Advantages of the injector

Having considered the disadvantages of the carburetor, it is impossible not to bypass the positive aspects of the injector engine. Among explicit advantages, the following can be distinguished:

• fully complies with the requirements of environmental legislation on emissions into the atmosphere;
• (especially in high revs);
• the maintenance of the injector is much cheaper;
• fuel consumption decreases (up to 6 liters per 100 km);
• there is the possibility of installing gas equipment (HBO).

Comparative characteristics for VAZ-2109

Perhaps there are also personal reasons for re-equiping their VAZ-2109? For example, a desire to dig in the car for your own pleasure appeared. One way or another, if firmly decided to change the carburetor on the injector - we go on.

Selection of necessary details

Let's start "reworking" from the selection of a good injection system. Of the options presented in the market today, Bosch M 1.5.4. Acceptable both by price and quality. It is better to set the system without any additions. It is possible to establish an outdoor gas station, but the conduct of such an operation will require additional investments. It will be necessary to buy additional details, and they are quite expensive.

To install the injector, buy details of serial car models. Such spare parts are well tested and, as they say, "tested by time."

Required:

• air filter box;
• collector;
• gas tank;
• receiver;
• consumables.

We begin with, thermostat, pulley and all belts. Cooling hoses and nozzles also remove.

It is necessary to change the benzobac. You can "borrow" from the injector model of the VAZ or buy a new one. Before installing the unit ished and dried. By installing an electric fuel pump, make sure that the arrow on it coincides with the similar labeling on the gas tank. Check that the sensor float accurately defines the fuel level.

To mount the ignition module and the cylinder sensor, we do two holes for the installation of aggregates under the bracket (20 and 16 mm, respectively). To carry out this operation, it is required to drain Tosol and dismantle the radiator.

You need to re-equip the cooling system for functioning in new conditions. To do this, change the nozzle and the temperature sensor. Additionally, it will be necessary to drain the oil, remove the pallet. We establish a new damping pulley instead of regular.

For demanding in terms of power consumption of the injection system, we establish a more powerful generator. You can choose the desired option in any specialized store.

We pave the wires, connect the devices

We carry out preparatory work in the following sequence:

• we drain the fuel (facilitate the tank);
• disconnect the terminals and remove the battery;
• we dismantle the element trambler;
• remove the fuel pump;
• we remove the carburetor;
• disconnect the ignition wires located under the hood;
• remove fuel tubes;
• we dismantle the benzobac and the vacuum amplifier hose.

Connect:

• the cable remaining from the fan relay, closer together with the instrument switching sensor;
• mount to regular fuses, relays and controller;
• connect the fuel pump to the dashboard;
• install the collector.

Separately, you stop on the fuel system - this is the most difficult operation. Install all items need to be installed on the bottom of the machine. It is especially difficult to stretch the cable under the steer. When everything is done, fasten the fuel hoses and filter well. Install the gas tank to the regular place and connect the fuel line. At this stage of the work, pay close attention to the correctness and reliability of the attachment of all pipes, hoses and masses. Do not hurry. Check out everything in detail. After installing the equipment, eliminate the shortcomings will be incredibly difficult. Making advantage of the correctness and reliability of fixing all the elements, connect the air filter, nozzle and crankcase ventilation hoses.

When all operations are carried out, we turn the ignition. The engine must work without failures. Connect the gas analyzer and diagnostic scanner (DST-2). Next, we drop errors and adjust the composition of the fuel mixture when the engine is idling at idle.

Output

No matter how much disputes about or progressiveness and the economy of the injector, in any case the choice should be done, of course, you. In order to properly re-equip your car, at all stages, follow the instruction manual and the technical passport of each node and the unit. Remember that the car is an object of increased danger and each of its action thoroughly check.
