VAZ 2107 in detail about fuel consumption
Content
The fuel consumption of the VAZ 2107 per 100 km depends on many factors. These include such as: vehicle speed, engine type and fuel supply system. What is the fuel consumption of a VAZ 2107 with a carburetor? According to the documents for such a car model, the average fuel consumption on the highway is 6,8 liters, if the speed is about 90 km / h. Pwhen driving in urban mode, this figure increases significantly - up to 9,6 liters.
What you need to know to save fuel
Checking the air damper in the carburetor
Higher fuel consumption on a VAZ 2107 with a carburetor engine occurs if the air damper is not fully open. What is its correct position? Surely, an experienced driver knows that when the engine is running in the car, the damper in the carburetor must be in a vertical position. The choke handle must be fully extended towards you. The idle fuel consumption of the VAZ 2107 can be reduced by specially setting some cover for the carburetor air damper. But, such manipulation is not effective enough.
| Engine | Consumption (track) | Consumption (city) | Consumption (mixed cycle) |
| 1.3 l 4-mech (gasoline) | 7.8 l / 100 km | Xnumx l / xnumx km | 10.5 l / 100 km |
| 1.4 l 5-mech (gasoline) | - | Xnumx l / xnumx km | - |
1.5 l 5-mech (gasoline) | 5.2 l / 100 km | 8.9 l / 100 km | 7 l / 100 km |
1.6 l 5-mech (gasoline) | - | 8.5 l / 100 km | - |
1.3 l 5-mech (gasoline) | Xnumx l / xnumx km | Xnumx l / xnumx km | Xnumx l / xnumx km |
The reasons for the high fuel consumption of the VAZ 2107, the carburetor of which is out of order, speak for themselves. Young drivers do not always take the time to check the quality of the car, and this can lead to negative consequences. Other factors of uneconomical fuel consumption can be:
- incorrect speedometer readings;
- malfunction of the device that measures the level of gasoline in the tank;
- driving style of the driver.
Checking the fuel jet
Also, the reason for the large consumption of gasoline at the VAZ can be a fuel jet, if its holder is loose. Because of this, during different engine operating modes, much more fuel enters the cylinders than is prescribed by the norm. To avoid this situation, check the tightness of the holder. It is impossible to tighten it strongly, but, and when it is not fully tightened, this will lead to the fact that the holder can arbitrarily turn out while the engine of the machine is running. The reason for overspending is too large a diameter of the jets or their contamination.
Needle Valve Leak Test
If the tightness of the needle valve is broken, then the consumption rates of VAZ 2107 gasoline will be much higher due to the fact that fuel will be poured by the carburetor. This is due to the fact that excess portions of fuel enter the cylinders through the float chamber. If the VAZ is in good condition, thenimoy its consumption of gasoline 2107 per 100 km with a 1,5 liter engine on a city road should be from 10,5-14 liters, but in the summer - from 9 to 9,5 liters.
Excessive fuel consumption at the injector
Owners of new modified VAZ cars with a single electronic control unit may experience excessive consumption of gasoline at the injector. One of the reasons may be incorrect pressure, which is in the fuel system. Recheck the car's engine management system, it may have malfunctioned.
Also, one of the key fuel consumption problems can be the failure of the injector or temperature sensor, oxygen. Fuel consumption of Lada 2107 per 100 km with an injector (engine size 1,5 l) in winter in the city should be 9,5-13 liters, and in summer - 7,5-8,5 liters.
General Factors
In addition to the considered reasons for the consumption of VAZ fuel separately for the carburetor and separately for the injector, there are others that are common to them:
- insufficiently warmed up engine;
- the catalyst is out of order;
- the air filter is dirty.
What needs to be done to optimize fuel consumption
Try to drive without sudden braking and without sudden acceleration. In order for the real consumption of the VAZ 2107 not to exceed the norm, replace the use of mineral motor oil with synthetic one.
The consumption of gasoline 2107 per 100 km (and regardless of the kilometers traveled) at normal vehicle speed also depends on the quality of the fuel, so try to purchase it at large network gas stations. Fuel savings and your financial resources depend on the technical condition of the car.
