From the article you will learn how to make a blendelambda probe with their own hands and whether it is worth it to install on your car. On how well the fuel-air mixture burns in the engine, its efficiency depends. It is very important to choose the optimal proportion of the content of gasoline and air, depending on the load on the engine.
If in old cars all the quality settingsand the amount of fuel depended on carburetor adjustments, in modern times it is somewhat different. All is given in reliable hands of microprocessor technology and a huge number of sensors.
We can distinguish several of the most important nodes that are available in the injector system:
It is in the latter that the blendelambda probe. With your own hands ("Lancer 9" or "Lada" for you, it does not matter) it can be done quite simply. But it is necessary and aware of all the consequences of installing a "stub". The deception of the lambda probe with its own hands on the "Prior" can be made and a simple design, in any case it will have a significant impact on the engine performance.
Oxygen sensors (lambda probes) are mounted inExhaust system of modern cars with an injection system of fuel injection. There can be either one or two oxygen sensors in the system. If one is installed, it is located after the catalytic converter. If two, then before and after.
And one measures the percentageoxygen immediately out of the cylinders and sends its signal to the electronic control unit. The second, which is mounted after the catalyst, is necessary to adjust the readings of the first.
All automotive electronics that respondsfor the correct formation of a mixture, participates in the distribution of fuel by injectors. Using the oxygen sensor, the required amount of air is determined in order to form a quality mixture. Due to the fine tuning of the lambda probe, it is possible to achieve a high degree of environmental friendliness and economy.
The fuel burns completely, at the outlet of the pipepractically pure air is a plus of ecology. The exact dosage of air and gasoline is a benefit in saving fuel. Of course, the catalytic converter, combined with oxygen sensors, ensures stable operation of the engine. But due to the fact that it is made of precious metals, its cost is extremely high. And if it fails, the replacement will be a pretty penny. Therefore, a thought arises: "But there is a deceptive lambda probe, with their own hands (VAZ-2107 even needs to replace the oxygen sensor) it will not be difficult to do."
The appearance of this device is simple - longelectrode-body, from which the wires depart. On the body plating of platinum (it was about this precious metal that was discussed above). But the internal device is more "rich":
The two main types of oxygen sensors, which are currently used in automotive engineering:
Regardless of the type, they have practicallythe identical device is internal. External similarities, as you know, are also there. But the principle of work is very different. The broadband oxygen sensor is an upgraded two-point sensor.
It has a pumping component, which,due to voltage fluctuations, provides a signal to the electronic control unit. On this element, the current supply can either increase or become weaker. At the same time, a small amount of air enters the gap and is analyzed. It is at this stage that the CO concentration in the exhaust gas is measured. But sometimes the lambda probe is made and installed by its own hands. "Chevrolet Lanos", for example, works with it stably and does not give errors after refueling with bad gasoline.
Of course, this element is not eternal, in spite ofits high cost and platinum in the composition. Of course, the lambda probe is no exception and at one point can order a long life. And there will be some symptoms:
If it is not possible to analyze the exhaustgas with a special device, you can do it visually. Light smoke is a sign that there is too much air in the fuel mixture. Black is talking about a lot of gasoline. Therefore, one can judge the system's malfunctioning. But the picture is different, if there is a deceptive lambda probe. With their own hands ("Volkswagen", VAZ, "Toyota" - for any car) such a device is made quite simply.
It is worth paying attention to the fact that the sensoroxygen is located in the epicenter of fuel combustion. Consequently, the composition of gasoline has a significant effect on the work of the lambda probe. If gasoline contains a lot of impurities, does not comply with GOST, low quality, then the oxygen sensor will give an error or an incorrect signal to the electronic control unit. In the worst case, the device fails. And this happens because of the high content of lead, which is deposited on the sensor and breaks its functioning. But there may be other causes of breakdowns:
Try to carry out diagnostics of your car from time to time. In this case, it will not be a surprise for you to fail any element.
Of course, the most accurate answer about breakdowns will giveonly diagnostics on specialized equipment. But to detect the breakage of the sensor it is possible and independently, it is enough to read carefully about the features of the sensor and its characteristics. But it is very rare to set up a lambda probe. With your hands (VAZ-2114 or any other car if you have) make a stub-blend can be from improvised tools in the literal sense. The algorithm for troubleshooting is as follows:
You can also judge the failure of other characteristics. In a vacuum tube, you create an artificial vacuum. At the same time, the voltage should be very low - less than 0.2 Volts.
To ensure an uninterrupted and stablework of the car, it is necessary to carry out regular technical inspection. For example, a lambda probe needs to be inspected every 30,000 kilometers. And the resource at it no more than hundred thousand - it is not necessary to maintain the car with the old gauge - it only will lead to that the engine should be subjected to repair much earlier. And the question arises: will the lambda probe fad suit your car? With their hands on the "Kalina" such a device can be done in a few minutes.
But there is one nuance. The motorist can not guarantee that the fuel with which he runs the car is of high quality. Of course, everyone is accustomed to pour the gasoline that is sold at his favorite gas station. But who knows what is the composition of the gasoline that is bottled there? Therefore, try to trust the gas stations "branded", who cherish their name. But if there are not a number of good gas stations, then you will have to be satisfied with what is available at your side. And a burning ICE error lamp - this is a frequent phenomenon, to get rid of which will help to install the blende.
It all depends on what means youhave. It is worth noting that the deception of the lambda probe with its own hands on the WHA can be the most democratic, it still works without fail. The cheapest option - home-made. A bronze body is made. This metal is better to choose, because it has a very high resistance to heat. And the dimensions of this blob should be exactly the same as the sensor itself, so that the exhaust fumes do not leak. In fact, this spacer with a small hole - no more than three mm. This spacer is screwed into the sensor position. And the lambda probe itself is installed in the spacer.
Between the sensor and the hole in the disc is locatedlayer of ceramic chips, on which a layer of catalyst is applied. Due to this, the exhaust gas passes through a thin hole and is oxidized by crumb. The result is a significant reduction in the level of CO. Consequently, the standard oxygen sensor is deceived. But such devices can be installed on budget cars. More expensive machines should not be altered.
But if there are skills in installing electrical circuits,you can make a homemade device. You only need one of these two elements - a resistor or a capacitor. But not for all fit such a deceptive lambda probe. With your own hands ("Subaru Forester" or VAZ, it does not matter) you can make it according to one of the suggested options. But be careful, because a misunderstanding of the process of the deception will affect the functioning of the entire control unit. And if you are not sure, you better get ready on the microcontroller. It is good that it can independently carry out the following actions:
The most effective way is to completely changeprogram, embedded in the control unit. The essence of the whole procedure is to get rid of all or part of any reaction to the change in the readings coming from the oxygen sensor. But pay attention to the fact that the warranty is lost on the car. Therefore, for new machines such a method, as, indeed, any other, will not do.
And most importantly - think about whether the ovchinkadressing? Do you need to do such a detail, as a deceptive lambda probe, with your own hands? "Lancer 9", say, the car is not budget, but high-end, so is there any sense in breaking its design with various homemade products? Is it reasonable? If there is money for an expensive car, then there must be funds and to maintain it in working order. If not, why did they buy such a car?
