AGAIN ON Homogenizers
About zarihritelyah combustible mixture of the form with fixed blades under the carburetor, the journal was mentioned many times.
Published and the comments of the expert and the opinion of readers. The positions of the authors were similar to employ such devices there is no reason. Nevertheless, the questions on this subject is not exhausted. The reasons are clear. First, swirlers (also called a homogenizer) is widely sold and enticing advertised by their manufacturers (factories and cooperatives), and secondly, motorists want to have a reliable practical information about what tests show homogenizers conducted a competent research organization. This interest is natural, and we will try to satisfy it.
So do a lot of different swirlers. Among them are such that even the eye is not quite at odds with the aerodynamics, and is very accurate. The latter include the so-called Kono homogenizer,
developed by inventor J. Elshanskim and manufactured by the Moscow New cooperative. This product has been tested at the Volga Automobile Plant with a perfect research equipment and strict testing methods of branch operations. The latter fact should be particularly emphasized, since this is what distinguishes this work from a large number of evaluations and audits that have taken place and various non-specialized organizations, or simply in amateur conditions. The tests included in the WHA and the experiments with the engine on the engine stand, and check directly to the car.
First of all, let us turn to the content of carbon monoxide (CO) in exhaust gases when the engine at low idle. For motorists, this indicator is important primarily because it is subject to control by the traffic police. Happened in the next series of experiments. CO content in exhaust gases with the same spacer, and without it. At the same time it became clear that this parameter is highly dependent on temperature, primarily gasoline in the carburetor. If you do not provide the full extent of the experiment, can get a significant advantage of any of the options. Apparently, this is one of the main reasons why developers with products, like, the objective conditions are watching an impressive difference, and then use it for advertising.
On the engine stand was estimated impact on the cardinality swirler performance engine. It was found that in the range up to 4000 revolutions per minute presence of an additional element not overpowering. There is no improvement from the turbulence of the mixture, or deterioration due to noise in the intake tract. But after 4000 rev / min flow rate increases in the pipeline so that the interference comes into play and removes the limit of 3% of the maximum engine power. Practical value, this loss has little, but fact is fact. As for the maximum torque, it remains the same as achieved at speeds less than 4000.
Motor Stand allows for a more interesting experience to identify the so-called used engine power. To do this, every time a certain speed of rotation of the engine brake torque load, corresponding to the amount of road resistance (air bearing) during the uniform motion along the highway to direct transmission. In other words, simulates real riding, but, so to speak, in a very pure form. Here, cardinality indicators with spacer and without a fully matched in the whole range of measurements (up to 4700 rev / min, which corresponds approximately to 120 km / h). But more interesting were almost similar and the curves that characterize the fuel consumption. Some of the difference is not in favor of the spacers, but insignificant.
