What our technology of the measurement of power - Vtech dyno - is offering to you ?

Gigantic speed of collecting the information

Fundamental flaw in solutions of dynos existing on the market is their frequency of the sampling. On graphs from dyno of see many companies one can see clearly a few or a dozen or so lines, from which the shape of characteristics is estimated. Of course smoothing the graph with curves is also possible but whether can we call it the actual result? Usually the power and the torque is sampled on dyno every 0.3-1.0 sec. and the established result is de facto the average power and the average moment in such a time interval. In the effect of such techniques measuring twice the rotational moment which changes violently (as in turbodieslels) is giving two different results. It depends how ranges of the sampling will overlap.

A few years ago our company invented the new technology of the measurement of the rotational moment which applied both to braked dynos and inertial dynos. The method of the measurement was planned originally for laboratory measurements of the power but it is also in our trade offer. The method is based on TrueForce™ technology patented by us (reserved Vtech sign), which allows for measuring the torque completely smoothly (fluently). From a point of view of the speed of the changes of power on dyno, the measurement is being made in the real time and with the unbelievable accuracy. In fact in every second of the measurement the trans-coder of the dyno is providing five thousands informations about momentary value of the torque and the power - one independent measuring point is being put on the graph every 0.0002 second. The error of determining the temporal moment is smaller than 0.000015 s. (fifteen millionths of second). Furthermore, such an accuracy is being offered in standard version - it is possible to measure faster - it is depending only on the speed of the transcoder applied. Changes are smooth on graphs. Why? Because the work of an engine and changes in the moment also are not violent, on account of the great own inertia. The accuracy of the measurement is high so the graph is smooth and the line is not wobbling, but stopping of the measurement or the smallest disruption is „mercilessly” picked up and it is possible to point exact rotations of the engine for which it appeared. It is possible to observe subtle phenomena, like temporary resonances, slip of wheels (position of the rolls at any time is known within the accuracy of fractions of the degree) or minimal loss of torque at balancing the pressure. What's more even single escaping ignitions are lowering the torque of the engine and they are visible in spite of the existence of the flywheel! Furthermore - results are reproducible in many tests (of course if we are caring about keeping the fixed temperature of the engine and we aren't repeating tests one after another too many times) -as far as we want. And everything without any smoothing, without the averaging, without counting by the imaginary per cent and rates. No other solution is offering such an accuracy and precision - you must simply see it in order to appreciate possibilities of the TrueForce™ system fully.

The very big accuracy of the measurement and the high repetitiveness

An advantage, resulting straight from our innovative method of the measurement, is a really big repetitiveness. Since rotations of roll are being measured up unusually exactly, measurements of the torque and the power and a positioning of points on the graph are also accurate. On account of good (lozyska), the great inertia and the smoothness of rolls and very precise balancing of rolls, the accuracy of the measurement is also higher than in different rival solutions. Moreover, the dynos are being calibrated with the use of the gravitational model (wzorzec) of the torque - what is guaranteeing appropriate values of absolute measured parameters.

The possibility of the easy expansion and the modularity of solutions

Probably everyone who is deciding to spend several dozen thousand zloties on a device such as a dyno, would like to know, what next, what to do, when his needs will grow.

Our solutions are entirely modular. It is possible to exchange rolls in them (three accessible different versions of the weight of rolls - 125 kg, 150kg, 180kg), to install electro-spin brakes, to extend one-axe dynos to 4x4 (inertial or braked). All necessary measurements and conditions of the building development for given options can be provided in advance in the form of plans - so the user can (przymierzyc) the possibilities ofhis room designed for the dyno also assuming its future expansion.

The fact that it isn't necessary to invest a lot of money at once is another advantage resulting from the modularity. If the deviceyou dream ofis a mighty 4x4 dyno with two brakes and full accessories to laboratory measurements - you can start by purchasing inertial dyno - to install the brake next, after that the second axis, finally the other brake and sensors together with the measuring card. Everything like from Lego blocks.

The popularity and the credibility of the producer

As many as over 20 companies at home and abroad chose our solution - including many known and popular Polish tuners and specialist companies! We are the biggest producer of dynos in central Europe. You can meet graphs produced by our measuring system everywhere - in the Internet, in newspapers, in hands of the ones which are testing their cars on our dynos. Results from our dynos are coinciding with themselves thanks to the calibration of a ready dyno in our company. Our system is known universally. The most dynos in Poland are produced by Vtech. You can examine our dynos not only in (business premises) in Cracow - but also in Warsaw and surroundings, Lublin, Lodz, Piotrkow Trybunalski, Zgierz, Rzeszow, Bilgoraj. We are installing only in Poland one dyno monthly. Abroad our dynos are working in United Kingdom, Ireland, Germany, Lithuania and Latvia.

Impeccable workmanship raising the prestige of the owner

Our dynos are being made on steel frames, covered with fitted lids of (ryflowanej) brass, galvanized or painted twice and conserved. Rolls are made with the method without edges (welds and balancing weights are not visible) are next knurl (?) and covered with technical chromium. Lifts raising cars are covered with specially shaped porous lids. The controlling computer is being put in professional industrial casings -driver of the electro-spin brake also. The whole of steering is put in the 19’stand - standard of industrial frames. We are delivering all needed elements in the set. Address data of the buyer is being presented on printouts and protocols - and the graph can have any logo as the background – preferably the logo of the company of the customer.

Which dyno should you choose?

Since dyno isn't a cheap device, it is well to know exactly which options you need, which you should resign or invest in them at a later date - in the measure of the increase of needs and loads of your dyno. Perhaps you already know specifically for a long time what you need - or you formed an opinion having read the above description of functioning of individual types of dynos. If you aren't sure – the table below can help with appropriate choice.

How to buy a dyno?

First you should decide, which dyno will meetyour expectations best, choose an option and set of sensors which will of use for you and determine possibilities of future upgrade of the system. Next you must make sure that the room for dyno is fit for it and basing on the project delivered by Vtech – plan its localisation, powering, the space for the steering system (computer), and anchors permitting to secure car. If you already make a decision about buying the device, you order the specified version (you are signing the written order form, tying for both pages). You are making the advance payment. Vtech is determining the dyno delivery time - terms are vacillating from 2 weeks to 3 months - depending on the complexity of the order. Our specialists will bring in the time  due the  dyno to you - however you must prepare earlier the foundation for it , according to the plan. Dyno is installed and started during one or two working days (dyno is being calibrated still in the factory, in Cracow). Your staff is left trained (operating manuals for the dyno are also being provided in the printed and digital form). You can start measurements.

You can choose a few ways of financing. Simplest is a payment of the advance payment and a surcharge for the 100% of the price at installation of the dyno. It is also possible to lease a dyno. Among others, European Leasing Fund and Volks Bank Leasing are taking on such a service.

Guarantee

The Vtech company is guaranteeing correct and failure-free functioning of the dyno and no faults in mechanisms during the period of two years. After the guarantee period our company is proposing paid inspections by the authorised staff - during the first month of the next year of the exploitation. Making the prompt inspectionprolonges the guarantee to the next year, through the period of 7 years from the date of the purchase. The normal and prolonged guarantee is not valid for elements which will be destroyed or worn out by the wrong exploitation or application of wrong materials (it concerns bearings in the particular). We are testing the calibration during every inspection of your dyno. Such rules of the guarantee are legible and permit the purchaser to feel secure through the entire period of using dyno - that is many years.
