Water brake chassis dyno restoration – VIGA Auto Tuning

Task:

VIGA Auto Tuning is a specialist tuning shop in south Poland that acquired an old water brake chassis dynamometer. The stock control system for the dyno was outdated and out of order. PEREK dynamometer controller were contacted to provide a cost-effective solution to get the dyno working.

Solution:

The water brake was fitted with a circuit consisting of a water pump, pressure regulator and PWM controlled inlet valve. Brake outlet uses a manual valve to control brake water discharge. Another PWM valve for water outlet is planned in future to increase the brake control speed. Dynamometer brake control and data acquisition is performed by a low cost DC1L dyno controller. The dynamometer is now capable of loading vehicles with additional torque from water brake. This allows it to be used to measure power of more powerful turbocharged cars that require additional load to spool up the turbo. Despite DC1L low cost, it is powerful enough to get the water absorber dynamometer running and still have some spare inputs for innovate AFR/lambda sensor signal and additional temperature probes.

Mobile dynamometer at Fiat 126 fans gathering in Poland

This August, many fans of the Polish Fiat 126 “Maluch” gathered in Opole. Świątek company came to the event to provide dyno services with their mobile dynamometer powered by PEREK DC1 controller.

The Fiat 126 is a four passenger, rear-engined, car that became a people’s car, and a cultural icon, earning the nickname Maluch (“The Little One”). It was the most common Polish car in the 1980s.

The stock engine with 594 cc capacity was able to produce 23 hp, however as we can see some fans of the “Maluch” managed to nearly double that power.

Absorption engine dynamometer – AQUARIUS ENGINES

Industry leader in modern power generators

AQUARIUS ENGINES develops its high-efficiency engine on the engine dynamometer, based on PEREK and Ecumaster products. The stand was designed and made by the Świątek company.

Task:

AQUARIUS ENGINES needed a tool to work on an innovative motor for power generators. It was required to be able to load the engine for a long time and work in constant conditions. Along with measuring engine power, it is necessary to monitor many other parameters of engine operation and the environment.

Solution:

The company Świątek from Bydgoszcz undertook the implementation of the project. The dyno is a separate room in the building. The room is protected against electromagnetic interference and is equipped with a complete ventilation and fire protection system.

The PEREK integrated dynamometer DC1 controller is responsible for the control and measurement part of the dynamometer. The controller, in addition to the sensors necessary to control the dynamometer, allows you to connect 6 analog 0-5V signals and 8 thermocouple temperature sensors. Thanks to the functionality of the CAN bus, it is possible to integrate the controller with other systems of the dynamometer.

The engine load is provided by the Elektromex water-cooled eddy current brake. The brake is powered through the BD1 eddy current brake interface from PEREK which receives the control signal from the DC1 controller.

ATV Dyno – Rafał Sonik

Polish entrepreneur and winner of the Dakar Rally

Rafał Sonik is a Polish entrepreneur who has been winning in quad rallies since 2001, including the famous Dakar Rally.

Task:

Rafał’s team independently built an inertial dynamometer dedicated to work on ATVs. The dyno is compact and convenient to carry when it is not needed. It is equipped with special ramps and mounting points designed for work with ATVs. The only thing missing was a measuring system. The inertia of the dynamometer rollers was known from the CAD program, but the inertia of additional elements rotating with the rollers was unknown.

Solution:

The dyno was brought to life by a universal PEREK dyno controller. The inertia of a set of rollers and wheels of the quad was measured by accelerating the entire set with a falling weight on a line pulled through the pulley. The dynamometer is now ready to contribute to Rafał’s next successes.

Chassis dyno – Ecumaster

Automotive electronics manufacturer

Ecumaster is one of the fastest growing companies in the motorsport and tuning electronics industry. PEREK works closely with Ecumaster, developing intelligent electronic solutions for the automotive industry.

Task:

The dyno was controlled by software running on an outdated computer. Upgrading the computer was impossible due to the software’s compatibility only with specific computer components – motherboard and sound card. A failure of the dynamometer computer would result in the need to look for specific old components on the used parts market.

Solution:

A PEREK dynamometer controller was used to control the dyno. The controller works with the already installed rotation sensor and toothed wheel. The dynamometer has been calibrated to the inertia of the rollers based on the settings from the old software. The controller is mounted on the back of the dyno TV and is equipped with a wireless keyboard and mouse. The cabinet containing the previous desktop computer has become redundant.

PEREK Dyno in TVN Turbo TV

Grzegorz Duda paid his visit on the PEREK dyno placed in Ecumaster workshop. Grzegorz needs no introduction, motoring fans know him from the programs of 101 repairs and “Garaż Dudy”. Artur Kisielwski, who operates the PEREK dyno, had the pleasure to help Grzesiek prepare the Mini for a duel with Adam Klimek.

Visiting the dynamometer created by Perek Dyno, tuning the car and uploading sports maps, was the icing on the cake in preparing the Mini for the final battle with Adam Klimek’s car.

You wonder who won and if the engine on the dynamometer did explode? We invite you to watch Klimek kontra Duda – odc. 10 sez. 1.
