We have a modern and advanced 4x4 VT-4/B2 evo chassis dynamometer, which we use for precise measurements of the performance and results of our modifications. Thanks to this, we can accurately assess the outcomes of our work and provide our clients with the best services.
Equipment of our dynamometer:
- Blower fan (20,700 m³/h)
- Exhaust fan (3,700 m³/h)
- Additional data logger for sensors (8 inputs)
- AFR sensor
- Boost pressure sensor
- Temperature sensor (thermocouple 0-1200°C)
The mechanical synchronization of the front and rear axles allows measurement of the latest all-wheel drive vehicles equipped with an advanced torque distribution system between axles. It also enables correct measurements of vehicles with single axle drive equipped with the latest traction control systems, which require all wheels to be in motion during measurement.
Measuring capabilities of the VT-4/B2 evo dynamometer:
- Inertial mode
The vehicle is accelerated on the dynamometer to a speed selected by the user, and then, after disengaging, the vehicle rolls without drive until it stops.
The load for the engine in inertial measurement includes the mass of rollers, rolling resistance, and drive mechanism resistance. The measurement time is about 10-20 seconds of full load and a few minutes of free rolling on the dynamometer until stopping. Power and torque are measured as functions of the vehicle's acceleration on the rollers (power and torque at the wheels) and its deceleration (loss power and torque). Their sum creates a result representing the engine's power and torque. - Dynamic load mode
The measurement proceeds similarly to inertial mode, except that the eddy brake simulates a greater load on the system. The load indicator is a percentage value determined in the dynamometer software by the user. This mode allows for extended measurement time and proper loading of the vehicle, which is recommended for measuring very powerful turbocharged engines. - Constant speed mode
The measurement involves balancing the vehicle's driving force using the eddy brake. The measurement time is about 10 seconds of full load (for stabilizing revolutions and reading results) for each measurement point (specifically selected revolutions). Power at the wheels for each measurement point is calculated based on data from the load cell and displayed in real-time on the screen. - Road mode
The vehicle accelerates in a manner similar to road conditions. The eddy brakes, based on input data, generate a load similar to forces resulting from air resistance and inclines, depending on the current speed of the vehicle. - Driving cycles
The ability to perform so-called driving cycles according to a self-configured scheme or selected from the available database (e.g., EUDC test simulating driving in non-urban conditions). Driving cycles are used, among other things, to test exhaust emission levels, fuel consumption, etc., or to calibrate LPG/CNG installations.
We cordially invite you to check your vehicle's performance and to perform modifications.
Dynamometer - information
In today's world, there is a continuous development in the automotive industry, which also increases the number of its enthusiasts. Cars, which until recently were merely a means of transport for most, have now become devices that everyone wants to enhance and enrich their knowledge about. Power measurement on a dynamometer is intended for those who want to know as much as possible about their vehicle. A dynamometer is essentially a measurement station that provides information to determine the performance characteristics of an engine. The power measurement on our dynamometer is possible in several different modes: - inertial mode - dynamic load mode - constant speed mode - road mode - road cycle The diversity of our offer ensures that the power measurement on the dynamometer will be accurate and tailored to every type of vehicle. We can meet your requirements even for Japanese-made cars. Checking a vehicle's performance is just the beginning. The next step is the option to modify our vehicle, which will undoubtedly please tuning enthusiasts. Every car enthusiast would like to extract as much as possible from their vehicle, so the opportunity to increase the power that our car was originally designed for is undoubtedly a reason for joy. We offer you the possibility of obtaining extremely accurate and detailed knowledge about the current performance of your vehicles, which brings the option of implementing advanced enhancements. It is also essential to remember to adapt the modifications introduced in the car to its current capabilities to avoid straining the engine and causing any other damage. We are confident that our presented offer will meet your expectations. The services we offer are prestigious in the market, as evidenced by the fact that our clients return to us to use our services again and recommend us to others. Caring for vehicles has always been and will always be our priority, so you can safely entrust us with your car.
