The 4WD horsepower dynamometer is specially used to measure the chassis dynamic performance of the2WD and 4WD vehicles. It can not only accurately measure the dynamic performance at each speed, but also simulate the road to carry out the road test of routine and multi-road of the vehicles, and can also be used for vehicle refitting and ECU debugging and calibration, etc.

The horsepower machine is a piece of special equipment for testing the power of automobile chassis, and it is also a kind of chassis dynamometer. It can accurately reflect the dynamic performance of the vehicle at each speed, which is convenient for the adjustment of the vehicle's power; it uses the scientific detection method and the system inertia adaptive algorithm to accurately calculate the output power of the vehicle chassis. It can also detect the maximum speed, acceleration time (performance), etc. The control system adopts a high-speed data bus with a WiFi interface. The control computer can be a PC or laptop, which is convenient for operation. You can know your car’s condition anytime by the routine test and simulated road conditions test. It is very suitable for used car evaluation centers, automobile repair shops, automobile refitting, ECU adjustment industry.
1．Test power data: region-wide speed horsepower engine /torque curve can accurately the reaction of arbitrary rotational speed (typically2000 rpm or more)of the engine operating conditions. The most prominent is the output value of the maximum horsepower and torque.
2．Simulated on-road test: the roller of the horsepower machine can be controlled by the computer to set the resistance and simulate various resistance conditions of the road. As long as it is properly adjusted, it is safe to run dozens or even 200kW / h on the horsepower machine.
3．Diagnosis of automobile power condition: a powerful horsepower machine with clock diagnosis method. If the constant speed function is used, the horsepower engine can use the constant speed function. The horsepower engine can limit the car to the desired speed (a reasonable speed). At this time, the speed (RPM) in the same gear is unchanged. Changing the throttle opening and closing degree or ECU working parameters can get different horsepower output. It is better to cooperate with the knock receiver, air-fuel ratio meter, air flowmeter, etc, which may be better to judge the work status of the car immediately
