The Dangers of Dyno Testing

Dynamometer (dyno) testing is used across numerous industries but is predominant in the auto industry. Dynos measure the force, torque, and power output of a vehicle and are frequently used for emissions testing and mileage accumulation. Although there are many different types of dynamometers, they're all faced with the same factoring issue - temperature.

Engines running at or near capacity for extended lengths of time generate higher temperatures than a typical engine running at idle. Dynamometers produce heavy airflow at high volumes presenting an increased concentration of carbon monoxide.

When inhaled, carbon monoxide (CO) displaces oxygen in the blood and deprives the brain, heart, and other vital organs of oxygen. Based on the levels of CO and the length of exposure, technicians and individuals in the work area may experience several health issues ranging from minor to severe.

CO poisoning may happen more quickly to people susceptible, such as individuals with lung or heart disease, people at high altitudes, or smokers. If caught in time, CO poisoning is reversible. However, even after recovery, acute carbon monoxide poisoning can result in permanent damage to your heart or brain.

Dyno exhaust removal systems make dynamometer testing safe for technicians and ensure accurate test results. You can reduce the risk of CO poisoning in buildings where dyno testing takes place by implementing vehicle exhaust removal systems to capture emissions directly at the source. Other preventative measures include:

• Proper ventilation

• Maintain equipment to ensure safe operation and reduced carbon monoxide formation

• Install CO monitors with alarms

• Don't allow the use of gas-powered engines or tools in poorly ventilated areas

• Test confined spaces regularly

• Switch from gas-powered equipment to electric or compressed air (if used safely)

• Educate technicians about the sources and symptoms of carbon monoxide exposure
Fume-A-Vent dynamometer exhaust removal system installed at a performance testing facility to capture harmful gas emissions.

During dyno performance testing, a direct nozzle connection could affect the performance results of the vehicle being tested. The Fume-A-Vent team specializes in dynamometer exhaust removal and we're ready to create a custom system that meets the specific demands of your application.

Dyno exhaust removal systems use the source capture method to draw CO and other hazardous contaminants away from the exhaust point. A direct nozzle connection can impact performance test results and must be customized to meet the airflow needs of your system.

We carry dyno exhaust hoses, tailpipes, fans and blowers, duct work, portable solutions, and wall systems designed to meet custom application requirements. Let us know if you need additional assistance or request your free quote today.
