Dynamometer Engine Testing

Major American automobile manufacturers trust PCC’s dynamometer engine testing.

Process Combustion Corporation’s recuperative thermal oxidizer system has been selected by automotive engineers, consulting engineers, environmental engineers, and engine testing personnel as the most reliable emission control technology for engine dynamometer testing applications.

Why us?
PCC supplies most major American automobile manufacturers with state-of-the-art recuperative thermal oxidizer and non-recuperative thermal oxidizer systems. Our pollution control equipment is not only designed to reduce emissions from engine testing facilities, but also to meet or exceed all Maximum Achievable Control Technology (MACT) standards for dynamometer engine testing applications.

Put to the test.
As part of the automotive industry’s constant commitment to product develop and product reliability, all automotive manufacturers conduct rigorous engine testing, engine part testing, transmission testing, and other tests, as part of their research and development programs. Engine testing is generally conducted using engine dynamometer test cells installed in the automotive manufacturer’s engine production plant.

The engine dynamometer test cell (sometimes called “dynos”) is a highly instrumented and tightly controlled room in which the engine is directly coupled to the dynamometer. The sophisticated dynamometer allows the automotive engineer to simulate “real world” engine operating scenarios along with engine durability tests, engine performance tests, combustion analysis tests, engine emission tests, and other tests all aim at improving engine performance. As one might expect, engine testing generates exhaust emissions, which can contain high levels of carbon monoxide (CO), unburned hydrocarbons (UHC), nitrogen oxides (NOx), hydrogen (H2), sulfur dioxide (SO2), and carbon particulate. Under the new MACT standards, new or reconstructed engine test cells/engine test stands that test internal combustion engines with a rated power of ≥ 25 hp must limit emissions of carbon monoxide and unburned hydrocarbons: Many state implementation plans (SIP) require NOx emission limits as well.

We aren’t kidding when we say that most automotive manufacturers have selected PCC’s recuperative thermal oxidizer system to address these emission control issues. Designed specifically for the uniqueness of every dynamometer engine testing application, PCC’s recuperative thermal oxidizer system offers advantages for every engine testing application:

    • Custom designed specifically for each engine test application
    • Designed for idle and wide open throttle (WOT) engine conditions
    • Proper engine exhaust collection header design that does NOT impact engine testing in any adverse way
    • Fuel efficient design features which minimize operating cost
    • Robust and reliable equipment reduces maintenance and repair costs
    • Combustion chamber design features ensure high destruction efficiency and environmental compliance
    • User friendly PLC -based control system with operator interface screen
    • Compact equipment arrangements reduce plot space requirements
    • EXACT application designs are field tested and proven
    • Maximum safeties ensure safe unattended operation
