PEMS testing

Portable Emissions Measurement System (PEMS) testing is a process of measuring a vehicle’s real-world emissions on the road using a highly accurate measurement device. When it comes to collecting emissions data, the California Air Resources Board (CARB) encourages on-road testing to understand how the vehicle performs in the real world. Driving on the road is considered “real-world driving” due to outdoor factors such as weather, road conditions, traffic, etc., which are difficult to simulate on a chassis dyno. The PEMS effectively helps us analyze vehicle emissions while incorporating these outdoor factors. Emissions commonly measured with the PEMS device include Carbon monoxide (CO), Non-methane hydrocarbon (NMHC), and Oxides of Nitrogen (NOx).

随着法规的日益严格，制造商必须改进其测试方法，以确保达到监管机构设定的标准。 CARB 已经在进行 PEMS 测试，制造商也应如此，以确保其车辆在实际应用中符合标准。

WinterPark has invested in an AVL GAS PEMS iX 493 unit. This is the same device used at CARB’s test facilities. This unit complies with the requirements of the EPA (CFR 40-part 1065), the EU (582/2011 Annex II requirements for EU In-Service Conformity testing), and CARB. With this device we can help manufacturers from all over the world acquire on-road data for regulation use and to ensure they are meeting emissions standards.
