AVL Motortestcenter AB (AVL) has on commission by the Swedish Transport Administration tested a wheel loader of emission standard Stage IV (Volvo L220H) with Portable Emissions Measurement Equipment (PEMS). Regulated emissions (for engines); carbon monoxide (CO), hydrocarbons (THC), nitrogen oxides (NOx) as well as fuel consumption (FC) and CO2 were measured. The test location was the test grounds of Volvo Construction Equipment (VCE) located in Eskilstuna. The machine was tested in different test cycles, all representing for NRMM normal operating situations which could possibly be challenging for the exhaust aftertreatment system. The drivers used were VCE employees, all skilled NRMM drivers. Several tests were performed and evaluated both as whole tests and according to the averaging window principle based on work and CO2 mass emissions, as proposed for In-Service Conformity Procedure for Nonroad Mobile Machinery in EU.
