The paper presents a comparative analysis of the emission of CO, NOx, CO2 and gas mileage for two heavy-duty long haulage vehicles. The tests were performed on the same test road. The test route reflected typical daily operation of heavy-duty vehicles – a drive to the loading/unloading zone and cruise on national roads. In the investigations, the authors used a portable exhaust emissions analyzer (SEMTECH DS, PEMS – Portable Emissions Measurement System). Based on the performed analysis, optimum engine was selected for long haulage vehicles under conditions of Polish transport and logistic infrastructure in terms of fuel consumption.

In the assumptions regarding to the transport policy both at the level of country and Europe there is the concept of sustainable development of transport. Warsaw University of Technology in cooperation with Poznan University of Technology performs research work concerning the shaping of environmentally friendly transport system – Project EMITRANSYS. In this project, one of the conditions is to reduce exhaust emissions by means of transport. The paper presents the reasons for the testing of the exhaust emissions under Real Driving Emissions testing (RDE). Research potential of Institute of Combustion Engines and Transport at Poznan University of Technology in the area of road testing of passenger and heavy-duty vehicles has been presented in the paper. Example test results have been shown in the aspect of the emission-related classification of vehicles.

Heavy Duty Vehicles

In this paper, we establish a mathematical framework that allows us to optimize the speed profile and select the optimal gears for heavy-duty vehicles (HDVs) traveling on highways while varying parameters. The key idea is to solve the analogous boundary value problem (BVP) analytically for a simple scenario (linear damped system with quadratic elevation profile) and use this result to initialize a numerical continuation algorithm. Then, the numerical algorithm is used to investigate how the optimal solution changes with parameters. In particular, we gradually introduce nonlinearities (air resistance and engine saturation), implement different elevation profiles, and incorporate external perturbations (headwind and traffic). This approach enables real-time optimization in dynamic traffic conditions, therefore may be implemented on-board.
