Maintenance of heavy trucks : an international study on truck drivers
Sebastjan Škerlič, Edgar Sokolovskij, Vanja Erčulj, 2020, izvirni znanstveni članek

Opis: Since the implementation of modern approaches in operation maintenance, drivers are expected to be integrated into the entire system of maintenance in order to take over the professional competencies of maintenance workers. For this purpose, an international study was conducted on a sample of 249 truck drivers, with the aim to determine how maintenance in transport companies affects the role of heavy truck drivers in fleet maintenance. Based on the developed SEM model, it was determined that building an efficient maintenance infrastructure in transport companies enables the active participation of truck drivers in the company’s maintenance system. Drivers are capable of repairing minor failures, but only if they are proactive, which will affect their preventive behaviour. This can greatly benefit transport companies, as the results show that the vehicles are utilised more efficiently and in a better technical condition. The results therefore represent an important guideline for improving maintenance in transport companies, developing new competencies of truck drivers and upgrading existing knowledge in the development of modern operation maintenance.

3D-CO2-modelling for waste management in Styria/Austria
Wolfgang Fischer, Danko Simic, 2016, izvirni znanstveni članek

Opis: The paper in hand focuses on a calculation model which had been developed for calculating the CO2 production of a garbage truck during a waste collection tour. The challenge is the integration of not only the distance and loading weight but also the different petrol consumption and therefore CO2 production in regard to the topography of the whole collection tour. Additionally the increase of waste load at each stop during the whole collection tour has to be taken into account for the calculation. The model has been developed on basis of Excel. In order to get the real data from the collection tours these had been accompanied. There not only the whole tour but also all waste bins and stops for loading the waste had been registered. Both GPS (Global Positioning System) and RFID (Radio-Frequency Identification) had been used. The huge amount of data had to be scrubbed. This process of amending or removing data in a database that is incorrect, incomplete, improperly formatted, or duplicated was an important step to have reliable data for further calculation processes. The identification of the CO2 production during a waste collection tour including the topography and continuous revenue load had not been done so far and allows the identification of tour segments with lower but mainly higher or very high ecological impact. However, this is the basis for further discussions about options for optimizing the actual tours and habits of waste collection. That approach is part of a more comprehensive investigation of waste collection tours with general focus on economic, ecologic and social potentials for optimization.

The practical CFIE match to power articulated truck engines
Anton Černej, Želimir Dobovišek, Breda Kegl, 1996, izvirni znanstveni članek

Opis: Basic requirements related to fuel injection system of upgraded turbocharged articulated truck diesel engines are listed and discussed. An example of the FIE matching approach to upgrading of a heavy duty diesel engine is presented. The application of hollow cam fuel injection pump may offer a further extension of its use in order to uprate diesel engine performance.
Ključne besede: Diesel engines, fuel injection, trucks
