Opis:: Currently produced diesel engines of different manufacturers, used for the same applications, have comparable specific fuel consumption. Therefore, the laboratories measuring fuel consumption, especially in comparative tests, require the use of more accurate methods of measurement. The Environmental Protection Centre of Motor Transport Institute has recently implemented the fuel consumption measurement method using KMA Mobile flow meter produced by AVL company. This device allows to carry out measurements by both volumetric and mass method, thanks to builtin device for measuring the fuel density. Due to some customers requirements the laboratory began with preparations for obtaining accreditation of the Polish Centre of Accreditation for the procedure of measuring fuel consumption by volumetric and mass method. One of the requirements of the Polish Centre for Accreditation is carrying out the validation of the new method. It can be done by comparing the results obtained with new method with the results of the method already validated. The validated method is described in the regulation. This is the carbon balance method described in UN-ECE Regulations No. 101. The calculation of fuel consumption according to this method is based on a measurement of pollutants emissions of carbon dioxide (CO2), carbon monoxide (CO) and hydrocarbons (THC). This paper describes the fuel consumptions measuring procedure using two methods: mass method using a AVL KMA Mobile flow meter and carbon balance method using the AVL AMA i60 analyzers. To verify measurement results additionally there was fuel consumption measured with using a scale, as a difference of the external fuel tank mass change, from which the vehicle was fuelled during the tests

Opis:: A theory of cumulated fuel consumption in process ofvehicle operation is described. The method of creation the mathematical model and procedure of determination of model variables is shown. The mainfeatures of cumulated fuel consumption are painted attention. li is shown that the theory of cumulated fuel consumption can be use to description of the fuel consumption from beginning the exploitation of vehicles and also for the situation when the vehicle are in exploitation from any time and further fuel consumption are unknown. An example of utilisation of elaborated theory for assessment of operation of passenger car is also presented. It has been shown that applying the theory of cumulated fuel consumption, the course of such consumption can be accurately described also in this case. This proposal can be formulated in spite of making some simplifications. This is because the unknown value of the accumulated fuel before start the time of observation operation will be determined using the average (from the average) fuel consumption. This simplification greatly facilitates the flow of the calculations and it seems does not offend errors in the calculations. Method of determining the average is discussed in the article. It appears that such treatment may be justified by the fact that the mistake is, in principle, systematic error. Very high coefficients of mathematical model to fit the measured data are very interesting. Such regularity was observed during researches in buses transport [l], intercity buses, and the fleets of various vehicles (the results of researches are not yet published).The introduction of the theory of cumulated fuel consumption as one of the important parameters to assess the operation of the vehicle or vehicles may also be useful in exploitation researches. At present times the researches in which the vehicles are already in service and the engine control mops are tuned (chip tuning), are made. A good performance of these changes is often observed on chassis dyno but that is not properly sanctioned in natural exploitation. Experimentation with such issue is underway and will be the subject of future analysis (and publications).

Opis:: Theory of cumulative fuel consumption is shown for the first time in [1] and [2]. The theory of cumulative fuel consumption has been presented also in this work. The example of LPG car research results have shown the way of getting to mathematical model of cumulative fuel consumption and the intensity of cumulative fuel consumption. In this case, the studies were carried out 16 cars whose engines were powered by LPG. The vehicles are operated in a small fleet of vehicles, which run in city traffic. Data on outcomes of exploitation and operation fuel consumption is acquired from the accounting documents of the company. Very good results prediction mathematical model of operational data are obtained. The high value of prescience quotients (in this case R-sq > 9.999) are similar to the values that were obtained in various other cases. Conversance of mathematical model of cumulative fuel consumption allows carrying out comprehensive analysis of this significant exploitative parameter. The presented theory must not only be regarded as a theory of cumulative fuel consumption but also can be seen more broadly as a theory of cumulative energy consumption. Research is being conducted on the application of the theory to evaluate energy consumption by hybrid vehicles. The results can be very interesting.

Opis:: In the automotive industry in the world continuously being sought universal driving cycle. The test should closely match the fuel consumption and emissions of toxins in the fumes of the test vehicle in its real operating conditions [4]. However, in the previously developed solid driving tests established velocity profiles differ significantly from actual driving conditions. The difference in fuel consumption, comparing the natural operation of the NEDC test reaches an average of 18%. The new version of the driving cycle should be more realistic to the everyday use of additional equipment and gadgets that are installed in modern vehicles [1]. The impact on fuel consumption by vehicles may be conditioned not only by its size and weight, but also by the geometry of the track motion, forces causing the motion and the forces acting on the car when driving on curved tracks. The vehicle encounters and overcomes all the forces that act on it while driving-resistance movement. In the energy intake through the vehicle runs in the motor changes at the expense of the energy of fuel consumed. The driving force performs work on a given stretch of road balancing (predominant) friction. On the basis of the calculated resistance movement and the energy consumption of the movement in the selected object was a comparison of the actual consumption of fuel in the vehicle with the ignition spark. Analysis was performed and found differences in three cycles: urban, extra-urban and combined.

Opis:: The study presents a draft calculation of fuel consumption and emission of CO2, CO, HC and NOx by a engine car used in real traffic conditions. In this project, the author was inspired by the results of his own studies and those of selected domestic and foreign research centres. The (static) engine performance maps including Brake Specific Fuel Consumption maps, ge (CO2), and maps of speciftc emission of CO, HC and NOX,, serve as the basis for this study. Underlying such an approach are the disparate courses offuel consumption and emission levels in the driving and non-driving modes of the engine. For the study purposes, an adeąuate testing programme should be implemented, using a variable driving cycle [1]. A departure from the homologation cycles applied to this end allows covering, on an engine performance map, the area of engine operation being of interest to us with measuring points. For calculations in operational conditions, the maps of changes of Delta ge, Delta CO2, Delta CO, Delta HC and Delta NOX for nonstationary operating conditions of the engine will be a complement to static engine performance maps. The author has already developed partial maps for the first two parameters. The development of the others requires the implementation of a costly research scheme in cooperation with a leading domestic research centre.

Cytata wydawnicza:: Defays G. 2017. Assessment of the Can Bus Technology Implemented on Modern Agricultural Tractors to Study Fuel Consumption Savings. [in:] Lorencowicz E. (ed.), Uziak J. (ed.), Huyghebaert B. (ed.). Farm Machinery and Processes Management in Sustainable Agriculture, 9th Int. Scient. Symp. ULS Lublin, p. 97-102
Opis:: In developed countries, the mechanized agriculture is highly dependent on fuel. Unfortunately, the heterogeneity and complexity inherent to agricultural process do not help the actors (researchers, counselors, farmers) to improve fuel consumption efficiency in the farms. In order to measure precisely the use of the tractors this study proposes to rely on the embedded CAN bus technology and RTK positioning system implementing modern tractors to record fully characterized data of the engine load. This study demonstrates the feasibility of such proposition by testing specific dataloggers and software in-situ and by decoding signals to data and characterizing them.

Opis:: Problem wyznaczenia sprawności efektywnej silnika samochodowego w dynamicznych warunkach pracy jest kluczowym w obliczaniu całkowitej energochłonności ruchu pojazdu i optymalizacji zużycia paliwa. Dlatego wśród niewielu metod praktycznego rozwiązania tego zagadnienia najbardziej atrakcyjną wydaje się jej odniesienie do znanej sprawności efektywnej silnika dla statycznych warunków pracy z charakterystyki uniwersalnej. Autor w obliczeniach tego problemu wykorzystał metodę bilansu energochłonności ruchu w zmiennym pod względem dynamiki przyspieszania cyklu jezdnym i porównania wyników obliczeń z rzeczywistym zużyciem paliwa. Założono w obliczeniach prostoliniowy wpływ dynamiki przyspieszania prędkości obrotowej silnika na spadek sprawności efektywnej wyznaczonej dla statycznych warunków pracy.
The problem of determining the car engine efficiency in dynamic operating conditions is of great importance while calculating the total consumption of energy when the car is driven. It also enables to define the optimum energy consumption. Up till now only few methods have been used but the one which seems to be quite effective is based on the actual engine efficiency at static operating conditions from universal characteristics. The method of energy consumption balance in a variable driving cycle (the dynamics of acceleration was changeable) was applied and the calculation results were compared to the actual fuel consumption. It has been assumed that there was rectilinear influence of acceleration dynamics of the engine upon the decrease of actual efficiency determined for the static operating conditions.
