Impact of an external, so called box, module on gases composition of the ROVER 2.0 CDTI engine

Environmental impact of the motor vehicle has been felt in every stage of the motor vehicle operation. In the initial phase of the operation, when the vehicle is new, the amount of pollutants getting into the environment is less than at the end of its life, before the scrapping. This is connected with wearing the engine during its operation. However, the need for better performance through the chiptuning or the Box type devices are quite common nowadays, but the impact on the environment may not exceed the permitted emission limits. The article describes the external, so-called Box, module and its impact on the change of the injector opening time, and also on the change of the ROVER 2.0 CDTi engine power and torque. The simplicity of this device lies in the fact that such a modification can be made by everyone who follows the installation instructions. It is not necessary to conduct the program reading, like in the case of a program exchange in the EEPROM or programming via the diagnostic connector EOBD. The external module (box) is connected between the ECU and the Common Rail injectors. Thus, the control program does not change, but the injector opening time is adequately increased

Impact of an external, so called box, module on power and torque of the fiat 1.3 JTD motor

With the emergence of vehicles equipped with fuel injection systems with EDC electronic control system (Electronic Diesel Control) on the market, there appeared opportunity to make changes within the factory program of engine control management. This enables precise and differentiated shaping of the course of combustion. With the gradual development of the EDC different methods of intervention in the engine control program appeared, including exchange of the program in the EEPROM, connecting the external modules, so called Boxes, and programming via the EOBD diagnostic connector (European On Board Diagnosis). The article presents the external module, so-called Box and its impact on the variation in pressure in the Common Rail high pressure cell, and also on the power change and torque of the Fiat 1.3 JTD MultiJet engine. It is both the simplest and least effective method of increasing vehicle performance. Its simplicity lies in the fact that such a modification may be made by anyone who follows the installation instructions. There is no need to carry out program reading like in the event of program exchange in the EEPROM or programming by the EOBD diagnostic connector. The external module (box) is connected between the EDC and the fuel pressure sensor in the Common Rail cell. Thus, the control program does not change, but it is "cheated" by the module forcing from the EDC other values of signals controlling the actuators

Zastosowanie interpolacji przedziałowej do opisu charakterystyk zewnętrznych silnika o zapłonie samoczynnym

In this paper is presented a calculation method based on Lagrange's interpolation formula which has been used for mathematical description of the performance characteristics of a compression-ignition engine of the 359 type of the Polish production. Its application allows simplification of experimental tests through preservation of a minimum number of measuring points and estimation of other data analytically. In order to minimise the interpolation error occurring with polynomials of high degrees and constant node distances, the characteristics were approximated by spline functions with both solutions being shown comparatively in the graphical form. As calculation examples, the curves of specific fuel consumption and infrared radiation absorption coefficient were chosen, which had been obtained during examinations on engine test bench for a drive unit fuelled with four types of fuel. In addition, results of the experiment required for their determination were tabulated. The presented method may be used in further tests of a given engine as well as on other experimental benches, aiding long-lasting and expensive optimisation of operating parameters when using fuels of plant origin. Description of any performance characteristics by means of interval interpolation is convenient from the practical side and does not cause greater calculation problems since polynomials of low degrees are being used in the procedure.W artykule przedstawiono metodykę obliczeniową bazującą na interpolacji wielomianowej Lagrange'a, którą wykorzystano do matematycznego opisu charakterystyk zewnętrznych silnika o zapłonie samoczynnym produkcji polskiej typu 359. Jej zastosowanie pozwala na uproszczenie badań doświadczalnych poprzez zachowanie minimalnej ilości punktów pomiarowych i oszacowanie pozostałych danych w sposób analityczny. W celu zminimalizowania błędu interpolacji występującego przy wielomianach wysokich stopni i stałych odległościach węzłów, charakterystyki przybliżano funkcjami sklejanymi, przy czym oba rozwiązania pokazano porównawczo w formie graficznej. Jako przykłady obliczeniowe wybrano krzywe jednostkowego zużycia paliwa i współczynnika absorpcji promieniowania podczerwonego, które uzyskano w badaniach na hamowni silnikowej dla jednostki zasilanej czterema rodzajami paliw. Wyniki eksperymentu wymagane do ich wyznaczenia dodatkowo stabelaryzowano. Prezentowana metodyka może być wykorzystana w dalszych badaniach danego silnika, jak również na innych stanowiskach doświadczalnych, wspomagając długotrwałą i kosztowną optymalizację parametrów roboczych przy stosowaniu paliw pochodzenia roślinnego. Opisanie dowolnych charakterystyk zewnętrznych za pomocą interpolacji przedziałowej jest wygodne od strony praktycznej i nie przysparza większych trudności obliczeniowych, gdyż w procedurze wykorzystuje się wielomiany niskich stopni

High voltage batteries diagnostic

Hybrid vehicles history begins between XIX and XX century because then has been constructed first hybrid vehicle project. The first men who produced electric propulsion mounted in front hubs connected with generator powered by spark ignition engine was Ferdynand Porsche. Vehicle was called Lohner – Porsche Electromobile. The first en masse produced hybrid vehicle was the first generation Toyota Prius. These model premiere was in 1996, and production started one year later. Vehicle was equipped in 1,5 dcm 58 hp spark ignition engine with added electric propulsion generated 40 mechanical hp. There has been mounting 72 hp spark ignition engine and 44 hp electric generator since 2000. Fuel consumption of these model was 5 liter on 100 km. Beginning XXI century 95% hybrid vehicles were Toyota Prius. The biggest competitor of Toyota Prius was Honda Insight. Lexus and Mercedes started producing hybrid vehicles few years later. The most popular brands selling hybrid vehicles are Toyota and Lexus – Toyota Motor Corporation. Article describes high voltage battery example diagnostic possibilities in a hybrid or electric vehicle. Constructing vehicle models using two propulsion systems (spark ignition engine and electric generator) cause development and increase control system devices. The measurements has been made by using various diagnostic devices for example: diagnostic scanner mega macs 66, high voltage battery tester. Reading faults code is not enough so it is necessary to use data list what describes this article
