The expediency of converting the transport diesel engines in operation into gas internal combustion engines with spark ignition for operation on liquefied petroleum gas has been substantiated. It is shown that the use of liquefied petroleum gas instead of diesel fuel can reduce the operating costs of vehicles. Multifunctional electronic microprocessor control systems based on Avenir Gaz 37 level “A” and Avenir Gaz 37 level “B” electronic control units have been developed. It is shown that an electronic microprocessor control system with an Avenir Gaz 37 electronic control unit of level "A" allows converting diesel engines into gas internal combustion engines with LPG supply through a gas-air mixer into the intake manifold. The test results showed the high energy and efficient performance of the gas internal combustion engine. The second electronic microprocessor control system with an electronic control unit Avenir Gaz 37 of level "B" allows converting diesel engines into gas internal combustion engines with LPG injection through an accumulative power supply subsystem and multipoint injection of liquefied petroleum gas (Common Rail type) in combination with the use of a contactless electronic subsystem ignition with a movable voltage distributor and a cylinder filling control subsystem with a charge of the working mixture. At the same time, Avenir Gaz 37 "B" ECU with a loaded B1 level software module provides group injection of LPG into the intake manifold and sequential injection with a B2 level software module. The principle of operation of each of the three subsystems, which the D-240-LPG-"B" gas engine is equipped with, is described. The tests carried out on the D-240-LPG-"B" gas engine with the Avenir Gaz 37 "B" control unit confirmed its operability.

The paper highlights the main possibilities available when studying how the vehicles engine operate using algorithms specific to the multivariate statistics. A particular example of studying the engines behavior is represented by the diagnosis activity performed onto the vehicle, an activity that a special attention is being paid to throughout the paper. To this purpose, during the tests we have intentionally caused certain malfunctions to the engine. Circuit breakdowns were intentionally caused on various electric circuits that connect sensors and actuators to ECU. Fitting modern vehicles with electronic control systems offers the possibility for computerized approach of various maintenance operations onto its mechatronic components (sensors, actuators). These components are part of those electronic systems. Such an approach includes onboard simulation of various malfunctions that may occur during normal operation of vehicles. The procedure which is currently presented in the paper herein is about generating controlled malfunctions, using the sensors connector, a signal that is specifically varied towards the electronic control unit (ECU). Thus the ECU will interpret that the system that it is managing indicates a vehicle malfunction. .

Lithium-ion batteries are facing difficulties in an aspect of protection towards battery thermal safety issues which leads to performance degradation or thermal runaway. To negate these issues an effective battery thermal management system is absolute pre-requisite to safeguard the lithium-ion batteries. In this context to support the future endeavours and to improvise battery thermal management system (BTMS) design and its operation the article reveals on three aspects through the analysis of scientific literatures. First, this paper collates the present research progress and status of various battery management strategies employed to lithium-ion batteries. Further, to promote stable and efficient BTMS operation as an initiation the extensive attention is paid towards roles of BTMS electronic control unit and also presented the essential functionality need to consider for designing best BTMS control strategy. Finally, elucidates the various unconventional assessment tools can be employed to recognize the suitable thermal management technique and also for establish optimum BTMS operation based on requirements. From the experience of this article additionally delivers some of the research gaps identified and the essential areas need to focus for the development of superior lithium-ion BTMS technology. All the contents reveal in this article will hopefully assist to the design commercially suitable effective BTMS technology especially for electro-mobility application.

Compression Ignition Engines

In this study, it was aimed to operate today’s compression ignition engines easily in dual-fuel mode with a developed electronic control unit. Especially, diesel engines with mechanical fuel system can be easily converted to common-rail fuel system with a developed electronic control unit. Also, with this developed electronic control unit, old technology compression ignition engines can be turned into dual-fuel mode easily. Thus, thanks to the flexibility of engine maps to be loaded into the electronic control unit, diesel engines can conveniently be operated with alternative gas fuels and diesel dual fuel. In particular, hydrogen, an alternative, environmentally friendly, and clean gas fuel, can easily be used with diesel engines by pilot spraying. Software and hardware development of electronic control unit are made, in order to operate a diesel engine with diesel+hydrogen dual fuel. Finally, developed electronic control unit was reviewed on 1500 r/min stable engine speed on different hydrogen energy rates (0%, 15%, 30%, and 45% hydrogen) according to thermic efficiency and emissions (CO, total unburned hydrocarbons, NOx, and smoke), and apart from NOx emissions, a significant improvement has been obtained. There was no increased NOx emission on 15% hydrogen working condition; however, on 45% hydrogen working condition, a dramatic increase arose.
