Opis:
The history of hybrid vehicles has started between the 19th and the 20th century because then the first project of a hybrid vehicle was constructed. The first man who manufactured a front hub mounted electric propulsion connected with a generator powered by a spark ignition engine was Ferdinand Porsche. This vehicle was called the Lohner- -Porsche Electromobile. The first mass-produced hybrid vehicle was the first generation Toyota Prius. The model premiere was in 1996 and the production started one year later. The vehicle was equipped with a 1.5 dcm 58 hp spark ignition engine and with the added electric propulsion. It generated 40 mechanical hp. Since 2000, a 72 hp spark ignition engine and a 44 hp electric generator were mounted. Fuel consumption of this model was 5 litres per 100 km. In the early 2000s, 95% hybrid vehicles were the Toyota Prius. The biggest competitor to the Toyota Prius was the Honda Insight. Lexus and Mercedes started manufacturing hybrid vehicles few years later. The most popular car brands that sell hybrid vehicles are Toyota and Lexus from Toyota Motor Corporation. This article describes an example of diagnostic possibilities for the hybrid vehicle system. The construction of vehicle models that use two propulsion systems (spark ignition engine and electric generator) results in the development and increase in control system devices. The measurements were made using various diagnostic devices, e.g. a diagnostic scanner, mustimeter, megohm-meter and oscilloscope. The reading of fault codes is not enough so it is necessary to use a mustimeter or a megohm-meter to examine the signal characteristics, which is presented in this article.

Opis:
Initially, electronic components replaced the mechanical ones to make various systems more reliable. Mechanical control systems, due to the wear of movable parts and imprecise adjustment, were affected by large errors, which are not shown by electronic circuits operating according to constant set-points. Then, a sharp increase in electronisation was associated with the tightening of exhaust gas emission regulations. Progress in some cases is forced by environmental protection, in other ones by market competition. Modern motor vehicles, slow moving vehicles, military vehicles, etc., are the technical systems being constructed using the latest developments in many fields of science, first of all in mechanics and machine engineering, electrical engineering, electronics, information technology, and chemistry. The rapid development of electronics has led to an increase in the number of electronic components in motor vehicles in all systems, starting with an engine, which has been modified first, to comfort and infotainment systems. The paper presents example measurements of sensors and actuators of an engine with Common Rail fuel supply system on the example of Fiat 1.3 JTD MultiJet engine. The measurements were made using various diagnostic instruments, such as a diagnostic tester, a multimeter or an oscilloscope. Sometimes, the reading of error codes with a diagnostic tester itself is not enough and it is necessary to check the signal waveform with an oscilloscope, which has been presented in this paper.
