Opis:
Current engine technology for on-road vehicles allows us to meet the existing and planned future standards for emission. Because combustion engines, especially self-igniting are being used for very different purposes like: road transport, rail-way transport, shipping, industry, military and agriculture, these engines work in different and often difficult conditions. A very significant group of vehicles used for the most difficult of the a forementioned areas ofuse are "Off-Road" vehicles. For those vehicles we also use rigorous regulations to govern dangerous chemical emissions such as Tier, Bin and Californian LEV. In those types of vehicles the fuel powered systems very often use mechanically controlled diesel injection pump. These pumps are characterized by high tolerance to the quality and type ofpetrol as well as reliability, which is very important especially in "off-road" vehicles. At work a conception was described of system of powering the engine diesel which will let for reaching of future emission exhaust quality standards. In the paper only initial outline of the idea of the injection 's system for „off-road" vehicles, is introduced. This system needs follow-on in the field both interactions with the EGR valve, with the injection 's system as well as in the matter of interaction with ECU of the injection 's system.

Opis:
The operation of diesel engine is closely connected with controlling the process of injecting the fuel into the cylinder. It influences proper combustion process, which translates directly into irregular engine operation resulting in dumping and noise. It is related to improper control of fuel injection which is connected with improper completion of expected control strategy that can be a result of defective injection system. Irregular engine operation can also be caused by total lack of initiated combustion process in specific cylinder of the engine or in several cylinders, described as misfire, or ca be a result of differences in combustion process in individual operation cycles / engine cylinders. The effect is an engine working irregularly (there is instability of rotational speed) and emitting increased amount of pollutants. As a consequence the secondary fuel purification systems located in the exhaust system can be damaged. Therefore, it is required to choose the fuel injection control parameters in a way that enables detecting and correcting the process of fuel injection in order to minimize effects resulting from improper process of fuel combustion in individual cylinders or even lack thereof. It is useful to suggest diagnostic parameter that can be used to detect engine faultiness or elements of the accessories such as e.g. injection system. Ability to apply such control and correction of injection dose is provided by modified mechatronic in-line injection pump. The study shows results of researches on modified injection system with mechatronic in-line injection pump that enables identification of misfire and preventing irregular operation of diesel engine.
