Opis:
On the present there is very intensively emphasized the environmental protection, which is also connected with reduction of emissions produced by the vehicles. The actual European emission standard EURO 6 will be replaced very soon with the new and even stricter standard EURO 7. There is a well-known fact that the new regulations are demanding with regard to the NOX emissions. However, there is at disposal a suitable technical solution, namely in the form of an innovative engine technology, which is called the HCCI. A principle of this technology consists in a self-ignition of the homogenous air-fuel mixture using the compression process. Combustion of the mixture is performed in the whole compression volume without a spark ignition, whereby the NOX emission level is almost negligible. However, this technology is also characterised by several serious problems, for example there is occurring a complication concerning control of the self-ignition phenomenon. The presented article introduces an original diagnostic system, which enables to control the whole self-ignition system and in this way to ensure a reliable operation of the HCCI engine. This system is patented now as well as it was tested in an experimental vehicle built for the international competition “shell eco marathon”.

Opis:
The engine output characteristic offers very important information during the real application of the HCCI technology. This kind of combustion process significantly influences the wearing degree of the main engine components or even the engine damage. The principle of the HCCI combustion is basically beneficial, however, it can also be destructive. Described in this article are measurements of the engine output characteristics in the case of an experimental piston combustion engine. These measurements were performed by means of a data recording system, whereby the detonation combustion was evaluated using a quantitative method. The real values of atmospheric conditions and fuel mixture composition were added to the measured values. The resulting values were visually compared with a degree of the engine piston damage caused by the detonations. The final result is a limit value, which represents a maximal number of the detonation units that are permissible in order to ensure reliable operation of the HCCI engine.

Opis:
Evaluation of the measured data, which are obtained from testing of the HCCI engine prototype, is a complex process taking into consideration questions of the vibration diagnostics. The complexity of this procedure is caused due to a necessity to evaluate a large amount of the various data. One of the solution possibilities is application of a multidimensional statistical model within the evaluation process in order to obtain more accurate information about the actual operational condition concerning the analysed engine.

Opis:
The evaluation process of measured data in terms of vibration diagnosis is problematic for timeline constructors. The complexity of such an evaluation is compounded by the fact that it is a process involving a large amount of disparate measurement data. One of the most effective analytical approaches when dealing with large amounts of data is to engage in a process using multidimensional statistical methods, which can provide a picture of the current status of the flexibility of the machinery. The more methods that are used, the more precise the statistical analysis of measurement data, making it possible to obtain a better picture of the current condition of the machinery.
