“…Analysis was carried out on the effects of changes in structural parameters using the DIESEL-RK program on selected engine operating parameters, such as flame temperature, temperature and pressure of the working medium in the cylinder, and the temperature and chemical composition and speed of the exhaust gas in the exhaust channel [10,13]. Literature searches were also carried out on the most common states of inoperability of functional engine systems [19].…”

The article presents a continuation of research carried out to determine the effect of input parameters (changes in engine structure parameters) on selected output parameters (diagnostic measures), based on quickly changing exhaust gas temperature. A method of determining the simultaneous influence of two input factors (the structure parameter and the engine load) on one output factor was presented, as well as an evaluation of which of the analysed input factors has a stronger influence on the output parameter. The article presents the stages of the experimental research conducted and statistical inference based on the results. Three changing parameters for the structure were reviewed: the active cross-sectional area of the inlet air channel, the injector opening pressure and the compression ratio. Based on the quickly changing temperatures of the exhaust gases, three diagnostic measures were defined and subjected to statistical tests. The following data were averaged over one cycle for a 4-stroke engine operation: the intensity of changes, the specific enthalpy and the peak-to-peak value of the exhaust gas temperature. The results of the two-factor analysis are presented. Conclusions on the analysis are given and a criterion for the selection of a diagnostic measure, depending on the analysed parameter of the structural design of the diesel engine, is proposed. The previous part of the article presented the results of the first stage of the elimination study: the one-factor statistical analysis (randomised complete plan). This paper presents the results of the second stage of the studies: two-factor analysis (block randomised plan), where the significance of the effect of changing the values of the structural parameters on the diagnostic measures were analysed in the background of a variable engine load. The next (third) part will present the results of the calculations and analysis of the interaction coefficient of significance.

“…Severi et al (2015) [32] asserted that 20% displacement volume reduction besides providing right-size engine maximum power of studied GDI engine is achievable via 11% piston bore reduction and using both engine boosting and spark advancing, in a numerical investigation. A light duty downsized diesel engine, called z-engine, was developed utilizing homogenous charge compression ignition (HCCI) mode in high load operation by Kuleshov et al [33] and it is asserted that less NOx emission was produced in this way. The concept of designing a boosted uni-flow scavenged direct injection gasoline engine to achieve more than 50% downsizing is presented by Ma and Zhao [34] for a two stroke engine.…”

Engine downsizing is a promising method to reduce emissions and fuel consumption of internal combustion engines. The main concept is reducing engine displacement volume keeping needed output characteristics unchanged. The issue became one of the most filed of interest in recent years after the International Energy Agency defined a target of 50 % reduction in global average emissions by the year 2030. In this review paper, different aspects of researchers’ efforts on engine downsizing are configured and due to overlaps, categorized into five main areas. Each category is discussed thoroughly and recent works are pointed. The global attention into these categories, countries involved and the trend changed in recent four years are presented in details.
