Landfill gas recovery and utilisation is a solution which reduces the adverse environmental impact of landfill. Combined heat power (CHP) generation improves energy balance facility enables optimal management generated from renewable source. This article aims to analyse operation CHP unit in two aspects, that is, terms efficiency operational availability. Energy ratios were calculated analysis was based on Weibull distribution order assess unit’s reliability minimise costs maximise...

The description attempt of the system person-vehicle-environment as an element person-technical object-environment has been made. In analysis reliability machine exploiter – a car driver taken into account. It pointed out that technical operators (in this case drivers) have to be considered important in structure these systems. operational and biological characteristic human being operator carried out. necessity for conducting different psychological tests assessment quality each indicated.

The study characterizes the basic distributions of damages in elements included mechatronic devices: exponential, Weibull, normal, log-normal distributions. It considers some special cases, when suitability times for system have above four distributions, and device's is created by three a serial structure various types time elements' suitability. order not important. final section this work presents case, structure. Suitability these different

National Road Safety Program 2013-2020 assumes to reduce fatalities by half and seriously injured 40% from 2010 2020. It means that no more than 2,000 people per year should die on Polish roads 6,900 suffer serious injuries in traffic accidents. The experience of other European Union countries with improving road safety gives hope these goals are still realistic, but there is a need intensify the activities carried out this area. In Poland, institutions taking part process safety: state...

For the safety of supply, diesel generator (DG) sets are used in various stand-alone power systems using variable-speed generators. The hybrid grid system presented this article, with a wind and generator, but also ship’s network, serves as an example. To ensure exploitation, parallel operation two supplies is required. In required symmetrical active load (regardless size), internal combustion engine DG set often underloaded. This leads to deterioration its technical properties and,...

The article concerns the possibility of using a fuel pretreatment system in modern compression ignition CI engines, main task which is reduction toxic emissions form exhaust gases. This consists catalytic reactor used common rail (CR), and modified atomizer into spiral‒elliptical channels covered with material. In presented here, platinum was catalyst. catalyst’s to cause dehydrogenation reaction paraffin hydrocarbons contained create an olefin form, release free hydrogen molecule....

The International Maritime Organization are introducing more and stringent requirements concerning increasing ships’ energy efficiency. They becoming a huge challenge for design engineers. This article proposes method to increase the efficiency of mechatronic drive systems in ship via use highly efficient electric permanent magnet synchronous motors (PMSMs). An innovative control strategy is suggested. It based on modification classic PMSM ensuring optimization through reduction reactive...

The research objective of this project is to assess the possibility making and applying annular channels on a non-operating element spraying nozzle needle with catalytic additive without it. purpose structural modifications being made improve process fuel-air mixture combustion by compression ignition engine. task fuel atomisation in chamber increase turbulent phenomena injector nozzle. A material, form platinum, applied induce dehydrogenation hydrocarbons paraffin group comprised olefin...

The article describes the high pressure fuel pump CP1H Common Rail system and injectors which worked on bad quality. It was presented how can injection diagnose. Research objects were dismantled for spare parts checked under microscope. Paper discusses construction mechanism of action researched injectors. During researches has been crucial elements. described areas where are produced metal fillings in it influences discussed methods prevents them. In addition, influence state power supply...

Abstract In the article are characterized two network methods (critical path method - CPM and program evaluation review technique PERT). On example of an international furniture company’s product, it presented exemplification to transport cargos (furniture elements). Moreover, study showed diagrams for transportation from individual components’ producers final destination showroom. Calculations were based on elements via small commercial vehicles.

Some aspects of marine electric power plants load registration and identification have been presented. Methods operating data collecting about plant loads shown based on an example three vessels - a chemical tanker, container ship tanker. Power these described. Examples collected were Range research has characterized, which presented in the paper results are part of.

In marine systems, autonomous power generation unit sets play an important (main) function, and the Automatic Voltage Regulator (AVR) is a part of excitation system synchronous generator that difficult to test, repair, adjust by Electro Technical Officer (ETO) automation services. Typically, testing AVR on ships carried out installed AVRs in operating generator, which creates significant challenges. Under conditions, achieving various states practically impossible. this article, authors...

This work presents the general characteristics of port system.It defines sets and functions describing structure port.Moreover, it characterizes foundations massive handling theory.It provides basic literature information about selected processes models theory.On example a transportation company serving loading on ships in Szczecin, shows method.The material onto was sodium water glass.There are observation results operation times comprising data available to determine parameters...
