ATmega8 of AVR chip was used in the automobile pre-heating control system. Automotive pre-heated working principle was analyzed. The system of the pre-heater was designed and the hardware composition of the heating system, the structural features and the role of each module was introduced. It was expounded the process control including the heated air intake phase, to the oil phase, ignition phase and work phase. At last, the advantages and disadvantages of the pre-heater were introduced.

ABSTRACTThe use of single-mode cavities has been recognized as a viable technique for sintering and joining ceramics and for creating microwave plasma for materials processing. It is often reported, however, that tuning these cavities at lower and higher temperatures critically depends on the types of materials being processed, the variation of ε* as a function of temperature, the size and shape of samples, and the overall heating system configuration with and without insulation.In this paper we use the finite-difference time-domain technique to address the performance of the single-mode cavity heating system under a wide variety of heating conditions and system configurations. Specifically, practical issues such as limiting values of sample sizes, the dependence of optimal sample sizes on the complex permittivity of materials under test, the role of sample shape on enhancing uniformity of heating patterns, and various tradeoffs involved in utilizing various cavity modes and/or SiC rods as stimulus for heating large samples are evaluated.

The Role of the Latvian District Heating System in the Development of Sustainable Energy Supply The aim of the study is to determine whether and to what extent it is possible to use excess electricity produced by wind power plants during low demand periods for district heat production by heat pumps. Energy system analysis on an hourly basis is conducted at various capacities of wind power plants. The results show that it is possible to increase the share of renewable energy sources, decrease the use of primary energy sources and CO2 emissions per unit of the produced energy, i.e. heat and electricity, by using the surplus electricity produced by wind power in the heat pumps combined with the heat storage.

The Impact

Abstract The improvements in wind energy infrastructure have been a constant process throughout many decades. There are new advancements in technology that can further contribute towards the Prognostics and Health Management (PHM) in this industry. These advancements are driven by the need to fully explore the impact of uncertainty, quality and quantity of data, physics-based machine learning (PBML), and digital twin (DT). All these aspects need to be taken into consideration to perform an effective PHM of wind energy infrastructure. To address these aspects, four research questions were formulated. What is the role of uncertainty in machine learning (ML) in diagnostics and prognostics? What is the role of data augmentation and quality of data for ML? What is the role of PBML? What is the role of the DT in diagnostics and prognostics? The methodology used was Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA). A total of 143 records, from the last five years, were analyzed. Each of the four questions was answered by discussion of literature, definitions, critical aspects, benefits and challenges, the role of aspect in PHM of wind energy infrastructure systems, and conclusion.
