Significant aspects of the consequences of global warming and some measures that can be undertaken in order to reduce energy consumption and harmful emissions have been presented. The most important actions I this field are related to the renewal of the design of automobile vehicles and their components. A theoretical survey has been carried out in two main areas: invesitigating possibilities of improving the operational characteristics and the design parameters of transmissions and gearboxes, aiming to identify the areas of future dissertation research. A systematization of the reviewed scientific publications has been carried out. Main areas in which additional research can be carried out, related to the specific features of the Bulgarian industry and the state of the available cars in usage, have been identified.

The results of kinematic and force analysis of the new six-link converting mechanism of the sucker rod pumper drive (SRPD) are presented in this paper and the advantages of the alternative design are substantiated. Using a straight-line generating mechanism allows reducing essentially converting mechanism dimensions and metal consumption as compared with traditio nally used SRPD with swinging balancer and crank-based counterweight, first of all, due to eliminating the complicated arc head (so-called «horse-head») of the existing units. However, in order to make sure the working capacities of non-balancer mechanism, kinematic and force characteristics have to be studied. The results of mathematical modeling of the six-link mechanism confirm the qualitative advantages of the straight-line generator. As a result of the study of the rectilinear-guiding mechanism as a transforming mechanism for the drive of sucker rod pumping units, the laws of motion of the links, position, speed and acceleration of all points were determined. To solve the problem of kinematic analysis, the method of closed vector contours was used, which makes it possible to determine the functions of the position of links and analogs of speeds and accelerations. When solving the problem of strength analysis, the equilibrium of each link was considered. As a result of force analysis, jointly solving the equilibrium equations of the links of the six-link hinge-lever mechanism, the reactions of the hinges of the mechanism are determined. A computer model for studying the kinematics and kinetostatics of the converting mechanism of the sucker rod pumping unit drive has been developed

“…Predicting and analyzing the dynamic behavior on polished rod during CBM production is very complex by considering the wide variety of design variables available and the problem in coupling the performance of pumping installation and producing CBM well. For the present practice, many authors have developed approximate computational formulas for the computation of dynamic loadings on polished rod based on the analytic approach of conventional oil/gas fields [3][4][5][6]. And four methods available have generally been used for the operators to predict dynamic loadings on polished rod for the specific pumping installation.…”

-A modern methodology has been proposed for the system design of dynamic behavior in order to provide the accurate pertinent analysis of CoalBed Methane (CBM) pumping installations. Dynamic hanging loads on polished rod can fully reflect the kinematic and dynamic characteristics of CBM pumping installations due to their combined action of the inertial hanging loads with the loads generated by vibration and hydrodynamic friction phenomena. The practical dynamometer cards were determined by computing dynamic hanging loads with the increments of stroke length. The interpretations of results show that the maximum errors of within 2% between the calculated and measured values are obtained with the comparison of calculated hanging loads by American Petroleum Institute (API), Schafer, Gibbs and proposed method. The ratios of inertial and vibration to polished-rod load are relatively high in producing CBM wells and calculated to be 10% and 8%, respectively. And the inertial and vibration hanging load ratios decrease rapidly for two-phase CBM wells. Moreover, the effect of friction loadings on polished rod is more obvious than that of inertial and vibration hanging loads for single-phase gas CBM wells. The total deformations of rod string and tubing are within 15% of polished-rod stroke length in producing CBM wells. And the dynamic loadings enhance the imbalance of hanging loads and improve the power consumption of CBM pumping installations. The total hanging loads on polished rod are variable in a large scale for the pumping prophase and single-phase water CBM wells and the variation range of dynamic hanging loads is much lower for the two-phase and single-phase gas CBM wells.
