Control to driveline units is no exception. Application of clutch with the system of compensation of wear of friction overlays can not only enhance comfort, due to maintaining a stable effort on the pedal, but also improve the performance of the clutch. In the article a comparative analysis of the traditional design of the pneumohydraulic booster (PHB) and the design, which has a mechanism for compensating the wear of friction plate of clutches. As a compensator for the wear of friction plate of clutches, a telescopic rod with a closed cavity is used, which is filled the brake fluid through a reverse valve. With the wear of friction clutches, the fluid has the ability to slowly flow out of the closed cavity of the rod due to the leakage of the reverse valve. A positive feature is the ability to implement the proposed design within the framework of the traditional design of the pneumatic booster without changing the basic parts. As a result of the application of the proposed designs, it is expected to obtain such positive qualities as reducing the mass and material capacity of the product, maintaining high clutch performance regardless of the degree of wear of friction plates, reducing air consumption in operation (and, consequently, reducing fuel consumption), reducing the overall dimensions of the PHB. In order to confirm the new qualities, the consumption of air and fuel during the operation of both design of PHB on the typical urban route in the route bus is calculated. When calculating, the clutch exclusions taken into account are required during acceleration after each stop and traffic light. A reference to the investigation of the speed of the clutch control mechanism with new and worn friction plate of clutch is given. The properties of the proposed PHB design with the mechanism of compensation of the wear of the friction plate of the clutch are analyzed and the effect is shown not only in the manufacture of this design, but also from the application of this design in operation, which is expressed in fuel economy","PeriodicalId":121866,"journal":{"name":"Automobile transport","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127906772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis of the performed exergy calculational and experimental research on the evaluation of energy loss in the intake system of the engine for current modes of its operation has been presented. The sample of a piston pneumatic engine for a combined automobile power unit created at the ICE Department of KhNAHU requires further improving and developing especially such components and systems as those connected to the burn process. A compressed air intake system is one of them. Compressed air is not only some working fluid for a pneumatic engine but the energy source for its intake system. The energy loss factor like reliability and durability is referred to the performance and efficiency factors. The object of the study is a pneumatic engine created by converting a gasoline four-cylinder four-stroke ICE at the ICE Department of KhNAHU. The experimental research was carried out by laboratory engine test rigs of the pneumatic engine with speed characterization provided that two thermodynamic parameters of compressed air at the intake were kept constant for each characteristic: pressure p s = idem and temperature Т s = 293 K. In each test mode all external parameters of the pneumatic engine were recorded and indicator diagrams of the first cylinder were taken. Each speed characteristic consisted of 6–8 modes p s = idem and Т s = 293 К = idem with changing the rotational rate of the crankshaft n, rpm, from minimally stable (about n=200 rpm) to maximum possible n = 1000 ± 50 rpm It should be noted that there is an operating fluid pressure drop in the intake system chamber due to available inconvertibilities: throttling in the test port, hydraulic loss along the intake port as a result of fluid friction, swirls and other gas-dynamic phenomena.
