POPA 2 1 Technical University of Cluj-Napoca, ROMANIA, popa.marcel@tcm.utcluj.ro 2 Technical University of Cluj-Napoca, ROMANIA, badiu.ioan07@yaho.com Abstract: A piston machine body, which has a reciprocating motion in a cylinder and which is designed to close a space of variable volume of the cylinder, filled with air or a fuel mixture under pressure fluid. The piston is used for converting internal energy into mechanical work on cars engines, or vice versa, generating machines. In the first case the piston is driven by the internal energy, and in the second he acts on air or fluid (compressor, hydraulic motor). Several producers of oil engines use injectors for each the piston in part to facilitate their cooling. The injectors are mounted on the engine block and the oil injected into an opening located in the piston head. Keywords: pistons, engine oil injectors, cooling, heat accumulated, circular holes,edm. 1.INTRODUCTION Usually the piston is coupled to a crank mechanism, which converts the rectilinear motion in a circular motion (the engine) and vice versa (on pump). The piston is used as a constructive element in the implementation of piston pumps, which is similar in principle of operation with the compressor. The pistons are made mostly of cast iron or metal alloy lightweight, heatstable properties.on machines that heat distribution is through the windows, the piston has the function to open or close them.several producers of oil engines use injectors for each the piston in part to facilitate their cooling. The injectors are mounted on the engine block and the oil injected into an opening located in the piston head. Figure 1: The oil Injector the piston Oil injected into the piston head is discharged through circular holes thus eliminating heat in the piston. 98

THE GROUP THE PISTON 100 For a better understanding of the distribution of temperatures on the body of a the piston in an engine design phase, graphic stations is done using finite element analysis. Piston,

Figure 7: The temperatures distribution in the body of the piston C C C C C In conclusion to limit the thermal load of a the piston engine should operate at low engine speeds and loads more ADVANCED TECHNOLOGIES FOR APPLIED TO THE PISTONS THERMAL PROTECTION OF THE PISTON OF THE HEAD ( Federal Mogul Thermoshield). Since 2006 Federal Mogul pistons started marketing Thermoshield, for high power motors. The innovation consists in coating the piston of the head with a ceramic coating to withstand temperatures up to 1093 C with durability compared with conventional pistons The method consists of a special electroless plating to the surface of the piston converted into a complex ceramic high thermal and mechanical resistance. This technology can be applied and fire channel segment, thus avoiding microsudurile between the piston and segment OF STEEL THE PISTONS (Federal Mogul -Monosteel). In 2006, during a ceremony held on April 3rd in Detroit, Federal Mogul company receives PACE Award for innovation, technological advancement and business performance. This award is given to suppliers in the industry that produce, process or offering automobile manufacturers. Figure 9: The piston Monosteel. 101

10 6.CONCLUSIONS The product category piston Monosteel has won. Innovative technologies underlying the piston Monosteel contribute to improved performance of heat resistance, mechanical, abrasive and corrosive, this the piston is used in road transport diesel applications. Federal Mogul engineers developed a friction welding technology, which gave birth to a light steel piston called Monosteel. In addition to increased mechanical strength piston also benefits from oil cooler massive galleries that allow higher thermal regimes. References [34] Ailincai, G.: Studiul metalelor.
