The environment under which a cylinder-head gasket has to function is reviewed and a typical cylinder head to cylinder block assembly is considered, outlining the temperature variations in the inlet and exhaust ports. Curves showing head-face to block-face movement for varying engine speeds and coolant temperatures are reviewed with power units running at accelerated gasket destruction test conditions. Comparisons are made between cast-iron block and aluminium head and cast-iron head and block for both petrol and diesel engines.

Blanking Process

Press tool is a press tool used to cut or form a thin plate into the desired shape with a pressing or press machine. This press tool is designed to be able to produce goods in bulk with a relatively short processing time without reducing the quality of the product, so that work efficiency can be improved and can reduce production costs. The design of the press tool for making cylinder head gaskets (3XA - E 1181 - 00) is a Yamaha F1ZR motor with a thickness of 0.5 mm made from ST37 through two processes, namely the embossing process, besides forming, the punch embossing also functions as a stripper. stock), followed by the cutting tool (piercing and blanking) process. Judging from the type of construction, this press tool belongs to the type of compound tool. In the process of making construction products this type has two workmanship functions but in one step work. The force that occurs is the sum of the cutting force (F _p = Us. R_m). The punch center calculation is useful for knowing the center of emphasis. This component is a gas leak retaining plate on the engine cylinder located between the cylinder block and cylinder head.

Negative Form

This paper discusses various methods for form machining of cylinder bores. One alternative is to use so-called torque plates. Torque plates are deformation elements with identical or similar deformation properties as the cylinder head together with the cylinder head gasket. With this deformation element, the cylinder block is clamped using the cylinder head bolts during the honing operation. Various designs of torque plates are presented here — torque plates which are already being used for serial production as well as newly developed, production optimised designs. As an alternative to the use of a torque plate, the kinematics of the honing procedure can be controlled. In this form honing method, not only static deformations but also dynamic and thermal deformations can be taken into account while producing the negative form.

The article describes the characteristics of thermal loading of the cylinder covers of transport diesel engines during their conversion to marine diesels. The engines of the CHN14/14 type produced by the Yaroslavl Motor Plant are proposed as promising for use in marine power plants. A special feature of the engine design is the individual four-valve cylinder heads, which have a complex geometric shape. The conversion of automobile engines, the cylinder heads of which were made of aluminum alloys, to marine ones is accompanied by an increase in the degree of their acceleration. The cylinder heads in operation experience significant thermal and mechanical loads, which causes the need for increased requirements for the materials of the cylinder heads. The rational choice of the cylinder head material is one of the most important tasks to be solved when upgrading and boosting engines. Experience in the operation of marine diesel engines shows that in order to ensure the required reliability under prolonged exposure to elevated temperatures due to forcing, it is necessary to choose cast iron as a structural material. A three-dimensional model of the cylinder head is developed. When performing the calculations, the boundary conditions are justified, taking into account the local nature of the distribution of thermal and mechanical effects on the diesel cylinder head. As a result of numerical modeling, the stress-strain states of cylinder heads made of high-strength cast iron, ductile iron and cast iron with vermicular graphite are determined and analyzed. There has been proved the preference for using cast irons with vermicular graphite, which have satisfactory casting and physical and mechanical properties. The advantages of using cast iron with vermicular graphite include a decrease in the temperature of the cylinder head in the area of the inter-valve bridge. The possibility of increasing the engine power from 330 to 560 kW when replacing aluminum alloys with cast iron with vermicular graphite for the manufacture of cylinder heads is proved.
