V-Series Diesel Engine

摘要

The utility model is aimed at improving the specific weight and size characteristics of a diesel engine designed for use in diesel-generator sets of transport and technological means. A 12-cylinder diesel engine is performed with a V-shaped arrangement of rows of cylinders 1.1, 1.2 and a camber angle between them of 60 °. The crankcase 3 is made of cast iron by casting together with a cavity that performs the function of an intake manifold 5 of charge air. To reduce the overall dimensions of the engine, the cavity is located in the central upper part of the crankcase, and the shape of the cavity is performed in accordance with its contour. For the cavity to function as an intake manifold, this cavity is completely blocked by the crankcase 13 of the drive units of the gas distribution mechanism from the side opposite to the charge air supply side. For this, the crankcase of the drive units of the gas distribution mechanism is installed between the crankcase and the flywheel housing 15. For the same purpose, exit windows 6.1–6.12 are made in the cavity for the passage of charge air into individual cylinder heads 2.1–2.12. The charge air from the turbochargers 8.1 8.2 is fed through the air inlet pipes 7.1-7.10 to the charge air coolers 12.1 and 12.2. Then, through the air intake pipes 7.8, 7.9, the charge air enters the pipe 7.10 and the charge air intake manifold, and then through the exit windows to the cylinder heads from the side of the engine collapse. In the design of the intake manifold, technological tides are made under the grooves for fastening the cylinder heads to the crankcase and under the fasteners. After the combustion process, the exhaust gases enter the exhaust manifolds 11.1, 11.2, and then through the exhaust gas pipes 10.1, 10.2 go to the turbine turbines. The crankcase housing of the gas distribution mechanism drive units mounted on the rear end of the crankcase is made of cast iron and is used to protect the gear wheels of the gas distribution mechanism and the high pressure fuel pump drive. Brackets 9.1, 9.2 are attached to the crankcase of the assemblies for installing turbochargers and flywheel housing 15, so that the turbochargers are mounted above the flywheel 14. The flywheel housing is mounted with a flange for fastening starters and motor-driven assemblies to it. 4 ill.
