Marine Diesel CHRN

Diesel engines consume fuel 221-226 g / (kWh) and lubricating oil 3,3-4 g / (kWh). All modifications to diesel 6CHRN 36/45 automated to the extent of the second degree according to gost 14228-80, equipped with a pneumatic system, dam, and have basically the same design. Block-frame diesel cast iron and to reduce the overall level of vibration engine attached to the ship's foundation in the shock absorbers. Vertical cylinder block is connected to the block-frame with anchor links. In the nest seven transverse frame mounted Crankshaft bearings. Liners interchangeable bearings of steel reinforced tape. In diesel engines the first releases of steel liners, armored babbit B83. One of the bearings (closest to the flywheel) installation.

Cranks crankshaft are located relative to each other at an angle of 120 . On one of the cheeks of each crank counterweights are installed, unloading indigenous bearings of the centrifugal forces of inertia. Go to the front end of the shaft torsional vibration damper is attached. Cast iron cylinder block with a sleeve is divided into six sections. At the bottom of the unit is installed the camshaft.

The rotation of the crankshaft is transmitted to the terminal using the gears. On the camshaft is fixed, two sets of washers fist intake, exhaust valves and fuel pumps. Valve lever to action bars. Cylinder cover individual cast-iron attached to the block of pins. In the lid there is cold start, intake and safety valve and thermocouple. Pressurization of a gas turbine engine. Turbocharger consists of a single-stage axial turbine and a single-stage centrifugal compressor. Intercooler and exhaust manifolds on the same side of the block. Uncooled exhaust manifolds two, each of them is connected to three cylinders: collectors are in the insulating casing. Cast-iron pistons are cooled by oil. Cranks with neotemnoy lower head and stem of I-section are connected to the floating piston fingers. Cover the bottom heads rods with inserts from steel reinforced belts are attached to four rods crankshaft bolts. Diesel fuel system is equipped to work on the engine and diesel fuel. The system motor fuel are included: fuel pump, electric heater and separator. High pressure pump single-section spool type with the end of regulation of fuel. Sprayers cooled engine with a spring locking needle and a multi spray jets. Fuel system with booster gear pump, strainer coarse and fine filter 2TF5. speed controller crankshaft indirect action with the security and compensation piston (see photo diesel) lubrication system diesel engine combined with a "dry" sump. It consists of two gear pumps – Siphoning and delivery, filters, centrifuges, and two tubular cooler with temperature. Countdown pumping diesel oil by means of two electric drive pumps. Cooling system is closed with two centrifugal pumps and tube cooler. Given the water temperature is maintained thermostat. Compressed air to start the engine get from stand-alone compressor. Reversing system pneumohydraulic. Diesel has the drive and manual reverse.
