Abstract

The utility model is aimed at reducing the overall dimensions of a diesel engine with an in-line arrangement of cylinders along the length. The technical result is achieved due to the fact that the snail (3) of the water pump (2), the flange (4) for installing the fuel pump (5) and the flange (6) for installing the pneumatic compressor (7), and the guitar ( 8) gears for driving the main and auxiliary units has one level.

Description

The utility model relates to the field of mechanical engineering, namely to engine building, and is intended for use, in particular, in vehicles.

In the field of vehicles, the problem of the size of diesel engines is quite acute due to the limited overall dimensions of the engine compartment. Therefore, in diesel engineering, an important role is played by technical solutions to reduce the overall dimensions of engines.

The prior art in-line diesel engines of various layouts, which are the drive of various devices and mechanisms.

Known in-line internal combustion engine (hereinafter - ICE) with a turbocharger containing an intake manifold located on the right side of the engine (when viewed from the opposite side of the power take-off), and a turbocharger mounted on the left side of the engine. The intake manifold is connected to the cylinder inlets and is connected to the turbocharger nozzle (http://dizelmmz.ru/d/797360/d/dvigateli_d260.1_d260.2_d 260.4_d260.7_d260.9_d260.14.pdf).

The disadvantages of the known engine are significant overall dimensions.

Also known is a six-cylinder inline diesel engine with an in-line arrangement of cylinders, comprising a crankcase, a crankshaft having a torsional vibration damper on the front nose and an oil pump drive gear, water pumps, a fluid coupling, a camshaft and a fuel pump, and an outer half coupling on the rear , speed regulator, lubrication system with oil pan, oil pump, pressure reducing valve, oil receiver, oil filter, full-flow oil filter, oil pumping unit, oil cooler (oil-water cooler) and oil channels, fuel supply system with high-pressure fuel pump, fuel pump, fuel filter, nozzles, low and high pressure pipelines. The known engine contains a cooling system having centrifugal water pumps, a fluid coupling, water temperature controllers and water channels, a turbocharging system with one turbocharger, a charge air cooling device (hereinafter referred to as ONV), an exhaust manifold, inlet pipes and manifolds (http: // vdm-plant. com / docs / RA_SA_20_25.pdf).

The disadvantages of the known engine are significant overall dimensions in length and width.

The closest technical solution adopted for the prototype is a diesel engine with an in-line arrangement of cylinders mounted on a cast crankcase containing a gas turbine supercharger, including a turbocharger installed in the rear of the engine, an intake manifold, air inlets located above the level of the crankcase, exhaust manifold, charge air cooling device, characterized in that it further comprises a charge air cooling device, the charge air intake manifold is made in the form of a cavity in the cast crankcase casting, in its upper lateral part, and the cavity, in shape repeating the circuit of the crankcase, contains windows for the passage of charge air into the cylinder heads and technological plugs from the front and rear ends of the crankcase, and in the upper lateral part of the crankcase, reference tides are made for installing charge air cooling devices, while the reference tides are the through cavities are pressed, which are completely blocked from above by cooling devices for charge air, and from below are made passing into the cavity of the crankcase (see Utility Model RU 186499, published January 22, 2019).

A disadvantage of the known diesel internal combustion engine is the significant overall dimensions along the length.

The task was to reduce the overall dimensions of the engine with an in-line arrangement of cylinders along the length to ensure the possibility of use on a vehicle.

The technical result is achieved by the fact that in an engine with an in-line arrangement of cylinders mounted on a cast crankcase containing a cooling system with a water pump and a drive of main and auxiliary units, in order to optimize the length of the engine, a water pump scroll and a flange are integrated to drive the fuel pump, while the guitar gears for driving the main and auxiliary units has one level.

The combination of distinctive features, namely, that a water pump coil and a flange for driving the fuel pump are integrated in the crankcase, while the guitar of the gears for driving the main and auxiliary units has one level that allows to reduce the length of the internal combustion engine, which in turn allows you to set this engine, in particular in the engine compartment of a vehicle.

The applicant does not know an engine with in-line cylinders with the specified set of essential features and the claimed set of essential features does not follow explicitly from the current level of technology, which suggests the conformity of the claimed technical solution to the condition of patentability “novelty”.

The inventive utility model is illustrated by drawings:

FIG. 2 Engine with in-line cylinders, left side view;

FIG. 3 engine block crankcase;

FIG. 4 Guitar gears in-line engine.

An engine with an in-line arrangement of cylinders contains a crankcase 1, a crankshaft, cylinder heads with a gas distribution mechanism, intake and exhaust pipes, a turbocharging system, a cooling system with a water pump 2, a snail 3 of a water pump, a flange 4 for installing a fuel pump drive 5, a flange 6 for installing a pneumatic compressor 7, a fuel supply system, a lubrication system and a guitar 8 gears for driving the main and auxiliary units.

An engine with an in-line arrangement of cylinders works as follows: when the crankshaft rotates, the torque is transmitted to the shaft of the water pump, the shaft of the pneumatic compressor and the shaft of the fuel pump through a single-level guitar of 8 gears.

In order to optimize the length of the block crankcase 1, a water pump snail 3 and flanges 4 and 6 are integrated into the crankcase casting to install the fuel pump drive 5 and pneumatic compressor 7, and the guitar 8 gears for driving the main and auxiliary units has one level.

An engine with in-line cylinders was manufactured under industrial conditions and was tested as part of a car, which allows us to consider the claimed utility model meeting the patentability criterion of “industrial applicability”.
