The Famous Soviet bulldozers T-130 and T-170 and crawler tractor Russian-made B-10 was not half so popular and effective, if not installed in their design of engine D-160.

engine d device 160

This diesel powerplant ahead of his age, and already more than 30 years, is an integral component of some of the most powerful bulldozers. Simplicity, reliability, and performance – all of which is embodied the motor due to its efficient design.

The cornerstone

The Base engine is the engine block coupled with the crank mechanism. The cylinder block is a monolithic cast-iron structure with inserted steel liners. It partitions, along with the front and rear wall serve as a support for the camshaft and crankshaft, and also for the cushion of the decompressor.

To control the status of indigenous and connecting rod bearings in the right wall there are inspection hatches. Here there are hatches for fastening the pushers. Bottom engine D-160 is closed sump with two drain holes. The top is a cylinder head, common on two cylinders.

Patiparn forged crankshaft made of steel, has counterweights and channels connecting rod journals than is provided by centrifugal purification of oil. The shaft flange is fixed to the flywheel with the ring gear. The crown has straight teeth for motors with electric start, and skew for starting the engine.

The Piston is made of aluminum alloy, the combustion chamber is in the bottom. The connecting rods are manufactured by hot forging of steel.

Design features

For damping vibrations produced by the engine D-160 when working with nominal speed of 1250 rpm./min., installed a balancing mechanism. It is placed on the bottom plane of the block and hidden by the sump. Lubrication of the bearings of this mechanism is centralized, but the teeth of the wheels are lubricated by an oil mist which is formed in the internal chamber space of the engine.

Another structural feature is the presence of the decompression mechanism. It opens the intake valves in the cylinder head during the engine start control, or during an emergency stop. Through his work the crankshaft does not meet with resistance and moves freely. Valves are opened by the rod of the decompressor that affect them by turning the roller mechanism.

Cooling System

On the engine D-160 is a closed liquid cooling system with forced circulation of coolant – water or antifreeze. It is provided by a centrifugal pump with mechanical seal. Radiator presents a tubular design with air-steam valve and cooling plates.

For regulating the engine temperature meets the thermostatic valve. In the heated coolant to 70OWith one of them triggered, overrides the small circuit and causes liquid to circulate through the radiator. Thanks to this process more efficient and rapid cooling of the power plant.

Fuel system

The Fuel system are the tank, fuel pump, filters and injectors. Fuel before you get in the diesel engine D-160, passes through the system of 3 filters:

  • The first is installed in the filler neck of the tank for the preliminary treatment of fuel;
  • Second, designed for rough clean, is mounted before the booster pump;
  • Third, necessary for thin clearing of fuel, installed directly before the injection pump.

The Additional pre-charging pump acts as an intermediary between tank and fuel pump. It is also used to remove air from the lines and build up pressure in the system in engines with elektrofikatsii devices.

Features of the fuel system

In the cover headlight fuel pump high pressure set screw, which limits the capacity of the power plant during the break-in techniques. The injector is fixed in the head of each cylinder of swivel levers.

diesel engine d 160

Noteworthy electrically mechanism installed in the engine D-160. Device the EFA is a pin the candle and sealed it with a solenoid valve. Fuel evaporates directly into the candle, and then the mixing of fuel vapour with air and the detonation from the heated spiral candles. The resulting flame torch simultaneously heats the incoming air to the cylinders, thereby facilitating starting of the motor.

System supply air and lubricant

The air supply is carried out using a purifier consisting of 12 once-through cyclones, and the turbocharger 8,5 S. the Latter is due to the exhaust. They spin a radial centripetal turbine. During operation, there is no element of the system does not require regulation, but it is necessary to monitor the operation of the compressor. To understand the mechanism of power air alone is not recommended.

engine D 160

The Amount of engine D-160 is about 14 liters, and its operation depends on the lubrication system. Therefore, in the construction of the power plant presents it combined – a lubricant carried by the gear pump and the sprinkler. Before feeding the engine oil into the system it passes through a filter with replaceable paper elements. For ease of control of the resource filter on its side face, a pollution indicator of replacement parts.

Before starting the engine Makasarashvili the pump creates in the system the excess pressure, thereby facilitating operation of the power plant.

Engine specifications

Thanks to the coordinated work of the above components and mechanisms almost flawlessly and with a minimum consumption of fuel (for this class of car) the engine is operating the D-160. Technical characteristics of the power plant, located at such a high level, is also largely dependent on structural elements of the motor.

Needless to say that the manufacturer comes to market several modifications of the engine. Each unit differs only in its technical characteristics.

engine d specifications 160

The Engine D-160 is the brainchild of the Chelyabinsk tractor plant. Despite its venerable age, it can give odds to many modern power unit. However, like any other motor, it periodically needs to be repaired.

Due to the high maintainability and availability of spare parts maintenance issues arise. The only thing of concern – this is a complete overhaul.

Second life engine

If, during operation, a decrease in cylinder compression, uneven idling, increased fuel consumption, and the emergence of strong vibration and abnormal noise, you should know that your engine D-160 spare parts will not save. Then you need an overhaul.

Major restoration is an inevitable stage in the life of each power plant. It is important that it is done thoroughly. The price of a new power plant is at the level of 240 thousand rubles, which is why the overhaul is a better alternative. During repair operations desirable replacement for:

  • Piston group;
  • Indigenous and connecting rod liners;
  • Intake and exhaust valves of the cylinder head;
  • Rod bushings;
  • Oil pump;
  • Shims and rubber components.

During restoration work it is also necessary to check the operation of the fuel system. The most vulnerable elements are the nozzles and plunger pairs of the fuel high-pressure pump. In addition, the following things are checked and the starter motor. In some cases it cannot be recovered. Then the only one way – complete replacement of the mechanism.

The characteristic of engine D-160 is not able to fully describe its functional and technical features. Through his work, combined with the powerful gear unit is operating his tractors belong to the 6 and 10 traction class, are highly efficient and economical representatives of caterpillar equipment.
