Power supply and lubrication system of the YaMZ-236 diesel engine
Power supply system (fuel system) of the YaMZ-236 engine and its components
Fuel supply equipment for the YaMZ-236 diesel power supply system for Ural, Maz, and T-150 tractors is of a divided type.
Fuel system The YaMZ-236 diesel engine consists of a fuel pump high pressure with all-mode speed controller and built-in corrector for correction fuel supply, fuel priming pump, injection advance clutch or without it, injectors, coarse filters and fine cleaning fuel, low and high pressure fuel lines.

fuel tank
From the tank, through a coarse filter, fuel is sucked in by the fuel priming pump of the engine of the Ural, Maz, and T-150 tractors and supplied to the fine filter and then to the high-pressure fuel pump.
The fuel pump, in accordance with the operating order of the cylinders, supplies fuel through high-pressure fuel lines to the injectors, which spray it into the engine cylinders. Through the bypass valve in the fuel pump and the jet in the fine filter, excess fuel, and along with it the air that has entered the system, is discharged through the fuel line into the fuel tank. The fuel that has leaked into the cavity of the injector spring is discharged through the drain pipeline into the tank. Coarse filter
internal combustion engine fuel
The filter element is a fleecy cotton cord wound on a mesh frame. The filter element is tightly clamped at the ends between the lid and the bottom of the cap. The hole in the cover, closed by plug 4 with gasket 3, is used to fill the filter with fuel.

Fine filter for diesel internal combustion engine YaMZ-236
The fine fuel filter for Ural and Maz vehicles and the T-150 tractor (Fig. 34) consists of a cap 5 with a rod 6 welded to it, a cover 8 and a filter element 4.
A drain plug 1 with a gasket 2 is screwed into the rod from below. The seal between the cap and the lid is provided by a paronite gasket 7. The cap and the lid are connected by a bolt 12, under the head of which a sealing washer 13 is placed.
A nozzle 12 is screwed into the cover, which is sealed with a gasket 10. Some of the fuel is drained through the nozzle along with the air that has entered the system low pressure.
On the engines of Ural and Maz cars and the T-150 tractor, equipped with an electric torch device, instead of a jet, a jet valve 15 is installed in the filter.
At low pressure in the system, which can be observed when starting the engine, fuel does not drain, and the fuel supply to the ECU is improved.

To drain sludge from fuel filters for coarse and fine cleaning, unscrew 3-4 turns drain plugs and pour 0.1 liters of fuel into a placed container.
After draining the sediment, tighten the plugs and run the engine for 3-4 minutes to remove air jams. Draining the sludge is especially important in the winter to remove condensing water.
Fuel lines of the YaMZ-236 engine
To supply fuel to the pump and injectors, as well as to remove excess fuel, the YaMZ-236 engine of Ural and Maz vehicles and the T-150 tractor has a system of low and high pressure fuel lines.
Low pressure fuel lines are connected with hollow bolts or union nuts through ferrules attached to the ends of the fuel lines. The contact surfaces are sealed with copper washers 1.5 mm thick.
YaMZ-236 high-pressure fuel lines have the same length for all engine cylinders. The ends of the fuel lines are set in the shape of a cone and pressed with union nuts to the fittings of the high pressure fuel pump and injectors. To avoid damage to fuel lines due to vibration, they must be secured using special brackets.
The order of operation of the sections for different models The injection pumps are different, therefore the connection schemes for the high-pressure fuel lines of the injection pump sections and the injectors of the engine cylinders are different.
Lubrication system of the YaMZ-236 diesel engine
The lubrication system of the YaMZ-236 engine of Ural, Maz, and T-150 tractors is mixed, with a “wet” sump (Fig. 36).
The YaMZ-236 oil pump (Fig. 37), through a suction pipe with an intake, sucks oil from the crankcase and supplies it to system through, series-connected liquid-oil heat exchanger (if equipped).

A bypass valve is installed in the heat exchanger body (plate). If the pressure difference before and after the heat exchanger reaches 274±40 KPa (2.8±0.40 kgf/cm2), the valve opens and part of the oil is supplied directly to the oil line.
On the YaMZ-236N,B engines of Ural and Maz cars, and the T-150 tractor, instead of a throttle, a valve is installed that stops the oil supply to the injectors when the oil pressure in the lubrication system is below 300...350 kPa (3.0...3.5 kgf/cm2).
The other part goes into the oil filter (Fig. 38). A bypass valve is installed in the filter housing. When the pressure difference before and after the filter reaches 200...250 kPa (2.0...2.5 kgf/cm2), the valve opens and part of the crude oil is supplied directly to the oil line. By the time the opening begins bypass valve
the moving and fixed contacts of the signaling device will close.
At this moment, a warning light connected to the signaling device terminal lights up in the driver’s cabin. This increase in pressure can occur when the filter element is clogged or the oil has a high viscosity (for example, when starting the engine in the cold season).
