4.27. Possible malfunctions of the engine, their reason and ways of elimination

Cause of defect
Way of elimination
The engine is not started up
There is no pressure of fuel in a stage:
Are littered топливопроводы;

The fuel pump is faulty;
The fuel filter is littered;
The regulator of pressure of fuel is faulty

Wash out and blow a fuel tank and топливопроводы;
Replace the pump;
Replace the filter;
Check up a regulator, faulty
Replace
The ignition system is faulty
«The control system of the engine» see
The engine works unstably or глохнет idling
Pressure of fuel does not suffice in
топливопроводе the engine ("stage")
The Engine see «is not started up»
The idling regulator is faulty
Replace an idling regulator
Подсос air through ventilation hoses
crankcase the engine and a hose connecting the inlet pipeline with the vacuum
The amplifier of brakes
Tighten collars of fastening,
The damaged hoses replace
Backlashes between levers and camshaft cams are broken
Check up hydrosupport, not serviceable replace
The ignition system is not serviceable
«The control system of the engine» see
The engine does not develop a total power and does not possess sufficient приемистостью
Incomplete opening throttle заслонки
Adjust drives throttle заслонки
The gauge of position throttle заслонки is faulty
Replace the gauge
Pressure of fuel in топливопроводе does not suffice engine ("stage")
The Engine see «is not started up»
The air filter is polluted
Replace filtering element
The ignition system is faulty
«The control system of the engine» see
Backlashes between levers and camshaft cams are broken
Check up hydrosupport, not serviceable replace
Insufficient compression - more low 1 МПа (10 kgs/sm2):
The lining of a head of the block is punched
Cylinders;
Burn-out of pistons, breakage or
залегание piston rings;
Bad прилегание valves
To saddles;
Excessive deterioration of cylinders and piston rings
Execute the following:

Replace a lining;

Clear rings and flutes of pistons of a deposit, the damaged rings and the piston replace;
Replace the damaged valves, grind saddles;
Replace pistons, chisel and отхонингуйте cylinders
Knock of radical bearings of a cranked shaft
Usually knock of deaf tone, metal. It is found out at sharp opening throttle заслонки idling. Its frequency increases with increase
Frequencies of rotation of a cranked shaft. The excessive axial backlash of a cranked shaft causes knock sharper with the non-uniform intervals especially appreciable at smooth increase and reduction of frequency of rotation of a cranked shaft
Insufficient pressure of oil
Insufficient pressure of oil idling »see«
Bolts of fastening of a flywheel are weakened
Tighten bolts the recommended moment
The increased backlash between necks
And loose leaves of radical bearings
Прошлифуйте necks also replace
Loose leaves
The increased backlash between persistent half rings and cranked shaft
Replace persistent half rings new
Or the increased thickness
Knock шатунных bearings
Usually knock шатунных bearings is sharper than knock of the radical. It is listened idling the engine at sharp opening throttle заслонки. The knock place is easy for defining, disconnecting by turns spark plugs
Insufficient pressure of oil
Insufficient pressure of oil idling »see«
Excessive backlash between шатунными
Necks of a cranked shaft and loose leaves
Replace loose leaves and прошлифуйте necks
Knock of pistons
This knock usually not sonorous, muffled; it is caused by piston "palpation" in the cylinder. Is better it it is listened at small frequency of rotation of a cranked shaft and under loading
The increased backlash between pistons and cylinders
Replace pistons, chisel and отхонингуйте cylinders
Excessive backlash between the piston
Rings and flutes on the piston
Replace rings or pistons with rings
Knock of inlet and final valves
Work with the increased backlashes in клапанном the mechanism causes characteristic knock, usually with uniform intervals; its frequency less than any other knock in the engine as valves are put in action from a camshaft which frequency of rotation twice is less than frequency of rotation of a cranked shaft
The increased backlashes between levers
And camshaft cams
Check up hydrosupport, not serviceable replace
Breakage клапанной springs
Replace a spring
Excessive backlash between a core and directing the valve
Replace the worn out details
Deterioration of cams of a camshaft
Replace a camshaft and levers of valves
Excessive noise of a chain of a drive of a camshaft
From the general noise of the engine noise of a chain of a drive of a camshaft is allocated
At occurrence of backlashes between elements of gearing also it is accurately listened at small frequency of rotation of a cranked shaft
Ослабла a chain owing to deterioration
Replace a chain
Boot breakage натяжителя chains or
успокоителя
Replace a boot натяжителя or успокоитель
It is faulty гидронатяжитель chains
Replace гидронатяжитель
Insufficient pressure of oil idling on the heated-up engine
Hit under редукционный the valve
Pressure of oil of extraneous particles
Clear the valve of extraneous particles
And agnails, wash out the oil pump
Gear wheels of the oil pump are worn out
Repair the oil pump
Excessive backlash between loose leaves
And radical necks of a cranked shaft
Прошлифуйте necks also replace loose leaves
Excessive pressure of oil upon the heated-up engine
Jamming редукционного the valve of pressure of oil
Replace the valve
The raised expense of oil
Podtekanie oils through consolidations
The engine
Tighten fastenings or replace linings and epiploons
Deterioration of piston rings and pistons or
Engine cylinders
Chisel cylinders and replace pistons and rings
Breakage of piston rings
Replace rings
Закоксовывание маслосъемных rings or cuts in flutes of pistons
Clear cuts and rings of a deposit
Deterioration or damage маслосъемных
Caps of valves
Replace маслосъемные caps
The raised deterioration of cores of valves or directing plugs
Replace valves, repair a head of the block of cylinders
The raised expense of fuel
The raised resistance to movement
The car
Check up and adjust pressure in tyres, brake system, corners of installation of wheels
The ignition system is faulty
«The control system of the engine» see
Atomizers are faulty
"Power supply system" see
Подтекание fuel in connections
Pipelines
Tighten connections of pipelines
Use of bad quality fuel
Fill in recommended fuel
Weak tension of a belt of a drive of the pump and the generator
Adjust a belt tension
Insufficient quantity of a liquid
In cooling system
Add cooling liquid in cooling system
The external surface of a radiator is strongly polluted
Clear an external surface of a radiator a water stream
The thermostat is faulty
Replace the thermostat
The valve of a stopper of a radiator is faulty,
Pressure of opening is less 0,05 МПа
(0,5 kgs/sm2)
Replace a stopper
The pump of a cooling liquid is faulty
Check up pump work, replace it or repair
Fast falling of level of a liquid in a broad tank
The radiator is damaged
Repair a radiator or replace
Damage of hoses or linings to connections of pipelines
Replace the damaged hoses or linings
Podtekanie liquids from the heater crane
Replace the crane
Collars of hoses are poorly tightened
Tighten collars
Podtekanie liquids through an epiploon of the pump of a cooling liquid
Replace an epiploon
The stopper or lining of a stopper of a radiator is damaged
Replace a stopper
The lining of a head of the block is damaged
Cylinders
Replace a lining
Podtekanie liquids through microcracks in the block or in a head of the block of cylinders
Check up tightness of the block and a head of the block of cylinders, at detection of cracks replace the damaged details
Podtekanie liquids through microcracks in the case or a cover of the pump of a cooling liquid, a broad tank or an inlet pipe
Check up tightness, at detection of cracks the damaged details replace; the insignificant leak is supposed to be eliminated the additive in cooling liquid герметизатора type НИИСС_1
