Heavy equipment engine fault diagnostics

Timely engine diagnostics helps detect problems at an early stage and prevent serious failures. In this guide, we review the main signs of heavy equipment engine faults and diagnostic methods.

Osnovnye priznaki neispravnostey engine

1. Starting problems

If the engine does not start or is difficult to start, possible causes include:

• Discharged battery — check battery voltage
• Faulty starter — check starter operation
• Fuel system problems — check fuel filter and pump
• Problems with the ignition — check spark plugs and the ignition system

2. Loss of power

If the engine loses power, check:

• air filter — zagryaznennyy filter snizhaet power
• fuel filter — zasorennyy filter ogranichivaet podachu fuel
• Turbonadduv — check operation turbiny
• system cooling — peregrev snizhaet efficiency

3. Povyshennyy raskhod fuel

Uvelichenie raskhoda fuel can byt vyzvano:

• Nepravilnoy regulirovkoy fuel system
• Iznosom forsunok
• Problemami s sistemoy cooling
• Nizkim kachestvom fuel

4. Neobychnye zvuki

Razlichnye zvuki mogut ukazyvat na Problems:

• Stuk — can ukazyvat na iznos bearings or porshnevoy groups
• Svist — vozmozhna utechka air or Problems s turbinoy
• Skrip — can byt svyazan s remnyami or podshipnikami

5. Dym iz vykhlopnoy truby

Tsvet dyma can mnogoe rasskazat o sostoyaniand engine:

• Chernyy dym — pereobogashchenie toplivnoy smesi, Problems s forsunkami
• Belyy dym — popadanie okhlazhdayushchey fluids in cylinders
• Siniy dym — sgoranie engine oil, iznos porshnevykh kolets

Metody diagnostiki

Visual inspection

Nachnite s vizualnogo osmotra:

• check uroven and condition oils
• Osmotrite engine na nalichie utechek
• check condition remney and shlangov
• Osmotrite air and fuel filters

Diagnostics of s pomoshchyu priborov

Ispolzuyte diagnosticheskoe equipment:

• Skaner oshibok — for chteniya kodov neispravnostey
• Manometr — for proverki davleniya oils and fuel
• Kompressometr — for proverki kompressiand in tsilindrakh
• Multimetr — for proverki elektricheskikh systems

Analiz oils

Laboratory analysis oils pozvolyaet vyyavit:

• Iznos engine parts
• Popadanie okhlazhdayushchey fluids in oil
• Zagryaznenie oils toplivom
• condition prisadok in masle

We offer uslugi oil and technical fluid analysis for condition diagnostics of your equipment.

Tipichnye neispravnosti and ikh resheniya
