WHAT ARE THE CAUSES OF WHITE SMOKE IN A DIESEL ENGINE?White smoke in a diesel engine is usually caused by incomplete combustion due to: Low engine temperature (cold start) Faulty injectors or incorrect fuel timing Water or coolant mixing with fuel (blown head gasket, cracked cylinder head) Low compression due to worn-out piston rings or valves Ignoring this issue can cause serious engine damage, so it should be diagnosed and repaired immediately.
-
WHAT ARE THE COMMON PROBLEMS OF A GENERATOR?The most common generator problems include: Battery failure – Weak or dead battery preventing startup Fuel system issues – Clogged filters, air in fuel lines, or fuel contamination Overheating – Low coolant levels or radiator blockages Alternator failure – Worn-out brushes or damaged windings Control panel faults – Sensor failures or wiring issues Regular maintenance and timely servicing can prevent these problems and keep your generator in peak condition.
-
WHY WON’T MY GENERATOR START?A generator may fail to start due to: Dead or weak battery Faulty fuel pump or clogged fuel filters Low oil pressure or coolant levels triggering safety shutdown Worn-out starter motor Damaged glow plugs or injectors (for diesel generators) Checking these components and regularly servicing your generator can help prevent startup failures.
-
HOW TO SOLVE A DIESEL ENGINE LOCKED OUT ISSUE?A diesel engine lockout (engine refusing to start due to safety shutdown) can be caused by: Low oil pressure or high temperature shutdown – Check and refill fluids Emergency stop engaged – Reset the emergency stop button Fuel starvation – Bleed air from the fuel system Mechanical seizure – If the engine is completely locked up, it may need professional disassembly and repair If your diesel engine remains locked out, contact us for expert troubleshooting.
