What to do if Baudouin Engine is too hot?
- T
  Tammy ShafferAug 23, 2025
  If your Baudouin Engine is overheating, there are several potential causes to investigate. The engine may be experiencing overload, so reduce the load. There could be bad combustion, so check the injector. The lubricating oil level might be insufficient or excessive; adjust according to the oil dipstick. Other possible issues include a clogged oil cooler (clean or replace it), insufficient water pump flow (check the impeller gap and replace if necessary), low fan speed (adjust the fan belt tension), excessive lime scale in the cooling system (remove the lime scale), poor thermostat cooling effect (remove dirt from the radiator), or thermostat failure (check and repair).

Why Baudouin Engine exhaust gas is black?
- M
  Michelle YangAug 26, 2025
  Black exhaust gas from your Baudouin Engine could be due to a few reasons. The intake pipe might be clogged, or the exhaust back pressure could be high; in this case, clean the intake or exhaust pipe. Poor fuel quality could also be a factor; clean the fuel system and replace the fuel. Other possible causes include incorrect valve timing (adjust as required), unstable atomization of the fuel injector (check, repair, or replace it), insufficient pressure in the supercharging system (check and troubleshoot the leakage in the connecting pipe), turbocharger malfunction (check and replace the assembly), or a damaged intercooler causing leakage (replace or repair it).

What to do if Baudouin Engine stopped soon after starting?
- G
  gwhiteAug 28, 2025
  If your Baudouin Engine stops shortly after starting, it could be due to several reasons. There might be air trapped in the fuel system; check the fuel pipe and its joint for leakage, ensure the bleeder screw is tight, and expel the air from the fuel system. The fuel filter might be clogged; take down the filter body, remove dirt and moisture, and replace the filter element if necessary. Poor fuel quality with excessive moisture could also be the cause; clean the filter and replace the fuel. Additionally, the idle speed might be too low, requiring a readjustment, or the fuel supply pump may not be working, necessitating a check, clean, and repair of the supply pump and valve.

Why Baudouin Engine rotating speed is unstable?
- K
  Kathryn HuntSep 4, 2025
  Unstable rotating speed in your Baudouin Engine may be caused by several factors. Poor fuel quality with moisture or wax could be the issue; clean the fuel system and replace the fuel. Air might be getting sucked into the fuel suction pipe; check the pipe and its joint for tightness and expel any trapped air. Other possible causes include uneven fuel supply (check and adjust), unstable atomization of the fuel injector (check and repair), turbocharger surging (check and clean the compressor flow passage, removing fouling and soot deposition), or a damaged turbocharger bearing (replace).

Why Baudouin Engine has excessive noise level?
- D
  Debbie GallagherSep 8, 2025
  Excessive noise in your Baudouin Engine can arise from several sources. Poor fuel quality could be a contributing factor; replace the fuel. The coolant temperature might be too low; check and replace the thermostat. Other potential causes include incorrect valve timing or fuel supply timing (check, repair, or adjust), unstable atomization of the fuel injector (check, repair, or adjust), vibration damper failure (check and replace), valve leakage or improper adjustment (inspect and adjust), excessive gear clearance or broken gear teeth (check and replace the damaged gear), a worn cylinder liner or piston or piston scraping (check, repair, or replace), a bent or broken push-rod or a broken rocker arm (replace), or a broken or worn piston ring (replace the damaged piston ring).

Why is there too much oil accumulated at the air inlet port/pipe of Baudouin Engine turbocharger?
- D
  David SanchezSep 12, 2025
  Excessive oil accumulation at the air inlet port or pipe of your Baudouin Engine's turbocharger can be due to a few reasons. There might be turbocharger sealing failure, in which case you should repair or replace it. The oil-gas separator could have failed, requiring replacement. Alternatively, the oil pan liquid level might be too high; check and release oil as needed.

How to fix Baudouin Engine starter motor that does not work?
- M
  Michael KingSep 13, 2025
  If the starter motor on your Baudouin Engine isn't working, several issues could be the cause. A blown fuse could be the problem; replace the fuse. There might be poor circuit contact; check the circuit and tighten the terminals. Insufficient battery charge could also be a factor; check, recharge, or replace the battery. A short circuit in the starter motor could be the reason; inspect and repair the starter motor or replace the entire assembly. Lastly, poor contact of the electric brush could be the problem; clean or replace the electric brush.

Why Baudouin Engine starter motor is powerless?
- T
  taylorwilliamSep 15, 2025
  If your Baudouin Engine's starter motor is powerless, several factors could be responsible. The battery might be undercharged; recharge or replace it. A worn bearing bush could be the issue; replace the assembly. Poor contact of the electric brush could also be a factor; clean or replace the electric brush. Additionally, a terminal might be unsoldered, requiring it to be soldered again, or there could be poor contact of the switch; check and repair the switch.

Why Baudouin Engine has insufficient power?
- S
  sharon84Nov 18, 2025
  If your Baudouin Engine lacks power, the issue could stem from several factors: a clogged intake system (air filter)—inspect and clean or replace the filter element; high exhaust back pressure—check and adjust valve timing and inspect the exhaust pipe for blockages; or insufficient pressure in the supercharging system—check for leaks in the connecting pipe. Other possible causes include turbocharger malfunction (replace the assembly), clogged compressor/turbine flow passage (wash or replace), floating bearing failure (replace), carbon or sludge deposits on the turbine and compressor (clean), a damaged intercooler (replace or repair), fuel pipe leaks or clogs (check, tighten, and clean the fuel pipe, and replace the fuel filter element), poor fuel quality (clean the fuel tank, filter, and p...

Why Baudouin Engine has excessive fuel consumption?
- R
  Ronald LeeNov 20, 2025
  Excessive fuel consumption in your Baudouin Engine can be attributed to several reasons. The intake system might be clogged, so check the air filter and intake pipe for any blockages and remove them. High exhaust back pressure could also be a factor; inspect and clean the exhaust pipe. Other potential causes include poor fuel quality (replace the fuel), a clogged or leaking fuel pipe (check and remove any blockages or leakages), unstable fuel injector atomization (check, adjust, and repair the fuel injector), incorrect valve timing (adjust the valve clearance), cylinder gasket leaks (check the compression pressure in the cylinder), excessive bearing shell gap requiring a diesel engine overhaul (check and overhaul the engine), piston scuffing (replace the cylinder liner, piston, and piston ...
