Reasons why small diesel engines are difficult to start and their solutions
  2023/11/07| View:826

1. Fuel system failure

A common cause of difficulty starting in small diesel engines is fuel system failure. Possible problems include a failed fuel pump, clogged fuel filter, leaking fuel lines, etc. Solutions include checking the working status of the fuel pump, cleaning or replacing the fuel filter, and repairing or replacing leaking fuel lines.

2. Electrical system problems

Electrical system failure is also one of the common causes of difficulty in starting a small diesel engine. Possible problems include a weak battery, faulty alternator, starter problems, and more. Solutions include checking the battery power, charging or replacing the battery; checking whether the generator output voltage is normal; checking the working status of the starter, and repairing or replacing faulty parts.


3. Air system problems

Difficulty starting a small diesel engine may also be related to the air system. Problems such as clogged air filter and air leakage in the intake pipe may cause difficulty in starting. Solutions include cleaning or replacing the air filter, and repairing or replacing leaking air intake lines.


4. Combustion system problems

Combustion system failure is also one of the reasons why small diesel engines have difficulty starting. Possible problems include clogged fuel injectors, damaged fuel injectors, carbon deposits in the cylinder, etc. Solutions include cleaning or replacing the fuel injector, repairing or replacing the fuel injector, and cleaning the cylinder.


5. Environmental factors

Environmental factors may also have an impact on the starting of small diesel engines. In low temperature environments, the fluidity of diesel oil becomes poor, which can easily lead to difficulty in starting. Solutions include using low pouring point diesel or adding diesel deicing agent to improve the fluidity of diesel; using a heater to preheat the diesel.


6. Improper maintenance

Improper maintenance of a small diesel engine can also lead to difficulty starting. For example, not using a diesel engine for a long time or storing the diesel engine for a long time without taking protective measures can easily lead to problems such as diesel aging and sediment accumulation. Solutions include running the diesel engine regularly to avoid long periods of outage, replacing diesel regularly, and keeping the diesel tank clean.


There are many reasons for difficulty in starting a small diesel engine. Common ones include fuel system failure, electrical system problems, air system problems, combustion system problems, environmental factors and improper maintenance. For specific problems, we can take corresponding solutions, such as checking and repairing fuel system faults, electrical system problems and air system problems, cleaning or replacing fuel injectors and injectors, using low pouring point diesel or adding diesel deicing agent , as well as regular maintenance and upkeep of diesel engines. By correctly identifying problems and taking appropriate solutions, we can improve the starting performance of small diesel engines and ensure their normal operation.
