Disadvantages of the BHDA/BHDB engine
Although this diesel engine requires a lot of fuel, it runs smoothly when it is of high quality.
Low-quality diesel fuel rapidly deteriorates the high-pressure fuel pump and the nozzles;
Abrupt power outages may result from a dirty fuel filter;
Leaks frequently originate at the intersection of the cylinder block’s upper and lower sections;
An expensive turbine is in danger after 150–200 thousand kilometers of operation.
