Reasons for black smoke from diesel generator sets
- The intake air temperature is too high.
- The air filter is too dirty or the intake pipe is blocked.
- The injector is dripping oil or poorly atomized.
- There is a problem with the fuel injection pump.
- The fuel injection advance angle is incorrect.
- The valve clearance is incorrect.
- The cylinder is seriously worn.
- There is a problem with the supercharger.
How to calculate the fuel consumption of diesel generator sets
Another indicator of commonly used diesel generator sets that needs attention is fuel consumption. The full load fuel consumption of domestic diesel engines is generally 210g/kw.h to 240g/kw.h, the full load fuel consumption of joint venture brand diesel engines is generally 200g/kw.h to 220g/kw.h, and the full load fuel consumption of imported brand diesel engines is generally 190g/kw .h to 210g/kw.h. Don’t underestimate the difference of 10 to 20 grams of diesel per kWh of electricity. Taking a 500KW diesel generator set as an example, if it runs 10 hours a day and 20 days a month, the annual fuel consumption of a generator set equipped with a domestic diesel engine is: 210g/kw. h500KW10hours20days12months=252 tons, the annual fuel consumption of the generator set with imported brand diesel engine is: 190g/kw.h500KW10 hours20 days12 months=228 tons, a difference of 24 ton, calculated at 8,000 yuan per ton of diesel, diesel can save 192,000 yuan per year.
