Page 35: Air Inlet And Exhaust System Of Diesel Engine
③ Generally, the ideal temperature difference between the inlet and outlet of the water tank is within 6-10℃. The wind velocity is 6-10m/s. The speed of fan blade rim must not exceed 90m/s. The effective cooling air volume required by the diesel engines at power station is 1.1-1.4 m3/min•kW. And the area of the water tank facing the wind is 0.35-0.40/m2/100Kw. -

(2) Supercharged inter-cooler. Select the supercharged inter-cooler in accordance with the air inlet flow rate and heat taken away by the supercharged air. Under standard environment, the air temperature getting into the diesel engine through the inter-cooler should be within 45-50℃, which is specified in the emission requirements. - Page 37 The operating speed governing lever can control the engine operation. When the lever is at the position of the idle speed limit screw, the engine is operation at idle speed. When the lever is at the position of maximum fuel supply, the engine is running at the maximum idle speed(the maximum speed rate without load).

10. Engine Operation 10.1 Preparation before engine start (1) Selection of diesel Sulphur content of the diesel will directly determine the emission of engine. Please use diesel compliance with the sulfur content requirements of emission. Users should choose proper grade of diesel according to the ambient temperature. At low temperature in winter, diesel with low freezing point is recommended to use. -
Page 40: Getting Prepared Before Starting The Engine
In addition, lubricating oil must be kept clean to avoid confusion of lubricating oil of different grades. (3) Selection of cooling liquids Like fuel and lubricating oil, cooling liquid is also crucial for diesel engine. Correct selection of cooling liquids and proper maintenance of cooling system can prevent many failures concerned with the cooling system, such as overheat of diesel engine, leakage of coolant pump, blockage of radiator and cavitation erosion of cylinder liner. -

(6) In the event of chill and freezing temperature, diesel engine must be put in a warm place resisting cold and freeze. When engine is operating in the open air, warm up the oil pan and heat the cooling liquid before starting the engine. -
Page 42: Engine Shut-Down
10.5 Engine shut-down (1) Remove the load and operate the engine at low or idle speed for 5 minutes before shut-down. For supercharged diesel engine, a certain period of operation without load before engine shut-down can protect the supercharger from damage due to hot load. (2) If anti-freezing agent is not used at a temperature lower than 5℃, drain coolant promptly after engine is shut down to prevent damage of engine block. - Page 43 Check the lubricating oil level Daily maintenance Check the cooling liquid level Check the tightness for joints of fuel, water and air pipelines; troubleshoot any defect. 9~11 The same as the contents for daily maintenance Check the air intake system Every three months Check the air filter or 300 hours...

Do you have a question about the BS-20KVA and is the answer not in the manual?
Questions and answers
What causes low oil pressure?
Low oil pressure in a Bison BS-20KVA can be caused by:
1. Excessively low oil level or poor/thin oil quality.
2. Broken oil pipe, loose pipe joint, or damaged oil pressure gauge causing leakage.
3. Deformation or breakage of the oil pump pressure adjustment spring.
4. Excessively large clearance in the oil pump.
5. Broken oil pump gasket.
6. Excessively large clearance between bearings.
7. Loose or leaking plug screw in the oil passage.
