How to Decrease the Consumption of Diesel Generator

The main fuel used in diesel generators is diesel fuel, and the cost of using it continues to rise as oil prices continue to rise. There are many users who are concerned about the fuel consumption of diesel generator sets. So how to use diesel generator more fuel-efficient? What details should you pay attention to in the process of using? In the operation of diesel generator set, because of the high temperature produced by the relevant parts during combustion, the ash carbon polymer is attached to the valve, valve seat, fuel injector, piston top and so on. Failure to clean up in time will increase fuel consumption and seriously affect the normal operation of the engine. In general, it is best to clear it once a month for 4-6 months. At the same time, the cooling water temperature of diesel generator set should be kept around 45-61 ℃ , if the water temperature is too low, it will cause incomplete combustion of diesel oil and increase the load of the machine itself. Cooling w...

Instructions to Do Diesel Generator Set Commissioning

Diesel engine unsealing In order to prevent the diesel engine from rusting, when the product leaves the factory, both inside and outside is sealed with oil. Therefore, after the new unit is installed and meets the installation requirements, it must be unsealed before it can start. Otherwise, it will cause the danger. So it should be taken seriously. The steps to remove the oil seal are as follows: 1) Heating the diesel above 45 ℃ to 56 ℃ for cleaning and removing the external anti-rust oil. 2) Heating water aover 90 ℃ , then continuously pouring water through the water jacket outlet, flowing out from the plug assy Irain (or water pump inlet) on the side of the cylinder body, continuously for 2--3 hours, and rolling the crankshaft  discontinuously to make the anti-proof oil of piston top, cylinder liner surface and elsewhere dissolves and flows out. 3) Clean the oil sump with clean diesel oil and replace it with new oil. Cooling and fuel system, ...

How to Adjust Valves of Cummins NT Engines

This post is mainly written to introduce how to adjust crosshead, injector and valves of Cummins NT diesel engines correctly. Pay attention to reading and you will learn more. Crosshead Adjustment Note: Crosshead adjustment should always be made before attempting to adjust the valves. 1. Loosen the locknut on the crosshead adjusting screw. Turn the adjusting screw out at least one turn. 2. Hold the crosshead down against its mating valve stem. Turn the adjusting screw back in until it touches the valve stem. Hold the adjusting screw in this position and tighten the locknut. 3. Tighten the adjusting screw locknut to 25 to 30 ft-lb [34 to 41 N*m] torque. Note: When ST-669 Torque Wrench Adapter is used, tighten the locknut to 22 to 26 ft-lb [30 to 35 N*m] torque. 4. Check the clearance between the crosshead and valve spring retainer 1 and 2. Fig. 2-19 with a wire gauge. Tighten must be a minimum of 0.025 inch [0.64 mm] clearance. Valve Adjustment The ...
