Does a China V diesel engine make a clanking sound at idle?
1 Answers
If a China V diesel engine makes a clanking sound at idle, it is necessary to stop the vehicle immediately for inspection and troubleshooting to prevent serious accidents. Precautions for diesel generator sets during idle operation: After starting, diesel generator sets require 3-5 minutes of idle operation. It takes some time for the oil film to be re-established between the crankshaft and bearings, as well as between the piston and cylinder liner. The optimal clearance between moving parts can only function properly when the engine reaches a certain temperature. Therefore, at the initial stage of startup, one should not rush to apply high power, large torque, or high speed to avoid piston seizure in the cylinder or dry friction in the bearings. How to correctly select diesel engine speed: When choosing the operating speed of a diesel engine, not only the fuel economy and power performance of the diesel engine should be considered, but also the vehicle's driving speed. If the speed is maintained between the maximum torque speed and the minimum fuel consumption rate during operation, although the economy and torque of the diesel engine are good, the effective power of the diesel engine cannot be fully utilized, and the rapid driving performance of the diesel vehicle cannot be realized. Therefore, the correct selection of diesel engine speed should combine power, torque, and fuel consumption rate, using gear shift control.
