Dongfeng Xiaokang k07 emits white smoke.

1, the temperature is not enough, because the engine temperature is not enough, part of the mixed gas formed by fuel and air injected into the cylinder can't burn, and the exhaust pipe emits white smoke. Therefore, after the locomotive starts, we should pay attention to the heat preservation of the water tank, run the throttle during use, and gradually increase the load when the temperature of the standby vehicle reaches above 50 degrees.

2. There is water in diesel oil and water in diesel oil, which directly affects the normal combustion of mixed gas and emits white smoke. At this time, the precipitated oil should be released and the accumulated water should be discharged. If necessary, the diesel oil should be replaced.

3. If the exhaust pipe continues to emit white smoke, it may be that the cylinder head and cylinder gasket of individual cylinders are damaged and water enters, so it should be removed for inspection and replaced with damaged cylinder head and cylinder gasket. In addition, if the intake valve is not tightly closed, white smoke will also appear, which should be inspected and maintained.
