marine diesel tachometer

• 2023-05-26

Our tachometer can be used on marine diesel engine . I think the marine diesel engine tachometer has the following functions: firstly, it is used to adjust the idle speed; Secondly, do not exceed the red sign when cycling. What is the relationship between the rotational speed of a marine diesel and its speed? When starting in first gear , the engine speed is usually around 2000-3000 rpm . In fact , there is no need to pay too much attention to the speed . After shifting into first gear , slowly release the clutch.

When the marine feels like moving forward, slowly refuel while continuing to slowly release the clutch, and you can start smoothly. If the speed is too low , it is easy to hold the marine and turn it off, while if the speed is too high, it is easy to turn the marine on . The key to this problem is the appropriate oil separation fit, not just the engine speed. The speed and speed during upshifting and downshifting are not absolute, and should be determined based on the specific marine speed , sea conditions , and other factors at the time. The principle is to upshift the diesel engine in a timely manner if you feel that it has excess power. Conversely, if you feel that the power is insufficient, you should downshift in a timely manner. 

Generally, as long as you start, you should shift to second gear in a timely manner. For speeds above thirty, you can use third gear, and for speeds above forty, you should use fourth or fifth gear. Generally, only when driving at medium speed in fifth gear will the engine speed be basically equivalent to the vehicle speed, and in different gears, the same engine speed will also have different speeds, At medium speed, if the gear is low, the speed is relatively high, while if the gear is high, the speed is relatively low. The timing and speed of gear changes are a process of gradually mastering the marine diesel. Before becoming proficient and during practice, one should not be limited to the engine speed, but should feel the power output of the engine. Alternatively, gear changes should be based on the marine diesel speed rather than the engine speed. Whenever a gear change is made, the throttle should be retracted, and the speed at this point will decrease.
