Hot sale of boat tachometer from Nanjing Hemu International Trade Co.,LTD. Load rate refers to the ratio of the effective power emitted at a certain speed to the maximum effective power emitted at the same speed. Generally, when the engine load rate is 50% - 70%, the fuel efficiency is the highest. The maximum effective power that the engine can produce is proportional to the effective torque and speed. When driving on a flat road (flat ground), if the engine speed is high, the speed is low, and the load rate is low . On the contrary, if the engine speed is low and the speed is high, the load rate is high. Automobile manufacturers usually recommend a reasonable speed range in the vehicle instructions, and explain the relationship between gear, speed, fuel consumption and noise. However, the instructions usually do not provide gear information at any speed, and users need to obtain these experiences through actual shipping.

Use the tachometer to judge whether the ship starts. Nowadays, the noise of ship engine is low. Sometimes in a slightly noisy environment, it is difficult for us to judge whether the engine has been started by sound. Some novices will make a wrong judgment, which may start the engine again, causing damage to the ship's motor. The correct way is to observe the ship's tachometer.

Displays the safe working area of the boat engine. The rotating speed of the engine is displayed from low to high according to the clockwise rotation direction of the ship's tachometer. If the pointer points to the red marked part on the tachometer, it means that your ship's engine has been running at high speed. Too high speed for a long time will cause abnormal lubrication function of the engine, too much burden on the heat dissipation system, and great damage to the engine.

These parameters can reflect the working state of the boat engine. For example, unstable idle speed indicates dirty throttle or ignition system failure. Low maximum speed indicates that the engine performance has decreased, which may be due to excessive fuel supply system or mechanical wear. Watch the tachometer of the ship, reflect the operation of the engine in time, and let the driver better cooperate with the transmission gear and throttle position, so as to keep the ship in the best working condition, so as to reduce fuel consumption and prolong the service life of the engine.
