marine tachometer with hour meter

The pulse signal received by the marine tachometer will indicate the corresponding speed value after processing. There is an hour meter under the tachometer, which adopts liquid crystal display, which is simple and generous.

The marine tachometer can be used to determine whether the car really starts. Some novice drivers are often unsure whether they have successfully started the car when the ignition was on. Others will unscrew the key at this time, but it will damage the starting engine. The best way is to look up at the speedometer. As long as it is stable between hundreds of speeds, it means that the car has been successfully started. Assist the driver to maintain the engine and drive the vehicle at a reasonable speed If the idle speed of the engine is abnormal or the speed is unstable, it should be maintained in time to avoid increased fuel consumption and excessive emissions. Although the safe speed range for starting is very wide, try not to keep the speed within the safe speed range, otherwise it will aggravate the wear of the engine and significantly increase fuel consumption and noise.

The marine tachometer allows you to determine the shift time. In the manual transmission, when the automobile engine reaches 2000 to 3000 revolutions, the shift consumption is the least. Therefore, the speedometer can help us determine the best shift time. During driving, the engine speed should reach the reasonable speed range of corresponding working conditions to output effective torque and effective power suitable for working conditions, so as to make the engine run smoothly. However, in order to protect the engine, improve fuel efficiency and reduce engine noise, it is also necessary to adapt to the speed, even if the engine speed is within a reasonable range, so that the engine load rate 2) is at a medium level, so the gear should be adjusted in time.

There is a red area on the marine tachometer, where the pointer indicates that the engine speed exceeds 6000 rpm. For the engine, the red area marks the limit speed of the engine. Long term maintenance in high-load sports will cause poor heat dissipation of the engine and eventually damage mechanical parts. The teacher who repairs the car can judge the state of the car by the display on the tachometer when idling, such as whether the engine has carbon deposition. The tachometer is an important reference to reflect the operation of the engine. Learning to read the tachometer can save a lot of trouble.
