tachometer gauge for small small engine

• 2023-03-07

The tachometer can be used to determine whether the car really starts. Some novice drivers are often not sure whether they have successfully started the car when they start the ignition, and some will turn the key again at this time, but this will damage the starting motor. The best way is to look up at the tachometer. As long as it is stable between hundreds of revolutions, it means that the car has successfully started.

The tachometer allows you to determine the timing of gear change. In the manual gear, when the car small engine reaches 2000 rpm to 3000 rpm , the shift consumption is the least . Therefore , the tachometer can just help us determine the best shift time. There is a red area on the tachometer . When the pointer reaches here , it indicates that the small engine speed has reached more than 6000 rpm . For the small engine , the red area is marked with the limit speed of the small engine . If the small engine is kept under high load for a long time , it will cause poor heat dissipation of the small engine and eventually damage the mechanical parts .

The car repair teacher Fu can judge the status of the car by the display on the tachometer when the small engine is idling , such as whether the small engine has carbon deposits , etc . The tachometer is an important reference to reflect the working conditions of the small engine . Learning to read the tachometer can save a lot of trouble . One use of the tachometer is to observe whether the car is started . When the car is not running , it will be at idle speed . At this time, the pointer of the tachometer will not be at 0, but above 700 rpm. So at any time, it is impossible to determine whether the vehicle has started. Just look at the tachometer . In the past , many people would shift gears according to the sound of the small engine , but now with the quietness of the whole car getting better , the small engine sound is basically not heard . The most correct method is to determine the speed of the small engine . At this time , the tachometer is in use.
