1 cylinder analog tachometer

Our analog tachometer can use on 1 cylinder. Size include 52mm and 85mm . Look at the 1 cylinder tachometer. The red area is diesel when you get to more than 4000 , and the red area is only when you get to more than 7000 gasoline cars. The maximum indication of the tachometer of gasoline vehicles can be as high as 7000~8000 revolutions , some models can be as high as 10000 revolutions or more , and the maximum speed of single 1 cylinder motorcycles can be as high as 15000 revolutions or more . However , the maximum speed of the diesel vehicle's analog tachometer is generally about 4000 rpm. The truck's tachometer has a maximum speed of only 2800 rpm , and the most economical speed range is generally about 1500 rpm. It is not recommended to use the high speed range .

The red line speed of the 1 cylinder analog tachometer for gasoline vehicles is generally above 6000 rpm , while that for diesel vehicles is about 4000 rpm. In addition , the tachometer of diesel vehicles will generally be marked with economic speed, that is, the green area on the tachometer , so that the engine can work at this speed . The power and economy of the car are the best. However, this speed range is generally narrow . When driving on roads with large changes in road conditions, we need to change gears frequently to make the engine speed, transmission gear and speed coordinate .

Motorcycles are generally 1 cylinder engines. The tachometer signal of gasoline engines is the primary signal from the ignition coil. For a four stroke engine, the crankshaft rotates twice to generate an ignition signal. Then the crankshaft speed of a single cylinder engine is: 2 × Number of ignition signals generated within 1 minute.

In general, the tail signal indicator of the electronic 1 cylinder analog tachometer should use DC to have a stable power supply, so as to maintain the stability of the electrical components . The tachometer of the motorcycle is used to adjust the idle speed. the ignition wire of the engine . The engine will be ignited once every time the wire is used, that is, it will turn for 2 turns . According to this principle, each time the electromagnet is energized, the faster it rotates , the stronger the magnetic force is, and the pointer moves up.
