The DB4 engine tachometer can be used for speed measurement on any model of gasoline and diesel engine, 2-stroke or 4-stroke, single cylinder to 12 cylinder. If the measurement is taken from the vehicle battery, the number of cylinders ranges from 1 to 8.

Measurement can be carried out through the following methods:

◆ Sensor cables collect vehicle battery signals;

◆ Photoelectric sensors and reflectors are installed on diesel and gasoline engines, pulleys, and other rotating parts;

◆ The induction clip is stuck on the ignition coil with a distributed ignition system;

◆ Piezo is clamped onto the diesel engine injection pipe;

◆ Induction pliers are used for high-pressure common rail engines.
