INDUCTANCE

The inductance is 3.1 mH with open magnetic circuit at 1 kHZ and 300 mV

@ 20 °C

MINIMUM OPENING VOLTAGE

The injector opens for a minimum voltage of 4.4 volts

TEST PARAMETER: 20°C gas temperature, 4.5 bar inlet pressure TEST PROCEDURE: Starting from a voltage of 0 Volts, voltage is gradually increased by 1Volt/s and the voltage at which the injector has opened is observed by means of a flow meter. The test is performed using air as the gas, with an ambient and intake

gas temperature of 20°C and a relative pressure of 4,5 bar.
