Method for determining fuel quality of mixture composition of fuel for fuel pump, particularly fuel sensor, involves determining electrical parameter of fuel by electric motor, where electrical parameter is capacitive parameter

摘要

The method involves determining an electrical parameter of fuel (Kr) by an electric motor (12). The electrical parameter is a capacitive parameter or a resistive parameter for determining information through the fuel quality of the fuel. The electric motor has a stator (100) and a rotor (110). An independent claim is also included for a fuel sensor for a motor vehicle.
