An injection device for an internal combustion engine is described, which has a first fuel injector for injecting fuel having a first fuel composition based on ethanol, and a separate second fuel injector for injecting fuel having a second fuel composition, which differs from the first fuel composition, the injection device having a heating device for preheating exclusively the fuel having the first fuel composition and injected by way of the first fuel injector.

Injection device, internal combustion engine, and method for operating an internal combustion engine

An injection device for an internal combustion engine is proposed having at least one injection valve system for injecting fuel into an intake manifold of the internal combustion engine and at least one heating device for pre-heating fuel injected by the injection valve system, the injection valve system including a first injection valve for injecting fuel in the direction of a first inlet opening of a combustion chamber of the internal combustion engine and a separate, second injection valve for injecting fuel in the direction of a second inlet opening of the combustion chamber.

Injection device and internal combustion engine having a heating device

A determining device for determining at least one component of a liquid, e.g., a fuel mixture, for use in motor vehicles, includes at least one sensor which has at least one connecting device for coupling microwave signals into the liquid and/or out of the liquid. The determining device is implemented as a hand-held measuring instrument.

Device for determining a composition of a liquid

A method for detecting the tank fuel level of a motor vehicle includes: ascertaining the tank level sensor signal (U) of a tank level sensor, determining a calculated tank level (F) as a function of a fuel quantity consumed by the internal combustion engine, and providing a corrected tank level signal as a function of the tank level sensor signal (U) and the calculated tank level (F).

Method and device for detecting a tank level

In a method for operating an internal combustion engine of a motor vehicle, a driver type is ascertained. A criterion for performing a diagnosis or a regeneration of a component of the fuel supply system is a function of the ascertained driver type.
