A system and method to enable electronically controlled internal combustion engines to self-adjust parameters and operate properly on different fuels that have wide ranges of physical and chemical properties. Input from a sensor is utilized that gives a signal indicative of the combustion process. The ECU processes the signal and readjusts the engine operating parameters to achieve its operating goals.

Various methods and systems are provided for indexing an injector map and subsequently controlling fuel injection to an engine. In one embodiment, a method for the engine includes injecting fuel via activating an injector for a determined activation time, the activation time determined based on a commanded fuel value and a function of a modified pressure difference across an orifice of a nozzle of the injector, where the modified pressure difference is based on a difference between a rail pressure and peak cylinder pressure, the peak cylinder pressure scaled by a function of engine speed and injection timing and the pressure difference offset by a correction factor.

A dual-chamber onboard electrolysis system is configured to produce HHO gas for heavy duty trucking applications.

The invention relates to a fuel injector arrangement (1) comprising a number of fluid supply paths (29, 31, 39), namely, a first (29), a second (31) and a third fluid supply path (39). The fuel injector arrangement (1) has a first switching device (43) in the second fluid supply path (31). Said first switching device, controlled by the fluid pressure in the third fluid supply path (39), opens or blocks the second fluid supply path (31). The fuel injector arrangement (1) has a second switching device (49) in the first fluid supply path (29). Said second switching device, controlled by the fluid pressure downstream of the first switching device (43) in the second fluid supply path (31), opens or blocks the first fluid supply path (29).

A method for operating a motor vehicle provided with a hybrid drive apparatus. The hybrid drive device is equipped with an internal combustion engine that can be operated with a fuel, as well as with an electric engine, and a lubricant is supplied at least intermittently to the internal combustion engine. At the same time, a lubricant dilution value is determined with a dilution of the lubricant so that the internal combustion engine is started when a first threshold value is exceeded by the lubricant dilution value, and when the motor vehicle is located on a regeneration route of an anticipated driving route of the motor vehicle and the regeneration route is sufficient to reduce the lubricant dilution value by a specified value.

Disclosed is a compression ignition engine including a first fuel supply supplying naphtha, a second fuel supply supplying diesel fuel, an EGR gas recirculation portion recirculating exhaust gas back to a combustion chamber, and a controller controlling these components. The controller determines whether an engine body is operated in a low load region or a high load region. In the low load region, the controller outputs a control signal to the first fuel supply so that at least naphtha is supplied, and outputs a control signal to the EGR gas recirculation portion such that an EGR rate becomes higher than that when the engine is operated in the high load region to make an air-fuel ratio fall within a range of 14.5 to 15.0.

Embodiments of the present invention include a method and apparatus for supplying conditioned natural gas to dual fuel engines.

Disclosed are a method and system for controlling fuel injection in response to a change in the content of ethanol in a FFV having oxygen sensors and an ethanol sensor. The system includes an ethanol content change detection unit configured to detect a change in the content of ethanol, a flow rate calculation unit configured to calculate a volumetric flow rate of blending fuel and to integrate the calculated value, a condition determination unit configured to determine whether the change in the content of ethanol satisfies a condition for applying a fuel injection correction value, a control execution determination unit configured to determine whether to apply the fuel injection correction value by comparing the volumetric flow rate integration value with a preset second reference value, and a controller configured to determine a fuel injection correction value and to adjust an amount of fuel injection.

When the male quick connector (10) is connected to the female quick connector (7), the trigger tab (101) is against the reed (91). A knob component (6) is connected with the fuel valve (5) to control fuel flow in the fuel pipe (4), and the engine flameout is also controlled by the knob component (6).

A valve device for liquids, especially for liquid plastic constituents of single- or multiple-constituent plastic mixtures, includes a valve housing with a liquid inlet and a metering valve, which has a discharge opening that can be closed by a closure element, a pressure control device acting on the liquid in the liquid inlet and comprising a control membrane which acts on the closure element. A shut-off diaphragm separates the pressure control device from the liquid inlet, and the pressure control device comprises a fluid-tight control chamber which is at least partially arranged in the valve housing, for storing a substantially incompressible fluid. A pressure generating device allows the control membrane to be subjected to pressure by the incompressible fluid arranged in the control chamber.
