The forced recirculation mixer (1) consists of a stirring enclosure (5) whose internal cavity forms a recirculation loop (6) in which circulates a homogeneous gas mixture (4) formed by a gas (3) to be mixed and a vaporizable liquid (2) respectively introduced into that loop (6) via a gas inlet duct (7) and a liquid injection nozzle (9), gas drawing-off means (12) being capable of withdrawing a homogeneous gas mixture (4) from the stirring enclosure (5) via a mixture draw-off duct (11) and a stirring turbine (13) driven by a turbine motor (28) forcing the homogeneous gas mixture (4) to circulate in the recirculation loop (6).

Methods and systems for operating an engine that includes two fuel pumps are described. In one example, a first fuel pump may be activated or remain activated in response to an engine shutdown request so that a second fuel pump may be cooled before the first fuel pump is deactivated in response to the engine shutdown request.

Disclosed are example embodiments of a fuel injection device having a plunger that moves at a predetermined reciprocating motion from an initial position, the fuel injection device includes: an electromagnetic coil; a tubular bobbin within the electromagnetic coil, wherein the electromagnetic coil is configured to move the tubular bobbin when energized; a fuel intake channel; and an inlet check valve disposed along a fuel pathway of the fuel intake channel, the inlet check valve configured to allow fuel to flow through and to a pressurization chamber, wherein the inlet check valve is a normally open valve.

A fuel injector is provided. The fuel injector includes a sleeve having a first end proximate an outlet; a piston slidingly received in the sleeve, the piston having a first end proximate the outlet; a pumping chamber at least partially defined by the sleeve between the first end of the piston and the outlet; and a normally-open inlet valve through which fuel passes to enter the pumping chamber.
