A highly-efficient, yet simply constructed internal combustion engine includes an intake cylinder to accommodate intake and pre-compression of an oxidizing agent, a combustion cylinder to accommodate a further compression of the oxidizing agent, an injection and ignition of fuel, and a partial expansion of combustion gases produced by the ignition of fuel; and an exhaust cylinder to accommodate a further expansion of the combustion gases and subsequent exhausting of the further expanded combustion gases. A reciprocating piston is inside each of the intake, combustion and exhaust cylinders and a crankshaft is coupled to the reciprocating pistons. A first transfer passage facilitates flow of the pre-compressed oxidizing agent from the intake cylinder to the combustion cylinder and a second transfer passage facilitates flow of the partially-expanded combustion gases from the combustion cylinder to the exhaust cylinder.

A preheating device for an internal combustion engine may include an inlet connection for connecting a distributor rail of a fuel injection system and an outlet connection for connecting a fuel injector of the fuel injection system. A preheating chamber may be fluidically connected with the inlet connection and the outlet connection and be flowable through by a fuel flow. At least one electrical heating element may be included for heating the fuel flow in the preheating chamber. At least one metallic heating body, which may be exposed to the fuel flow in the preheating chamber, may receive the at least one heating element.

A mounting assembly for a fuel system component with an attachment bracket includes an upper isolation member; an upper isolation member retainer which captures the upper isolation member axially between the upper isolation member and the attachment bracket; a lower isolation member; a lower isolation member retainer which captures the lower isolation member axially between the lower isolation member the attachment bracket; and a retention member extending from the lower isolation member and having a retention member first end and a retention member second end such that the retention member first end is fixed to the lower isolation member retainer and such that the upper isolation member retainer is captured axially between the attachment bracket and the retention member second end.

A holder for fastening at least one component, particularly a fuel distributor, to an internal combustion engine. The holder includes an elastically deformable damping element, a holder body and a spring element, which are situated lying one behind the other with reference to an axis. In response to an assembly using the fastening arrangement, a prestressing of the spring element and a prestressing of the damping element are made possible. Furthermore, a fuel injection system is described having a fuel distributor and such a holder, which is used for fastening the fuel distributor on an internal combustion engine.

Low-cost fuel injection systems for internal combustion engines, including vapor fuel engines are provided.

A holding device is used for fastening a fuel distributor to an internal combustion engine. A plurality of holding elements is provided, which are able to be fixed in place on the internal combustion engine via a fastener. A cable guide is provided in addition. The holding elements are connected to the cable guide. In addition, a system having such a holding device and a fuel distributor for conveying fuel are provided.

A holder used for mounting at least one component on an add-on structure, e.g., an internal combustion engine, includes: a base element able to be connected to a component; a fixation element, which extends through the through bore of the base element and a damping element disposed in the through bore, in order to mount the base element on the add-on structure; a fixation sleeve; and a damping element surrounding an outer side of the fixation sleeve and form-fittingly connected to the fixation sleeve on at least one side along the longitudinal axis, and on at least one side the damping element is form-fittingly connected to the base element along the longitudinal axis.

An electronic fuel injection throttle body unit has a core body with two side components. The two side components each including a fuel delivery passage. Four air intake passages extending vertically through the throttle body. Valves are rotatable within the air intake passages. The valves being connected to valve shafts that rotate about respective valve shaft axes. The valve shaft axes and the fuel delivery passages are perpendicular to each other.

A multipoint fuel injection system comprises an injection system segment including a circumferentially extending outer support defining a fuel manifold with a plurality of manifold passages extending circumferentially therethrough. A first connector is included at a first circumferential end of the outer support and a second connector is included at a second circumferential end of the outer support opposite the first circumferential end. The first and second connectors are each configured to connect each manifold passage with a manifold passages of a respective outer support of a circumferentially adjacent injection system segment. The system includes a circumferentially extending inner support and a plurality of circumferentially spaced apart feed arms extending radially between the inner support and the outer support. A plurality of outlet openings extend in an axial direction from each feed arm for feeding respective injection nozzles.

A holder for attachment of a component, in particular a fuel distributor, to an internal combustion engine includes: at least one decoupling element, an attachment body, an attachment element, and a holding element. The attachment body is attached to the internal combustion engine by way of the attachment element. The holding element is attached to the attachment body via the decoupling element. The decoupling element is shaped in such a way that in at least one spatial direction, a nonlinear spring characteristic curve, which describes a correlation of a return force acting on the holding element with a deflection of the holding element relative to the attachment body, is predefined.
