Abstract:
A combined ignition and fuel supply system for an internal combustion engine is described. The system comprises an ignition unit and a blending/dosing device (10) comprising a valve and equipped with an entrance duct (12) for the combustive agent, usually air, an entrance duct (14) for the fuel and an exit duct (16) for the fuel-combustive agent blend. The exit duct (16) is hydraulically connected to an aspiration manifold (18) which introduces the fuel-combustive agent blend into the cylinder (20) of the engine. Downstream of the valve of the blending/dosing device (10) and upstream of the cylinder (20), there is at least one pressure sensor (22) used to identify the pressure value of the fuel-combustive agent blend inside the aspiration manifold (18), in order to optimise fuel consumption and/or improve performance, varying the advance in relation to the pressure value in the aspiration manifold (18) and the engine revs.
Abstract:
The present invention relates to an arrangement and a method for estimating a fuel mixture's content of a supplementary fuel. A combustion engine (1) is provided with a so-called common rail system with a high-pressure pump (6) and an accumulator tank (7) for storage of the fuel mixture before it is injected into the engine (1). The arrangement comprises a control unit (9) adapted to determining the pressure change (Δρ) in an accumulator tank (7) within a period of time (Δt) on the basis of pressure values from a pressure sensor (7a), to providing information about a corresponding pressure change (Δρ 0 ) on a reference mixture with a known content of the supplementary fuel within a corresponding period of time (Δt) and to estimating the fuel mixture's content of the supplementary fuel by comparing the pressure change (Δρ) on the fuel mixture with the pressure change (Δρ 0 ) on the reference mixture. Conducting said estimation in operating situations where the high-pressure pump (6) pressurises a maximum volume of the fuel mixture while at the same time no fuel is injected into the engine results in estimation with very good accuracy.
Abstract:
The present disclosure is directed to a fuel circuit (500) of a fuel injector (12) that includes a first channel, a second channel, and a valve (80). The first channel is configured to receive a first fuel and define a flow path for the first fuel. The second channel is configured to receive a second fuel and define a flow path for the second fuel. The valve (80) is in fluid communication with the first channel and the second channel. The valve (80) is adapted to direct the second fuel to the first channel when a pressure in the first channel reaches a predetermined level.

The invention provides for a vehicle fuel tank arrangement for a fuel comprising at least a first fluid (5) and a second fluid (6), the tank arrangement (11) comprising: - a tank (12); - a partition wall (13) arranged inside the tank (12) in order to create at least a first compartment (14) for storing the first fluid (5) and a second compartment (15) for storing the second fluid (6); characterized in that the position of the partition wall (13) inside the tank (12) can be changed to set the volume of the first compartment (14), respectively the second compartment (15), to a predetermined value
Abstract:
At least one donor cylinder (28) is coupled to an intake manifold. The intake manifold (16) is configured to feed a mixture of air and a first fuel, or a mixture of air, the first fuel, and a second fuel to the at least one donor cylinder. At least one non-donor cylinder (30) is coupled to the intake manifold (16) and an exhaust manifold (18). The intake manifold (16) is further configured to feed air, or a mixture of air and the second fuel to the at least one non-donor cylinder (30). An exhaust channel (36) extend from the at least one donor cylinder (28) to the intake manifold (16) for recirculating an exhaust emission from the at least one donor cylinder (28) to the at least one donor (28), and non-donor cylinders (30) via the intake manifold (16).

Abstract:
A unitary assembly for retaining the various components of a fuel control system on a vehicle, wherein the assembly includes a unitary module at least partially structured in the form of a mounting assembly operative to contain and support at least a portion of the fuel control system specifically including a containment structure or at least one fuel tank for storing and operatively disposing a fuel supply associated with the fuel control system. An electronic control unit of the fuel control system is structured to facilitate metering and distribution of an operative fuel mixture which may include an alternate fuel as well as a conventional distillate fuel. The module and the mounting assembly are cooperatively structured to collectively retain the electronic control unit, the containment structure and at least a portion of a remainder of the fuel control system as a self- contained unit on the vehicle.
