摘要： A method for controlling fuel injection in a multifuel internal-combustion engine (1) that can inject alternatively a liquid fuel and a gaseous fuel; the control method envisages the steps of: injecting the gaseous fuel by means of at least one corresponding injector (15); cyclically measuring the pressure (P rail ) of the gaseous fuel within the common channel (22); determining at least one upper-limit threshold (P rail-min ; P rail-max ) for the pressure (P rail ) of the gaseous fuel within the common channel (22); comparing the pressure (P rail ) of the gaseous fuel within the common channel (22) with the upper-limit threshold (P rail-min ; P rail-max ); and carrying out an automatic fuel switch from the gaseous fuel to the liquid fuel when the pressure (P rail ) of the gaseous fuel within the common channel (22) exceeds the upper-limit threshold (P rail-min ; Prail-max).

摘要： The invention relates to a device and a method to control fuel injection in a vehicle. The ECU (100) receives a set of engine parameters (103) and a pressure signal (104) to control a set of fuel injectors (104 to 107). The ECU (100) computes the amount of fuel required for each cylinder for one combustion. The amount of fuel required is computed based on the engine parameters (103). The ECU (100) also computes the maximum available time for the injection, the number of fuel injectors needed to be opened to inject the required amount of fuel and the durations of their openings. The ECU (100) opens the required number of fuel injectors (104 to 107) accordingly. The fuel injectors (104 to 107) inject the required amount of fuel in the intake manifold (110) of the engine where the fuel gets mixed with the air. The air-fuel mixture is delivered to the cylinders as explained previously. The ECU (100) operates the fuel injectors (104 to 107) in such a way that at least one of the fuel injectors is opened for a much longer duration than at least one other fuel injector. This will bring down the number of openings and closings of a fuel injector and increases the life of the fuel injectors (104 to 107).
摘要翻译：本发明涉及一种控制车辆燃料喷射的装置和方法。 ECU（100）接收一组发动机参数（103）和压力信号（104）以控制一组燃料喷射器（104至107）。 ECU（100）计算用于一次燃烧的每个气缸所需的燃料量。所需的燃料量基于发动机参数（103）计算。 ECU（100）还计算喷射的最大可用时间，需要打开的燃料喷射器的数量以喷射所需量的燃料和其开口的持续时间。 ECU（100）相应地打开所需数量的燃料喷射器（104〜107）。燃料喷射器（104至107）将燃料与空气混合的发动机的进气歧管（110）中的所需量的燃料喷射。如前所述，空气 - 燃料混合物被输送到气缸。 ECU（100）以这样的方式操作燃料喷射器（104至107），使得至少一个燃料喷射器比至少一个其它燃料喷射器打开更长的持续时间。这将减少燃料喷射器的开口和关闭的数量，并且增加燃料喷射器（104至107）的寿命。

摘要： Injector assembly comprising two or more injectors. Each injector comprises a housing with an inlet side and an outlet side and a delivery duct. The housing is designed to accommodate an electrical metering valve. According to the invention, each housing is provided with coupling means, such as engagement projections or lips for connection with another housing. Such a connection is preferably realized by pushing two injectors against one another and rotating them. In this manner, an injector assembly consisting of a number of injectors can be constructed in a simple and inexpensive way, depending on the required number. A safety shut-off valve can also be provided with the same coupling. According to a particular embodiment, flexible line means are also present which extend from the delivery duct of the injectors to, for example, an inlet manifold of a combustion engine.
