Description

一种电子式进气调节装置及其系统
技术领域
本发明创造属于发动机技术领域,具体涉及发动机进气控制系统,特别是涉及一种适用于摩托车等小排量单杠或多缸发动机的节气门装置。
背景技术
近年来,随着内燃机行业对排放要求以及产品性能的要求不断提高,原有化油器系统已逐步电喷化。在现有电子燃油喷射系统中,必须的部件包括进气节气门装置、温度及压力传感器、电喷控制单元(ECU)等。
其中,进气节气门装置用于控制发动机进气流量,决定发动机的运行工况,是发动机系统中重要组成部件。目前通用(摩托车等)小型发动机,多数仍采用传统的机械连接方式的节气门体,通过油门拉线或者拉杆连接油门踏板和节气门体,油门拉线直接控制门板开度,这无论是从发动机性能还是安全性能角度来看,都是存在较大弊端的。
对于上述问题,最常用的解决方案为,将手动控制的机械式节气门装置直接替代为电子式节气门装置,这种电子式节气门装置一般由本体、外壳、传感器、步进电机等组成,各电子器件通过独立的接插件与电子控制单元(ECU)通讯,整车线路连接复杂,增加了使用风险以及维护成本。其改进方案为,将ECU集成至节气门装置上,此方案对装置整体设计要求高,提别是用于布置空间较小的摩托车等小排量发动机上,容易造成几何形状不规则,增加制造成本。
因而,介于当前技术水平,有必要对现有机械式节气门装置的电子化设计做进一步的改进和研究。
发明内容

所述位置传感器用于检测节气门阀位置状态,可以选择使用霍尔式位置传感器,通过检测门板转轴上的磁性元件获得门板开启角度,并转换成电信号输出。
所述调速器布置于节气门本体上,包括一个电机驱动模块,所述电机驱动模块将信号发送至电机,所述电机根据收到信号调整控制节气门阀开闭程度。
所述压盖固定于节气门本体,用于封装所述调速器,压盖通过螺栓或者卡扣方式安装于节气门本体上。所述霍尔式位置传感器和电机均布置于调速器一侧,满足结构设计的同时提高整体集成度,并且便于封装。
上述电子式进气调节装置,可应用于电子燃油喷射系统,所述电子燃油喷射系统包括进气管道、发动机、ECU控制单元、燃油供给系统以及电子油门装置,所述电子式进气调节装置安装于进气管道上,位于发动机上游。
对于上述带电子式进气调节装置的电子燃油喷射系统,包括主动式进气调节控制方法,所述控制方法包括如下步骤:
包括所述调速器接收预先存储的转速信号或者操作者给出的油门信号的步骤,
包括所述调速器根据需求信号计算节气门阀开度需求的步骤,
包括所述电机接收调速器驱动工作指令,将所述节气门阀调至目标开度的步骤,
包括车辆控制单元ECU从所述位置传感器获取节气门阀开启位置的步骤,
包括所述ECU控制单元根据节气门阀位置调整喷油量和点火角的步骤,以满足目标转速或者实际工况需求。
进一步,上述调速器可以通过检测角标信号,直接判定发动机当前工况,计算发动机转速。
上述电子式进气调节装置,利用电子式进气调节装置控制节气门阀,取消原有机械式结构控制节气门阀装置,提高系统控制精度及安全性,此外,通过部件自身改进,在不影响系统其它部件的同时,以较低的成本满足整车改进需求。
