附图说明
图1为现有乙醇燃料发动机加热方法的流程图；
图2为本发明实施例提供的乙醇燃料发动机的预热方法的流程图。
具体实施方式
下面结合附图和具体实施方式对本发明作进一步详细说明：
一种乙醇燃料发动机的预热方法，如图2所示，包括如下步骤：
首先，判断车钥匙是否插入到钥匙孔，若否，则启动遥控预热，该遥控预热包括下述步骤：
(1.1)预热信号发射装置发出预热请求信号；在本实施例中，优选地，所述预热信号发射装置为遥控钥匙，将遥控解锁的无线解锁信号作为预热请求信号，如此一来，可将汽车遥控开锁装置和预热信号发射装置合二为一，大大方便了驾驶员的操作。
(1.2)信号接收装置接收到所述步骤(1.1)中的预热请求信号；在本实施例中，优选地，所述信号接收装置为BCM(Body Control Module，汽车车身控制模块)，由于BCM呈现出模块化的趋势，所以，BCM可集成更多的功能，因此，BCM作为信号接收装置可使汽车电子控制系统更加简洁。
(1.3)BCM发送预热请求至发动机控制装置，在本实施例中，优选地，所述发动机控制装置为ECU(Electronic Control Unit，电子控制单元，汽车专用微机控制器，也叫汽车专用单片机)。
BCM与ECU可以通过CAN总线进行通讯，定义一个值为0或1的变量表征预热请求信号，ECU周期性的读取CAN上该信号值。当该值为1时，表示有预热请求；值为0时，无预热请求。
BCM与ECU也可以通过硬线进行通讯，定义预热请求信号的有效信号的电平值及持续时间，例如，可以定义预热请求信号为500ms的12V电平信号。
在本实施例中，BCM延迟一段时间(优选1秒钟)后发送预热请求至ECU。延迟的目的在于需要对信号进行一个判断，防止驾驶员误操作或无驾驶意图，通过延长一段时间，若在该延长期内BCM未收到遥控钥匙锁门 信号，则发送预热请求至ECU；若在延长期内收到遥控钥匙锁门信号，则不发送预热请求。
ECU接收到信号后判加热次数是否已达上限，在本实施例中设定加热次数的上限为3次，当加热次数达到上限次数3时，第4次加热请求时，ECU虽会被唤醒，但停止预热请求，不会进行加热。此时需采用钥匙档位唤醒模式才能启动加热功能，如此可有效保护电瓶，避免多次加热造成电瓶馈电后无法启动发动机。若未达上限，则执行步骤(1.4)。
(1.4)发动机控制装置判断是否满足预热条件，其中预热条件包括温度判断，若环境温度低于设定温度20℃，则允许加热，否则，则不允许加热。此外，预热条件还包括：燃料是否为E100乙醇燃料、ECU当前是否存有故障码、电平电压是否满足要求、是否允许遥控预热等。
若满足预热条件则启动加热装置进行加热且加热次数计数一次并将ECU中遥控预热状态标志位置位(该标志位已预先在ECU中设定)，当发动机成功启动后加热次数计数清零，所述遥控预热状态标志位清零，若不满足预热条件则不启动加热装置。
若车钥匙插入到钥匙孔内且档位为ON档，则启动钥匙档位预热，其步骤如下：
(2.1)发动机控制装置判断遥控预热状态标志位是否置位，若已置位，则可启动汽车，若未置位，则执行步骤(2.2)。
(2.2)发动机控制装置判断是否满足预热条件，其中预热条件与步骤(1.4)中的预热条件基本相同，但不用判断是否允许遥控预热，若满足预热条件则启动加热装置进行加热，若不满足预热条件则不启动加热装置。加热后，可启动发动机。
另外，加热装置在加热过程中，若监测到电瓶电量低至无法满足再一次预热发动机且使启动电机正常启动发动机的限值，则终止加热。从而，保证电量可以满足驾驶员进入车辆后通过档位预热并启动车辆，避免了由于驾驶员多次遥控预热后长时间不进入车辆，电瓶严重馈电导致车辆无法开动。
优选地，加热装置为加热型喷油器，如此，喷油器在接受ECU送来的 喷油脉冲信号前即可对乙醇燃料预热，在喷射前实现雾化。
该乙醇燃料发动机的预热方法通过预热信号发射装置发出预热请求信号，信号接收装置接收到所述预热请求信号，发动机控制装置对所述预热请求信号处理后，启动加热装置进行加热，从而能够在驾驶员进入车辆之前提前预热乙醇燃料发动机，进而实现发动机的快速启动，节约了驾驶员的等待时间，提升了驾驶的方便性和舒适性。
综上所述，本发明的内容并不局限在上述实施例中，本领域的技术人员可以根据本发明的指导思想轻易提出其它实施方式，这些实施方式都包括在本发明的范围之内。
