丰田车系中的皇冠3.0(2JZ-GE型发动机)轿车和1993年1月后生产的凌志LS 400轿车,电动汽油泵控制电路类同,都是采用多工况变速控制电路。控制电动汽油泵工作的不是常见的电感式继电器,也不是电感式双速继电器(12V和8V电压转换),而是多工况变电压控制器。为此,称其为电动汽油泵ECU。1 多工况变速电动汽油泵控制电路的控制过程丰田皇冠3.0轿车2JZ-GE型发动机的电动汽油泵控制电路,如图1所示。
The Crown 3.0 (2JZ-GE engine) sedan in the Toyota car line is similar to the Lexus LS 400 sedan and electric gasoline pump control circuit produced after January 1993. They all adopt the multi-speed control circuit. Instead of inductive two-speed relays (12V and 8V voltage converters) that control the operation of electric gasoline pumps, they are not common inductive relays, but multi-mode variable voltage controllers. To this end, call it electric gasoline pump ECU. A multi-condition variable speed electric gasoline pump control circuit control process Toyota Crown 3.0 Sedan 2JZ-GE-type electric gasoline pump control circuit, shown in Figure 1.
