PRODUCT QUESTIONS产品问答
Product & customization questions产品与定制常见问题
Is an engine harness a universal product?发动机线束是通用产品吗？
No. It is a broad family of on-engine, injector, ignition, sensor, aftertreatment, transmission and body-interface assemblies. Engine, controller, emissions equipment, vehicle configuration and route determine the released version.不是。它是发动机本体、喷油、点火、传感、后处理、变速箱及车身接口组件组成的广泛家族，发动机、控制器、排放设备、车辆配置与走线共同决定放行版本。
Can a matching connector prove that two engine harnesses are compatible?连接器能插合就能证明两根发动机线束兼容吗？
No. Keying does not prove pin assignment, terminal rating, cylinder order, reference ground, shielding, communication, load current or controller compatibility. These must be verified against the actual system.不能。防错不能证明针脚定义、端子额定值、气缸顺序、参考接地、屏蔽、通信、负载电流或控制器兼容性，必须结合真实系统核对。
Can you build gasoline, diesel and industrial engine harnesses?可以制作汽油机、柴油机和工业发动机线束吗？
Yes, when the engine, controller, circuit information, interfaces, environment and validation requirements are defined. Each project is reviewed for its actual fuel system, ignition or injection, aftertreatment, voltage and equipment duty.可以，但需要明确发动机、控制器、回路信息、接口、环境和验证要求。每个项目都按真实燃油系统、点火或喷射、后处理、电压与设备任务审核。
