- 第一章 柴油机使用说明 Operation Description 1.1 WP12系列柴油机型号含义 Signification of WP12 Series Diesel Engine Type Code 1.2 新柴油机使用须知 Operating Notice for New Diesel Engine ◆新柴油机在使用的最初 60 小时 （或 3000 公里） 内应限制柴油机的负荷不应超过标定负荷 的 75% Within the first 60 hours (or 3,000 km), the load of new diesel engine shall not exceed 75% of the rated load. ◆首次换油期的规定 Provision of the first oil replacement period 对于年行驶里程不到 2 万公里的汽车， 首次换油期：1000 ～ 1500 公里； For the vehicle with running mileage less than 20,000 km per year, the first oil replacement period is 1,000~1500 km; 对于年行驶里程超过 2 万公里的汽车， 首次换油期：1500 ～ 2000 公里。
For the vehicle with running mileage more than 20,000 km per year, the first oil replacement period is 1,500~2000 km; ◆按使用说明书的相关规定进行日常的维护与保养 The daily maintenance are done in accordance with the relating provisions in Operation Manual. 1.3 柴油机的启封 Unseal of Diesel Engine 当柴油机包装箱打开以后， 用户首先按出厂装箱清单清点柴油机及其附件， 检查柴油机外表 有无损伤， 连接件是否松动等， 然后再进行下述工作： Upon opening of the packing box, the user shall check up the diesel engine and accessories therein according to the Ex-work Packing List, and check the diesel engine for damaged surface or loose connecting fittings, and then execute the following: W P XX YYY 机型号(MODEL) 排量(DISPLACEMENT) 动力(POWER) 潍柴(WEICHAI) 蓝擎WP12国Ⅲ系列柴油机维修手册 -- Maintenance Manual for Landking WP12 Euro Ⅲ Series Diesel Engine ◆擦拭外露件的防锈层， 以及防蚀剂等； Wipe the anticorrosive layer and anticorrosive agent off the exposed parts; ◆放出燃油滤清器以及燃油系统零部件内部的油封油 （也允许燃油系统的油封油不经放出而 启动， 但必须只有当燃油系统的油封油被消耗完， 正常柴油已供应到才允许发动机加负荷运行） 。
但用户注意， 柴油机的油封期为一年， 凡超过 1 年的应进行检查并采取必要的补充措施 Drain off the seal oil in from fuel filter and the parts and components of fuel system (It may be allowed to start the engine without draining off the seal oil in fuel system. Provided the seal oil in fuel system is exhausted and normal fuel is supplied for use, it is allowed to run the engine with load.). But the user shall notice that the oil seal period is one year, inspection and necessary actions should be taken if the period exceeds one year. ◆转动飞轮并向进气管内喷溶剂， 直到驱尽气缸内油封油为止。
Rotate the flywheel and spray solvent to the air inlet pipe till seal oil in cylinder is exhausted. ◆向增压器进排气孔喷溶剂， 直到驱尽油封油为止 Spray the solvent to the outlet and inlet of supercharger till seal oil is exhausted. ◆根据厂方与用户的协约， 对油底内未注油的应按规定加油；对油底出厂时已注满含有磨合 促进剂的机油时建议用户行驶 2000km （或运行 50 小时） 后放出旧油换新油 With reference to the agreement between the manufacturer and the user, in case of the sump without oil, oil should be added as per the regulation; and in case of the sump with full oil for run-in, the old oil should be replaced with new one after having traveling 2000km (or running 50h). ◆ 按厂方与用户的协议， 出厂时如根据用户需要， 已加注满冷却液的， 启封时应检查冷却液 性能， 如果防冻能力是满足 -30 或 -35 的， 其 PH 值为 7~8 （中性） ， 总硬度值为 5~15° d [9~15° f( 硬度 )]， 则可以使用这些冷却液， 如果不合乎要求， 则应放出， 重新加注含防冻添加剂的冷却液。
With reference to the agreement between the manufacturer and the user, if the engine has been filled with coolant fully as required by the user, inspect the performance of coolant when unsealing. Provided that its antifreeze capacity meets -30℃ or -35℃ , PH value is 7~8 (neutral), and the total hardness is 5~15° d ［9~15° f(hardness)］ , those coolant can be used. Or the coolant, if unsatisfactory, should be drained off and replaced with the coolant with antifreeze additive. 1.4 起动前的准备工作 Preparation before Starting ◆ 检查冷却液面 Inspect coolant level -- 蓝擎WP12国Ⅲ系列柴油机维修手册 Maintenance Manual for Landking WP12 Euro Ⅲ Series Diesel Engine 如果发动机已装在汽车上或者台架上， 任何时候都能通过膨胀水箱上的玻璃视孔看到冷却 液面， 如冷却液不够时， 可打开加液口盖加入冷却液。
在打开带有卸压阀和排气按钮的加液口盖 时， 如果发动机处于热状态， 要打开盖子就必须先按下排气按钮 切忌在发动机处于较热状态时 往里加入大量冷却液而因为冷热变化大而损害零件 如果在非常情况下没有冷却液， 允许缓缓加 入温度不太低的冷水， 从加液口加入冷却液直到溢出为止 起动发动机在发动机运转情况下 （1000 r/min） 继续将冷却液加满直到液面稳定， 最后盖上加液口盖 In case that the engine is installed on vehicle or engine bed, the coolant level can be observed from the glass observation hole on expansion tank at any time. If the coolant is inadequate, open the filler cap and fill coolant. When opening the filler cap with pressure relief valve and exhausting button, if the engine is in hot state, press the exhausting button before opening the cap. It is forbidden to fill plenty of coolant, when the engine is still in relatively hot state, in order to prevent the parts from the damage due to sudden temperature change. If there is no coolant in some abnormal case, it is allowed to slowly fill cold water at not very low temperature. The coolant should be filled from the filler till the coolant overflows. Start the engine and continue to fill coolant till its level is stable with engine running at speed of 1,000r/min, and finally cover the filler cap. ◆检查燃油液面 Inspect fuel level 如果发动机已装在汽车上， 应打开电源开关， 从燃油表上检查燃油液面或者检查燃油箱。
In case that engine is installed on vehicle, turn on the power switch, and inspect the fuel level from fuel gauge or check the fuel tank. ◆ 检查发动机机油液面 Inspect oil level 机油液面应在油尺的上、 下刻度线之间， 必要时从机油加注口添加机油 The oil level shall be located between the upper and lower graduation lines, and fill oil from the filler when necessary. ◆ 检查柴油机各种附件的连接是否可靠， 并排。
