12V240ZJ6F型柴油机1 柴油机工作原理当活塞由上向下运动时,外界的新鲜空气经过进气门被吸入气缸,而后活塞向上运动,对这部分新鲜空气进行压缩,使空气的温度和压力都有较大的升高。
这样的空气与从喷油器喷入气缸的柴油混合,能使柴油自行着火燃烧放出热能,此时燃气温度和压力急剧升高,而后急剧膨胀,推动活塞向下运动做功,经过连杆、曲轴输出扭矩。
柴油机的一个完整的工作过程是由进气、压缩、燃烧膨胀、排气四个冲程组成,即曲轴旋转两圈、活塞经过四个冲程。
1.2.1 进气冲程:在配气机构的作用下,进气门在活塞处于上止点前42º20’曲轴转角时开启,新鲜空气通过增压并冷却后,经稳压箱、进气支管、气缸盖进气道进入气缸内,当活塞运动到下止点后42º20’曲轴转角时,进气门关闭。
1.2.2 压缩冲程:当气门完全关闭时,活塞继续上行,压缩过程开始,随着活塞上行,气缸内的空气不断被压缩,其压力和温度不断升高,为柴油自燃创造了必要的条件。
当活塞到达上止点前21º时,柴油以雾状喷入燃烧室,与气缸内的高压高温的空气混合。
1.2.3 燃烧膨胀冲程:当喷入气缸内的柴油与高温高压空气混合后迅速燃烧,开始了燃烧过程,燃烧压力急骤上升,燃气最高温度可达1500℃。
1.2.4 排气冲程:当活塞到达下止点前42º20‘曲轴转角,排气门开启,开始了排气过程,这时气缸内经过膨胀做功的燃气开始排出,活塞经过下止点继续上行,直到活塞再次达到上止点后42º20‘曲轴转角,排气门完全关闭为止。
2 柴油机简要介绍2.1 柴油机总体结构12V240ZJ6F型柴油机为四冲程、V型、废气涡轮脉冲式增压、增压空气中间冷却、开式燃烧室的中速柴油机。
柴油机两排气缸V型排列,V型夹角为50°,活塞连杆装在气缸套内,连接在曲轴的曲柄销上,每个缸有六条气缸螺栓将气缸盖紧固在机体上。
柴油机曲轴输出端通过联轴节与主发电机的转子相连进行功率输出,机体的输出端通过连接箱与主发电机的定子连接。
柴油机基础知识第一章柴油机基础知识第一节柴油机概述内燃机是一种复杂的能量转换机器。
随着技术水平的不断提高,各种类型内燃机的构造及其布置也就各有差异。
往复活塞式内燃机的基本构造,都由下列二个机构和五个系统所组成。
以柴油作燃料,当空气在气缸内受压缩而产生高温,使喷入的柴油自然,燃气膨胀而作功的内燃机,称为柴油机。
我国现生产柴油机的功率覆盖面为2.2—47280KW,柴油机的气缸直径65—900mm,转速5.6—4400r/min。
特点:易于起动、操作维护方便、结构紧凑、体积小、重量轻、便于运输安装、经济性好、使用范围广,是较理想的动力机械,广泛用作发电、船舶、排灌、汽车、拖拉机和工程机械等动力。
第二节柴油机分类按照工作循环分类:二冲程柴油机和四冲程柴油机;按照气缸数量分类:单缸柴油机和多缸柴油机;按照汽缸排列方式分类:立式、卧式、直列式、斜置式、V形、X形、W形、对置汽缸、对置活塞等;按照冷却方式分类:水冷柴油机和风冷柴油机;按照进气方式分类:自然吸气式和增压式;增压式可分为:低增压、中增压、高增压和超高增压等;按照曲轴转速分类:高速机、中速机、低速机;按照用途分类:固定式、移动式;第三节柴油机工作原理按照一定规律,不断地将柴油和空气送入气缸,柴油在气缸内着火燃烧,放出热能,高温高压的燃气推动活塞作功,将热能转化成机械能。
四冲程柴油机的正常运转通过以下四个工作过程来完成;进气过程: 活塞由上止点移动到下止点,即曲轴的曲柄内0°转到180°(活塞位于第一冲程上止点时,曲轴的曲柄位置定为0°)。
在这个冲程中,进气门打开,新鲜空气被吸入气缸。
压缩过程: 活塞由下止点移动到上止点,即曲柄由180°转到360°。
在这个冲程中,气缸内的气体被压缩;燃烧膨胀过程(工作过程): 活塞再由上止点移动到下止点,即曲柄由360°转到540°。
在这个冲程中燃气膨胀做功,所以又称为工作冲程或做功冲程。

1.1 低压燃油系统低压燃油系统组成集中式供油单元,为机器提供10~12bar 的燃料用油,包括:供应泵吸口双联滤器、供油泵及增压泵、带反冲洗功能的自清滤器、旁通滤器及相关部件。
1.2 共轨燃油与喷射系统(图2)在共轨喷射系统中,压力油由电子控制的高压油泵输出燃油至共轨蓄压器保压,电子驱动阀组用来决定燃油喷射的开始、连续及停止时间,而与柴油机的转速和喷射量无关。
图2 32/44CR 共轨系统概述对于系统建压,L32/44CR 共轨系统中没有独立机械油泵,只有通过柴油机凸轮驱动的高压油泵。
共轨高压油泵与传统机械控制式柴油机高压油泵不同之处在于没有齿条,通过高压油泵自带的由电子控制的节流阀实现单缸油量控制。
低压系统燃油经节流阀进入高压油泵后排入串联的共轨桶,通过高压油管可以将所有的共轨桶串联。
在共轨桶2端或1端装有阀组,通过安装在下部的1个单向溢流阀至低压系统,该单向溢流阀可以将喷油器喷射完成后的管内余压进行卸压,单缸燃油喷射的时间及油量可以通过电子控制阀组完成。
L32/44CR 柴油机燃油共轨系统简介盛卫明(中港疏浚有限公司,上海 200120)摘要:L32/44CR 柴油机是一款新型共轨电喷直立式四冲程柴油机,采用共轨式电子喷射系统,可对燃油喷射进行优化从而降低燃油消耗、减少氮氧化物排放。
控制系统采用曼恩自主研发的SaCoSone 系统,该系统集安全、监测和速度控制功能于一体,系统采用CAN 冗余总线方式与柴油机上控制单元进行通讯连接,完成信息交互。
现就该机型的燃油共轨系统和SaCoSone 控制系统进行简单介绍,使轮机管理人员加深对设备认识,增强管理经验,提升设备管理水平,保证船舶正常使用。

MAN V32/40系列柴油机包括18V32/40、16V32/40、14V32/40、12V32/40共4种机型,单缸功率为500kW,因此该系列柴油机的额定功率范围为6000~9000kW。
截止2011年底,国内已经有潍柴、陕柴、镇柴、杭州中高、石油济柴及南车资阳等公司获得了MAN V32/40柴油机的生产许可证。
这种状况无疑会加剧主机厂间的竞争,但是对曲轴制造业来说则是一种利好。
南车资阳公司2008年获得MAN V32/40系列柴油机生产许可证后,凭借雄厚的实力全力推进MAN机国产化。
2009年公司获得孟加拉电站项目,以18V32/40柴油机为主发电机,公司以孟加拉电站项目为载体开始强力推进18V32/40柴油机样机试制及核心零部件的国产化工作。
曲轴作为发动机的核心部件之一,是首批要求进行国产化的零部件。
