DOHC 的音标是/"dəʊhɔːk/,意思是“顶置凸轮轴”。在记牢这个单词时,可以尝试以下技巧:
1. 拆分单词:DOHC可以被拆分为“DO”和“HC”两个部分。DO通常代表“顶杆”(也称为顶杆组件),而HC可能是指一种材料或工艺,但在这里它显然是指顶置凸轮轴的结构。
2. 关联概念:凸轮轴是一种驱动进气或排气门开闭的机械装置,而顶置凸轮轴则将其置于气缸盖顶部,因此得名。
3. 多次重复:多次重复是任何单词记忆的基础技巧,需要多次尝试和练习。
总的来说,通过将DOHC拆分为两个部分,并与相关概念关联,再加上多次重复,应该可以帮助你更好地记住这个单词。
DOHC(直列双凸轮轴)这个词的英文词源是"direct over head camshaft",意为凸轮轴直接安装在发动机气缸盖上。这个词是由两个英文单词组合而成的。"direct"表示"直接的","over head"表示"在头顶上方",而"camshaft"则表示"凸轮轴"。
变化形式:在书写和口语中,DOHC通常被简化为DOHC。
相关单词:
SOHC(直列顶置凸轮轴) - 意为凸轮轴直接安装在发动机气缸盖上,但与DOHC不同的是,凸轮轴的位置不在头顶上方。
I-VTEC(智能可变气门正时和升程电子控制系统) - 这是一个用于控制发动机气门正时和升程的系统,通常与DOHC技术一起使用。
L-Jetronic(轻型Jet发动机电子燃油喷射系统) - 这是宝马汽车公司的一种燃油喷射系统,通常用于小型发动机,它与DOHC技术没有直接关系。
DOHC执行器 - 一种用于控制DOHC系统中的凸轮轴运动的电子或液压驱动器。
DOHC效率 - 描述DOHC技术带来的发动机性能和效率的提升。
DOHC故障 - 描述由于DOHC系统故障导致的发动机问题。
DOHC调整 - 描述对DOHC系统中的凸轮轴位置、角度或运动进行的调整。
DOHC活塞环 - 描述用于密封气缸并传递动力到曲轴的活塞环,在DOHC发动机中可能更加重要。
DOHC效率优化 - 描述如何通过设计和调整来优化DOHC发动机的效率。
以上这些单词都与DOHC技术有关,并且可以用来描述和解释DOHC的相关概念和特性。
