If you’re a fan of performance cars at all, especially those coming out of Japan, then you’ve heard of Honda’s all-mighty VTEC. This is Honda’s main claim to fame. It’s the ace in the hole for their naturally aspirated four (and six) cylinder engines – although VTEC has also continued on turbocharged Honda engines like the currentType R Civic。VTEC can boost performance, increase efficiency and decrease emissions. Over the years Honda have used it to great effect for all three of these goals.
VTEC has also become part of Internet meme culture, spawning plenty of ‘VTEC Just Kicked In Yo’ memes over the years:
但是......什么是vtec，究竟是什么？它如何实现更好的性能？所有本田都有vtec？在本版汽车事实中，我们将回答这些问题。
Nearly every new Honda has some form of VTEC or another, but it wasn’t always like this. A little over 30 years ago, not a single Honda car had it. Originally reserved for performance models, Honda slowly implemented it into its entire range. Let’s dive into a bit of how VTEC works to learn more about what it does, which Hondas have it and why.

你就像你一样，因为我希望你成为
One of the biggest factors that determines an engine’s personality is its cam profile. And when I say personality, I don’t just mean how it drives. Does it stink? Is it loud and obnoxious? Does it have a lot of “thirst”? Is it lazy, or horrible to live with? The cam determines a lot of this, as well as its overall performance.
今天，我们谈论表现......继续前进。
图片这个。您已经获得了这种惊人的强大的发动机，可以将所有方式转移到9,000 rpm。这是一个爆炸宽敞的开放，将油门削减并将其缠绕在红线上。但是前面的亮点刚刚变红，你必须停下来。在空闲的发动机现在绊倒和摇晃，几乎不想在光线终于绿色时移动。
On the flip side, maybe you’ve got a smooth idling engine. It’s got some torque down low and decent midrange power. When you really get to open it up though, it falls on its face long before redline. Not exactly a joy to drive.
The two example engines I’ve described here are a little exaggerated, but this is to illustrate a point. Both suffer from the same problem: they are restricted to one cam profile. Physics dictates how air moves in and out of an engine at different RPMs, and what works great at low revs is usually not what works best for high revs. While the cam isn’t the only factor here, it does play a major role. Which brings me to…
VTEC Just Kicked In, Yo!
“可变气门定时和提升电子控制”是what VTEC officially stands for。想想“vtec”听起来很酷吗？我也是，显然，本田也是如此。VTEC简而言之是在驾驶时更换凸轮轮廓（以及通过扩展，发动机的个性）的方法。这就是它如何弥合高转速和低转速世界之间的差距，因此您可以拥有最好的两者。
凸轮控制阀门，VTEC均为操纵阀门正时，阀升，或两者，以最适合驾驶条件。阀门升降装置简单地指的是阀门在发动机圆筒的进气或排气行程期间打开的距离。当升高到低RPM时，更多的升力可以产生非常明显的差异。高电平，它效果奇迹，但下降它可能导致空气失去速度。同样，根据发动机速度，持续时间（阀门留下的长度）将具有效果。
改变电梯的能力是关于vtec的真正特别的。本田是第一个，多年来唯一的制造商来做这件事。
It’s surprisingly simple, too. In VTEC engines that change lift, each cylinder has three cam lobes for intake and three for exhaust. Two of these are the humdrum “normal” cam lobes that operate things at low RPM. While they’re in control, the middle lobe happily bounces along on a spring, not doing much else besides taking up space. Once the engine reaches “high RPM”, oil pressure locks a few pins and the middle lobe takes over. Now, this high lift lobe is running the whole show. It operates both valves that the other two lobes were managing before. The duration is also changed with this lobe, all in the name of high RPM power delivery. The result is a noticeable shove in the back as all the acceleration you felt like you were losing suddenly comes back, and with a vengeance.
自成立以来，VTEC一直是本田最佳性能引擎的主食。来自90年代的Halwowed类型R发动机是Prime示例。R型公民和Integra的发动机当时是真正的现代奇迹，四缸的“法拉利”。两者都向大约9,000 rpm达到约9,000 rpm，每升110马力。没有VTEC，街头友好NA汽车中的那种电力输出将是不可能的。
To put this into perspective, atwin turbo 300ZXonly makes 100 horsepower-per-liter. And that’s with two turbos! Corvettes from the same era made a paltry 52, and a Ferrari 348 made (I hope you’re sitting down) only 94…
然后有nsx-r v6。VTEC在本田V6的情况下有点不同，因为它们中的大多数仅在进气侧操作（但是一些较新的型号也使用废气）。所有相同的，VTEC也在这款发动机中发挥着繁重的作用。结合V6的自然更高的扭矩，并且护理进入NSX-R的手动平衡和蓝图的内部，该发动机实际上是为赛车建造的。
How To Tell If Your Honda Has VTEC
VTEC was originally introduced in the late 1980s (first on the Integra XS with the B16A engine – not theacura / honda nsxas many think). In the early days, it was more of a premium option reserved for high performance cars like the NSX or top spec variants of existing cars like the Civic or Integra. Less expensive models could have non-VTEC engines.
Over time, VTEC came to be included more widely across the Honda range (although on economy-focused and/or entry level models, VTEC was deployed differently to strike more of a balance between performance and economy, versus the more aggressive performance focus on “legendary” VTEC cars like the Integra and Civic Type R … don’t make the mistake of thinking that VTEC on a Honda Fit is as potent as that on anS2000）。
These days, I believe that all Honda models come with VTEC of some sorts.
到目前为止，我打赌你要问，“哇，我的本田有vtec吗？我该怎么说？“有一些可靠的方法来了解您是否有它。
也许最简单的方法是看看阀门盖或发动机封面的顶部，而本田已被众所周知，他已经骄傲地宣传了VTEC名称。然而，这并不总是准确。你永远不会知道是否有人的旋转阀盖，以及一些来自vtec的本田不要这么明显地宣传它。像Integra类型R或Prelude类型S这样的性能模型在广告vtec的存在方面更加明显，而更多的车辆（使用VTEC的MILDER“迭代”在可用日常业绩和经济之间实现了巨大的平衡）也更加谨慎。
Surefire方法可以更多地参与其中。你可以拉动阀门盖，看看你的凸轮，但这是一个可怕的工作。挖掘它是更容易的，看看你是否可以找到vtec执行器。这些通常会在气缸盖上的某处找到。如果您有一个使用经销商的旧模型，则VTEC执行器将在附近。较新的发动机，如K系列，在头部背面有这个执行器。J系列V6的滤油器有致动器，所以突破膝盖垫。
当一切都失败了,你可以看看你的VIN number. The eighth digit represents the engine your car came from the factory with. Pop your VIN into any decoder (this one works well) and it will tell you specifically what engine you have. From there, you can look up your engine and find out if it’s equipped with VTEC. This takes a bit of extra time/effort, but is a surefire way of telling if your Honda has VTEC without having to spend too much time prodding around under the bonnet.
Recap – Do All Hondas Have VTEC?
自成立以来，VTEC一直捕捉到世界各地的驾驶爱好者的心中。1989年，正如他们所说，Integra XSI是第一个拥有它，而且其余的是历史。您将在过去的20年中找到非Vtec本田的困难时间，但他们确实存在。您走的另外一步，您就越有可能找到非VTEC模型。例如，如果你回去看看之前几代本田思域, you can see that in the 1990s there were plenty of fifth generation Civics you could buy that didn’t have VTEC at all.
多年来，有更多的发展，不同版本的VTEC，他们都有良好的用途。并非所有都利用高RPM凸轮凸角，负责所谓的“vtec踢”，但都具有相同的普遍目标。他们的目标是最大限度地提高输出，效率和驾驶性。本田设法找到一种从小包装中获得疯狂力量的方法，仍然实现了巨大的燃油经济性。在一个电动机威胁要接管的世界里，你还能真正要求吗？
