这是站在车站边缘的单个泵。似乎没有人使用它。孤独的岛屿空缺，直到您听到卡车的隆隆声为止。一辆送货卡车噪音噪音转移到车站地段，并拉到泵上。您没有注意到的是高效的紧凑型汽车，它偷偷溜到泵的另一侧。柴油不再只是卡车。
柴油发动机在运输行业具有使用史。它们为其尺寸产生大量的扭矩，并在重载下可靠。但是，在运输卡车中如此突出的技术已经被缩减为皮卡车和紧凑型汽车，其效果很好，而且受欢迎程度也在增长。
什么是柴油燃料？
柴油燃料是一个广泛的术语。它指的是一种在压缩下点燃而不是被火花点火的燃料，称为燃料点火。它最常见的是原油（如汽油），但经过不同的部分精炼程序。这使柴油燃料比汽油更具石油性能。
Alternate sources of diesel fuel have been developed, such as bio-diesel that can be made from vegetable oil. Diesel fuel is extremely stable to store and make, and home kits are made to create your own bio-diesel.
柴油发动机的工作方式
A diesel engine is significantly different from a gasoline engine. The premise is the same, where a small explosion inside an engine’s cylinder propels the piston downward, creating a power stroke. How it’s achieved, however, is astoundingly dissimilar.
尽管火花塞点燃了汽油发动机中的爆炸，但根本没有点燃柴油发动机。它们不配备火花塞，而是仅依靠压缩。在汽油发动机中，压缩比通常从8：1到10：1，这意味着气缸中的空气和燃料的体积被压缩到其原始体积的十分之一到十分之一。在柴油发动机中，这种压缩大约翻了一番！柴油燃料和空气混合物从14：1到22：1被压缩。
Why does this matter? It’s because the explosion happens simply due to the extreme pressure of that compression on the fuel. Diesel fuel doesn’t burn well when exposed to spark or flame anyway, but produces vast amounts of power when it explodes due to compression.
Fuel injection
由于其较厚和油性的稠度，柴油燃料更难雾化并喷入气缸中。同样，在压缩的最高点注入柴油燃料。这意味着柴油发动机的喷射系统需要令人难以置信的压力才能有效地将燃料注入气缸中。柴油发动机通常运行两个燃油泵；从水箱到发动机舱的供应泵，以及高压注入泵，以增加喷油器的压力。
Benefits of modern diesel technology
New technology on the market, including common rail diesel (CRD) injection systems and diesel particulate filters, mean that diesel engines run quieter and cleaner than ever before. The offensive smell and loud operation that made owning a diesel unpleasant has been negated, and the fuel efficient benefit has increased its popularity once again.
Potential diesel fuel issues
拥有柴油发动机的车辆可能会带来自己的一系列常见问题。当在寒冷，零下的气候下运行时，柴油燃料往往会凝胶，从而引起重大的起始和运行问题。它很容易被柴油燃料护发素纠正和纠正，但仍然很烦人。由于柴油发动机并不像汽油那样受欢迎，因此找到一个配备有柴油燃料的乘用车的加油站有时是一个挑战。请注意附近的位置及其小时，并计划在乘坐公路旅行时停止前进。
柴油发动机的常见问题
Water doesn’t combust very well. When diesel fuel contains water vapor, it can significantly affect its operation. Diesel engines are equipped with a filter called a fuel-water separator that needs regular servicing and is commonly neglected. Diesel engines can be quite costly to repair because they are labor intensive to diagnose and repair. An example of a common problem across many manufacturers is the cylinder head gasket: it is susceptible to premature failure because it seals the highest compression point in the engine.汽车服务公司的定期维护，例如Mymechanic万博体育入口，除了在出现时诊断出问题，还将有助于避免不必要的维修费用。
