The fuel pumps for diesel engines are different from those of gasoline engines. Diesel engines run under much higher pressure than gasoline engines, which require a separate type of fuel pump to hold up against these particular requirements. To illustrate this, a common rail diesel injection system might work at greater than 30,000 psi of pressure while gasoline systems usually involve around 3,000 psi. The reason for the difference in pressure further explains why fuel pumps must differ mechanically, structurally and materially.
They are engineered for withstanding the higher compression rates of diesel engines. A fine case to consider is lethal vehicles, including diesel engines for maximum torque and fuel mileage. Manufacturers like Bosch (clearly associated with diesel fuel system innovation) build pumps that are made to work well moving the heavier, oily high-pressure side of one pump through a set of injectors as opposed gas which is quite light and not so terribly dense. Diesel-rated fuel pumps typically come with strengthened parts that allow it to last longer especially when exposed under harsher conditions commonly experienced by most diesel engines, such as the ones present in construction and logistics industries.
Diesel powerplants suffer greatly due to inaccurately matched fuel pumps which would lead more downtime and a higher-maintenance costs as diesel engines depend largely on the accuracy of their fuel delivery systems such reports claim. The flow rate and operating pressure for diesel mission-critical fuel pumps must be literally fine-tuned based on what the engine needs to avoid any potential damage or in-efficiency.
In addition, diesel fuel pumps are usually more expensive than those for gasoline. Some of this is due to the high tech applied in order to keep a higher pressure and strength required for diesel systems. The purchase of a quality diesel fuel pump, though it may result in higher total costs long term; can save you money on lower fuel mileage and fewer engine replacements.
Marc Bazner added, “As Henry Ford once said, ‘Quality means doing it right when no one is looking’ and particularly parts like fuel pumps must be built with precision for lasting wear.” Hence, to the question “Are fuel pumps of diesel different“, I need say a strong yes backed by informative is possible and unique demands especially on engines.
