As a car nut, this actually seems pretty reasonable; if you take that diameter and divide it by (fuel injector duty cycle at cruise rpm, times number of injectors), the resulting diameter should be pretty close to the car's injector outlet effective diameter!

- valarauca1 11y agoHi, I actually work in fuel system analysis. The one issue with the blog post that nobody seems to realize or point out. Is that fuel consumption is measured, and calculated internally as kilograms per kilometer. The change to volumetric units is done for the benefit of the population. This comes into play because namely, thermal expansion. Normally even in return less engines fuel is used to cool injector heads, as well as some body block parts (depending on engine design), as hotter fuel more readily reacts, and is already being routed to the warmed parts of the engine.
- raldi 11y agoThat seems like a coincidence, that the relative velocity between the car and the fuel shooting through its injector should be approximately the same as the relative velocity between the car and the road. One could conceivably build a car with half-size injector nozzles that squirt in the same volume of fuel per unit time.
