The biggest expense is usually on the fuel injector
The market for automotive fuel injectors
is growing at a CAGR of 4.
Within its CELECT fuel injector
, the company incorporated a metering plunger made from Mg-PSZ, a re-engineered magnesia with partially-stabilized zirconia specifically tailored for the application.
Currently fuel injectors
are designed after lengthy optimization trials, partly because today's fuel injectors
have complex geometries that challenge conventional wisdom on how these injectors work.
If the "Check Engine" light is illuminated, it may mean a problem with the fuel injectors
or oxygen sensors.
Case in point: Fuel injectors
and anti-lock braking systems, where fluid pressures are so high they actually deflect metal a little bit.
On the practical side, Moseler and Landman predict that nanojets may make possible tiny fuel injectors
whose smaller, more uniform droplets would burn cleaner in engines.
And ethanol forces mechanics to replace fuel injectors
every 3,000 to 5,000 miles, at a cost of about $4,500 each time.
According to Dave DiBerto, Global Fuels Business Manager for Afton, "DIG engines can be prone to performance-robbing deposits that form in fuel injectors
Although there are things that Kobenschmidt Pierburg doesn't produce for an engine, like crankshafts and fuel injectors
, if has a sufficient range of capability, know-how, and experience in other engine-related products such that it isn't hard to imagine that the company could become a complete low-volume specialist engine manufacturer.
A good burn depends on thorough mixing of air and fuel, though, and fuel injectors
allow little time for mixing before combustion.
