[DML] Re: Understanding Fuel Injection

["content22207" <brobertson@xxxxxxxxxxxx>]

Problem may not be "understanding" fuel injection. There are certain
advantages of carburation that can make it desirable over injection
irrespective of knowledge:
- One central point of fuel metering vs individual ones (each cylinder
is always guaranteed to receive an identical fuel/air mixture, ring
and valve health permitting). Note that some carb'd manifolds are at
least dual plane, and some injection in fact shares a common throttle
body.
- Fewer components to buy and maintain. Those in common (filters,
hoses, etc) cost significantly less.
- Much better engine access (true of all carb'd vs injected versions
of the same block).
- Carburetors do wear out, but they rarely fail catastrophically
(except for the imfamous Holly "Power Valve"). Same for low PSI fuel
pumps that feed them. You can limp for thousands of miles on dying
components.
- Carburetors are much less sensitive to contaminants in the fuel system.
- I think the fire risk is lower due to lower fuel system pressures.

For some people these are more important than any performance
advantages of fuel injection.
