Direct Injection systems have become popular in these days. However, Port fuel injection systems are still used on many cars. This video will show you the difference between them. Let's figure this out.
Reliability, not power or economy, is the most desirable attribute in a good engine. The benefits of any one fuel system are pointless if the engine is not reliable, or worse, if it needs to be replaced before the end of its useful life. There are 2 cars in my garage. One has port injection, and the other has multi-port injection (PFI + DFI). I would be wary of buying a car with a DFI engine only. A DFI engine will not be more economical or produce more power if the valves are caked with carbon deposits. If the injectors are damaged in a DFI engine, fuel can dribble into the combustion chamber (rather than being sprayed), resulting in uneven combustion, fuel dilution of the engine oil, and excess wear of the cylinder walls.

I totally agree with you about reliability. If an engine won't work, you cannot even enjoy having a car. Every car maker should put reliability first I think.
