CARB TYPE ENGINE VS FUEL INJECTED ENGINE [merged threads]

How much more fuel-efficient are EFI engines? In percentage, ball park figures.

Let's take for example the Corolla XL with 1.3 engine, versus the Vios with 1.3 engine.

Kinda hard to compare. Almost like apples and oranges. First, for the same displacement, the EFI engine will give you more power and yet be fuel efficient... it jsut depends on how you drive.

A carb engine can either be tuned for power or efficiency but hard to do both well, it will always be a compromise if you want both.

Comfort, heck, a new car is still much better.

IMHO, there are so many variables kaya mahirap mag generalize. Yung XE and Vios are generations apart as far as engine design is concerned so apples to oranges nga.
I think if you have lead foot syndrome, mas magastos ang EFI than carb. I'm guessing the fuel pump of EFI's are more powerful and the injectors effectively fuel discharge will be higher than a carb design.

Of course you can change injectors and jets/carbs but in general, yun ang hula ko.

Generally, EFI engines are more efficient than carb ones with the same displacement. The Vios 1.3 EFI with VVTi has been tested to be significantly more efficient than the 2E 1.3 engine of past Corolla XLs and XEs. It is believed that new technology progressively translates to engines with more performance but same efficiency, same performance but better efficiency, or even both.

so better to get the vios, if fuel efficiency ang concern rather than the xl/xe.

halos pareho ang presyo nila na brand new

more performance but same efficiency, same performance but better efficiency, or even both.

An engine that has a greater output for the same input is generally more efficient. I think the problem that plagues some manufacturers is how they mate underpowered engines into fairly heavy bodies.
