Abstract
A fuel supply apparatus for an internal combustion engine includes a first fuel injector provided for each cylinder of the engine for injecting fuel into an intake pipe of the engine. A second fuel injector is disposed at a location upstream of the first fuel injector for injecting fuel into the intake pipe independently of the first fuel injector. A heater in the form of an electric heating plate is disposed on the inner surface of the intake pipe at a location between the first and second fuel injectors for heating and evaporating the fuel injected from the second fuel injector.

A fuel supply apparatus for an internal combustion engine comprising:
- a first fuel injector provided for each cylinder of said engine for injecting fuel into an intake pipe of said engine;
- a second fuel injector disposed at a location upstream of said first fuel injector for injecting fuel into said intake pipe independently of said first fuel injector;
- and
- a heater disposed on the inner surface of said intake pipe at a location between said first and second fuel injectors for heating and evaporating the fuel injected from said second fuel injector.
A fuel supply apparatus for an internal combustion engine having a plurality of groups of cylinders, said fuel supply apparatus comprising:
- a plurality of first fuel injectors provided one for each of said cylinders for injecting fuel into an intake pipe of said engine connected with said cylinders;
- a plurality of second fuel injectors provided one for each group of said cylinders and disposed each at a location upstream of a corresponding group of first fuel injectors for injecting fuel into said intake pipe independently of said first fuel injectors;
- and
- a plurality of heaters provided one for each second fuel injector and each disposed on the inner surface of said intake pipe at a location between a corresponding second fuel injector and a corresponding group of first fuel injectors for heating and evaporating the fuel injected from said corresponding second fuel injector.
