Abstract
The present invention relates to a supercharged internal-combustion, notably indirect-injection engine comprising at least one cylinder (10) with two types of supercharged air intake means (12, 14), one type for non-carbureted supercharged air intake (12) and another type for carbureted supercharged air intake (14), said intake means being supplied with supercharged air by supply means (38). According to the invention, supply means (38) comprise a specific supercharged air supply device (46, 50) for each type of intake means (12, 14).
Claims20
A supercharged internal-combustion engine comprising:
- at least one cylinder;
- a non-carbureted supercharged air intake;
- a carbureted supercharged air intake;
- a first intake manifold for supplying supercharged air to the non-carbureted supercharged air intake;
- and
- a second intake manifold for supplying supercharged air to the carbureted supercharged air intake.
A supercharged air supply method for a supercharged internal-combustion, engine comprising at least one cylinder with two types of supercharged air intake means for supplying supercharged air to the at least one cylinder, one type for non-carbureted supercharged air intake and another type for carbureted supercharged air intake, said intake means being supplied with supercharged air by supply means for supplying supercharged air to the intake means, characterized in that each type of intake means is supplied with supercharged air separately.
A supercharged internal-combustion, engine comprising at least one cylinder with two types of supercharged air intake means for supplying supercharged air to the at least one cylinder, one type for non-carbureted supercharged air intake and another type for carbureted supercharged air intake said intake means being supplied with supercharged air by supply means for supplying supercharged air to the intake means, characterized in that the supply means comprise a specific supercharged air supply device for each type of intake means.
