PORT FUEL INJECTION [7 records]

Record 1 2022-09-12

English

Subject field(s)
  • Fueling Systems (Motor Vehicles)
  • Engines (Motor Vehicles)
  • Diesel Motors
  • Gasoline Motors
CONT

With port fuel injection, gasoline is sprayed into the intake manifold, where it mixes with air, and then is sucked down into the cylinders.

Domaine(s)
  • Alimentation (Véhicules automobiles)
  • Moteur (Véhicules automobiles)
  • Moteurs diesel
  • Moteurs à essence
CONT

Injection dans l'orifice d'admission : le carburant est pulvérisé dans les orifices d'admission, avant la chambre de combustion.

English

Subject field(s)
  • Fueling Systems (Motor Vehicles)
CONT

[This engine] is also the first North American application of a bottom-feed fuel rail in a port injection system, permitting the injectors to be packaged within the rail and allowing the fuel to cool the entire injector for better hot starts.

Record 3 2011-06-30

English

Subject field(s)
  • Ignition Systems (Motor Vehicles)
  • Engines (Motor Vehicles)
CONT

By increasing the iso-octane percentage in the fuel from 0-50%, it was shown that the HCCI [homogeneous charge compression ignition] engine lost combustion efficiency and combustion phasing was slowed.

CONT

It was found that low level of fuel stratification obtained with asymmetric port fuel injection does not significantly affect the combustion phasing...

Domaine(s)
  • Allumage (Véhicules automobiles)
  • Moteur (Véhicules automobiles)
CONT

[...] il est apparu que le niveau de stratification de la charge obtenu par l’utilisation d’injection indirecte dissymétrique ne permet pas de modifier le déroulement de la combustion.

Record 4 2004-12-10

English

Subject field(s)
  • Engines (Motor Vehicles)
OBS

Direct injection(DI) refers to fuel injected directly into the combustion chamber above the piston. Direct injection has long been used on large diesel engines. Smaller diesels are increasingly adopting direct injection(vs. indirect injection into a pre-chamber). Direct injection also can be used in spark ignition(generally gasoline) engines instead of port fuel injection-for cleaner emissions, increased full throttle power and potentially for lean-burn operation.

Key term(s)
  • direct-injection engine

French

Domaine(s)
  • Moteur (Véhicules automobiles)
DEF

Moteur à combustion interne dans lequel le carburant est injecté sous pression directement dans la chambre de combustion.

OBS

À noter que les moteurs à injection directe peuvent utiliser du diesel ou de l'essence.

Record 5 2004-05-03

English

Subject field(s)
  • Fueling Systems (Motor Vehicles)
CONT

Sequential fuel injection is port injection timed to the opening of each injector's associated intake valve so that fuel is delivered to each cylinder in its proper firing sequence, not to part or all of the cylinders at once.

CONT

The engine employs sequential multiport electronic fuel injection, twin nozzle side-feed injectors, a four-stage variable induction system, and a cone-type airflow sensor.

French

Domaine(s)
  • Alimentation (Véhicules automobiles)
CONT

À bien des égards, l'injection directe représente une étape de plus dans l'évolution des systèmes d'alimentation des moteurs à essence. Lors de chaque étape de cette évolution (où l'on est passé du carburateur mécanique à l'injection monopoint et multipoint, puis à l'injection multipoint séquentielle), on a tiré avantage d'améliorations apportées aux injecteurs et aux systèmes de commande électroniques, pour réaliser des progrès graduels dans la maîtrise des moteurs à combustion interne.
