Patent

CA 2575732

An engine system (100) includes a first fuel regulator (322) adapted to control an amount of a first fuel supplied to the engine, a second fuel regulator (324) adapted to control an amount of a second fuel supplied to the engine concurrently with the first fuel being supplied to the engine, and a controller (104) coupled to at least the second fuel regulator. The controller (104) is adapted to determine the amount of the second fuel supplied to the engine in a relationship to the amount of the first fuel supplied to the engine to operate in igniting the first fuel at a specified time in steady state engine operation and adapted to determine the amount of the second fuel supplied to the engine in a manner different from the relationship at steady state engine operation in transient engine operation.

Cette invention se rapporte à un système de moteur (100) incluant un premier régulateur de carburant (322) qui permet de contrôler la quantité d'un premier carburant délivré au moteur, un second régulateur de carburant (324) qui permet de contrôler la quantité d'un second carburant délivré au moteur simultanément à la délivrance du premier carburant au moteur, et un contrôleur (104) couplé au second régulateur de carburant au moins. Le contrôleur (104) permet de déterminer la quantité du second carburant délivrée au moteur par rapport à la quantité du premier carburant délivrée au moteur afin de fonctionner en allumant le premier carburant à un certain moment au cours du fonctionnement du moteur en régime permanent, et adapté afin de déterminer la quantité du second carburant délivré au moteur d'une manière différente du rapport du fonctionnement du moteur en régime permanent dans un fonctionnement de moteur transitoire.
