Abstract
Official abstract text for this publication.
Methods and systems of controlling a dual fuel engine with at least two banks of cylinders are provided. The method may include sensing at least one of temperatures of exhaust from the at least two banks and a pressure of an intake manifold of the at least two banks, and adjusting at least one of a gas flow, a charge flow, or an air flow to one of the at least two banks to balance one of exhaust temperatures of the at least two banks and intake manifold pressures of the at least two banks.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of controlling a dual fuel engine with at least two banks of cylinders, comprising: sensing at least one of temperatures of exhaust from the at least two banks and pressures of intake manifolds of the at least two banks; and adjusting at least one of a gas flow, a charge flow, and an air flow to one of the at least two banks to balance one of exhaust temperatures of the at least two banks and intake manifold pressures of the at least two banks. 2. The method of claim 1 , wherein sensing comprises sensing temperatures of exhaust from the at least two banks; and the adjusting is adjusting a charge flow to one of the at least two banks to balance exhaust temperatures of the at least two banks. 3. The method of claim 1 , wherein sensing comprises sensing a pressure of an intake manifold of each of the at least two banks; and adjusting comprises adjusting both the gas flow to one of the at least two banks and the air flow to one of the at least two banks to balance exhaust temperatures of the at least two banks and intake manifold pressures of the at least two banks. 4. The method of claim 1 , wherein sensing comprises sensing the temperatures of exhaust from the at least two banks and adjusting comprises adjusting the gas flow to one of the at least two banks to balance exhaust temperatures of the at least two banks. 5. The method of claim 2 , wherein sensing comprises virtual sensing. 6. The method of claim 2 , wherein sensing comprises physical sensing.
