Abstract
Systems and methods for intake manifold overpressure compensation for internal combustion engines with gaseous induction fuel systems are disclosed. The systems and methods include a connecting element that extends between and fluidly connects the downstream ends of first and second intake manifold banks of the internal combustion engine.
Claims20
An internal combustion engine system, comprising:
- an engine including a first plurality of cylinders along a first side of the engine and a second plurality of cylinders along a second side of the engine;
- an intake system including a main intake line for providing a charge flow to the engine, the intake system further including a first intake manifold portion connected to the first plurality of cylinders along the first side of the engine and a second intake manifold portion connected to the second plurality of cylinders along the second side of the engine, the first and second intake manifold portions further being connected to the main intake line upstream of the first and second plurality of cylinders to receive the charge flow therefrom and provide the charge flow to respective ones of the first and second plurality of cylinders;
- and
- a connecting element extending between and fluidly connecting the first and second intake manifold portions downstream of the first and second plurality of cylinders.
1 more element
An internal combustion engine system, comprising:
- an engine including a first plurality of cylinders along a first side of the engine and a second plurality of cylinders along a second side of the engine;
- an intake system including a first intake manifold portion connected to the first plurality of cylinders along the first side of the engine and a second intake manifold portion connected to the second plurality of cylinders along the second side of the engine, the first and second intake manifold portions each receiving a charge flow from an upstream end thereof, wherein the upstream end is located upstream of the first and second plurality of cylinders;
- and
- a connecting element extending between the first and second intake manifold portions downstream of the first and second plurality of cylinders, wherein the connecting element provides a flow passage to allow a burning gas of the charge flow in one of the first and second intake manifold portions to expand into the other of the first and second intake manifold portions in response to an overpressure event.
1 more element
A method for operating an internal combustion engine, comprising:
- providing a charge flow to first and second intake manifold portions from an upstream end of the first and second intake manifold portions, wherein the first intake manifold portion is fluidly connected to a first plurality of cylinders along a first side of the internal combustion and the second intake manifold portion is fluidly connected to a second plurality of cylinders along a second side of the internal combustion engine;
- and passing the charge flow through a connecting element that extends from a downstream end of one of the first and second intake manifold portions to a downstream end of the other of the first and second intake manifold portion in response to a burning gas in the one of the first and second intake manifold portions.
