Abstract
A method of operating a forced induction gaseous-fueled engine includes mixing gaseous-fuel and engine intake air to form a mixture at a fuel mixer. The method includes delivering the mixture to an intake manifold by at least partially bypassing a charge air cooler.
Claims25
A method of operating a forced induction gaseous-fueled engine comprising:
- mixing gaseous-fuel and engine intake air to form a mixture at a fuel mixer;
- delivering the mixture to an intake manifold via a bypass mixture line by at least partially bypassing a charge air cooler;
- and
- providing a throttle valve being positioned between, and in fluid communication with, the charge air cooler and an intake manifold,
- wherein the bypass mixture line is upstream from an inlet of the charge air cooler and the intake manifold and downstream from the throttle valve.
2 more elements
A fuel bypass arrangement for a forced induction gaseous-fueled engine, the fuel bypass arrangement comprising:
- a compressed fuel/air mixture line configured to transport a compressed fuel/air mixture;
- a charge air cooler positioned between, and in fluid communication with, the compressed fuel/air mixture line and a throttle valve, the charge air cooler being configured to reduce a temperature of the fuel/air mixture as the fuel/air mixture travels from an inlet to an outlet of the charge air cooler;
- the throttle valve being positioned between, and in fluid communication with, the charge air cooler and an intake manifold, wherein the throttle valve is configured to control the amount of fuel/air mixture that is delivered to the intake manifold from the charge air cooler;
- a bypass line in fluid communication with the compressed fuel/air mixture line, upstream from the inlet of the charge air cooler and the intake manifold and downstream from the throttle valve;
- and
- a bypass valve in fluid communication with the bypass line, the bypass valve being configured to selectively control the flow of the fuel/air mixture through the bypass line.

A power backup system comprising:
- a generator including:
- a compression device;
- a charge air cooler positioned downstream from the compression device;
- an intake manifold positioned downstream from the charge air cooler;
- a throttle valve positioned between, and in fluid communication with, the charge air cooler and an intake manifold;
- a bypass line connected upstream from the charge air cooler and downstream from the throttle valve, wherein a fuel/air mixture is delivered to the intake manifold via the bypass line by at least partially bypassing the charge air cooler;
- a combustion system for generating mechanical power;
- and
- an electricity generating system for generating electrical power from the combustion system.
