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.
Claims22
A method of operating a forced induction gaseous-fueled engine, the engine comprising a bypass line, a charge air cooler, a throttle valve, an intake manifold, and a plurality of cylinders, the method comprising:
- delivering fuel during engine start through a bypass line to the intake manifold for delivery to the plurality of cylinders, completely bypassing the charge air cooler and the throttle valve during a bypass period.
A fuel bypass arrangement for a forced induction gaseous-fueled engine, the fuel bypass arrangement comprising:
- a bypass line;
- a charge air cooler;
- a throttle valve;
- an intake manifold;
- and
- a plurality of cylinders,
- wherein fuel is delivered during engine start through a bypass line to the intake manifold for delivery to the plurality of cylinders, completely bypassing the charge air cooler and the throttle valve.
A power backup system comprising a forced induction gaseous-fueled engine, the engine comprising:
- a bypass line, a charge air cooler, a throttle valve, an intake manifold, and a plurality of cylinders,
- wherein fuel is delivered from a fuel source during engine start through a bypass line to the engine intake manifold for delivery to the plurality of cylinders, completely bypassing the charge air cooler and the throttle valve.
