  • Patent number: 10113521
    Abstract: An intake manifold is provided that controls swirl on entry to a combustion chamber. Each intake manifold includes a fin or rib portion positioned to reduce or eliminate swirl induced by the configuration of the intake manifold, particularly when used in a large engine having a left bank and a right bank of combustion chambers. By controlling swirl induced by the intake manifold, charge motion consistency is improved between engine cylinders and between the left bank and the right bank, thereby improving the consistency of combustion and power output, improving efficiency and reducing emissions (e.g., decreased particulate emissions (also described as smoke), hydrocarbon emissions, and NOx emissions), and further including an improved knock margin, improved fuel economy, wider rich and lean limits, etc.

  • Patent number: 7866852
    Abstract: According to certain embodiments, an apparatus for cooling light emitting diodes (LEDs) in projectors includes one or more first LEDs, one or more first heat sinks, one or more second LEDs, and one or more second heat sinks. The first LEDs are configured to generate light, and each first LED has a first desired junction temperature. The first heat sinks are configured to dissipate heat generated by the first LEDs. The second LEDs are configured to generate light, and each second LED has a second desired junction temperature that is higher than the first desired junction temperature. The second heat sinks are configured to dissipate heat generated by the one or more second LEDs. A cooling fan directs air flow over the first heat sinks and the second heat sinks, and an exhaust vent enables the air flow over the first heat sinks and the second heat sinks.

  • Publication number: 20090137290
    Abstract: According to one embodiment of the disclosure, a wireless telephone generally includes a housing and a heat spreading member. The housing encases a plurality of electrical components of a wireless telephone. The heat spreading member is in thermal communication with at least two distally located portion for reducing a thermal gradient over the surface of the housing.
