摘要:
A method for calculating transient fuel wall wetting characteristics of an operating engine is described. The method accounts for cylinder valve deactivation of cylinders in the engine in calculating the dynamic fueling compensation. In one example, fuel vaporization effects from fuel puddles in deactivated cylinders are considered when calculating the fueling compensation for active cylinders.
摘要:
A method for controlling stopping and starting of an engine having a variable event valvetrain is described. According to the method engine valves may be used to reduce engine evaporative emissions as well as engine starting emissions.
摘要:
A system and method for controlling electromechanical valves operating in an engine is presented. According to the method, valve operation can be adjusted in a number of ways.
摘要:
A method to select cylinder and valve operational modes in an internal combustion engine with valves that may be deactivated. A simplified method to select cylinder and valve modes is presented.
摘要:
A method to deliver fuel during a start for an internal combustion engine is described. The method provides individual cylinder fuel control based on the number of fueled cylinder events. The method offers improved engine emissions while maintaining engine run-up performance.

A method to select cylinder and valve operational modes in an internal combustion engine with valves that may be deactivated. A simplified method to select cylinder and valve modes is presented.
摘要:
A method for discontinuing combustion in a cylinder of an internal combustion engine having an intake manifold and an emission control device coupled downstream of thereof, where the cylinder has at least one valve, the method comprising during a shut-down, holding the at least one valve closed for at least a cycle of the cylinder to reduce a flow of gasses from the engine to the emission control device.

The subject matter disclosed herein provides a flea vacuum. The device may include a nozzle having a first opening and a second opening. The first opening may have a tapered end and may be configured to vacuum an insect (e.g., a flea, etc). The device may also include a hose coupled to the nozzle. The device may also include an adapter coupled to the hose. The adapter may have an end configured for insertion into a vacuum. The device may also include a kill agent comprising bentonite as the active ingredient for killing and/or neutralizing pests, such as for example fleas. Related apparatus and methods are also described.
摘要:
A modular packet network device has a chassis in which multiple logic cards mate to the front side of an electrical signaling backplane. Logic power for the logic cards is supplied from a group of power converter cards that convert primary power to the logic voltages required by the logic cards. The power converter cards lie in a separate cooling path behind the backplane. Advantages achieved in at least some of the embodiments include removing primary power planes from the signaling backplane or portion of the backplane, providing redundant, upgradeable power modules whose individual failure does not cause logic card failure, and providing cool air to power converter circuits that would be subject to only heated air if located on the logic cards. Other embodiments are also described and claimed.
