Beverage cartridge and method for beverage formation using filter aid

A method and apparatus for forming a beverage involves the use of a filter aid, e.g., that is provided in a beverage cartridge with a beverage medium in a dry state. In one embodiment, a cartridge including a dried fruit material may also include a filter aid, such as perlite, diatomaceous earth or cellulose, that is mixed together with the fruit material. The filter aid may assist in flow through the beverage medium or through a filter, e.g., by helping prevent the clogging of pores of a filter used to remove particulate from a beverage formed by interaction of the beverage medium with water introduced into the cartridge. Thus, the filter aid may permit the use of some beverage media that would otherwise clog a filter and / or prevent proper dissolution of materials in the beverage media without the filter aid.

Exhaust emission control apparatus of internal combustion engine and method thereof

An exhaust emission control apparatus includes a NOX catalyst provided within an exhaust passage of an internal combustion engine where fuel combustion is continuously performed at a lean air / fuel ratio, and a reducing agent supply valve within the exhaust passage upstream of the NOX catalyst. If the NOX stored in the NOX catalyst is required to be decreased, a selector valve position is selected between a forward and a reverse flow positions so as to decrease a flow rate of the exhaust gas flowing through the NOX catalyst. Then a reducing agent is supplied upon elapse of a predetermined time period from the timing when the signal instructing to select the position of the selector valve. An oxygen sensor detects an oxygen concentration of the exhaust gas discharged from the NOX catalyst upon supply of the reducing agent. The elapsing time is corrected such that a peak value of the detected oxygen concentration accords with the target value.

Crankcase ventilation pressure management for turbocharged engine

A crankcase ventilation system for a turbocharged engine has full bi-directional flow for an idle state and a boosted state. A PCV valve provides air flow from the crankcase to the intake manifold in the idle state. A restriction in a first vent line limits fresh air into the crankcase in the idle state. A PCV bypass permits a one-way flow into the crankcase via a second vent line bypassing the PCV valve in the boosted state. A pressure relief valve in communication with the first vent line is configured to bypass the restriction in the boosted state when a pressure in the crankcase exceeds a threshold pressure. In a preferred embodiment, the PCV bypass is configured to bypass both the PCV valve and a pull separator (i.e., oil separator at the second vent line) in the boosted state.
