    摘要: A method for controlling start of a compression ignition engine having a plurality of cylinders is provided without a cam sensor is provided. Each cylinder includes a respective piston reciprocally movable between respective top and bottom positions along a cylinder longitudinal axis. The method comprises providing a respective fuel delivery assembly for each cylinder. In one embodiment the method further comprises retrieving from memory a set of fuel delivery assembly firing rules and then processing the firing rules so that a firing signal is delivered to each fuel delivery assembly on every crank revolution during a cranking mode of operation. The fuel delivery assembly is arranged to be responsive to any firing signal received during an injection window leading to the top position along the longitudinal axis so as to supply fuel to each cylinder during that injection window. The fuel delivery assembly is further arranged to be insensitive to any firing signal received during an exhaust stroke leading to the top position along said longitudinal axis so that no fuel is delivered to each cylinder during that exhaust stroke.

    摘要: The present invention addresses the need to improve the yields of viral vectors when grown in cell culture systems. In particular, it has been demonstrated that for adenovirus, the use of low-medium perfusion rates in an attached cell culture system provides for improved yields. In other embodiments, the inventors have shown that there is improved Ad-p53 production with cells grown in serum-free conditions, and in particular in serum-free suspension culture. Also important to the increase of yields is the use of detergent lysis. Combination of these aspects of the invention permits purification of virus by a single chromatography step that results in purified virus of the same quality as preparations from double CsCl banding using an ultracentrifuge.

    摘要: A common rail fuel injection apparatus (1) for a multi-bank, diesel locomotive engine (10). A common rail (20,22) is disposed proximate each bank (20,22) of cylinders (12) of the engine to provide high pressure fuel (30) to a fuel flow control apparatus (14) associated with each respective cylinder. A plurality of high-pressure fuel pumps (34) provides high-pressure fuel to at least one of the common rails. A fluid cross connection (38) is provided to convey high pressure fuel between the two common rails, thereby providing for the continued delivery of fuel to all cylinders in the event of a failure of one of the high pressure pumps. The high-pressure pumps are motivated by fuel lobes (64) located on camshaft sections (50a, 50b, 50c) adjoined at a gear driven end 58 of the camshaft (50). Camshaft sections (50d, 50e, 50f) adjoined at an idler end (60) of the camshaft carry lower torque loads than those sections having fuel lobes and may be formed from a lower strength material or may have a smaller shaft diameter.

    摘要: A circuit is provided for over-driving a super-luminescent light emitting diode having a maximum forward continuous current rating. A power supply provides a pulse width modulated signal to an analog memory connected to the power supply and a pulse generator. The pulse generator includes a window comparator engaged with the analog memory, and is responsive to a portion of the pulse width modulated signal. A power driver that is controlled by the output of the pulse generator, is operably connected with the super-luminescent light emitting diode and with the power supply so as to energize the super-luminescent light emitting diode with a current that is above the maximum forward continuous current rating by between two and ten times that rated current. A signal is also provided along with a method of over-driving a super-luminescent light emitting diode.
