A chemiluminescence method for assaying compounds containing primary amino groups using 1-cyano-2-substituted benz(f)- or naphth(f)-isoindole fluorescers is disclosed. The 1-cyano-2-substituted benz(f)- or naphth(f)-isoindole (CBI or CNI) is formed by reacting a compound containing a primary amino group with naphthalene-2-3-dicarboxaldehyde or anthracene-2,3-dicarboxaldehyde in the presence of cyanide ion. The reaction product of hydrogen peroxide with an oxalate ester is then combined with the CBI or CNI to form an analyte which exhibits chemiluminescence. A detector is used to measure the chemiluminescence emission from the chemiluminescence derivatized analytes. Compounds containing primary amino groups which may be assayed according to the present invention include primary amines, amino acids, peptides and catecholamines. The method can also be adapted to the analysis of trace amounts of cyanide ion and hydrogen peroxide.

A quantity of internal EGR gases remaining in an engine is estimated in accordance with an exhaust valve closing timing, an intake valve opening timing and an engine speed. The estimated internal EGR quantity is a sum of a base quantity and an increase correction quantity determined in accordance with a valve overlap period, its middle angular position in crankshaft rotation and intake pressure. The estimated internal EGR quantity is used for estimating an engine cylinder intake air quantity and for engine control such as ignition timing control, and intake air quantity control.

In an intake-air quantity control apparatus for an internal combustion engine with a variable valve timing system, an electronic engine control module has a microprocessor programmed to perform selecting one of a first control mode in which an intake-air quantity of the engine is controlled by adjusting the throttle opening, and a second control mode in which an intake-air quantity of the engine is controlled by adjusting the intake-valve closure timing. The microprocessor is programmed to perform a number of calculating and setting steps regarding the intake-air quantity and in-take valve closure timing.

Based upon a running condition of an engine, the air-fuel ratio of the fuel mixture supplied to the engine is controlled by open loop control to a target air-fuel ratio. The engine includes a mechanism which adsorbs evaporated fuel from a fuel tank, and a purge conduit which supplies a purge gas which is a mixture of this adsorbed fuel and air to the engine in a predetermined running condition. The purge flow rate is changed according to change in the target air-fuel ratio by controlling the flow rate through the purge conduit according to the proportion between the target air-fuel ratio and a predetermined value. By doing this, deviations in the air-fuel ratio precipitated by purging are eliminated, and the accuracy of air-fuel ratio control is enhanced.

The furnace casing includes a casing body and a ceiling cover removably mounted on the casing body, and the ceiling cover can be opened in the glove box while retaining containment. A furnace member to be accommodated in the casing body comprises a combination of a plurality of divided furnace member units, and the furnace member units can be maintained by glove operations when they are delivered from the inside of the casing body into the glove box. A ceiling crane is disposed at an upper portion of the inside of the glove box, and a ceiling cover tentative space and a maintenance working space are provided in the glove box. A turntable for placing the delivered furnace member unit is preferably disposed in the maintenance working space.
摘要:
A basic fuel injection amount is calculated based on the intake air amount detected by an air flow meter, and the basic fuel injection amount is corrected based on a phase delay of an intake air amount variation between the engine and air flow meter so as to calculate a first correction injection amount. The first correction injection amount is corrected to a second correction injection amount based on an increase amount which is different according to whether or not the engine is in the idle running state. A fuel injector performs fuel injection based on this second correction injection amount. The increase amount is determined by multiplying a difference between the first correction injection amount and basic fuel injection amount, by a predetermined gain. Due to this, a shift of the air-fuel ratio to the lean side when a new load such as an air conditioner is exerted on the engine in the idle running state, is suppressed.
