    摘要: An internal combustion engine control apparatus includes means that detects an inlet temperature that is a temperature in a vicinity of an inlet of a purification catalyst disposed in an exhaust path and means that detects a turbine temperature that is a temperature in a vicinity of an exhaust turbine of a turbo-supercharger disposed in the exhaust path, and also includes means that controls a valve overlap that is a state in which an intake valve and an exhaust valve of the internal combustion engine are open simultaneously. When the inlet temperature is lower than an inlet high temperature reference value, and the turbine temperature is higher than a turbine high temperature reference value that is higher than the inlet high temperature reference value, the valve overlap amount is increased so as to be greater than a turbine high temperature time reference amount.

    摘要: A misfire detection method is provided, which method makes it possible to accurately detect the occurrence/absence of misfire by eliminating a detection error in misfire detection. This error is caused by a vibrational increase or decrease of the rotational changing rate of a crankshaft after a misfire state occurs. A processor, which receives pulse outputs from a crank angle sensor, calculates in sequence angular accelerations D.omega..sub.n-2, D.omega..sub.n-1, D.omega..sub.n, and D.omega..sub.n+1 in crank angle areas which correspond to a preceding cylinder, two cylinders checked for misfire, and a succeeding cylinder, respectively. If the values D.omega..sub.n-1 and D.omega..sub.n n significantly decrease in comparison with the values D.omega..sub.n-2 and D.omega..sub.n-1, respectively, then it is tentatively determined that misfire has occurred in both cylinders checked. Then If the value D.omega..sub.n+1 significantly increases compared to the value D.omega..sub.n, then the restoration to the normal combustion state is confirmed, and the occurrence of misfire in the two cylinders checked is definitely determined.

    摘要: A system for a vehicle includes a filtering module, an indicated mean effective pressure (IMEP) determination module, and a stuck mechanism indicator module. The filtering module generates engine speeds based on positions of teeth of a toothed wheel that rotates with a crankshaft and based on a crankshaft position signal generated by a crankshaft position sensor. The IMEP determination module determines an IMEP for a combustion cycle of a cylinder of an engine based on squares of first and second ones of the engine speeds during the combustion cycle. The stuck mechanism indicator module selectively diagnoses a fault in a variable valve lift (VVL) mechanism of the cylinder based on the IMEP.

    摘要: The process and apparatus described seeks to prevent NO.sub.x emissions after an emergency shutdown in a process for manufacturing nitric acid by catalytic combustion of ammonia, compression of the nitrous combustion gases and subsequent absorption. Immediately on shutdown the intake nitrous gas supply to the compressor is interrupted, the residual intake side nitrous gases are conveyed to the delivery side, the delivery side gas volume is shut off, the gas on the delivery side is expanded to the intake side and then exhausted into a vacuum system. Subsequently the acid charged with NO.sub.x in the absorption stages is drawn off, degassed acid is circulated through the absorption stages until equilibrium is established, the pressure of the shutoff section is released and cooled acid is admitted to the absorption stages.

In one preferred embodiment of the invention said control means comprises a valve means for controlling the supply of pressure fluid to the cylinder, for the retraction of the piston, and for controlling the exhausting of said pressure fluid from the cylinder, for the advance of the piston, a chamber or chambers connected to the cylinder so that a fluid therein will be subjected to pressure changes by movement of the piston, and means responsive to pressures in said chamber or chambers and operative cyclicly to switch said valve means between a pressure fluid supply position and a pressure fluid exhaust position. Conveniently said chamber or chambers is or are connected to the cylinder so that the fluid in said chamber or chambers will be compressed by retraction of the piston. The pressure fluid, for the operation of the tool, may be a liquid and the fluid in the chamber or chambers, which is compressible, may be a gas. Alternatively the pressure fluid, for the operation of the tool, may be a compressible liquid and the fluid in the chamber or chambers a similar compressible liquid.
