Abstract: A turbojet engine with improved thrust and high-altitude capabilities. Arrangements are provided for injecting liquid oxygen or other oxidizer into the turbojet engine before the compressor section. Cooling the incoming air by the liquid oxygen reduces the air volume, which allows a fixed inlet to be matched to varying flow conditions, allowing a greater mass of air to be ingested by the compressor section and results in a lower compressor outlet temperature. Increased mass flow, combined with more fuel results in higher exhaust gas temperatures and greater thrust. The addition of oxygen to the inlet air flow allows the engine to operate at higher altitudes by preventing flameout due to rarefied air.

Abstract: An engine control unit performs homogeneous charge combustion with a rich air-fuel ratio when a NOx absorption material has absorbed a specified amount of NOx absorption so as to purge NOx and to reduce the NOx with HC and CO in an exhaust gas, thereby purifying the exhaust gas. During execution of the homogeneous charge combustion, a pressure of fuel with which a fuel injector sprays fuel is held at a pressure level for stratified charge combustion immediately before an alteration to the homogeneous charge combustion so as thereby to eliminate an occurrence of a time delay in changing the pressure of fuel upon resumption of the stratified charge combustion from the homogeneous charge combustion executed for NOx purge with an effect of preventing a fuel mixture from falling into the difficulty that the fuel mixture is hard to concentrate locally around a spark plug.

Abstract: When an engine operates in a low and medium load area and in a low and medium speed area, the combustion mode is established to a compression ignition combustion and when the engine operates in other load and speed areas, the combustion mode is established to a spark ignition combustion. Further, when the compression ignition combustion is performed, the mixture is stratified in the combustion chamber and an ultra lean combustion is realized. As a result, both NOx reduction in an ultra lean condition and HC/CO reduction in an oxidation atmosphere can be obtained. On the other hand, when the spark ignition combustion is performed, a normal feedback control of air-fuel ratio activates a three-way catalyst to reduce HC, CO and NOx simultaneously.

Abstract: The invention relates to a method for regenerating a particulate filter in the exhaust system of a diesel engine, an increase in the temperature of the exhaust gases being brought about by post-injection of fuel. The intake pressure (MAP) and/or the air mass flow rate (MAF) are reduced as a function of the ambient temperature of the engine and preferably also when the engine load is low by throttling the engine. In this way, the proportions of burned or unburned post-injected fuel can be stabilized.

Abstract: In an exhaust gas purifying apparatus of an internal combustion engine, the temperature of occlusion-type NOx catalyst is increased to emit SOx when the temperature of occlusion-type NOx catalyst is not less than a set temperature.

In this case, the temperature of the occlusion-type NOx catalyst is preferably set according to the frequency of the SOx desorption, and the temperature of the occlusion-type NOx catalyst can be increased by, for example, retarding an ignition timing.

Later, the combined exhaust gas stream can be mixed with a combined water stream.
