Abstract: During sulfur release control in an internal combustion engine, a rich period and a lean period are alternately repeated. The air-fuel ratio of exhaust gas is controlled toward a target air-fuel ratio (14.3) by adding fuel from a fuel adding valve in the rich period. An ECU determines whether the actual air-fuel ratio of exhaust gas detected by an air-fuel ratio sensor has reached a stoichiometric air-fuel ratio each time the rich period ends at which addition of fuel from the fuel adding valve is stopped. A counter counts the number of times the ECU has determined that the actual air-fuel ratio of exhaust gas has not reached the stoichiometric air-fuel ratio. When the value of the counter becomes greater than or equal to a permissible value, the ECU determines that there is an abnormality in the sulfur release control.

Abstract: In a diesel engine provided with a diesel particulate filter 81 and an exhaust throttle valve 9, noise is decreased that is produced when the exhaust throttle valve is returned back to the fully opened state after a diesel particulate filter 81 has been regenerated by oxidizing and removing the particulate matter deposited thereon. The exhaust system of the diesel engine is equipped with the diesel particulate filter 81 and a catalyst 82 on the upstream thereof, and is further equipped with the exhaust throttle valve 9 on the downstream. The diesel particulate filter 81 is regenerated by operating the diesel engine in a state where the exhaust throttle valve 9 is opened to a small degree. When the regeneration has finished, the diesel engine is run at a decreased rotational speed and, thereafter, the exhaust throttle valve 9 is returned back to the fully opened state.

Abstract: An electronic control unit of an internal combustion engine calculates a basic post-injection quantity of temperature increasing means if a deposition quantity of particulate matters deposited on a diesel particulate filter (DPF) exceeds a predetermined value. Then, a final post-injection quantity is calculated by correcting the basic post-injection quantity based on a temperature correction value, which is calculated by multiplying a deviation between DPF upstream exhaust gas temperature and target temperature and past temperature correction values by feedback gains. The feedback gains are switched in accordance with a delay in an exhaust gas temperature change in a present operating state, based on an intake air quantity sensed by an air flow meter. Thus, response can be improved, while maintaining stability.

Abstract: High-efficiency combustion engines, including Otto cycle engines, use a steam-diluted fuel charge at elevated pressure. Air is compressed, and water is evaporated into the compressed air via the partial pressure effect using waste heat from the engine. The resultant pressurized air-steam mixture then burned in the engine with fuel, preferably containing hydrogen to maintain flame front propagation. The high-pressure, steam-laden engine exhaust is used to drive an expander to provide additional mechanical power. The exhaust can also be used to reform fuel to provide hydrogen for the engine combustion. The engine advantageously uses the partial pressure effect to convert low-grade waste heat from engine into useful mechanical power. The engine is capable of high efficiencies (e.g. >50%), with minimal emissions.
