摘要： In a fuel injection nozzle including multiple nozzle hole groups each having multiple solitary nozzle holes, a group distance C between two of the nozzle hole groups is 0.8 or more times larger than an in-group hole distance α in a nozzle hole group. The group distance C is the minimum interval of inter-group intervals that are formed between (i) peripheral boundaries of solitary nozzle holes belonging to a first nozzle hole group and (ii) peripheral boundaries of solitary nozzle holes belonging to a second nozzle hole group adjacent to the first nozzle hole group. The in-group hole distance α is the minimum of intervals between peripheral boundaries belonging to each nozzle hole group.

摘要： An exhaust gas purifying apparatus for an internal combustion engine includes a collector, which collects exhaust particles in exhaust gas. The apparatus computes a pressure-difference-based measured value of a collected amount of the particles based on a pressure difference, and computes a pressure-difference-based estimated value by correcting the measured value. The apparatus computes an operational-state-based estimated value of the collected amount. The apparatus regenerates the collector by burning the exhaust particles when one of the pressure-difference-based estimated value and the operational-state-based estimated value reaches a predetermined value. The apparatus computes a current pressure-difference-based estimated value by correcting a current pressure-difference-based measured value based on information related to an immediately preceding operational-state-based computing period such that the current pressure-difference-based estimated value ranges from the current measured value to a previous pressure-difference-based estimated value.

摘要： A flow rate of gas supplied to a diesel particulate filter is increased when it is determined that rapid combustion of collected particulates, which are collected by the particulate filter, is likely to occur based on an operating state of an internal combustion engine. Alternatively, the flow rate of gas supplied to the filter is increased when it is determined that rapid combustion of the collected particulates is initiated based on a state of the particulate filter.

摘要： The engine control system has an ECU that supplies relatively large amount of EGR gas and delays an injection timing in order to decrease temperature in a combustion chamber. When an engine is operated under a warming up operation or a low engine load, the ECU deactivates an EGR cooler to increase intake air temperature in order to stabilize engine operation. When the engine is operated under a high engine load, the ECU activates the EGR cooler, delays a closing timing of an intake valve, and increases a boost pressure of a forced induction system. As a result, both of a compression end temperature and a maximum combustion temperature are decreased so that emissions of NOx and particulates are reduced.

摘要： A control apparatus for rapidly warming up a catalyst disposed within an exhaust pipe connected to an internal combustion engine. The control apparatus first determines a fuel injection amount and an ignition timing of the engine on the basis of an engine operating condition such as an intake air pressure of the engine and a rotational speed of the engine. The control apparatus is also responsive to temperature information of the catalyst for adjusting the fuel injection amount and the ignition timing in accordance with the catalyst temperature information. When the catalyst temperature does not reach the effective emission-purifying temperature, the control apparatus alternately adjusts the fuel injection amount to a rich amount and a lean amount and further intermittently retards the ignition timing. This injection and ignition control operation allows acceleration of the warming-up of the catalyst to suppress the deterioration of the emissions from the engine.

摘要： A control system for an engine has a temperature sensitive element as part of a device for measuring the air flow in an air intake manifold to the engine. Further, a first pulse signal is generated, corresponding to the rotation of the engine, for controlling the setting of a flip-flop. A transistor is conducted in the set state of the flip-flop to supply a heating electric current to the element. The element supplied with the current is raised to the temperature that corresponds to the air flow in the manifold. When the temperature of the element is raised until the specified temperature difference to the air temperature (measured by a sub temperature sensitive element) is set, the temperature difference is detected by a comparator, and the flip-flop is reset by the detection signal. A pulse-shaped signal corresponding to the set state of the flip-flop is produced as a measurement output signal, supplied as one detection signal of the operating state of the engine to an engine control unit, and the current to the element is controlled to be supplied by the pulse-shaped signal.
