摘要： A stratified-combustion internal combustion engine according to the present invention comprises at least two intake ports situated on one side of a combustion chamber, guide passages connected individually to the intake ports, a fuel injector disposed in one of the guide passages. Each guide passage has a straight region extending over a predetermined length from its corresponding intake port. Thus, an air-fuel mixture and air, guided by the respective straight regions of the guide passages to be supplied through their corresponding intake ports to the combustion chamber, flow along the axial direction of a cylinder bore, thereby forming barrel swirl flow separated in layers from each other.

摘要： An in-cylinder injection type internal combustion engine, which includes a main fuel injection control unit that drives a fuel injector to inject fuel directly into a combustion chamber, is provided so that premixed combustion or stratified charge combustion takes place depending upon operating conditions of the engine. The engine further includes an additional fuel injection control unit that drives the fuel injector to inject additional fuel during an expansion stroke after the fuel injector is driven by the main fuel injection control unit, when it is necessary to increase the temperature of a catalyst provided in an exhaust passage for purifying exhaust gas. An exhaust manifold includes an exhaust chamber, in which the exhaust gas remains, and the additional fuel that is left unburned is re-burned in the exhaust chamber.

摘要： A vertical vortex, namely, a reverse tumble flow is formed inside a cylinder of an internal combustion engine to form an intake air flow for smooth intake and exhaust in the internal combustion engine and also to promote atomization of fuel and mixing of air and fuel in a combustion chamber. To form this reverse tumble flow, a downstream portion of an intake passage is formed extending toward a central axis of the cylinder. To promote the formation of the swirl and further to form the combustion chamber as an efficient compact combustion chamber, a recessed portion is formed in a top wall of a piston. The top wall of the piston is provided with a raised portion at a location adjacent to the recessed portion, whereby, in the vicinity of top dead center of the piston, a squish is produced in a direction flowing toward a side of a spark plug in the efficient combustion chamber. Under cooperation with the reverse tumble flow, the squish serves to have a rich air-fuel mixture centered around the spark plug upon lean burn.

摘要： When an increase in a temperature of an exhaust-gas purifying catalyst device in an in-cylinder injection type internal combustion engine is demanded, a temperature-increase control section in an electronic control unit accomplishes stratified combustion by causing each fuel injection valve to inject fuel directly into the associated combustion chamber in a compression stroke in such a way that the air-fuel ratio of the internal combustion engine is in a vicinity of a stoichiometric air-fuel ratio. This allows the temperature of the exhaust-gas purifying catalyst device to be maintained or increased without increasing fuel consumption.

摘要： An electronic control unit (40) for controlling an internal combustion engine drive executes a first operation mode for injecting a fuel in a suction stroke while making an air/fuel ratio feedback control, when a demand for improving output characteristics is made in a medium/high load drive state of the engine. In response to a demand for raising the temperature of a catalyst, moreover, the first operation mode is switched to a second operation mode in which the fuel is injected in a compression stroke while making an air/fuel ratio feedback control performing a predetermined air/fuel ratio in the vicinity of a stoichiometric air/fuel ratio as a target value. At the time of switching to each of these operation modes, moreover, the air/fuel ratio correction coefficient of the air/fuel ratio feedback is increased/decreased to promote a shift of the output turning point of an O2 sensor (22) thereby to prevent such an instability of the air/fuel ratio control as is caused by the shift of the target air/fuel ratio accompanied with the switching to each operation mode. As a result, the temperature of an exhaust purifying catalyst (3) is raised in the second operation mode for performing the compression stroke injection stably in the vicinity of the stoichiometric air/fuel ratio, so that the exhaust cleaning performance can be improved and so that the output characteristics can be improved by executing the first operation mode.

摘要： An internal combustion engine according to this invention is provided with intake ports each of which is formed to guide a flow of inducted air in a particular direction. Each intake port includes, in the vicinity of its corresponding intake opening to a combustion chamber, a bent port portion bent at a greater curvature than a port portion on a side upstream of the bent port portion. The bent port portion has a greater inner diameter than the inner diameter of the corresponding intake opening, whereby air can be inducted in a sufficient amount without deterioration to the directing function for air to be inducted into the combustion chamber.

摘要： A stratified burning internal combustion engine according to this invention is equipped with an intake port and a fuel feed device so that stratified tumble flows of different fuel concentrations can be formed in a combustion chamber. An ignition device is provided in the combustion chamber to ignite at least one of the tumble flows, said at least one tumble flow being rich in fuel. To promote the stratified tumble flows, a top wall of a piston has an inclined wall. This makes it possible to strengthen the tumble flows, whereby the stratification of an air-fuel mixture in the combustion chamber can be improved further to permit lean burn at a larger air/fuel ratio.
