摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission control device that efficiently purifies particulate substance, especially extremely minute PM (particulate matter with a particulate diameter of 50 nm or less). SOLUTION: In the exhaust emission control device 10, an exhaust emission control passage 14, having a flow passage sectional area larger than the pipe passage sectional area of an exhaust pipe of an internal combustion engine, is constructed by a purifying pipe 12, and a cooling members 16 are provided. When exhaust gas from the exhaust pipe flows into the exhaust emission control passage 14, the exhaust gas contacts the cooling member 16 to be cooled. High boiling point hydrocarbon in the exhaust gas is then turned into particles and captured on the wall surface (low temperature surface) of the cooling member 16 by "thermal migration effect", suppressing generation of extremely minute PM caused by condensation of the high boiling point hydrocarbon. Condensation of gaseous volatile substance in the exhaust gas is promoted while forming particles by the cooling of the exhaust gas due to its contact with the cooling member 16, thus preventing generation of PM arising from the sulphate after it has been discharged into the air.

摘要： PROBLEM TO BE SOLVED: To provide unburned fuel from being exhausted outside from an exhaust pipe at startup of an engine capable of a compressed self-ignition operation.
SOLUTION: An intake valve and an exhaust valve can be switched between opening and closing respectively and an engine includes a sensor for detecting whether combustion is occurring or not. At a start up of the engine, the intake valve and the exhaust valve are kept in the closed state respectively and the ignition plug is ignited in each cycle after fuel is injected into a combustion chamber at least once. Then, after the sensor detects that combustion occurs, the opening/closing operation for the intake valve and the exhaust valve is started.

摘要： PROBLEM TO BE SOLVED: To make a stable, quick switch to self-ignition in an engine which uses both spark ignition and self-ignition.
SOLUTION: A combustion method of the engine is switched to self-ignition of two cycles or spark ignition of four cycles in accordance with rotation speed and required load. At the time of switching from the spark ignition to the self-ignition, processing for raising temperature of compression end is applied in order to realize stable self-ignition when temperature of exhaust is low, whereas the processing is skipped when temperature of exhaust is high. Quick switching can be realized while simultaneously starting stable self-ignition by judging whether not or processing for raising the temperature of the compression end is required on the basis of the temperature of the exhaust.

摘要： PROBLEM TO BE SOLVED: To materialize reduction of noise and vibration, and miniaturization of a rotary engine.
SOLUTION: A plurality of rotors 2a - 2d are stored in a common space enclosed by a rotor housing 1 and side housings 4a, 4b. Eccentric parts 3a - 3d rotatably supporting the rotors 2a - 2d interlock with an output shaft 3 while keeping eccentricity to the output shaft 3 and keeping a condition where inertia force in eccentric rotation of the rotor is balanced by the whole rotors 2a - 2d stored in the common housing. Consequently, dynamic unbalance caused by eccentric motion of the rotors 2a - 2d is suppressed and rotor intervals are shortened by just that much of omitting the side housings between the rotors 2a - 2d.

摘要： PROBLEM TO BE SOLVED: To suitably switch operating conditions of an internal combustion engine from compressed self-ignition operation to spark ignition operation.
SOLUTION: When the operating conditions are switched from the compressed self-ignition operation to the spark ignition operation according to increase of target torque, a quantity of fuel injection is once gradually increased in a condition of stratified spark ignition operation and air-fuel ratio of a fuel-air mixture is gradually decreased. Then, when the air-fuel ratio is decreased to a predetermined value, the operation is switched into the spark ignition operation while the air-fuel ratio is decreased to a theoretical air-fuel ratio at a stretch. Thus, the operating conditions can be stably switched by passing through the stratified spark ignition operation, and output torque is not rapidly increased and the operating conditions can be switched without sense of incongruity by switching the operating conditions while gradually increasing the fuel. Further, discharge of atmospheric pollutants such as nitrogen oxides is not increased by switching the air-fuel ratio to the theoretical air-fuel ratio at a stretch when the air-fuel ratio reaches predetermined air-fuel ratio.

摘要： PROBLEM TO BE SOLVED: To prevent undesired premature ignition and knocking due to high temperature of gas in a cylinder immediately after switching to two cycle operation from four cycle operation.
SOLUTION: When switching to premix compression self ignition two cycle operation from premix spark ignition four cycle operation is carried out, an exhaust valve 134 is opened for a long time or twice in a transition period to suck exhaust gas discharged to an exhaust port 16 once in a cylinder 142 again. Since temperature of exhaust gas discharged once and sucked in again via the exhaust valve 134 drops due to heat exchange, gas temperature in the cylinder during premix compression self ignition two cycle operation drops and undesired premature ignition and knocking do not occur.

摘要： PROBLEM TO BE SOLVED: To smoothly switch a four-cycle operation and a two-cycle operation in a variable cycle engine. SOLUTION: An engine has a first operational mode to perform the four-cycle operation and the two-cycle operation while igniting fuel in a fuel chamber by an ignition unit. The first operational mode comprises a first normal mode of relatively high real compression ratio and a first transition mode of relatively low real compression ratio which is performed before starting the first normal mode after completing the second operational mode. The four-cycle operation is smoothly switched from the two-cycle operation without any knocking by performing the operation in the first transition mode of relatively low real compression ratio.
