摘要:
There is provided a control apparatus for an internal combustion engine, which can favorably reduce a load necessary for cranking at the time of the next start, while preventing the fresh air inflow to a catalyst at the time of the stop of the internal combustion engine. A valve stop command is issued to an electrically-driven actuator (130) so that the operational states of intake and exhaust valves (58, 60) becomes a valve closed/stopped state when fuel supply is stopped in response to an establishment of a predetermined stop condition of the internal combustion engine (12). Then, to return the operational states of the intake and exhaust valves (58, 60) to a valve operating state after the completion of the stopping operation of the internal combustion engine (12), a valve return command is issued to the actuator (130), and a crankshaft (70) is rotationally driven by a predetermined angle required to return the operational states of the intake and exhaust valves (58, 60) to the valve operating state.

The present invention has an object to put into practical use an air purification system for a vehicle, which incorporates an ozone purifier formed to contain an activated carbon. The air purification system for a vehicle provided by the present invention includes an ozone purifier that is formed to contain an activated carbon therein and disposed on a surface of a vehicle component disposed at a position at which an air flow path is formed while the vehicle is running. The air purification system for a vehicle also includes a purification inhibitor remover that is disposed upstream of the ozone purifier in the above-described flow path, for removing a component inhibiting purification of ozone by the ozone purifier, from the air flowing into the ozone purifier. The ozone purifier may, for example, be disposed on a radiator and the purification inhibitor remover on a condenser or a sub-radiator.

An internal combustion engine is provided with a fuel injector 13 which injects fuel into an intake port 8 and an exhaust variable valve timing mechanism A which can change a valve timing of an exhaust valve 9. A control device executes early exhaust valve closing control which advances a closing timing of an exhaust valve when conditions for executing early exhaust valve closing control stand. Further, the control device is provided with a torque detecting means which detects an output torque which is output by an engine body 1. At the time of a deceleration operation of the internal combustion engine, even when the condition for executing early exhaust valve closing control stands, execution of the early exhaust valve closing control is prohibited when it is predicted that the output torque which is detected by the torque detecting means will become smaller than the limit torque. Due to this, due to execution of the early exhaust valve closing control, a large torque fluctuation is prevented from occurring at the time of a deceleration operation of the internal combustion engine etc.

An object of this invention is to provide an atmosphere-cleaning device for vehicles that is capable of restoring the function of an ozone purifying body carried by a vehicle component. Mud, dust, snow-melting agents as well as SOx and NOx are scattered into the atmosphere as a result of being swirled up by a preceding vehicle or due to weather and climate conditions. When such extraneous substances adhere or the like to an ozone purifying body, the purification sites thereof are clogged and the ozone purification function deteriorates. Therefore, when a predetermined removal implementation condition is established, control is executed to inject cleaning liquid from an injector 20 to enhance the fluidity of the extraneous substances and wash the extraneous substances away. The function of the ozone purifying body can thereby be restored.

摘要:
An exhaust device for an internal combustion engine is mounted on a vehicle and equipped with an exhaust passage, a reforming catalyst and a NOx purification catalyst. The exhaust passage communicates with the engine. The reforming catalyst is provided on the exhaust passage at the upstream side of the NOx purification catalyst, and it generates the reducing agent by reforming CH 4 . The NOx purification catalyst purifies NOx by means of the reducing agent generated by the reforming catalyst.
