摘要： A control device is applied to a multi-cylinder 4-cycle charge compression ignition-type internal combustion engine. The control device operates to open an exhaust valve in an exhaust stroke of each cylinder, operates to close an intake valve before an intake bottom dead center, and then, operates to open the exhaust valve again before the intake bottom dead center. An exhaust flow rate regulating valve is disposed in a collecting portion of an exhaust path and its opening is controlled. Hereby, a period in which the exhaust valve is open in an intake stroke of one cylinder and a period in which the exhaust valve is open in an exhaust stroke of another cylinder partially overlap each other. Combustion gas pushed out of a combustion chamber of the other cylinder in the overlapping period is pushed into a combustion chamber of the one cylinder via the exhaust path.

摘要： An evaporative fuel emission control system includes a canister that adsorbs fuel vapor generated in a fuel tank, a canister outgoing gas producing unit that causes a canister outgoing gas to flow out of the canister, a vapor condensing unit that condenses the canister outgoing gas to provide a processed gas containing a higher concentration of fuel vapor than that of the canister outgoing gas, and a processed gas passage through which the processed gas is fed to the fuel tank. A controller of this system is operable to restrict flow of the processed gas into the fuel tank when the fuel vapor concentration in the processed gas is lower than or is expected to be lower than a predetermined level.

摘要： A canister adsorbs evaporative fuel generated in a fuel tank. A purge gas circulation pump causes canister outlet gas to flow out from the canister. A high-concentration separation unit separates canister outlet gas into high-concentration treating gas and medium-concentration gas. A medium-concentration separation unit separates medium-concentration gas flowing out from the high-concentration unit into medium-concentration circulating gas and low-concentration canister inlet gas. Treating gas is introduced into the fuel tank. Circulating gas is caused to circulate upstream of the purge gas circulation pump. Canister inlet gas is caused to circulate upstream of the canister.
