    摘要: This invention provides an exhaust gas purifier for a diesel engine provided with a continuous regeneration-type DPF using a catalyst. A by-pass passage is provided in an exhaust passage (7) in a diesel engine provided with a continuous regeneration-type DPF (12), and a small-capacity second continuous regeneration-type DPF (13) is installed. In a low-exhaust gas temperature region, PM is collected by the second continuous regeneration-type DPF (13). In this case, premixing combustion in which fuel injection timing for injecting a fuel into a cylinder is hastened is carried out to reduce the amount of PM produced. Accordingly, satisfactory collection can be carried out even when the capacity of the second continuous regeneration-type DPF (13) is small. Further, since the production of NOx is suppressed, a cooled exhaust gas is recirculated into a cylinder. Further, a urea-added SCR catalyst is installed in the exhaust passage (7) for reductive decomposition of NOx contained in the exhaust gas to further reduce NOx.

    摘要: A lift-control device for a valve (2), valve-lift means. A first valve-lift means (5) with (6) a profile of a cam (11) or eccentric acting on a rocker (6) in order to cause it to oscillate about a first axis (B) so as to move the valve (2) according to a first valve-lift law; a second valve-lift means (10) with an auxiliary rocker, (10) which co-operates in contact with the first valve-lift means (5) for receiving a motion of oscillation about a second axis (C) and a profiled portion of one between said rocker (6) and said auxiliary rocker(20), having a profile that defines the second valve-lift law.

    摘要: A method of operating a four stroke internal combustion engine comprising the steps of using inlet valve means (15) to regulate admission of a mixture of fuel and air into a combustion chamber (12), using a compressor (151) to compress the fuel and air mixture prior to admission of the mixture into the combustion chamber (12), using exhaust valve means (16) to regulate flow of combusted gases from the combustion chamber (12), closing the exhaust valve means (16) prior to the end of the exhaust stroke to trap combusted gases in the combustion chamber (12), opening the inlet valve means (15) during the intake stroke to admit a charge of fuel and air mixture into the combustion chamber (12) to be mixed with the previously trapped combusted gases, whereby in the combustion chamber (12) conditions are generated which enable the mixture of fuel, air and combusted gases to combust by auto-ignition, with the combusted gases expanding during the power stroke.
    By opening the inlet valve means (15) to admit a preconditioning charge of fuel and air into the combustion chamber (12) to be mixed with the trapped combusted gases after closing of the exhaust valve means (16) during the exhaust stroke and prior to the opening of the inlet valve means (15) in the induction stroke to admit the charge of fuel and air which is combusted to expand in the power stroke.

    摘要: The present invention relates to a method of operating a four-stroke internal combustion engine comprising the steps of: closing an exhaust valve (16) prior to the end of the exhaust stroke to trap combusted gases in a combustion chamber (12); opening an inlet valve (15) during the intake stroke to admit charge into the combustion chamber (12) to be mixed with previously trapped combustion gases; and using an injector (60) to inject fuel into the mixture of the trapped combusted gases and the charge air. In the combustion chamber conditions are generated which enable the mixture of fuel, air and combusted gases to combust by auto-ignition. The injector (60) is additionally used to inject fuel into the trapped combusted gases after closing of the exhaust valve (16) during the exhaust stroke and prior to opening of the inlet valve (15) in the induction stroke.
