摘要: A vehicle having a combustion engine supercharged by means of a turbocharger (6) with variable turbine geometry and having electronic control members (3) controlling the supply of fuel and air to the combustion chamber of the engine. The control members are designed, during forward travel of the vehicle, on the basis of input information on at least road gradient and gas pedal position, to estimate future road resistance and the time period up to a future transient in the operating condition of the engine. The control members are designed to control changes in the turbine geometry during said time period so as to optimize the response of the engine when the transient arises.

摘要: Method and arrangement for achieving lower emissions during operation of a vehicle that includes comprising a combustion engine ( 10 ) that emits exhaust gases into an exhaust system ( 140 ) having a catalyzes ( 320 ). An injection device ( 310 ) is arranged to inject a substance into the exhaust system and a transmission ( 90 ) is provided that is driven by the engine. The method includes selecting a gear in the vehicle's transmission in response to at least information about whether catalytic conversion is required and information about the temperature (T) in the exhaust system so that the selected gear regulates the temperature in the exhaust system.

摘要: The invention relates to a device for catalytic treatment of a gas flow comprising at least one body (1) which includes a catalytic material. The device has a number of first openings (5) for either entry of gas into or exit of gas from said catalyzer body (1), and a second opening (6) for either exit of the gas entering through the first openings or entry of gas into said catalyzer body (1) for subsequent exit through the first openings.

摘要: The invention relates to an apparatus for controlling valve movements in an internal combustion engine which has at least one inlet valve (12) and at least one exhaust valve for controlling the connection between the combustion chamber in the cylinder and an inlet system and an exhaust system respectively. A rotatable camshaft which has a cam curve comprising a rising ramp (10a) and a falling ramp (10b) is designed to interact with a valve mechanism (14) for actuation of the inlet or exhaust valve (12) under the action of a valve spring (13). The valve mechanism (14) comprises control members (21-25, 26) which allow the return movement of the valve mechanism to be controlled during the closing phase of the inlet valve (12) or the exhaust valve, independently of the falling ramp (10b) of the cam curve. The control members (21-25, 26) are arranged so that the closing of the valve can be delayed for an adjustable period of time by means of a hydraulically adjustable force counteracting the closing force of the valve spring.

摘要: A vehicle with a combustion engine (1) that has valves (7,8) with variable valve timing and/or valve lift height. The valves are provided with operating devices (9,10) that are controlled by electronic controlling devices (3), which are arranged, while the vehicle is being driven, with the aid of entered information about at least the gradient of the road and the throttle position, to calculate future resistance to forward motion and the period of time to a future transient in the engine's operating condition, for example in association with a future change of engine operating mode and/or a future gear change in a gearbox (2) connected to the engine. The controlling devices are arranged to control valve timing and/or the valve lift height during said period of time for optimization of the engine's performance, once the transient has arisen.
