Abstract:
Sound and/or vibration in a vehicle (10) is enhanced by using at least one active powertrain mount (24, 26) to selectively generate vibrations in the vehicle body (12), at least some of which are audible to a person in a cabin of the vehicle. The method can be used to enhance the sound and feel of the vehicle powertrain. The active powertrain mounts typically include at least one active engine mount (24) but may also include at least one active transmission mount (26). The active mounts (24, 26) are controlled by an ECU to attenuate unwanted powertrain vibrations in the usual way whilst simultaneously generating vibrations in the vehicle body to augment desirable engine sounds/vibrations.
Abstract:
Invention relates to method of controlling the operation of an internal combustion piston engine plant (12) in a marine vessel (10) wherein the method comprises during the operation of the internal combustion piston engine plant (12) acquiring or determining a limit value of emissions, assigning a loss factor relating to both the internal emission control system (18) and the external emission control system (20), controlling the internal emission control system such that a first reduction of emissions is obtained, controlling the external emission control system such that a second reduction of emissions is obtained, controlling the internal emission control system and the external emission control system such that the combined first and second reduction provides total emissions less than, or equal to the determined limit value of emissions, and setting the ratio of the first reduction obtained by the internal emission control system to the second reduction obtained by the external emission control system such that the total loss factor is minimized.
Abstract:
An exhaust gas purification apparatus for an internal combustion engine (1), the exhaust gas purification apparatus includes a catalyst (40), a reducing agent supply mechanism (200), a dispersion plate (60), and a control unit (80). The catalyst (40) is configured to purify exhaust gas by adding a reducing agent. The reducing agent supply mechanism (200) is configured to add the reducing agent into an exhaust passage (26). The dispersion plate (60) is provided in the exhaust passage (26) and is configured to disperse the reducing agent upstream of the catalyst (40). The control unit (80) is configured to execute addition of the reducing agent by the reducing agent supply mechanism (200), and the control unit is configured to prohibit the addition of the reducing agent when a temperature of the dispersion plate (60) is lower than a predetermined temperature.
Abstract:
The present invention proposes a method and a system for control of a low-pressure circuit in a fuel system, of a vehicle, which circuit is arranged to provide the vehicle' s engine with fuel from at least one fuel tank via a pressure change system. The system according to the present invention comprises a determination unit adapted to making a determination of a future working point for the engine. The determination unit is adapted to basing this determination on information about a section of road ahead. The system comprises also a pump operating- unit adapted to operating at least one controllable fuel pump which is part of the low- pressure circuit. The pump operating unit is adapted to basing this operation on the future working point.
Abstract:
A system and method for mitigating deposit of diesel emission fluid (DEF) decomposition products on interior surfaces of an internal combustion engine exhaust system (14). A processor in a controller (34) contains a model-based control algorithm (50A; 50B) for controlling DEF injection by a DEF injector (24) to mitigate deposit formation.

A method (200, 300) for operating an apparatus (10) is also disclosed. A method (500, 600, 700, 800, 900) associated with the operation of an apparatus (10) is also disclosed.
Abstract:
Process for transferring a liquid from a passive tank (1) for storing the liquid to an active tank (2) using a pump intended for pumping the liquid held in the passive tank (1) and transferring it to the active tank (2), according to which the pump is commanded so as to transfer liquid from the passive tank (1) to the active tank (2) when said active tank (2) has a liquid level below a set point level Lsp and when the passive tank (1) contains liquid at a temperature above the freezing point of the liquid.
Abstract:
