    Abstract: A heating and cooling system for a vehicle having an internal combustion engine is provided. The system comprises at least one exhaust pipe conveying exhaust gases away from the engine, and a reactor vessel located in the exhaust pipe and containing an absorbent salt and a refrigerant fluid. A condenser is in fluid communication with the reactor vessel, and receives refrigerant vapour from the reactor when exhaust gases heat the reactor vessel in the exhaust pipe. An evaporator is locatable in a cab of the vehicle and is in fluid communication with the condenser and the reactor vessel. The evaporator receives condensed refrigerant from the condenser so as to cool the air surrounding the evaporator, and returning refrigerant vapour to the reactor vessel. A method of cooling a driver environment of a vehicle having an internal combustion engine is also provided, as is a vehicle incorporating the heating and cooling system.

    Abstract: A control process for controlling an engine speed governor of an engine is provided. The process comprises the steps of calculating the current engine power being developed by the engine, and determining an appropriate engine speed for the current engine power based upon a first engine map. The process then instructs the speed governor to adjust the engine speed in accordance with the first map if required. The process monitors for desired engine power requests, and calculates a power ratio of desired engine power versus current engine power upon receiving a desired engine power request. The process then establishes an engine speed adjustment value based upon a second engine map of power ratio versus speed adjustment value, and instructs the speed governor to adjust the engine speed in accordance with the speed adjustment value. A speed governor system incorporating the control process, and a work machine or vehicle incorporating such a system are also provided.

    Abstract: A combustion engine exhaust gas after-treatment device includes a first selective catalytic reduction (SCR) device, a second SCR device downstream of the first and a diesel particulate filter (DPF) between the first and second SCR devices. A method of dosing the after-treatment device includes: allowing dosing of the first SCR device with reductant only when its temperature is within its the operating temperature range; and allowing dosing of the second SCR device with reductant only when its temperature is within its different operating temperature range; and reducing the level of dosing of the first SCR device when requiring DPF regeneration.

    Abstract: The present disclosure relates to a heating system for an exhaust gas treatment system. The heating system comprises a first heating element comprising a receiving surface for receiving a reductant fluid and a second heating element, which may surround the first heating element. The second heating element may be a thermochemincal or thermophysical device. In a first mode of operation the second heating element is arranged to receive thermal energy from engine exhaust gas. In second mode of operation the second heating element transfers thermal energy to heat the first heating element.

    Abstract: The engine boosting system includes an engine having an intake manifold, exhaust manifold and exhaust gas recirculation loop fluidly connected therebetween. A boost circuit including a storage vessel is in fluid communication with the intake manifold and with the exhaust manifold. A throttle is located downstream of the exhaust manifold, the exhaust gas recirculation loop, and the boost circuit. A connection between the boost circuit and the intake manifold is independent of a connection between the exhaust gas recirculation loop and the intake manifold.

    Abstract: A method of controlling exhaust gas temperature in an engine system including an internal combustion engine, a supercharger, a supercharger bypass arrangement and an exhaust aftertreatment module. The supercharger bypass arrangement is operable to selectively direct intake gas substantially to the supercharger or to direct the intake gas to the engine substantially bypassing the supercharger. The method includes determining an engine load and selectively controlling operation of the supercharger and supercharger bypass arrangement, based upon the engine load, to control the temperature of the exhaust gas to maintain it in a predetermined temperature range associated with the exhaust aftertreatment module.
