Power systems and enclosures having a configurable cooling air flow are disclosed. The power system includes an enclosure; an air inlet location, a first air outlet location, a second air outlet location, a fan assembly, and one or more relocatable covers to obstruct the first and second air outlet locations. The air inlet location may be at a first location on an exterior of the enclosure to permit intake of air from the exterior of the enclosure to an interior of the enclosure. The first air outlet location may be at a second location on the exterior of the enclosure to expel air taken in through the air inlet location, while the second air outlet location at a third location on the exterior of the enclosure to expel air taken in through the air inlet location.

Methods and systems are provided for a valve for controlling the flow of a fluid medium in a coolant circuit of an internal combustion engine. The valve is configured to react to the temperature of the coolant via an expansion element and to the charge pressure in the intake tract via a pressure-sensitive actuator.

An engine control apparatus and an engine control method for a vehicle are disclosed. The engine control apparatus includes: an integrated thermal management valve in which an opening degree of a plurality of valves is adjusted by rotation of a cam; a storage to store an opening degree of the integrated thermal management valve based on a road slope and a transmission gear value; and a controller that controls the opening degree of the integrated thermal management valve by using an engine revolutions per minute (RPM) and an accelerator pedal value. In particular, when the accelerator pedal value is smaller than a predetermined threshold, the controller controls the opening degree of the integrated thermal management valve based on the road slope and the transmission gear value.

A fluid flushing machine for a vehicle engine component uses a pre-heated cleaner/fluid to increase the effectiveness of the cleaning procedure and reduce the time needed to clean the component. The invention is designed to clean air charged coolers, EGR valves, EGR coolers, and other components that over time have become contaminated with carbon build up, oil, and debris. The machine of the present invention has the option to direct heated cleaning fluid through the vehicle engine's cooling system to remove carbon build up, oil, and debris in the vehicle's EGR valve and cooler component. The machine of the present invention is adapted to perform the operation in an engine-off condition by incorporating an integrated or external electronic device to open the vehicle's EGR valve to allow the cleaning fluid to flow through the engine while it is turned off.

A method of rapidly cooling a high temperature vehicle coolant is disclosed. The method includes determining a coolant temperature lowering entry condition by detecting information on the coolant temperature, an engine speed, and a gear state and determining whether the coolant temperature needs to be rapidly lowered on the basis of the detected information; and changing a number of gear stages by adjusting the number of gear stages of a transmission to be reduced to a specific number of gear stages when the coolant temperature needs to be rapidly lowered in the determining of the coolant temperature lowering entry condition, so that the cooling fan is driven by driving the fan belt through a crank damper pulley using the increased engine speed according to the reducing adjustment of the number of gear stages.

Multi-compartment liquid reservoir (10), for a motor vehicle, including a first fluid compartment (14) equipped with a fluid inlet (18) and with a fluid outlet (22), and a second fluid compartment (16) equipped with a fluid inlet (20) and with a fluid outlet (24), the reservoir including a liquid-filling neck (12) and the compartments in fluid communication via at least one passage (30) allowing one of the compartments to be filled via the other of the compartments, the reservoir further including at least one shut-off system (44), able to move between a first position of opening of the at least one passage and a position of closure of the at least one passage, wherein the shut-off system is configured to adopt the first position by default and in the free state, and to be urged into the second position when the reservoir is in operation.

A power pack for converting waste heat from exhaust gases of an internal combustion engine to electrical energy includes a working fluid loop fluidly connecting an evaporator, an expander, a condenser and a pump. The power pack also includes a working fluid tank fluidly connected to the working fluid loop between an outlet of the condenser and an inlet of the pump. The working fluid tank has a single working fluid port operable to receive working fluid from the outlet of the condenser and to supply working fluid to the inlet of the pump. The power pack also includes a power pack control unit in communication with the working fluid tank. The power pack control unit is operable to change a pressure of the working fluid in the working fluid loop at the inlet of the pump by changing the pressure of the working fluid in the working fluid tank.

A waste heat recovery system in thermal communication with an exhaust conduit of an internal combustion engine of a vehicle includes a condenser. The condenser includes a working fluid conduit configured to connect to a working fluid loop of the waste heat recovery system and a coolant fluid conduit configured to connect to a coolant fluid loop used to cool the internal combustion engine of the vehicle. The coolant fluid conduit includes a coolant fluid inlet and a coolant fluid outlet. The waste heat recovery system also includes a coolant fluid bypass fluidly connected between the coolant fluid inlet and the coolant fluid outlet. The coolant fluid bypass includes a coolant fluid control valve configured to vary a portion of the volume of coolant fluid that flows through the coolant fluid bypass based on a temperature of a working fluid in the working fluid loop.
