A nebulizer system for a motor vehicle may include a tank for a liquid, a nebulizer chamber, and a filter system capable of filtering the liquid contained in the tank for the liquid before it passes into the nebulizer chamber. The nebulizer chamber may have a nebulizer nozzle provided with an acoustic wave output device such that the liquid from the tank forms a mist of droplets of the liquid. The mist is intended to pass into a passenger compartment of the motor vehicle. Additionally, the nebulizer system may have an input module for air. The inlet module may have an air injection volute capable of channeling the air in the direction of the internal volume of the nebulizer chamber.

An odor reproducing apparatus of a HVAC system for the vehicle may include an odor reproducing device configured to reproduce and evaluate odor by applying a HVAC system module, a heat exchange outdoor device mounted at one side of the odor reproducing device to control a temperature and humidity of an experimental space, and a control device mounted at one side of the odor reproducing device and the heat exchange outdoor device to control an operation of the odor reproducing device and an operation of the heat exchange outdoor device to implement a field environment and vehicle conditions for evaluating an odor improvement effect of the HVAC system reflecting an odor reduction technology.

A humidification device includes a humidification section that humidifies taken-in air and a cover that covers the humidification section. A space is provided between the humidification section and the cover. A supply port for sending out humidified air humidified by the humidification section is further provided. The space communicates with the supply port, and the humidified air flows through the space, thereby utilizing air in the space as a heat insulation layer.

A humidifying device for a vehicle has a humidity detection part, a blower, a non-water-supply humidifier, and a controller. The humidity detection part detects a humidity in a vehicle compartment. The blower draws, as an intake air, an inside air in the vehicle compartment and an outside air outside the vehicle compartment at a specified ratio and blows the intake air toward the vehicle compartment. The non-water-supply humidifier collects water included in the inside air and supplies a humidified air, which is humidified using the water, toward a specified area in the vehicle compartment. The controller sets the specified ratio between the inside air and the outside air and controls an operation of the non-water-supply humidifier. The controller controls the blower to draw at least the inside air, when the non-water-supply humidifier is operated, and when a humidity in the vehicle compartment is lower than a specified humidity.

A car humidifier, which includes a base, a water tank connecting to the base, a waterproof washer for the water tank, an absorbent sponge stick extended between the base and the water tank, an atomization film supported by a bottom support in the base having direct contact between the absorbent sponge stick and the water tank, a waterproof ring for the bottom support, a circuit board electrically connected to the atomization film, an upper case having a spray opening communicate with the atomization film and connected to the base, a positioning seat for rotation mounted to two sides of the base, a cigarette lighter plug connected to the circuit board, a positioning plug coupling to the positioning seat extended on top of the cigarette lighter plug, thereby unnecessary wiring is eliminated. This design is simple, elegant, convenience and easy for use.

An air conditioning system for an interior of a vehicle, which has at least one cooling unit as at least one component. The at least one cooling unit has thermally conductive composite yarn and carrier material, which has phase change material. The carrier material is woven into the composite yarn. The phase change material is designed to absorb heat from the interior above its melting point.

A vehicle climate control system includes a heating, ventilation, and air conditioning (HVAC) system where condensate from the system is conveyed to a misting device disposed at an air-conditioned outlet in the cabin of the vehicle. The misting device can be arranged at the exit of the air-conditioned outlet such that conditioned air is conveyed by the HVAC ducting and mixes with the mist generated by the misting device at the air-conditioned outlet. The mist may be scented using an injection device that pumps a fragrant fluid into the misting device along with the condensate. Prior to conveying the condensate to the misting device, the condensate may be pumped through bacteria and sediment filter media providing a clean supply of condensate to the misting device. Positioning the misting device at the air-conditioned outlet helps prevent mold or debris from being trapped in the HVAC system or ducting.

A method, device and system for operating internal combustion engines with an increased pressure ratio and vehicle with this system. Internal combustion engines have a technically restricted pressure ratio, which limits the thermal efficiency. Gas turbines have so far had a maximum pressure ratio of 33:1, diesel engines have compression ratios of up to 23:1. An oxidizer is fed into the combustion chamber in (cold) liquefied condition under very high pressure. The fuel is also supplied in liquid form under high pressure. The pressure ratio of the oxidizer pump is 200, 500 or more. In the combustion chamber, the oxidizer and fuel react and expand to more than a thousand times the liquid volume. Depending on the fuel used, an expansion machine with a pressure ratio of around π=500 or more or an equivalent expansion ratio of ε=85 or more can be implemented.
