A pressurized air vacuum cleaning device that is useful for the purpose of cleaning the inside cabin of a motorized vehicle is exhibited. The power source for the suction of the vacuum is derived from the onboard pressurized air that is commonly available on motorized vehicles such as trucks and work vehicles. A vacuum chamber is disposed in communication with the pressurized air system of the vehicle, which channels pressurized air by a venturi to create useful vacuum suction from the existing flow of air. The suction is channeled to the cabin of the vehicle, within a front pipe disposed under the floor of the cabin, which houses a vacuum hose for use by a user to clean debris from the cabin. The hose is concealed beneath a cover plate on the floor, which is lifted up by the user, simultaneously activating the suction to the vacuum hose upon lifting.

A non-polluting brake assembly comprising a caliper bracket, a rotor disc, two movable pads clamped by a caliper, the pads comprising friction material capable of releasing particles resulting from abrasion, and a suction device arranged at least partially in proximity to the caliper bracket, the suction device comprising, in proximity to each pad, a suction zone delimited by a deflector and in which a negative pressure is created, characterized in that the deflector comprises at least one portion located in an external radial position relative to the pad.

A vehicle control apparatus includes at least one electronic control unit (50). The electronic control unit detects a negative pressure that is generated in a negative pressure chamber (34) of a braking operation support device (32). The electronic control unit prohibits, based on the detected negative pressure of the negative pressure chamber, an internal combustion engine (26) from automatically stopping when determining that a driver does not perform the braking operation and that a speed of the internal combustion engine is at a threshold or higher continuously for a specified time period or longer. The negative pressure is generated in the negative pressure chamber in response to rotation of the internal combustion engine. The braking operation support device supports, with the negative pressure in the negative pressure chamber, the driver to perform the braking operation.

A vehicle includes a turbocharger, an exhaust-side variable valve, a vacuum servo device, an exhaust-side negative pressure hose, an exhaust-side check valve, a negative pressure supply valve, and circuitry. The exhaust-side negative pressure hose connects the vacuum servo device and a negative pressure extracting portion disposed in the exhaust passage. The exhaust-side check valve is disposed in the exhaust-side negative pressure hose to permit a gas flow only from the vacuum servo device to the exhaust passage. The negative pressure supply valve is provided in the exhaust-side negative pressure hose to open and close the exhaust-side negative pressure hose. The circuitry configured to control the exhaust-side variable valve to delay the valve timing with respect to an exhaust top dead center so as to generate negative pressure in the exhaust passage and to open the negative pressure supply valve while the negative pressure is generated in the exhaust passage.

A system for an engine is provided, the system comprising a vacuum pump at least partially deposed within an engine crankcase, and a fuel vapor canister coupled to an exhaust conduit of the vacuum pump via a one-way valve. By coupling the vacuum pump exhaust to the fuel vapor canister, unmetered fuel vapor flow to the engine intake may be reduced, thus decreasing engine stall events. Further, crankcase pressure may more accurately represent airflow through the crankcase via a crankcase ventilation system, thereby improving the accuracy of crankcase ventilation diagnostics.
