A dual-chamber onboard electrolysis system is configured to produce HHO gas for heavy duty trucking applications.

A honeycomb body having a cutout, an assembly including the honeycomb body, and a method of manufacturing. The method includes forming the honeycomb body having a matrix of intersecting walls that define a plurality of cells and channels extending longitudinally through the honeycomb body. A subset of the channels are plugged to create a plurality of plugged cells in a reinforcement region of the honeycomb body. Material is removed from the honeycomb body within the reinforcement region in accordance with a peripheral shape that passes through the plugged cells to form a cutout that extends an axial depth into the honeycomb body.

A dual-chamber electrolysis vessel safely stores HHO gas for use by an internal combustion engine.

A water separator includes an outer annular passage extending along a central longitudinal axis of water separator to direct an airflow along a first direction, and an inner annular passage located radially inboard of the outer annular passage and coaxial with the outer annular passage to direct the airflow along a second direction. A coalescer is located along the outer annular passage to coalesce water in the airflow. A water collector is located along the inner annular passage to collect the water. An airflow outlet is located downstream of the water collector through which the airflow exits the water separator.

A particle adhesion device includes: a holder; a chamber; a nozzle; an intake port; and a flow control member. The holder holds a filter substrate having a first end face and a second end face. The chamber is in communication with the holder and is arranged so that the first end face of the filter substrate faces a space in the chamber. The nozzle is arranged on an opposite surface of the chamber opposing to the first end face of the filter substrate, and can inject an aerosol containing particles toward the first end face of the filter substrate. The intake port is provided on the opposite surface of the chamber and can incorporate an ambient gas. The flow control member is arranged on the opposite surface provided with the intake port, and can control the flow of the ambient gas.

A particle filter assembly for a motor vehicle includes a particle filter, an exhaust-gas-conducting line which opens into the particle filter, and a secondary air supply. The secondary air supply is formed separately from the exhaust-gas-conducting line and fresh air is suppliable to the particle filter via the secondary air supply.

Disclosed are a pollutant capturer and mobilizer and method of mobilizing a polluted gaseous substance from one location towards another location and capturing one or multiple types of polluting substances, such as CO.sub.2, from an atmospheric body of polluted gaseous substance or from exhaust of vehicles, chimneys, or stacks and thereby combat the negative health, environmental, and economic impacts of the of the polluting substances on communities. Wet or dry embodiments of the pollutant capturer and mobilizer utilize wet or dry pollutant capturing components, respectively, to capture one or multiple types of polluting substances from a body of polluted gaseous substance. Flow establishing devices can be used to set the body of polluted gaseous substance in motion through the pollutant capturing component. The pollutant capturer and mobilizer may also be mounted on any type of vehicles, with or without using flow establishing devices.

Timing of HHO gas injection into a 4-stroke engine is optimized based on engine operating parameters to improve fuel economy.

The disclosure relates to a method of forming a coated monolith article for the treatment of an exhaust gas. The method comprises the steps of: retaining a porous monolith article in a coating apparatus, the porous monolith article comprising a plurality of channels for the passage of an exhaust gas, each channel having a gas-contacting surface; depositing cementitious particles as a dry powder onto the gas-contacting surface of at least some of the channels; and reacting the cementitious particles with a liquid or gaseous reagent in situ within the porous monolith article to provide the coated monolith article.

An illustrated view of an exemplary air filter for reducing emissions is presented. The air filter is useful for removing toxic gases from the air surrounding a combustion engine of a vehicle is presented. The air filter is useful for scrubbing the ambient air for removal of toxic contaminants such as carbon dioxide and thus reducing harmful emissions of a vehicle. The air filter though described for a vehicle can also be used in industry settings as well as at home. The air filter is recyclable. Although a vehicle is shown, it is an example only. Other applications are possible and have been contemplated for the air filter 100 including, but not limited to, commercial applications, home applications, industrial applications, etc.
