Safety of vehicles employing an electrolysis generator is improved by a rollover abatement system.

HHO gas is introduced to a diesel particulate filter to improve combustion of a fuel to aid in regeneration.

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

An HHO gas stream for use in an internal combustion engine is heated by heat exchange from with an exhaust gas stream from the internal combustion engine.

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

Injection of HHO gas to plural injection points about an internal combustion engine is controlled based on combustion timing parameters.

HHO gas is distributed proximate combustion chambers of a diesel engine and to a diesel particulate filter regeneration system.

An ultra low quantity of HHO gas is introduced to an internal combustion engine to improve fuel economy and/or reduce engine-out emissions, for example in a vehicle or generator.

A burner for an exhaust gas tract that can be flowed through by exhaust gas of an internal combustion engine includes a combustion chamber in which a mixture of air and liquid fuel is to be ignited and combusted and an inner swirl chamber that can be flowed through by a first part of the air and causes a turbulent flow of the first part of the air. The swirl chamber has a first outflow opening that can be flowed through by the first part of the air flowing through the inner swirl chamber and via which the first part of the air can be removed from the inner swirl chamber. The burner further includes an introduction element that can be flowed through by the liquid fuel and via which the fuel can be introduced into the inner swirl chamber.

A controller for an internal combustion engine is configured to be used in a vehicle to control the vehicle. The vehicle includes an internal combustion engine that is provided with an exhaust purifier and a generator that converts rotation power of a crankshaft of the internal combustion engine into electric power. The exhaust purifier includes a heater configured to generate heat by consuming electric power, a filter configured to collect particulate matter from an exhaust gas, and a catalyst arranged at an upstream side or downstream side of the filter and subjected to heating by the heater. The controller is configured to perform an increase process for increasing electric power generated by the generator by increasing electric power consumed by the heater on condition that a regeneration request for the filter is issued.
