Methods and systems are provided for an ultrasonic wave generator within a vehicle emissions control system. In one example, a frequency of ultrasonic waves may be applied to a fuel vapor canister, the frequency adjusted in response to an estimate of hydrocarbon distribution within a vapor canister received from temperature and hydrocarbon sensor outputs.

A motor response control method in a variable charge motion system in which a VCM motor is differentially controlled by a PWM duty regardless of back pressure of intake air in an intake manifold when a current engine rotation speed in revolutions per minute is less than a specific engine rotation speed in revolutions per minute in a VCM position learning state by a controller whereas the VCM motor is differentially controlled by the PWM duty based on the back pressure of intake air in the intake manifold when the current engine rotation speed in revolutions per minute is greater than the specific engine rotation speed in revolutions per minute.

A mixing valve of an exhaust-gas recirculation device of an internal combustion engine of a motor vehicle includes an intake flap and an exhaust-gas flap coupled rigidly to one another via a coupling rod. During driving of the exhaust-gas flap, the intake flap is first pivoted in the opposite direction via the coupling rod. The exhaust-gas flap and intake flap are pivoted in the same direction only above a provided pivoting angle.

A method of improving cold starting of an internal combustion engine of a vehicle. The vehicle is equipped with an on-board microwave generation system that generates and delivers microwaves into the combustion chamber of each cylinder via an antenna associated with each cylinder. The microwaves are delivered immediately prior to cold start of the engine, causing the combustion chamber and interior elements of the chamber to be warmed.

A leak detection apparatus performing leak detection with suppressing energy consumption includes a leak detection section performing the leak detection of detecting occurrence or non-occurrence of purge gas leakage in an evaporative-emission pipe based on a tank inside pressure measured by a pressure sensor by evaporating a fuel, which has been atomized by an atomizer or an ultrasonic wave generator, by a heater in a state in which the evaporative emission pipe is air-tightly sealed by a purge valve and an atmosphere open/close valve.

A thermo-kinetic reactor and process where a micro-packet of a mixture of air, fuel, and water are exposed to high energy ultrasound, a high frequency electromagnetic field, and thermal energy self-generated to initiate micro-nuclear fusion. A reaction chamber with a nozzle and adjacent resonance chamber form micro-packets and micro-explosions. The micro-explosions form high negative pressure bubbles which implode accelerating fusible elements towards a center forming a nucleus generating kinetic energy.

A fuel supply apparatus for an internal combustion engine includes: a fuel tank that stores a liquid fuel; a mixed gas space defining portion provided outside the fuel tank and defining a mixed gas space that is filled with a mixed gas containing an evaporated fuel and air; a fine bubble fuel generator including a liquid fuel inlet that communicates with a liquid region of the fuel tank and a mixed gas inlet that communicates with the mixed gas space defining portion and configured to generate a fine bubble fuel containing fine bubbles of the mixed gas from the liquid fuel supplied from the fuel tank and the mixed gas supplied from the mixed gas space defining portion; and a fuel supply unit that supplies the fine bubble fuel generated by the fine bubble fuel generator to the internal combustion engine.

A fuel delivery injector includes a housing, an end cap including an inlet port fluidly coupled to a cavity to direct fuel vapor and liquid fuel into the cavity and an outlet port fluidly coupled to the cavity to direct fuel vapor and liquid fuel out of the cavity, a magnetic assembly fixedly positioned within the cavity, and a pumping assembly including a bobbin and a piston. A return spring is coupled to the pumping assembly to bias the pumping assembly to a home position and a valve assembly including a biasing spring is positioned between an inlet chamber and an outlet chamber. The liquid fuel entering the housing through the inlet port flows from the inlet port to the cavity and fuel vapor entering the housing through the inlet port is directed through a conduit to the outlet port.
