A dosing system that is configured to pre-dose an additive into the fuel tank of a motor vehicle before or during filling, of the vehicle fuel tank. The dosing system includes a base unit having an enclosure that includes a controller, product reservoir and a pump. The dosing system also includes a dynamic fill adapter that is attached to the filler neck of the fuel tank. The tank of base unit is fluidly coupled to the fill adapter. Removal of the cap from the fill adapter causes a predetermined dose of additive to be dispensed from the product reservoir into the fuel tank through the fill adapter.

A vehicle includes an engine to receive a cracked gas mixture. A cracker of the vehicle can receive ammonia and energy, crack the ammonia to form the hydrogen gas and a nitrogen gas, and convey the hydrogen gas to the engine. A controller for the vehicle can receive a predefined route for the vehicle. The controller can predict a future load demand of the vehicle based on the predefined route. The controller can adjust a flow rate of ammonia delivered to the cracker based on the future load demand.

A split cycle internal combustion engine comprising a compression cylinder accommodating a compression piston; a combustion cylinder accommodating a combustion piston; a crossover passage between the compression cylinder and the combustion cylinder arranged to provide working fluid to the combustion cylinder; a controller arranged to determine a peak temperature of combustion in the combustion cylinder based on a received indication of a peak temperature of combustion in the combustion cylinder; and a coolant system arranged to regulate a temperature of the working fluid supplied to the combustion cylinder; wherein, in response to determining that the peak temperature of combustion exceeds a selected threshold, the controller is configured to control the coolant system to regulate the temperature of the working fluid supplied to the combustion cylinder so that a peak temperature of combustion in the combustion cylinder is less than the selected threshold.

To atomize water injected from a water injection valve.SOLUTION: An internal combustion engine 10 includes a cylinder 12, a water injection valve 51, and a fuel injection valve 52. The cylinder 12 is formed into a cylindrical shape having a center axis C. The water injection valve 51 injects water into the cylinder 12. The fuel injection valve 52 injects gaseous fuel into the cylinder 12. An injection axial line WJ of the water injection valve 51 and an injection axial line GJ of the fuel injection valve 52 cross each other in the cylinder 12 in a cross-sectional view in a plane which is parallel to the center axis C of the cylinder 12 and includes an end of the water injection valve 51 and an end of the fuel injection valve 52.SELECTED DRAWING: Figure 3

An inert blanket system includes a reformer that produces hydrogen gas and carbon dioxide. The hydrogen gas is separated from the carbon dioxide. The carbon dioxide is ported to a vapor region of a tank to reduce the flammability of the gases in the vapor region of the tank. Excess carbon dioxide is ported to an overflow system designed to store the excess carbon dioxide for future use or to sequester the carbon dioxide.

Disclosed is an adiabatic internal combustion engine (102) including one or more cylinders (104) covered by an insulation layer (210) The engine includes one or more intake valves (108) configured to introduce a mixture of oxygen, water, and fuel into the cylinders (104) during an intake stroke. One or more pistons (106) are configured to compress the mixture with a compression ratio between 1:20 to 1:500 during a compression stroke, and expand when the water converts to high-pressure steam after combustion during a power stroke. One or more exhaust valves (110) expel combustion products during an exhaust stroke. The engine may include a water recovery unit (112), an oxygen generation unit (114), and an oxygen storage unit (116). A vehicle (100) including the engine and a method (300) for operating the engine are also disclosed.
