An internal combustion engine includes an internal combustion engine interior and a lubricant disposed in the internal combustion engine interior. The lubricant lubricates a component disposed in the internal combustion engine interior and the lubricant is a water-containing lubricant. In an embodiment, the internal combustion engine interior is fluidically connected to an environment surrounding the internal combustion engine by a ventilation device where the ventilation device has a semipermeable membrane which is impermeable to water and water vapor.

A system for storing and supplying water to an internal combustion engine of a motor vehicle with a reservoir (1) for the water, with at least a delivery pump (5) for the water, and with at least a pipeline system comprising at least a feed line (4) to a consumer which is preferably designed in the form of at least a metering unit, and at least a return line (9) into the reservoir (1) as well as with means for demineralizing the water which are disposed inside the reservoir (1) or in the pipeline system.

The invention is a pump engine developed for the purpose of launching and pumping capsules in a hydraulic pipeline. The engine operates on the combustion and explosion of a mixture of fuel and oxygen bearing gases against a liquid piston that passes through a dynamic current turbine. The rotation of the turbine maintains a constant direction of rotation through the oscillation of the water column, and drives a special rotor to feed capsules from a hopper into the pipeline, while the liquid piston pushes them into the pipeline and applies the necessary pressure. The turbine also drives the necessary auxiliaries such as alternator and camshaft for water valves and air inlet and exhaust valves. The pump engine is built in single cylinder or multiple cylinders in duplex and fourplex configurations.

A fuel pump for a liquid fuel water injection system of a motor vehicle is provided. The fuel pump includes a low-pressure pump that mixes water from a water tank of the motor vehicle with liquid fuel from a fuel tank of the motor vehicle to a liquid fuel water emulsion and provides the liquid fuel water emulsion at a low pressure. A high-pressure pump is in fluid communication with the low-pressure pump and compresses the liquid fuel water emulsion from the low pressure to a high pressure for injecting the liquid fuel water emulsion into an internal combustion engine of the motor vehicle via an injection rail of the motor vehicle. A pump drive drives the low-pressure pump and the high-pressure pump synchronously with a pump frequency independently from an engine speed of the internal combustion engine of the motor vehicle.

Described are methods for shortening the combustion delay of ammonia fuels and reducing the amount of NO formed during the combustion process. The methods include mixing ammonia with hydrogen peroxide and water to form a fuel mixture and then combusting the fuel mixture. Methods of powering an internal combustion engine with ammonia fuels are also described.

An energy transfer machine includes a piston and cylinder. The piston can have a rocking motion as it enters and exits the cylinder, for example due to one being on a rotor and the other on a stator. The piston and cylinder form a primary chamber, and as they move relative to each other can form a seal separating the primary chamber into first and second sub-chambers which then unseals before the piston exits the cylinder. The first sub-chamber may reach a maximum geometric compression ratio, for example for the purpose of compression ignition, before the unsealing of the sub-chambers.
