An air-vapor engine which exhibits one or more cylinders and a piston located therein, by which a stroke movement can be performed. Furthermore, the air-vapor engine has an injection nozzle and a prechamber. The prechamber is arranged between the injection nozzle and the cylinder, a fuel fluid is introduced into the prechamber from the injection nozzle. Compressed air from the cylinder can be received by the prechamber. This enables the stroke movement of the cylinder. In addition, the cylinder is connected to a condenser via an outlet valve such that the air-vapor mixture or the vapor of the air-vapor mixture condenses and is present in the condenser as condensate. The condenser and the injection nozzle are in flow connection. This means that the air-vapor engine exhibits a circuit, resulting in efficient operability.

To disclose embodiments that relate generally to systems and methods of operating internal combustion (IC) engines, and more specifically to systems and methods of starting compression ignition (CI) engines when a surrounding environment is significantly colder than a normal operating temperature of the engine (i.e., "cold-start").SOLUTION: In some embodiments, the CI engine can include an ignition-assist device. In some embodiments, a method of operating the CI engine during cold-start can include opening an intake valve to draw a volume of air into the combustion chamber, moving a piston from a bottom-dead-center position to a top-dead-center position in a combustion chamber at a compression ratio of between about 15 and about 25, injecting a volume of fuel, the fuel having a cetane number of less than about 30, closing the intake valve, and combusting substantially all of the volume of fuel.SELECTED DRAWING: Figure 2

This invention belongs to the field of methanol generator technology and relates to an artificial intelligence-based methanol generator set. By analyzing the operating status of the target methanol generator set, this invention helps to promptly detect anomalies and predict potential faults, ensuring the stable operation of the target methanol generator set. By predicting the load demand of the target methanol generator set during the predicted time period, it helps to ensure its fuel supply and avoid the risk of insufficient power generation or shutdown due to fuel shortages. By analyzing the current fuel supply matching degree of the target methanol generator set, it helps to dynamically adjust its power generation, improving its power generation efficiency and energy utilization rate. By obtaining the actual load demand of the target methanol generator set during the current time period, it helps to quickly adjust its output power and the charging and discharging strategy of the energy storage system, helping to smooth power fluctuations and ensuring the stable operation of the power system.
