A pump module includes a pump section that discharges evaporated fuel generated in a fuel tank to an intake path of an internal combustion engine. The pump module also stores correction information for correcting a rotation speed of the pump section based on a difference between a reference discharge characteristic of a reference pump section at a predetermined rotation speed and a discharge characteristic of the pump section at the predetermined rotation speed.

A process is provided for commissioning a particulate filter for the exhaust system of a device powered in whole or in part by an internal combustion engine. The process improves the filtration efficiency of an uncarbonized or decarbonized particulate filter through a single deposition of metal oxide particles via a gas stream.

An internal combustion engine in which a fuel reforming operation in a fuel reformation cylinder is not executed when a gas temperature of a fuel reformation chamber at a time point when a piston in the fuel reformation cylinder reaches a compression top dead point is estimated to fall short of a reforming operation allowable lower limit gas temperature set based on a lower limit value of a reforming reaction enabling temperature. For example, fuel is supplied from an injector so that an equivalence ratio in the fuel reformation chamber is less than 1. Alternatively, the fuel supply from an injector is stopped. This way, a supply of non-reformed fuel from the fuel reformation cylinder to an output cylinder can be avoided, and knocking in the output cylinder can be avoided.

A ship propulsion system comprises at least one internal combustion engine with a combustion chamber for burning a fuel and a turbocharger with a compressor in an intake tract of the internal combustion engine. The ship propulsion system further comprises an electrolysis device, which produces hydrogen and oxygen gas, which are added on a pressure side of the compressor and conducted to the internal combustion engine. Moreover, a water tank and an alcohol tank are connected to a pressure side of the compressor in order to add water and alcohol to the charge air.

A vehicle system storing an aqueous solution includes: a first compartment; a second compartment; a module that includes a feed pump unit connected for pumping aqueous solution from the first compartment to a feed outlet; and a jet pump having a suction inlet, a pressure inlet and an outlet. The feed pump unit is further connected for pumping aqueous solution along a flow path from the first compartment through the feed pump unit, through the pressure inlet of the jet pump to the outlet of the jet pump. A heater heats the flow path. The suction inlet is connected to a suction line that receives the aqueous solution from the second compartment. The outlet of the jet pump returns aqueous solution from the suction inlet and from the pressure inlet to the first compartment.

A system and method is provided that introduces oil droplets into the combustion chamber of a lean burn natural gas engine via dedicated channels located in the cylinder head and a valve seat insert for providing multiple distributed sources of ignition in addition to the spark plug based ignition system.
