摘要： A method for deposit mitigation in a gaseous fuel injector that introduces a gaseous fuel through a gaseous fuel orifice directly into a combustion chamber of an internal combustion engine includes at least one of a) reducing the ago length of the gaseous fuel orifice by substantially between 10% to 50% of a previous length of a previous gaseous fuel orifice showing deposit accumulation above a predetermined threshold; b) providing the gaseous fuel orifice with an inwardly and substantially linearly tapering profile; c) determining deposit mitigation is needed; and performing at least one of the following deposit mitigation techniques i) increasing gaseous fuel injection pressure wherein deposit accumulation is reduced during fuel injection; and ii) decreasing gaseous fuel temperature wherein a rate of deposit accumulation is reduced; and d) injecting compressed air through the gaseous fuel orifice during shutdown of the internal combustion engine; whereby torque loss in the internal combustion engine due to deposit accumulation in the gaseous fuel orifice is reduced below a predetermined value.

摘要： A secondary fuel injection system determines (precisely) a maximum amount of secondary fuel that can be injected into a cylinder during a cycle based upon the rotational speed (RPM) of the engine. A primary fuel injection pulse width of the prior cycle and is used to determine how much heat energy was requested by an engine control module based upon the duration of the injection pulse. Secondary fuel is injected into the intake port of the cylinder after the exhaust valve closes in an amount that is calculated based upon the maximum that can be injected during the allowed calculated time of crankshaft rotation and the amount of heat energy requested in the prior cycle and to include the amount of primary fuel that is then injected into the cylinder is being reduced based upon the amount of heat energy provided by the secondary fuel that was previously injected.

摘要： An engine-driven electricity generation system can selectively use diesel and LNG as fuel by recycling a diesel engine from a scrapped vehicle and heats intake air with an electric heater to start an engine using LNG and then heats the intake air using heat from a high-temperature exhaust gas after starting the engine, thereby accelerating ignition of LNG.

摘要： An internal combustion engine including at least one combustion chamber having a main chamber and a prechamber, wherein the prechamber is in fluid connection with the main chamber via at least one bore. The at least one combustion chamber is connected to a charging path for the supply of a combustion air-fuel mixture into the combustion chamber via the charging path. A fuel intermixing region is arranged in a section of the charging path separately assigned to the combustion chamber, which fuel intermixing region is in fluid connection with the charging path on one side and with a fuel line on the other side for the supply of fuel into the fuel intermixing region via a controllable fuel valve. The internal combustion engine wherein the prechamber and the fuel intermixing region are in fluid connection with one another via a check valve.
