An internal combustion engine comprising: a main combustion chamber comprising at least one intake valve and at least one exhaust valve, wherein at least one intake port fluidically connected to an intake manifold is configured to supply an air and/or an air-fuel-mixture to the main combustion chamber via the at least one intake valve, and a pre-chamber which is in fluid connection with the main combustion chamber, wherein the pre-chamber is in fluid connection with the intake port and/or the intake manifold through a supply line, wherein at least one fuel injector is configured to enrich the air and/or air-fuel-mixture supplied to the main combustion chamber to have a lower ignition delay than an air-fuel-mixture supplied to the pre-chamber and/or air or air-fuel-mixture can be supplied to the pre-chamber to have a higher ignition delay than an air-fuel-mixture supplied to the main combustion chamber.

Internal combustion engine and a method for operating an internal combustion engine

Piston for an internal combustion engine, preferably a gas engine comprising a pre-chamber, comprising a piston crown limiting the piston on a side facing a cylinder head when the piston is arranged inside an internal combustion engine, wherein the piston crown comprises at least one piston bowl which has a lower surface level than a radial edge region of the piston crown, wherein the piston bowl comprises a depth (d), which is defined by the distance between the radial edge region and the lower surface level of the piston bowl measured parallel to central elevation which has a height (H), wherein the height (H) of the central elevation equals the depth (d) of the piston bowl plus/minus 50%, preferably 20%, of the depth (d) of the piston bowl.

Piston and internal combustion engine having such a piston

A pre-chamber component for an internal combustion engine includes a chamber for accommodating an air-fuel-mixture to be ignited, wherein the pre-chamber component includes a first opening into the chamber for arranging an ignition device, in particular a spark plug, and a second opening for introducing the air-fuel-mixture in the form of a mixture flow into the chamber. The pre-chamber component includes a mixture flow guiding device, which is shaped such that the mixture flow of the air-fuel-mixture in the chamber is oriented substantially transversely with respect to a longitudinal axis from the second opening of the chamber to at least a part of the chamber adjacent to the first opening and/or in the form of a turbulent flow.

Pre-chamber for an internal combustion engine and combustion engine

Internal combustion engine with at least one turbocharger having a compressor, a bypass valve by means of which the compressor can be bypassed by at least a partial flow of a fuel mixture provided for the combustion, and a control or regulating unit connected to the bypass valve for regulating or controlling a degree of opening of the bypass valve, whereby the control or regulating unit is designed to open and/or at least partially keep open the bypass valve when starting the internal combustion engine.

Internal combustion engine and method for starting an internal combustion engine

A method of operating an internal combustion engine with at least one piston-cylinder unit, and preferably a plurality of the piston-cylinder units, whereby, in a detection mode of the internal combustion engine one or more knock-promoting measures are taken until knocking has occurred in at least one piston-cylinder unit, and the measure(s) is/are intensified until a termination criterion is reached, whereby it is detected in which of the piston-cylinder units knocking has occurred, and whereby, in piston-cylinder units detected as knocking, the ignition time for a normal operating mode of the internal combustion engine is retarded.

Method for operating an internal combustion engine

An internal combustion engine with a cylinder head and at least one piston-cylinder unit, in which, in a cylinder, a piston can be moved between a bottom and a top dead center position, where, in the cylinder, between the piston and the cylinder head a main combustion chamber is formed, which communicates with a prechamber which has a prechamber gas valve, and where the intake and outlet valves of the main combustion chamber are actuated by an actuator, where the prechamber gas valve is connected to a source for a gas-air mixture and the prechamber charge consists of a gas-air mixture with a lambda higher than 1.2, preferably higher than 1.5 and particularly preferably higher than 1.7, and the actuator is configured such that the intake valve closes before the piston reaches the bottom dead center position, where the piston is designed as a flat piston.

Internal combustion engine

A method of starting up a thermoreactor arranged in an exhaust gas flow of an internal combustion engine includes igniting combustion gas by spark ignition in at least one cylinder of the internal combustion engine. The exhaust gas resulting from the combustion of the combustion gas is fed at least partially to the thermoreactor as an exhaust gas flow. The temperature of the exhaust gas resulting from combustion of the combustion gas is increased by the moment in time of the spark ignition being selected later in comparison with a present moment in time.

Method of starting up a thermoreactor

A spark plug includes a center electrode and a ground electrode. The center electrode is arranged relative to the ground electrode in such a way that the spark gap extends between the ground electrode and the center electrode. The spark gap is surrounded by a wall, wherein the wall has a recess or hole, which is designed in such a way that a feeler gauge can be inserted between the center electrode and the ground electrode.
