Problems solved by technology

Since the corresponding cylinder can only be supplied with an ignitable mixture via its open intake valve, the restarting of a stopped motor without a starter is proven for combustion motors provided only with an intake manifold injection mechanism for more complex

Embodiment Construction

[0028] figure 1 A motor system 1 is shown schematically with a combustion motor 2 which, in the exemplary embodiment shown, has four cylinders 3 . Cylinders 3 are operated in four-stroke mode and supplied with fuel-air mixture via intake manifold injection system 16 . Fresh air is supplied to the intake manifold injection device 16 via an air supply system 14 , the amount of fresh air delivered being regulated by a throttle valve 12 integrated into the air supply system 14 . Said intake pipe injection device 16 is connected to an air delivery system 14 in the form of four intake pipes 11 for delivering fresh air in a cylinder-specific manner, providing injection to each intake pipe in the vicinity of the respective intake valve 5 The valve 12 can correspondingly inject fuel quantities into the four intake pipes. Combustion motor 2 can be designed as a non-auto-ignition combustion motor, in particular an Otto motor.

[0029] Cylinders 3 each have a conventional piston, which...

Abstract

The invention relates to a method for restarting a multi-cylinder combustion motor (2) with an intake manifold injection mechanism (16) without externally delivered torque, wherein the crankshaft of the combustion motor (2) ( The rotation of 4) is initiated by igniting the ignitable mixture in the first cylinder (3) which is in its expansion phase at the beginning of the restart, and the second cylinder (3) which is in its compression phase at the beginning of the restart The ignitable mixture is then decompressed towards the intake manifold (11) by opening the intake valve (5) of the second cylinder (3), which was closed before restarting, until a predetermined decompression is reached. The end angle is pressed and the ignitable mixture remaining in the second cylinder (3) is subsequently ignited in order to continue the rotation.

Description

technical field [0001] The invention relates to a method for restarting a multi-cylinder combustion engine with an intake manifold injection system without an externally delivered torque. An electronic controller, a computer program and a machine-readable storage medium are also subjects of the invention. Background technique [0002] DE 10 2013 220 637 A1 mentions a method for restarting a multi-cylinder combustion motor with direct injection without an externally supplied torque, ie for implementing a starterless The method of starting the motor. According to a known method, the combustion motor is activated in the standstill state of the combustion motor by injecting a fuel quantity directly into a cylinder of the combustion motor in its expansion phase and igniting an ignitable mixture. rotation of the crankshaft of the engine and continues the rotation of the crankshaft by subsequently injecting fuel into the other cylinders of the combustion motor. With the direct i...
