Problems solved by technology

However, these humidity sensors cannot distinguish between normal condensate in the cylinder and hazardous water ingress, which in large internal combustion engines may arise due to the stack effect of the exhaust system

Embodiment Construction

[0027] figure 1 An internal combustion engine 1 is shown schematically with a drive shaft 5 and a gear wheel 8 arranged thereon. In order to start the internal combustion engine 1, a starter gear 7 connected to the starter 2 is engaged in a known manner via a coupling mechanism 11 not shown here and then meshes with the gear 8 of the internal combustion engine 1 (see image 3 ). The starter 2 is in this case an electric starter which is supplied with voltage or current via an energy source in the form of a voltage source 14 . In order to control the voltage supply to the electric starter 2 , a switch 13 is arranged between the voltage source 14 and the starter 2 , which switch can be controlled via a control device 6 .

[0028] The rotational speed n and / or the angular velocity ω and / or the angular acceleration α of the drive shaft 5 of the internal combustion engine 1 is detected by a measuring device 9 and transmitted to the control device 6 . The measuring device 9 can b...

Abstract

The invention relates to a method for starting an internal combustion engine (1), particularly a stationary gas engine, which is driven by at least one starter motor (2). The starting process is interrupted once the starter motor (2) has been started if the angular acceleration (a) of the internal combustion engine (1) remains below a predefinable acceleration value and / or if, within a predefinable first time period (tA), the actual rotational speed (n) remains below a predefinable first rotational speed threshold value (nA) and / or if, within a predefinable second time period, the average rotational speed of the internal combustion engine (1) remains below a predefinable second rotational speed threshold value. The starter motor (2) is designed as a pneumatic starter motor (2) and the compressed air supply thereof is controlled by a compressed air valve (3) which can be switched between a fully opened position and a fully closed position, the pneumatic starter motor (2) being started by the compressed air valve (3) being fully opened.

Description

technical field [0001] The invention relates to a method for starting an internal combustion engine, in particular a stationary gas engine, wherein the internal combustion engine is driven by at least one starter motor, if the angular acceleration of the internal combustion engine remains below a predeterminable acceleration value, and / or The actual speed remains below a first predeterminable speed limit value for a first predeterminable time, and / or the average speed of the internal combustion engine remains below a second predeterminable speed for a second predeterminable time. Below the speed limit value, the starting process is aborted after the starter is turned on. [0002] Furthermore, the invention relates to a starting system for starting an internal combustion engine, in particular a stationary gas engine, the starting system having at least one starter to which energy can be supplied from an energy source, wherein the starter is connected to the A drive shaft of th...
