Starting device for gas internal combustion engine

Abstract

The object of the present invention is to provide a starting device for a gas internal combustion engine, which discharges the unburned gas remaining in the gas internal combustion engine and the exhaust passage when the gas internal combustion engine is ignited and started, so as to further prevent the safety of abnormal combustion of the gas internal combustion engine. To improve safety, damage prevention and long-term reliability, the starting device of the gas internal combustion engine (1) with an air starting device (30) is characterized in that it has: a speed detection device of the gas internal combustion engine (1); according to the gas internal combustion engine (1) The sequence of ignition timing is the compressed air introduction device (5) that supplies compressed air to each cylinder; the compressed air supply device (3) that supplies compressed air to the compressed air introduction device (5); the operator can set the threshold value of the cumulative rotation speed arbitrarily The accumulative rotation speed setting device (21), and the control device (2) for stopping the supply of compressed air by the compressed air supply device (3) when the rotation speed detected by the rotation speed detection device reaches the set cumulative rotation speed.

Description

technical field [0001] The invention relates to a starting device for a gas internal combustion engine with an idle air rotation device. Background technique [0002] In subchamber-type lean premixed gas internal combustion engines (hereinafter; referred to as gas internal combustion engines), in order to check the cylinder before operating the air starter, ensure the lubrication of the cylinder and the sliding surface of the piston sliding in the cylinder, and In order to reduce the trouble of starting the standard, there is a starting method that uses compressed air (not containing fuel gas) into the cylinder to rotate the gas internal combustion engine with idle air. [0003] During idle air rotation, when the start command (manual) of the air starter is issued, first, the idle air rotation starter valve is opened and the fixed rotation is completed, the air starter operates, and when the gas internal combustion engine reaches a certain speed, the gas internal combustion ...

AI Technical Summary

Problems solved by technology

[0006] In this situation, when the gas internal combustion engine is switched to fuel gas ignition, the remaining combustion gas will burn abnormally, causing damage to the gas internal combustion engine and the exhaust passage.
