TLDR
In this paper, a suction gas heater control device for an engine comprising first detector for detecting when the engine is brought into complete firing, and for providing a signal in response thereto, a first timer coupled to the output of the first detector, and a second detector for continuously providing a first operating signal for a predetermined period of time after a first period, starting with the beginning of the inputting of a signal from first detector and ending with the stopping of the signal from the first detectors.
Abstract
A suction gas heater control device for an engine comprising first detector for detecting when the engine is brought into complete firing, and for providing a signal in response thereto; a first timer coupled to the output of the first detector for continuously providing a first operating signal for a predetermined period of time after a first period of time, the first period of time starting with the beginning of the inputting of a signal from the first detector and ending with the stopping of the signal from the first detector; a second detector for detecting engine temperature and for providing a second operating signal when the engine temperature is lower than a predetermined level; and a judgement circuit means coupled to the first timer and the second detector for providing a signal for operating a suction gas heater, when the first operating signal is applied thereto and when the second operating signal which indicates that at least one of the temperature of the engine is lower than a predetermined level.

Automatic flame-starting installation in particular for multi-fuel internal combustion engines

TL;DR: In this article, a fully automatic flame-starter installation, especially for multi-fuel internal combustion engines, is presented. But the starting of the operation of the flame- starter installation takes place simultaneously with the start of the internal combustion engine by way of a starter switch while the flame starter installation is turned off automatically depending on the requirements of the starting conditions of the engine and, if necessary, automatically starts up again.
