摘要： The temperature of the working gas in the heating chamber of each of a number of cylinders is continuously measured. An electronic selection circuit selects the lowest measured temperature as a control parameter by which the speed of a blower in the common air supply is controlled for providing an air flow proportional to blower speed. A pressure-detecting device measures the air flow through a pressure converter provides an electrical signal that normally controls the valves of the respective fuel supplies for the combustion chambers of the cylinders, but a monitoring device for each cylinder compares the measured working gas temperature with a pre-set maximum value so that when the maximum value is exceeded, the fuel supply valve is changed over to control by the output of the monitoring device, to reduce the fuel supply until the maximum temperature is no longer exceeded in that cylinder. For still a higher temperature of the working gas in any cylinder, determined by another sensor, a general shutdown valve reduces the common fuel supply. An auxiliary air supply provides atomizing air for fuel injection.
摘要翻译：连续地测量多个气缸中的每一个的加热室中的工作气体的温度。电子选择电路选择最低测量温度作为控制参数，通过该参数控制共用空气供应中的鼓风机的速度以提供与鼓风机速度成比例的空气流。压力检测装置测量通过压力转换器的气流提供通常控制用于气缸的燃烧室的相应燃料供应的阀的电信号，但是每个气缸的监测装置将测得的工作气体温度与预设最大值，使得当超过最大值时，通过监视装置的输出改变燃料供给阀以进行控制，以减少燃料供应，直到该气缸中不再超过最大温度。对于由另一个传感器确定的任何气缸中的工作气体的较高温度，一般关闭阀减少了常见的燃料供应。辅助空气源提供用于燃料喷射的雾化空气。

摘要： A thermally insulating lining for the housing of the heater system ensures that on the outside of the heater system only low temperatures are reached which are not dangerous to operators in the vicinity of the engine. Combustion air duct means between an air preheater and a burner is formed by a large number of tubes arranged alongside each other in at least one row and along an inside wall of the combustion chamber. These tubes ensure that the flow state remains satisfactory and constant and they are substantially more durable than sheet metal duct means as used hitherto.
