Diesel oil engine starting protection control system and method thereof

Abstract

The invention discloses a diesel oil engine starting protection control system and method thereof; the system comprises an ignition switch (1), a starting relay (2), a starting motor (3), an engine speed sensor (4), an engine water temperature sensor (5), a controller (6), a preheating plug (7), a preheating relay (8), a pilot cut-out solenoid valve (9), a safety rod (10), an instrument (11) and a storage battery; the starting relay is respectively connected with the ignition switch and the controller. The method comprises that the controller collects an ignition switch starting signal, an engine water temperature signal, an engine speed signal and a safety rod state signal, thus realizing engine starting protection control. The system and method can protect the storage battery and the stating motor, thus preventing starting motor and storage battery damages caused by engine low temperature direction starting, long time starting and continuous starting, and further prolonging life of the engine and battery.

Description

technical field [0001] The invention relates to an engine start protection system and method, in particular to a diesel engine start protection control system and a method thereof, belonging to the technical field of engine start protection. Background technique [0002] As a commonly used construction machine, excavators have been widely used in earthwork construction, urban construction, farmland water conservancy construction and other occasions. Combined with the working environment and purpose of the excavator, the existing excavators basically use diesel engines as their power components. At present, most of the methods for starting diesel engines are relatively simple, and there are many operations by customers. It is difficult to strictly follow the operating procedures, such as long-term starting, continuous starting or short starting intervals, direct starting at low temperature, etc., which will seriously affect the battery and starter motor. The use, or even dam...
