Abstract

The invention provides a throttle control mechanism suitable for cold starting of a diesel engine. The throttle control mechanism comprises an auxiliary pull rod (5), a sleeve (6), an electromagneticswitch control rod (7) and an electromagnetic switch (12). One end of the electromagnetic switch control rod (7) extends into the electromagnetic switch (12), and the electromagnetic switch (12) controls the extending amount of the electromagnetic switch control rod (7). The other end of the electromagnetic switch control rod (7) is in rigid connection with the sleeve (6). A matching end of the auxiliary pull rod (5) is mounted in the sleeve (6) in an inserted mode. A shaft extension end of the auxiliary pull rod (5) is connected with a throttle pulling mechanism. The mechanism solves the problems that friction force of the throttle control mechanism of the diesel engine is increased due to the fact that fit clearances of the throttle control mechanism of the diesel engine are decreased under a low temperature condition, and the viscidity of engine oil and diesel is increased, and can rapidly increase the speed of the diesel engine to a rated rotation speed under the low temperature condition, and thus it can be ensured that the diesel engine can be engaged in work rapidly at the rated rotation speed.

Description

technical field [0001] The invention relates to the field of diesel engines, in particular to an accelerator control mechanism suitable for low-temperature starting of diesel engines. Background technique [0002] Under low temperature conditions, the matching clearance of the throttle control mechanism of the diesel engine decreases, and the friction force increases. At the same time, due to the increase in the viscosity of the oil and diesel, the friction force of the throttle control mechanism of the diesel engine increases. If there is a diesel engine, heating the intake air of the diesel engine and replacing the low-temperature engine oil and diesel that meet the ambient temperature still cannot solve the problem of slow acceleration. [0003] Existing throttle control principle: the actuator issues instructions to control the actuator control lever, and the movement of the rack is controlled in real time through the control lever to finally control the opening and clos...
