Abstract

The invention provides a high power motor actuator for diesel engine speed regulation. The high power motor actuator comprises a main shell, a direct-current motor and an eddy current sensor. Two ends of the main shell are respectively provided with a front end cover and a rear end cover. The direct-current motor is fixed in the main shell and is connected to an output shaft through a harmonic reducer, and output shaft penetrates from the front end cover and is connected to a fuel injection pump rack of a diesel engine, the eddy current sensor is arranged in the main shell and is fixed to the front end cover through a sensor support, the output shaft is provided with an eccentric wheel, the direct-current motor controls the output shaft to drive the fuel injection pump rack of the diesel engine to move, and the eddy current sensor is used for detecting the position of the eccentric wheel to detect the rotary angle of the output shaft. The harmonic reducer is used for deceleration, the rotary angle of the output shaft is regulated, accurate regulation of the rack can be implemented, and a diesel engine position controlled electronic speed regulating function can be realized well.

Description

technical field [0001] The invention relates to a diesel engine, in particular to a fuel injection control device for a diesel engine. Background technique [0002] At present, there is a worldwide energy shortage and serious environmental protection issues. Requirements such as low energy consumption, low emissions, high power density, and compact structure have been put forward for diesel engines, which has promoted the development of diesel engine speed regulation technology. One of the indicators of advanced performance. [0003] Most marine diesel engines in my country use mechanical and position-controlled electronic speed-regulating actuators. Position-controlled electronic speed-regulating actuators generally use proportional electromagnets, torque motors or electro-hydraulic actuators as the moving parts of the actuators, which are used for small, Medium and high power diesel engine speed control. As an electronic speed control actuator, the proportional electromag...
