Abstract

The invention relates to the technical field of diesel engine control, in particular to an accelerator actuator and a diesel engine. The accelerator actuator comprises an actuator shell, a first motor, a first driving assembly, a second motor, a second driving assembly and a transmission assembly; the actuator shell is provided with a mounting cavity; the first motor is arranged on the actuator shell; the first driving assembly is arranged in the mounting cavity and is in transmission connection with an output shaft of the first motor; the second motor is arranged on the actuator shell; the second driving assembly is arranged in the mounting cavity and is in transmission connection with an output shaft of the second motor; the transmission assembly is arranged in the mounting cavity, can be in selective transmission connection with the first driving assembly or the second driving assembly, is in transmission connection with an oil supply device and is used for controlling the supply amount of fuel oil. According to the accelerator actuator, when the first motor breaks down, a power source can be rapidly switched to the second motor for driving in the mode that the first driving assembly and the second driving assembly are electrically controlled.

Description

technical field [0001] The invention relates to the technical field of diesel engine control, in particular to an accelerator actuator and a diesel engine. Background technique [0002] The throttle actuator can control the speed of the diesel engine by controlling the oil supply of the diesel engine. With the rapid development of electronic technology, the throttle actuator can be controlled electrically. The electronic throttle actuator used in the prior art only has one motor. Once the motor breaks down, the fuel supply cannot be controlled, which will cause the diesel engine to fail to operate normally, and even cause accidents. Contents of the invention [0003] The purpose of the present invention is to provide an accelerator actuator to solve the problem that the electronic accelerator actuator used in the prior art has only one motor, and once the motor fails, the oil supply cannot be controlled, resulting in the diesel engine not running normally. [0004] For re...
