Automatic high-power diesel engine piston top dead center tracing system

The invention relates to the field of diesel engines, in particular to an automatic high-power diesel engine piston top dead center tracing system. The automatic high-power diesel engine piston top dead center tracing system includes starting steps and a control flow. The starting steps are as follows: (1) a servomotor outputs power; (2) a torque booster outputs power; and (3) a turning mechanism turns a crankshaft to rotate. The control flow is as follows: (1) a linear displacement sensor acquires variable data; (2) the variable data are fed back to a programmer; (3) an instruction is sent to a servocontroller; (4) the servomotor is controlled; (5) power is transmitted to the torque booster; (6) the turning mechanism is driven; and (7) the turning mechanism turns the crankshaft. The automatic high-power diesel engine piston top dead center tracing system adopts the integration of the sensing technology and electromechanical control, thus achieving high precision and high accuracy, the automatic high-power di
