Description

Engine controller

Technical field

The utility model relates to a kind of power equipment, particularly a kind of engine controller.

Background technique

In order to meet the upgrading needs for diesel engine state IV emission standard, at present more concernedly in the Heavy Duty Diesel Engine discharging mainly contain two kinds of technology paths, be DPF particle trap and SCR selective reduction technology, but, due to the restraining factors such as workload is large, the cycle is long and expense is high, can't be widely used.Simultaneously because cell voltage can't be guaranteed, thereby make the heating of low limit driver become large, likely cause impaired situation, therefore, just need to an energy be controlled it by the engine controller that working efficiency performs to the optimum state.

The model utility content

The purpose of this utility model just is to provide a kind of engine controller, can address the above problem fully.

to achieve these goals, the technical solution adopted in the utility model is such: engine controller of the present utility model, comprise clock control device, input-output unit, analogue signal processor, the pulse signal processor, the engine parameter device, communication device, low limit driver, high side drivers, the booster circuit driver, igniting injector controller and controllor for step-by-step motor, clock control device is electrically connected with input-output unit and controllor for step-by-step motor respectively, input-output unit and analogue signal processor are electrically connected, analogue signal processor and pulse signal processor are electrically connected, pulse signal processor and engine parameter device are electrically connected, engine parameter device and communication device are electrically connected, communication device and low limit driver are electrically connected, low limit driver and high side drivers are electrically connected, high side drivers and booster circuit driver are electrically connected, the booster circuit driver is electrically connected with the igniting injector controller, igniting injector controller and controllor for step-by-step motor are electrically connected.

As preferably, described controllor for step-by-step motor comprises stepper motor driver module and low side driver module.

As preferably, described clock control device comprises the DS1302 clock chip.

Compared with prior art; the utility model has the advantage of: this engine controller can spray fuel oil, igniting and air inlet etc. are controlled; thereby make motor be in optimum Working; simultaneously in the situation that likely produce driving malfunction, can in time by stopping driving, protect driver.
