Our company's ESD5500E adopts digital control technology with good quality. On the basis of the company's digital ESD5111, the startup fuel volume control and smooth and slow startup process control are newly added, and the setting of parameters can be automatically identified and adjusted. These new features can solve the black smoke phenomenon caused by rapid refueling during the startup process of the engine, and greatly improve the engine life. It is currently a model with very rich and complete functions, and is widely used in the new generation.
