A1
Abstract:
An operating device for cold start of diesel engines in highland and alpine regions and a control method thereof employ a starter to drive a plunger to compress low-temperature air, and then the air having an elevated temperature is introduced into a cylinder as fresh intake air, such that a temperature inside the cylinder rises to an ignition temperature at top-dead-center of compression stroke, thereby realizing smooth cold start of a diesel engine in an alpine region. The operating device and control method do not require a complicated preheating device. The invention has a simple structure and reliable performance, and can realize effective cold start of diesel engines in different low-temperature environments.
