FIELD: mechanical engineering; diesel engines. ^ SUBSTANCE: invention relates to supercharging devices of diesel engines. Proposed diesel engine supercharging system includes compressed air storage reservoirs connected with air distributor through air supply electromagnetic valve, and maximum pressure valve, main distributing pipeline and cylinders of diesel engine. Main distributing pipeline is divided into two parallel distributing pipelines. One of said pipelines is connected with group of odd cylinders of diesel engine through branch pipes and calibrated nozzles, and the other is connected by branch pipes through calibrated nozzles with group of even cylinders of diesel engine. Two branch pipes are connected to each cylinder. One of branch pipes from distributor pipeline is connected to intake valve at angle of 45°. Check valves are installed at inlet of each distributing pipeline. Automatic control system is used to provide accurate and distinct delivery of additional air, depending on operating conditions of diesel engine. ^ EFFECT: increased efficiency of supercharging system. |
