Abstract

The invention relates to a dynamic air supplying device of a turbocharged diesel engine. The device comprises a main turbocharger connected with a waste gas exhaust pipe of the engine. An auxiliary turbocharger connected with the main turbocharger in series is also arranged on the waste gas exhaust pipe of the engine. The auxiliary turbocharger comprises an auxiliary turbine and an auxiliary booster, which are connected coaxially. An air outlet pipe of the auxiliary booster is connected with an air inlet manifold of the engine through an air storage tank. An electric by-pass valve is installed on the auxiliary turbine in parallel. An electric air supplying valve is arranged between the air storage tank and the air inlet manifold of the engine. By adopting the dynamic air supplying device disclosed by the invention, air can be supplied in time before the air-fuel ratio of the engine is out of balance; after the engine enters a normal working state, the dynamic air supplying device exits timely; power and electric resources of vehicles are not used; and adverse effects on the vehicles cannot be resulted.

Description

technical field [0001] The invention relates to an engine intake air supply device, in particular to a dynamic air supply device for a turbocharged diesel engine. Background technique [0002] In order to solve the problems of convenient travel for urban residents and urban road congestion, large and medium-sized cities generally give priority to the development of urban public transport systems. With the development of urban public transport system, the tail gas pollution and energy consumption of public transport vehicles have attracted more and more attention from the society, which is also related to the image of the city. In addition to subways and rail transit, cities generally try to adopt low-emission and zero-pollution vehicles such as vehicles using natural gas and electric vehicles. Nevertheless, the power system of urban public transport vehicles is still dominated by diesel engines, and it is very common for public transport vehicles to start and accelerate to ...
