Intake silencer system for air compressor pump and extended-range electric vehicle adopting intake silencer system

Abstract

The invention discloses an intake silencer system for an air compressor pump and an extended-range electric vehicle adopting the intake silencer system. The intake silencer system comprises an air filter, a turbocharger, an intercooler, an engine, the air compressor pump and an air storage tank. The air filter, the turbocharger, the intercooler and the engine are connected in sequence to form a first airflow channel. Air sequentially passes through the air filter, the turbocharger and the intercooler and reaches the engine. The air filter, the turbocharger, the intercooler, the air compressor pump and the air storage tank are connected in sequence to form a second airflow channel. The air sequentially passes through the air filter, the turbocharger, the intercooler and the air compressor pump and reaches the air storage tank. The intake silencer system and the extended-range electric vehicle have the beneficial effects as follows: an excellent silencing effect on the air compressor pump is achieved, the number of system components is reduced, the structure is simple, and the manufacturing cost and the maintaining cost are reduced; waste gas energy of the engine is sufficiently used, the efficiency of the air compressor pump is improved, and the energy consumption of a finished automobile is reduced; and the working intensity of the air compressor pump is reduced, the service life is prolonged, and the maintenance interval is prolonged.

Description

Technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an air-intake muffler system of an air compression pump and a range-extended electric vehicle. Background technique [0002] At this stage, the compressed air source used for brake boosting, clutch boosting, door opening and closing of large vehicles is provided by a vehicle-mounted air compression pump system (referred to as air pump). There are different types of air pressure pumps, such as plunger type, screw type and dicing type. Plunger air compressor technology is mature and widely used in all walks of life. It has a complete supply and guarantee system. Its reliability has been fully verified. Its manufacturing cost is unmatched by other types of air compressors, but its intake airflow is pulsating. , Which makes the intake air flow easy to produce noise, and it must be silenced when used in quiet places. [0003] Such as figure 1 As shown, the air compression pump sy...

Problems solved by technology

[0004] Because electric vehicles have high requirements for driving comfort, conventional plunger air pumps have low intake pulsation noise frequency, and conventional mufflers are bulky and costly, which restricts the application of plunger air pumps on electric vehicles. application

In order to meet the silent needs of electric vehicles, manufacturers have to choose other forms of air pump systems that are expensive and unreliable, which greatly increases the manufacturing cost and maintenance cost, which affects the competitiveness of the whole vehicle
