The utility model relates to a centralized air inlet device of an engine for road sweepers. An air collection box (3) is arranged on a driving cab. The top of the air collection box is communicated with an air outlet of a prefilter (1) through a connection pipe (2). One side of the air collection box is provided with two air delivery pipes (4) which are respectively communicated with a main engine and an auxiliary engine. When the utility model is used, the air enters the air collection box through the prefilter, enters an air filter of the engine and finally enters the engine. The air is twice filtered, which effectively guarantees the quality of the air entering the engine. As the prefilter self is free from maintenance, the ash cleaning operation is not needed. Thus, the interval time of the cleaning on the filter core of the air filter of the engine can be extended, the service life of the filter core is also extended and the labor intensity and the health damage of ash cleaning workers are reduced. Simultaneously, the utility model has good protection function on engines and extends the overhauling period of the engines.
