The invention relates to a non-sticky ventilation and heat-dissipation front grille for an engine. The non-sticky ventilation and heat-dissipation front grille for the engine comprises an outer grille frame (1) and an inner grille frame (2). Two grille assemblies are arranged in the outer grille frame (1). Two insert pieces (5) are arranged at the rear end of the outer grille frame (1). Outer fixing pieces (6) are arranged at the left end and the right end of the bottom of the outer grille frame (1) correspondingly and extend towards the outer side of the outer grille frame (1). Non-sticky layers are arranged on the surface of the outer grille frame (1) and the surfaces of transverse connecting rods (3) correspondingly. The non-sticky ventilation and heat-dissipation front grille for the engine can be well fixed and is firmer in connection; a vehicle logo can be well fixed and is firmer; the front grille can be connected with a vehicle body extremely firmly and is not prone to falling; and dust is unlikely to be accumulated on the surface of the front grille, and thus the front grille is convenient to clean.
