Embodiment
Core of the present utility model is to provide a kind of cylinder body cooling unit of vehicular engine, to being convenient to processing, and can ensure the smooth realization of cylinder casting technique, improves turbidity test and the cooling performance of cylinder body water jacket.Another core of the present utility model is to provide a kind of vehicular engine comprising above-mentioned cylinder body cooling unit.
Please refer to Fig. 2, Fig. 2 is the structural representation of a kind of embodiment of cylinder body cooling unit provided by the utility model.
In a kind of embodiment, cylinder body cooling unit provided by the utility model is used for vehicular engine, and this cylinder body cooling unit comprises the water jacket 21 be cast in each cylinder body, with the connecting tube 22 being communicated with water jacket 21 described in adjacent two; Described water jacket 21 offers cooling liquid via hole, and along coolant flow direction, the liquid feeding end of described connecting tube 22 is connected with the cooling liquid via hole of the water jacket 21 being positioned at front side, and its outlet end is connected with the cooling liquid via hole of the water jacket 21 being positioned at rear side; Like this, be connected by connecting tube 22 between water jacket 21 in adjacent cylinders, compared with prior art, eliminate thin-walled water jacket 21 structure, thus reduce casting difficulty, improve processing convenience, ensure that the smooth realization of cylinder casting technique, and avoid production defect, improve turbidity test and the cooling performance of cylinder body water jacket 21.
