Abstract

The invention discloses an engine water pump and an engine, relates to the field of engine technologies, and aims at meeting the requirements of the engine on the flow of the water pump under different work conditions. The engine water pump comprises a water pump shaft, wherein a plurality of blades are arranged on the water pump shaft along the circumference, the blades are hinged to the water pump shaft, the blades are connected with a blade angle regulating mechanism, and the blade angle regulating mechanism is used for driving the blades to rotate relative to the water pump shaft. The engine water pump is mainly used for cooling the engine.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine water pump and an engine. Background technique [0002] At present, how to save energy and reduce emissions has become an urgent problem in the automotive engine industry. In order to improve the fuel economy of the engine, many energy-saving and emission-reducing technologies have been applied to the engine. Among them, the thermal management of the engine is a recognized means to improve fuel economy, and the important content of thermal management is to provide the best water pump flow according to the different working conditions of the engine, so as to achieve the best cooling effect on the engine. Keep the engine operating temperature normal. [0003] For example, under the condition of low speed and heavy load of the engine, in order to suppress deflagration, it is necessary to increase the flow rate of the water pump and improve the cooling capacity; Reduce th...
