Abstract

The invention discloses an air cylinder head and an engine, relating to the technical field of engines. The air cylinder head comprises a cylinder head matrix and a support seat which are integrally formed, wherein the support seat is located in the cylinder head matrix and forms a mold cavity with the cylinder head matrix; the cylinder head matrix comprises a first mounting surface and a second mounting surface, the first mounting surface is located at the top of the cylinder head matrix and is fixedly connected with an air cylinder cover, the second mounting surface is located at the bottomof the cylinder head matrix and is fixedly connected with an air cylinder body, and the first mounting surface is obliquely arranged relative to the second mounting surface to enable the cylinder headmatrix to form relatively high and low sides; and a perforated chain cavity is formed in the high side and is located between the cylinder head matrix and the support seat, and a sparking plug mounting hole is formed in the lower side, is located on one side, close to the second mounting surface, of the cylinder head matrix and is obliquely formed relative to the second mounting surface. The aircylinder head is reasonable in design and convenient to produce, manufacture and assemble, the production difficulty is greatly reduced, the production and assembling processes are simplified, and theproduction cost is lowered.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a cylinder head and an engine. Background technique [0002] Water cooling is to use water (or antifreeze) as a cooling medium to take away the heat from high-temperature parts of the engine to ensure the normal operating temperature of the engine. The water cooling system consists of water pumps, radiators, fans, thermostats, water jackets and water pipes. The coolant of the water-cooling system is in the water jacket of the engine. After absorbing the heat of the high-temperature parts, the temperature rises. The radiator is cooled by the fan and the windward airflow, and then the cooled coolant is pumped into the water jacket for circulating cooling. [0003] Under the premise of satisfying the processing of the rocker shaft hole, the mounting hole of the camshaft limit plate and the installation of the water pump assembly in the existing engine, it is difficult to machine th...
