Cylinder head and engine with same

Abstract

The invention provides a cylinder cover and an engine. A cooling water jacket is arranged in the cylinder cover, and comprises an upper layer water jacket body, a middle layer water jacket body and alower layer water jacket body which are sequentially arranged from top to bottom; the side wall of the cylinder cover is provides with different water inflow holes communicating with the upper layer water jacket body, the middle layer water jacket body and the lower layer water jacket body; and cooling liquid can enter the upper layer water jacket body, the middle layer water jacket body and the lower layer water jacket body through the different water inflow holes to cool different areas of the cylinder cover. According to the cylinder cover and the engine, by arranging a thick fire power plate to meet the high detonation pressure and high load requirement of the cylinder cover, the strength level of the cylinder cover is substantially improved; due to the fact that the side face of the fire power plate is provided with cooling through holes, the three-layer cooling water jacket structure is formed; the bottom plate can be cooled through the middle layer water jacket body and the lower layer water jacket body at the same time, and the cooling capacity of the cylinder cover is enhanced; and the side face of the cylinder cover is provided with an installing hole for installing a detonation pressure sensor, through the detonation pressure sensor, detonation pressure of the engine can be monitored in real time, and a huge fault is prevented from happening.

Description

technical field [0001] The invention relates to the technical field of engine cylinders, in particular to a cylinder head and an engine with the same. Background technique [0002] The cylinder head is an important part of the engine, and its function is to seal the gas and form the combustion space together with the piston. The working environment is extremely harsh, and due to the action of high temperature and high pressure gas, the thermal stress and mechanical stress are very large. The highest temperature of the cylinder head occurs in the center of the fire plate of the cylinder head, that is, the "nose bridge area". [0003] Existing cylinder heads generally use vermicular iron materials, optimize the structure of the cooling water jacket, and strengthen the local structure of the cylinder head to meet the high explosion pressure and high load requirements of various models. However, when the cylinder head is in use, the temperature of the cooled cylinder head is s...

AI Technical Summary

Problems solved by technology

However, when the cylinder head is in use, the temperature of the cooled cylinder head is still too high, and the thermal load of the cylinder head is too large, which is prone to thermal fatigue or even cracks, resulting in failure of the cylinder head and engine failure

In addition, the existing cylinder head does not monitor the explosion pressure in real time. When the engine burns abnormally, it cannot be known immediately, which may cause major failures and cause heavy losses.
