Problems solved by technology

At present, the cylinder pressure sensor installed on the spark plug is generally used to collect the combustion pressure data. Since the ignition of the spark plug and the pressure collection affect each other, the accuracy of the cylinder pressure data measured by this method is limited and has certain limitations.
[0003] Now it is more inclined to use the method of drilling and installing a cylinder pressure sensor on the cylinde...

Embodiment Construction

[0018] Such as Figure 1 to Figure 4 As shown, the engine cylinder head used for combustion development includes a cylinder head 1 and a cylinder cover 6 fixed on the top thereof, and a spark plug hole, a sand outlet process hole, an oil return chamber 8 and a cooling water channel 10 are opened on the cylinder head 1, A combustion chamber 12 is opened at the bottom of the cylinder head 1 .

[0019] A first installation hole 2 and a second installation hole 11 are opened on the cylinder head 1. The first installation hole 2 is located between the spark plug hole and the sand production hole, and connects the oil return chamber 8 with the cooling water channel 10. The axis line Near the center of the combustion chamber 12; the second installation hole 11 is a stepped hole, which communicates the cooling water channel 10 with the combustion chamber 12, and the first installation hole 2 and the second installation hole 11 are coaxial. An outer copper sheath 9 is installed in the...

Abstract

The invention relates to an engine cylinder cover for combustion development at the combustion development experiment stage of an automobile engine. The engine cylinder cover comprises a cylinder cover and a cylinder hood fixed on the top of the cylinder cover, wherein the cylinder cover is provided with first and second mounting holes for communicating a return oil cavity and a cooling water passage and communicating the cooling water passage and a combustion chamber; and copper sleeves are arranged in the mounting holes. Cylinder pressure sensors are arranged at the lower ends of the copper sleeves so that the cylinder pressure sensors are arranged in the combustion chamber of the cylinder cover; and the cylinder cover does not leak air, water and oil.

Description

technical field [0001] The invention relates to parts of automobile engines, especially cylinder heads of automobile engines. Background technique [0002] During the development and development of automobile engines, it is necessary to collect combustion pressure data in the combustion chamber of the cylinder head during the combustion development experiment stage. At present, the cylinder pressure sensor installed on the spark plug is generally used to collect the combustion pressure data. Since the ignition of the spark plug and the pressure collection affect each other, the accuracy of the cylinder pressure data measured by this method is limited and has certain limitations. [0003] Now it is more inclined to use the method of drilling and installing a cylinder pressure sensor on the cylinder head to collect the combustion pressure data in the combustion chamber. , there is high-temperature and high-pressure gas in the combustion chamber, high-temperature water in the ...
