Solution Overview
Problem
Existing receiving components for pre-chamber components in internal combustion engines face challenges in efficiently dissipating heat while being economically viable, as materials with high thermal conductivity like copper are expensive and those with lower conductivity like steel alloys are not sufficient.
Innovation Solution
A receiving component composed of two different materials, with a high thermal conductivity area made of copper alloy and a lower thermal conductivity area made of steel alloy, joined together to form a single component, addressing thermal dissipation needs while being resource-efficient.

Engineering Contradiction Analysis
1Temperature
If copper alloy is used for the receiving component to improve thermal conductivity, then heat dissipation capability is improved, but material cost increases significantly
Solution Approach 1:
The receiving component is designed with a composite structure where the first area (in contact with pre-chamber and ignition medium) is made of copper alloy for high thermal conductivity, while the second area (exposed to lower thermal influences) is made of steel alloy. This local differentiation allows optimal thermal management where needed while reducing overall material cost.
Solution Approach 2:
The invention uses a composite material structure combining copper alloy and steel alloy in a single receiving component. The copper alloy provides superior thermal conductivity in the critical first area, while the steel alloy provides structural integrity and cost-effectiveness in the second area, achieving both thermal performance and economic viability.
