AI Technical Summary
Technical Problem
Existing internal combustion engines face challenges in increasing the methanol ratio in fuel mixtures to reduce greenhouse gases without requiring special injectors or causing combustion failures due to methanol's low lubricity and biodiesel's condensation issues.
Method used
An internal combustion engine design with separate injectors for methanol injection into the intake port and biodiesel injection into the combustion chamber, using existing injectors and a heating unit to prevent condensation, allowing for a higher methanol proportion and avoiding combustion failures.
Benefits of technology
Enables increased methanol use to reduce greenhouse gases while preventing injector wear and combustion issues, using existing injectors and minimizing biodiesel condensation.

Abstract
This technology allows for a reduction in greenhouse gas emissions by increasing the methanol ratio without requiring a special injector, while also preventing combustion failures. [Solution] The engine 1 comprises a cylinder liner 2, a cylinder head 3, a piston 4, a combustion chamber 9 formed by these, an intake port 5 communicating with the combustion chamber 9, a first injector 12 that injects methanol into the intake port 5, and a second injector 23 that injects ignition fuel containing biodiesel fuel into the combustion chamber 9.
