His innovative work focuses on improving fuel injection systems, which are crucial for enhancing engine efficiency and performance.

Latest Patents

Among his latest patents, Manuel has developed a modular fuel injection pump for internal combustion engines. This invention relates to an injection pump designed to selectively cut off fuel delivery to a variable number of cylinders in a multi-cylinder engine. This feature allows for optimal fuel consumption when the engine operates below its maximum power output. Another notable patent is for the control of pistons in injection pumps of internal combustion engines. This invention proposes a design where the rotary motion of the distributor piston operates at a slower speed than the cam members controlling the axial piston stroke. This improvement enhances the working conditions of the cam members and increases the pumping speed of the piston.
