The New Combustion Engine

/0 Comments/in /by

Consider a combustion engine. The air inlet valve opens, the piston starts to go down, and the suction stage begins. As the volume of the cylinder increases, it is filled with air. After the end of the intake stage, the intake valve is closed, and with the command of the ECU, the piston rises to compress the air. After reaching TDC, ignition is carried out, and the pressure from combustion pushes the piston down. This is the stage of combustion and power generation.

But here, there is a fundamental difference: this stage continues until the pressure inside the cylinder is no longer able to push the piston down, and the maximum power is produced. This is the opposite of conventional Otto or Miller cycle engines.

The piston stops when the ECU issues the command to open the exhaust valve. In this engine, expansion may continue up to three times the length of the piston stroke.

For this reason, combustion in this engine takes place completely, and after opening the outlet valve, all the fuel drops are combusted, and the only output is carbon dioxide.

This invention pertains to the field of fluid dynamics, specifically to hydraulic pumps and motors used in industrial, automotive, and other applications requiring fluid transfer and mechanical power conversion.

**Background**:
Conventional hydraulic pump systems often face limitations such as cavitation, inefficiency, and mechanical wear. Cavitation occurs when the fluid provided to the pump is insufficient, causing the formation and collapse of vapor bubbles, leading to damage. Existing solutions involve pressurizing the pump intake or using auxiliary pumps, but these approaches are not entirely effective in eliminating cavitation and its associated costs.

**Summary of the Invention**:
The primary objective of this invention is to provide a hydraulic pump and motor system with mobile chambers that significantly improves fluid handling efficiency and system adaptability while preventing cavitation. The mobile chamber design allows for dynamic adjustments in chamber volume, optimizing fluid transfer rates and mechanical power output based on real-time operational demands.

**Detailed Description**:

1. **Construction**:

– **Enhanced Efficiency**: The mobile chamber design minimizes energy losses by optimizing fluid flow and pressure throughout the pump and motor operation.
– **Adaptability**: The system’s ability to adjust chamber volume in real-time allows it to adapt to varying operational conditions, making it suitable for a wide range of applications.
– **Compact Design**: Integrating the pump and motor functionalities into a single unit with mobile chambers reduces the overall system size, making it ideal for applications with space constraints.

3. **Control System**:
– The invention includes an advanced control system managed by an Electronic Control Unit (ECU). The ECU monitors operational parameters such as fluid pressure, flow rate, and mechanical load, adjusting the mobile chamber volume accordingly to optimize performance.
