PRE-COMBUSTION ADJUSTMENT

Description

/ 6 PRE-COMBUSTION ADJUSTMENT Field of invention

[001] PCA technology – Pre-Combustion Adjustment – ​​represents a completely unprecedented innovation in the global market, introducing a level of control and optimization in engine combustion that has not been achieved until now. While electronic control systems are widely used for monitoring and telemetry, they operate in isolation and do not directly intervene in the engine's injection strategies. PCA goes further, integrating an intelligent additive system that dynamically adjusts combustion parameters based on real-time data captured by the vehicle's sensors. This ability to automatically and precisely intervene in combustion, coordinated with the engine's electronic controls, is unprecedented in the automotive market.

[002] The absence of similar systems on the market reinforces the innovative nature of PCA. The technology not only monitors engine performance but also acts directly on it, optimizing the air-fuel mixture and ignition timing in response to operational variables such as load, temperature, and fuel type. This intelligent pre-combustion additive, dependent on electronic controls, allows the engine to operate at maximum efficiency, regardless of external conditions or fuel quality, something that no other system currently offers.

[003] PCA definitely fills a technological gap in the automotive sector, offering an integrated solution that covers everything from monitoring to active intervention in combustion. The unique combination of electronic control and intelligent additives makes PCA a disruptive technology that not only improves efficiency and reduces emissions, but also redefines the standards of innovation for combustion management systems in automotive engines. This technological scope, coupled with the ability to adapt and optimize in real time, confirms PCA's unprecedented status on the global stage.

[004] The proposed project is fully aligned with transport decarbonization technologies focused on urban mobility, developing equipment with components, assemblies and systems that contribute to the reduction of carbon emissions in land transport (circulating on streets, roads, highways and railways) and water transport (river and sea), in urban and rural environments.

[005] In summary, our proposal deals with the development of an embedded technology for vehicles, called PCA - Pre-Combustion Adjustment, which optimizes the consumption of liquid fuels, aiming to increase energy efficiency and reduce emissions of polluting gases. With this technology, we aim to reduce the consumption of fossil fuels in motor vehicles and consequently improve their efficiency, reducing emissions of carbon, toxic gases and particulate matter. Fundamentals of the invention

[006] In the search for more sustainable and efficient fuel sources using liquid fuels, we believe that the development and application of new technologies such as embedded intelligence in transportation systems are fundamental, contributing to greater vehicle autonomy and reductions in particulate matter, polluting gases, and greenhouse gases. Pollution and gas emissions from combustion in motor vehicles are largely responsible for the deterioration of air quality, respiratory diseases, and global warming, representing a critical problem for both Brazil and the world. In Brazil, the transportation sector is one of the largest emitters of CO, nitrogen oxides (NO), and particulate matter, exacerbating public health problems and contributing significantly to climate change.Globally, rising vehicle emissions pose a constant threat to meeting the greenhouse gas reduction targets set out in the Paris Agreement, making it essential to adopt technologies that promote an urgent transition to cleaner and more sustainable transport practices.

[007] Our development proposal is to create an easily installed embedded technology that can be approved by manufacturers and incorporated into projects at assembly plants for new and existing fleets. This technology improves operational efficiency and contributes to the transition to cleaner and more renewable energy sources. This technology is called PCA - Pre-Combustion Adjustment. Our PCA proposal aims to automatically assist the largest mode of transportation in Brazil, improving its energy efficiency, increasing its range, and significantly reducing its environmental impact.

[008] Optimizing fuel combustion is a crucial element for improving energy efficiency and reducing carbon emissions. The PCA control unit will play a key role in this process, using advanced algorithms to analyze performance, consumption patterns, and environmental emissions. The PCA can predict fuel consumption patterns based on specific conditions such as traffic, terrain, vehicle and driver characteristics. These predictions are then used to dynamically adjust the injection and treatment module to optimize the fuel used for each situation. These real-time interactions will provide differentiated combustion efficiency, reducing specific fuel consumption, emissions, and maintenance related to the injection and exhaust gas treatment system. Brief description of the drawings

[009] Regarding the illustrations and drawings, we have: • Figure 1 illustrates the main components of the PCA system. Figure 2 illustrates the flow between the sensors and actuators of the PCA system. Description of the invention

[0010] The PCA has an ECU control unit that is connected to the CAN bus. Through this connection, it interacts with some of the system's actuators, optimizing the driver's actions, such as the appropriate acceleration modulation. The PCA checks the acceleration requested on the accelerator pedal and corrects the information. Petition 870250058444, dated 09 / 07 / 2025, page 6 / 10 / 6 for the throttle body according to load conditions, speed, temperature, intake air pressure, etc.

[0011] Simultaneously, the PCA uses the lambda sensor to check combustion efficiency and interacts with the system to optimize energy use, adjusting injection time, injected volume, and injected fuel temperature. If it is not possible to adjust the parameters at a given moment using only the available fuel, the PCA's compartmentalized bulk reservoir comes into action.

[0012] The Bulk system contains liquid additives responsible for improving the quality of the mixture at critical moments, ensuring good performance and proper combustion, improving performance and reducing emissions. The Bulk system has a set of actuator valves that doses the appropriate additives using information such as intake pressure, engine temperature, lambda sensor readings, among others. This ensures that the mixture has the most suitable characteristics for each type of application.

[0013] The Bulk system doesn't activate constantly; it assists in achieving optimal combustion. In addition to the sensors mentioned, we can also have a chemical sensor in the fuel tank that provides an advance reading of fuel quality, informing the PCA system's ECU beforehand so that necessary corrections can be made.

[0014] An interactive panel displays information to the driver, allowing for adjustments to driving modes such as economy mode, energy efficiency mode, or power mode, all aimed at optimal combustion efficiency and reduced emissions. This same interactive panel informs the driver of the fuel level in the bulk system and when to replace it (on an exchange basis) in a simple way through quick-connect fittings and couplings. The bulk system can be purchased for each type of engine (Otto or Diesel), and the PCA ECU recognizes the bulk system and the engine, making the necessary adjustments.

[0015] PCA - Pre-Combustion Adjustment technology offers a number of technological advantages over traditional systems currently used in motor vehicles. One of the main differences is the PCA's ability to dynamically adjust combustion parameters, such as air-fuel mixture and ignition timing, based on real-time data from sensors installed in the vehicle. While conventional systems operate with fixed parameters or limited adjustments, PCA uses an advanced control system (ECU) that connects to the vehicle's CAN bus, allowing continuous adaptation to operating conditions such as load, temperature, and speed. This results in more efficient combustion, lower fuel consumption, and a significant reduction in pollutant emissions.

[0016] The PCA, with a high-capacity processor, can process data quickly and accurately, working in conjunction with engine sensors and actuators and a reservoir of elements and additives, optimizing the air-fuel mixture and ignition timing to improve combustion efficiency. Furthermore, the PCA has the ability to precisely adjust engine parameters and inject special additives at the appropriate times, resulting in increased power and torque, improving overall vehicle performance.

[0017] The PCA can constantly adjust fuel injection, including adding elements and additives, to ensure the engine is operating at maximum efficiency, resulting in lower fuel consumption and smoother, more efficient engine performance. Through dynamic adjustments, the PCA allows the implementation of various driving modes (economic, sport, etc.) that adjust power delivery and fuel consumption as needed. By constantly managing combustion parameters more effectively, we also automatically reduce pollutant emissions: • Lower CO2 Emissions: It reduces consumption and, as a consequence, its use can significantly reduce CO2 emissions, contributing to the mitigation of climate change. Petition 870250058444, dated 09 / 07 / 2025, page 8 / 10 / 6 • Fewer Particles and NO: Improves combustion and produces fewer particles (particulate matter) and nitrogen oxides (NO), improving air quality. • Lower Carbon Monoxide (CO) Emissions: Improves combustion efficiency, which also leads to a reduction in carbon monoxide emissions. • Lower Emissions of Unburned Hydrocarbons: With more complete combustion, the amount of unburned hydrocarbons released by the engine also decreases, contributing to less air pollution.

[0018] Its continuous monitoring also allows for the rapid detection and correction of any problems that may cause excessive emissions and reduces the formation of deposits in the fuel system and intake valves. Furthermore, it performs customized adjustments to engine and transmission parameters to adapt vehicle performance to individual preferences or specific driving conditions. It ensures the use of the most suitable engine maps, optimizing performance for different scenarios.

[0019] The technology is completely “Drop In,” meaning it can be used in existing engines without significant modifications, compatible with Diesel and Gasoline / Flex engines, without requiring engine alterations. PCA also employs elements and additives miscible in any proportion with commercial fuels, facilitating their addition to the fuel without the need for significant changes. These additives use elements produced from renewable sources, contributing to the circular economy. In parallel, it promotes the idea of ​​reducing dependence on fossil fuels, thus promoting the development of the energy transition to renewable fuels.

[0020] In summary, PCA offers significant improvements in terms of performance, efficiency, emissions reduction, safety and connectivity. It allows for more precise control of engine parameters, improving the driving experience and extending the vehicle's lifespan. Petition 870250058444, dated 09 / 07 / 2025, p. 9 / 10
