Fuel System UNDERSTANDING HOW FUEL POWERS YOUR CAR  Group 3 Joseph Biscaro Johnart Masigan Charles Baluarte Lourence Aquino Bryll Raquel Clarence Rodriguez Tyron Baraquiel  Introduction to the Fuel Ssytem The fuel system is at the heart of any internal combustion engine. It ensures that the engine gets the right amount of fuel to run smoothly. It consists of essential parts like the fuel tank, fuel pump, fuel filter, and fuel injectors or carburetors. These parts work together to store the fuel, filter out impurities, and deliver the right amount for the engine to burn efficiently. A well-functioning fuel system is key to ensuring your vehicle performs well, uses fuel efficiently, and keeps emissions in check. All of which are important for both drivers and the environment.  KEY COMPONENT OF A CAR FUEL SYSTEM 1. FUEL TANK 2. FUEL PUMP 3. FUEL L INES 4. FUEL FI LTER 5.FUEL INJECTORS/CAR BURETOR Fuel Tank - Fuel tank is described as a part of fuel system holding vessel that is in contact with the fuel and allows the fuel to reach the engine with the help of fuel pump. A fuel tank is also called a petrol tank or gas tank is a safe container for flammable fluids, often gasoline or diesel fuel. Fuel Tank A. Purpose and Function Storage: Holds fuel for the engine. Delivery: Sends the fuel to the engine when needed. Ventilation: Manages vapor pressure and airflow. B. Materials Plastic: Lightweight, corrosion- resistant, and flexible. This is also the most common material that is used in petrol tank. Metal: Strong and durable but prone Baffles are the internal panels that help to rust; often coated to prevent prevent fuel from sloshing inside the tank corrosion. during movement.  Fuel Pump A high pressure pumping assembly used in vehicles to deliver fuel to the engine for combustion. * It is used to pump the fuel from the fuel tank. via the fuel lines to the fuel injectors. Types of Fuel Pump 1. MECHANICAL FUEL PUMP Typically used in older vehicles with carburetors. Operates through a diaphragm, creating a suction to draw fuel from the tank. 2. ELECTRONIC FUEL PUMP Common in modern vehicles with fuel injection systems. Located inside or near the fuel tank and uses electrical power to pump fuel at high pressure. Function of Fuel Pump 1. FUEL DELIVERY The fuel pump ensures that fuel is transported from the fuel tank to the engine. 2. PRESSURE MAINTENANCE Ensures that fuel is delivered at the right pressure, which is essential for proper fuel atomization in the combustion process. 3. CONSISTENT FUEL FLOW Maintains a steady Flow of fuel to the engine, regardless of speed or demand. 4. ENGINE PERFORMANCE SUPPORT By regulating fuel pressure, the pump ensures smooth engine operation and optimal performance.  Fuel Lines Fuel lines are components in vehicles and machinery that transport fuel from the fuel tank to the engine. They are a crucial part of the fuel delivery system, ensuring that fuel flows smoothly and safely to power the engine. Fuel lines are typically made from materials like rubber, plastic, or metal (such as steel or aluminum) to withstand high pressures, temperatures, and exposure to fuel and other chemicals. Key functions and features of fuel lines: 1. Fuel Transfer: Fuel lines move gasoline, diesel, or other fuel types from the fuel tank to the fuel pump, fuel injectors, and carburetor (in older systems). 2. Durability: Fuel lines must be resistant to corrosion, wear, and the chemical properties of the fuel they carry. For high-performance applications, braided steel or reinforced rubber lines are often used. 3. Pressure Resistance: They need to handle the pressure exerted by fuel pumps, especially in fuel-injected systems, where the pressure is much higher than in carbureted systems. 4. Safety: Properly designed and maintained fuel lines prevent fuel leaks, which could lead to fires or engine failure. Many modern fuel lines have built-in protective layers to minimize leakage risks. Types of Fuel System Rigid fuel lines: Typically made from steel or aluminum, they are durable and often used in areas where movement or flexibility isn't necessary. Flexible fuel lines: These are made from rubber or synthetic materials and are often reinforced. They're used in areas where the fuel line needs to flex or absorb engine vibrations. Common Issues Fuel line leaks: These can occur due to wear, corrosion, or accidental damage. Clogged lines: Dirt or rust in the fuel system can cause blockages. Cracking or aging: Rubber fuel lines can crack and degrade over time, leading to fuel leakage or reduced performance. Regular maintenance of fuel lines is essential to ensure they remain in good working condition, particularly in older vehicles or machinery. Fuel Filter Acts as a permeable barrier that cleans fuels (it can be diesel or gasoline) impurities, sediments, contaminants, and rust before they can enter the fulel injection system or carburetor. The key to a properly functioning fuel delivery system. The fuel filters must maintenance properly.  Gasoline Carburetor Overview Introduces fuel into the airstream as it flows into the engine. Maintains gasoline in the float chamber by a valve slightly below the jet outlet Air flows downward through the throat, past the throttle valve, and into the intake manifold. A throat formed by reduced diameter reduces pressure, allowing fuel flow from the jet into the airstream. Increased airflow due to changes in engine speed or throttle position increases pressure differential, causing more fuel to flow. Volume ratio of fuel to air maintains with increased flow, but weight ratio increases due to air expansion. Carburetor design includes enriching device, choke, idling system, and accelerating device. Modern Automobile Engines and Fuel-Injection Systems Modern engines use an electronic fuel-injection system in the intake manifold, not a carburetor. The system is a closed-loop feedback system controlled by an engine management system. The system includes sensors, an electric fuel pump, fuel injectors, fuel tubing, and valving. Sensors monitor engine operation and environmental conditions, determining fuel pumping. Advantages of gasoline injection include improved fuel economy, greater power, and uniform fuel load delivery. Electronic fuel injection is commonly used with turbocharged engines as it doesn't rely on an intake manifold vacuum.  Conclusion The car fuel system is essential for powering the engine, with each component playing a crucial role. The fuel tank stores the fuel, while the fuel pump moves it through the fuel lines to the engine. The fuel filter cleans the fuel, protecting the engine from contaminants, and the fuel injectors (or carburetor in older cars) precisely mix fuel with air for efficient combustion. Together, these components ensure smooth engine performance and efficient power generation, highlighting the importance of regular maintenance for optimal vehicle operation. Thank youuuu!!
