A motorcycle's fuel tank is the main storage container for fuel. The fuel pump, which is a crucial component of the fuel tank, uses fuel lines to deliver fuel at high pressure to the engine's fuel injectors. The fuel injectors spray a fine mist of fuel into the combustion chamber of each cylinder, which is then ignited to produce power for the driven wheels. When filling up a motorcycle's fuel tank, it is important to ensure that fuel does not spill onto the paint. Some motorcycles have a petcock, or valve, that allows riders to turn off the fuel flow when the bike is parked. The fuel pump can also be shut off in the event of an accident to reduce the likelihood of an engine fire.

What You'll Learn
The fuel tank is the main storage for fuel
The fuel tank is the main storage container for the fuel that powers the motorcycle. It is an essential component of the fuel system, which is responsible for storing and delivering fuel to the cylinder chamber, where it is combined with air, evaporated, and burned to produce energy. The fuel tank holds the fuel, which is then delivered to the cylinder chamber for combustion by a fuel pump.
The fuel tank is typically located above the carburetor float bowl, and in older models, gravity was used to feed fuel to the carburetor. Modern motorcycles have added a petcock or valve that allows riders to turn off the fuel flow when the bike is parked, preventing fuel leaks and overflow. The petcock has three settings: OFF, RUN, and PRIME or FUEL, and RESERVE. When the fuel level is low, switching to the reserve setting allows access to extra fuel, providing enough to reach a gas station.
The fuel pump plays a crucial role in delivering fuel from the tank to the engine's fuel injectors. It operates at high pressure and is controlled by the motorcycle's ECU. In case of an accident, the fuel pump can be shut off to reduce the risk of an engine fire. The fuel injectors, driven by the fuel pump, spray a fine mist of fuel into the combustion chamber, creating a fuel and air mixture that is ignited to produce power for the driven wheels.
The fuel tank's capacity can vary, and it is important to monitor fuel levels to avoid running out of fuel unexpectedly. Some motorcycles have a fuel gauge to indicate the fuel level, while others may have a fuel level sensor that shuts off the fuel pump when the level is low, giving the illusion of running out of gas until the reserve setting is activated. Understanding the fuel tank's capacity and the range it provides is essential for riders to plan their refuelling stops accordingly.

Fuel injectors spray a mist of fuel into the combustion chamber
The fuel injector is a crucial component of a motorcycle's fuel system. Fuel injectors are driven by the fuel pump, which uses fuel lines to deliver fuel at high pressure to the engine's injectors. The injectors then spray a fine mist of fuel into the combustion chamber of each cylinder or throttle body, depending on the design. This process is known as fuel injection, and it involves the introduction of fuel into an internal combustion engine through the fuel injector.
The fuel injector is essentially a spray nozzle that performs the final stage of delivering fuel into the engine. It is located in the combustion chamber, inlet manifold, or, less commonly, the throttle body. The injector may also control the metering and is, in such cases, called an injection valve. Injectors that perform all three functions are called unit injectors.
Direct injection involves injecting fuel directly into the main combustion chamber of each cylinder. The air and fuel are mixed only inside the combustion chamber, and only air is sucked into the engine during the intake stroke. This injection scheme is always intermittent, either sequentially or cylinder-individual. The injection can be done with a blast of air or hydraulically, with the latter being more common in automotive engines.
The common-rail system is a type of fuel injection system where fuel from the tank is supplied to a common header (the accumulator) and then sent through tubing to the injectors, which inject it into the combustion chambers. The accumulator helps maintain pressure and return excess fuel to the fuel tank. Third-generation common-rail diesels use piezoelectric injectors for increased precision, achieving fuel pressures of up to 300 MPa or 44,000 psi.

Fuel lines connect all fuel system components
The fuel system in a motorcycle has several components, including the fuel tank, fuel pump, fuel injectors, and fuel lines. Fuel lines play a crucial role in connecting these components and facilitating the flow of fuel from the tank to the engine.
Fuel lines are responsible for delivering fuel from the tank to the engine's fuel injectors. They are connected to the fuel pump, which controls the flow and pressure of the fuel. The fuel pump is a vital component of the fuel system, using an electric motor to deliver fuel at high pressure through the fuel lines. In the event of an accident, the fuel pump can be shut off to reduce the risk of an engine fire.
The fuel injectors are another key component in the fuel system. They are essentially nozzles with attached valves, and their function is to spray a fine mist of fuel into the combustion chamber of each cylinder or throttle body, depending on the motorcycle's design. The fuel injectors are driven by the fuel pump, which ensures that the fuel and air mixture is sprayed into the combustion chamber, ready for ignition to produce power for the driven wheels.
The fuel lines connect the fuel tank, fuel pump, and fuel injectors, ensuring a continuous flow of fuel throughout the system. This network of fuel lines is designed to withstand high pressure and maintain the integrity of the fuel flow. Without the fuel lines, the various components of the fuel system would not be able to function cohesively, and the motorcycle would not be able to operate efficiently.
In addition to their functional role, fuel lines also contribute to the safety of the motorcycle. They are designed to meet specific standards and regulations to prevent leaks and ensure the secure transportation of fuel. Regular maintenance and inspections of the fuel lines are crucial to identify any potential issues, such as blockages or leaks, and ensure the overall performance and longevity of the fuel system.

The fuel pump delivers fuel to the engine
The fuel pump is a crucial component of a motorcycle's fuel tank. It delivers fuel at high pressure to the engine's fuel injectors. The fuel pump's operation is controlled by the motorcycle's ECU (Engine Control Unit). In newer models, the fuel pump is built into the petcock, with settings for OFF, RUN, and PRIME or RESERVE. RUN activates the fuel pump, while PRIME or RESERVE switches to a gravity feed in case of fuel pump failure.
The fuel pump ensures a steady supply of fuel to the engine, maintaining consistent fuel pressure. When the pump fails to function properly, the motorcycle may experience starting issues, abrupt increases in acceleration, loss of power when accelerating, and intermittent stuttering at higher speeds. These symptoms are indicative of the pump's inability to provide adequate fuel delivery to the engine.
The fuel pump works in conjunction with the fuel injectors, which are driven by the pump's pressure. The injectors act as nozzles, spraying a fine mist of fuel into the combustion chamber of each cylinder or throttle body. This fuel-air mixture is then ignited to produce power for the driven wheels.
In older motorcycle models, gravity played a significant role in fuel delivery. The fuel tank was positioned above the carburetor float bowl, allowing gravity to feed fuel downwards. However, modern motorcycles have replaced this system with fuel pumps to ensure more precise fuel delivery and pressure control.
The fuel pump's role in delivering fuel to the engine is critical for the motorcycle's performance and safety. In the event of an accident, the fuel pump can be shut off to reduce the risk of an engine fire, demonstrating its essential function in the fuel system.

The reserve tank provides extra fuel to reach a gas station
The fuel system on a motorcycle has two main functions: storing fuel and delivering it to the cylinder chamber. The fuel tank is where the fuel is stored and from where it is delivered to the cylinder chamber for combustion. The fuel pump is a crucial component of the fuel tank. It uses fuel lines to deliver fuel at high pressure to the engine's fuel injectors.
The reserve tank is not a separate small tank but rather an overflow section of the main fuel tank. The amount of extra fuel provided by the reserve tank varies depending on the motorcycle model. For example, the reserve on a 650 V-star motorcycle is just over a gallon, which translates to approximately 40 extra miles.
It is important to note that the reserve tank is not meant to be used as a primary fuel source. It is intended for emergency situations when the rider needs to reach a gas station. Riding on reserve with a full tank can cause issues, as the fuel can only be drawn from the bottom of the tank, leading to potential contamination by dirt, rust, or other debris.
