This little powerhouse is responsible for drawing fuel from the fuel tank and delivering it to the fuel injectors under pressure. Without a properly functioning fuel pump, your engine won't get the fuel it needs, and you'll be going nowhere fast! Next, we have the fuel injectors. These are the spray nozzles that squirt fuel into the engine's intake manifold or directly into the combustion chamber. The ECU controls the fuel injectors, determining how much fuel to inject and when. Think of them as the precise sprayers, ensuring the right amount of fuel gets delivered at the right time. Then, we have the throttle position sensor (TPS). This sensor tells the ECU how far open the throttle is. Based on this information, the ECU adjusts the fuel delivery accordingly. When you twist the throttle, the TPS sends a signal to the ECU, which then instructs the fuel injectors to deliver more fuel, giving you that instant burst of power. The engine control unit (ECU) is the brain of the operation. It receives signals from various sensors and, based on these inputs, controls the fuel injectors, ignition timing, and other engine functions. It's like the conductor of an orchestra, ensuring everything works together harmoniously. Finally, we have various sensors that provide the ECU with vital information about the engine's operating conditions. These sensors measure things like engine temperature, air intake, and oxygen levels in the exhaust. The ECU uses this information to fine-tune the fuel injection system for optimal performance and efficiency. So, as you can see, each of these components plays a vital role in ensuring your Motor Lagenda 115Z runs at its best. Taking care of these components through regular maintenance is key to keeping your ride in top shape.
