Did you know the basic fuel system for your vehicle? I come across this vehicle basic fuel system from Honda newsletter and gain some knowledge and understanding on my own car fuel system.
One of the major components that power your car is the fuel system. The moment the engine starts, the fuel flows through a fuel line from the tank to the fuel pump. The fuel injection system supplies a clean air and fuel mixture that triggers the engine to run. Poor maintenance of the fuel system will cause weaker engine performance and if any of these parts breakdown, the engine could stop running.
While there are a number of things that can cause your fuel system to fail, the most prevalent one is dirt. This is why the fuel and air filter components are often said to be the vehicle’s front line defense because it prevents dirt from entering the fuel system. The fuel injection system is very susceptible to damage from dirt. When tiny foreign particles and deposits are allowed to build up inside, it prevents fuel from delivering to the engine. Proper maintenance of these parts is usually recommended by your car dealer during your scheduled service to keep the fuel system healthy.
Fuel Tank:
It holds the fuel supply and contains a sending unit which tells the fuel gauge how much fuel remains in the tank. It is important to ensure that the nozzle is clean so that the fuel is free of dirt when it is transferred into the tank.
Fuel Injection System:
The system mixes fuel with air in the internal combustion engine, with its main component being the fuel injector an electrically activated valve that sprays exactly the right amount of fuel to the intake valves of the engine. The pulse width, controlled by the vehicle’s ECU, determines the amount of time the fuel injector stays open.
Fuel Line:
It is a hose that regulates the flow of fuel and is connected to the fuel pump, fuel filter and fuel injectors. A clogged fuel line is like clogged arteries, and will cause difficulties in starting the car.
Fuel Pump:
While older vehicles uses a mechanical fuel pump, most modern cars now have electrical fuel pumps, which draws fuel
from the tank and deliver it under high pressure to the fuel injectors. The pump relies on adequate amount of fuel to keep it lubricated and is controlled by the ECU.
Fuel Filter:
It functions to trap contaminants before the fuel flows to the fuel pump. A blocked filter means debris can spread to the rest of the fuel system.
Air Cleaner:
Like the fuel filter, the air cleaner prevents particles and dirt from getting into the air/fuel mixture. A clean air filter helps your engine breathe better and helps you achieve better fuel efficiency.
