Lexus Fuel Injector

Due to the limitations of the designs of carburetors, the industry has been forced to come up with a fuel system that complies with the fuel efficiency and emissions laws. The fuel system in many modern vehicles has really changed a lot, and fuel injection system took the place of the carburetors. Automotive carburetors were at first replaced by throttle body injection systems. In such type of injection system, the fuel injector is situated in the throttle body or air intake cavity. They didn’t require much engine redesigning since they were nearly a bolt-in carburetor replacement.

The arrival of new engine designs led to the utilization of multi-port fuel injection. This system features one injector in every cylinder, typically positioned at the mouth of the vehicle’s intake port. What’s good about this system is that it delivers quicker response and more precise fuel metering. The fuel injection system of most vehicles is made up of throttle body, which restricts the airflow; an electronic fuel pump; different engine sensors; a fuel filter and fuel injectors. The powertrain control module is responsible for making all the decisions in order to control the vehicle’s fuel injection system. The main task of the said system is to send exact amount of fuel to the engine under any operating conditions. It is more favorable than a carburetor since it has fewer maintenance requirements and it provides better control of the automobiles performance, emissions and fuel economy.

The fuel injector is perhaps, the most indispensable component of the fuel injection system. It is an electronically controlled device spraying and atomizing the fuel. This component holds an electrically operated valve which delivers the fuel to the engine. It is just like a solenoid into which gasoline for vehicles is metered. The fuel pump has the capability to open and close many times per second. It works this way: when electric current energizes the injector coil, an electromagnetic field is made and it moves a plunger that consequently opens the valve, letting the pressurized fuel to flow out of the tiny injector nozzle. The fuel is sprayed in a cone-shaped pattern because of the pintle valve’s shape. The quantity of fuel delivered to the engine is identified via the amount of time the injector remains open.

Through the fuel injector, direct injection system is performed. This means that the fuel is squirted directly to the car’s combustion chamber. To deliver the correct amount of fuel, the engine control unit is outfitted with many sensors.

Does your Lexus vehicle experiences rough idle and poor vehicle mileage and performance? Better have your Lexus fuel injectors checked and replaced if necessary. Malfunctioning Lexus fuel injectors may just need cleaning, but if not, replacement units should be purchased right away. Here at Parts Train, the Lexus fuel injectors that perfectly match the specifications of your Lexus model’s fuel injection system are always ready for immediate shipping.
