Where is the throttle body injection system located?
Fuel is delivered to the throttle body injection system by an electric fuel pump located in the fuel tank. This pump supplies fuel pressure in sufficient volume to meet the engine’s fuel requirement through all load conditions.
What kind of fuel injection system does Mercedes Benz use?
. The fuel injection system used on all Mercedes-Benz gasoline engine vehicles uses a basic CIS injection system for fuel delivery and electronic controls for mixture correction functions.
Where are the fuel pumps located on a Mercedes 560?
The 420 and 560 models are equipped with 2 fuel pumps. All other models use one pump. On all models, the fuel pumps are located in front of the rear axle on the right side on the frame floor. On all models, a diaphragm damper is integrated in the fuel pumps.
How does the cold start valve work on a Mercedes Benz?
Cold start valve operation depends on coolant temperature and cranking speed signal. Voltage is supplied by the fuel pump relay. The length of time during which the cold start valve injects fuel is dependent on the coolant temperature. If the engine starts before the cold-start valve completes its cycle, cold start injection is canceled.
. The fuel injection system used on all Mercedes-Benz gasoline engine vehicles uses a basic CIS injection system for fuel delivery and electronic controls for mixture correction functions.
Why is my fuel injection system plugged in?
The electric fuel pump installed for a fuel injection system will draw considerable more volume of fuel from your tank than your old system did. If there are any contaminants in the tank this many times will plug up or greatly restrict the flow of fuel to the system causing many issues. Step by Step Troubleshooting guide.
Where is the throttle body injection ( TBI ) sensor?
Throttle body injection (TBI) units. The next generation of fuel delivers to the engines. The main control sensor is the oxygen (O-2) sensor, which is located in the exhaust pipe. The sensor tells the ECM the amount of oxygen in the exhaust gas, and the ECM changes the air/fuel ratio to the engine by controlling the fuel injector.
Where is the fuel injected in an engine?
Fuel under pressure is injected in a conical spray pattern at the walls of the throttle body bore above the throttle valve, or into the manifold or engine cylinder. The fuel which is not used by the injectors passes through the pressure regulator before being returned to the fuel tank.
What is the throttle body on a Nissan?
The throttle body is the part of the car’s air intake system that controls the amount of air flowing into the engine when the accelerator pedal is pressed. Without a fully functioning Nissan throttle body, air will not get drawn into the engine, which is necessary to create a proper fuel mixture to ignite combustion.
What kind of fuel injector does a Nissan use?
Until the 1980s, the most popular method of fuel delivery for Nissan was the carburetor. Then came the design of fuel injection. Nissan originally had a specific line of fuel injectors built only for Nissan vehicles, but now you can buy fuel injectors for your Nissan through a variety of manufacturers.
How do you clean a Nissan fuel injector?
How To Clean Nissan Fuel Injectors. Fill a cup with about 5 ounces of Sea Foam and slowly insert the hose into the cup, creating a vacuum-like effect. The hose will suck up the Sea Foam. Plug the vacuum line back into the intake manifold. Turn off your engine and let the Nissan sit for at least 20 minutes.
Where is the throttle body on a fuel injected engine?
But that’s enough about carburetors… On a fuel-injected engine the throttle body is normally located between the air filter and the intake manifold, and is connected to the gas pedal mechanically with a cable, or electronically by wire.
Why do you need a throttle position sensor?
Average rating from 93 customers who received a Throttle Position Sensor Replacement. The throttle position sensor (TPS) is part of your vehicle’s fuel management system and helps ensure that the correct mixture of air and fuel is delivered to your engine.
How is TPS used in a fuel injection system?
The TPS provides the most direct signal to the fuel injection system of what power demands are being made by the engine. The TPS signal is continually measured and combined many times per second with other data such as air temperature, engine RPM, air mass flow, and how quickly the throttle position changes.
