What is Delphi fuel injection?
ABOUT DELPHI
Delphi is an industry leader in diesel fuel injection systems and is continually developing advanced technologies to help manufacturers throughout the world meet new emissions requirements, while helping to improve fuel economy and enhance performance.
What is a valve injector?
In short, injectors are solenoid operated valves that use Pulse Width Modulated (PWM) signals from the Engine Control Unit to open or close a valve that permits or blocks fuel flow to the engine. A well designed fuel injector ensures quick and complete combustion of fuel.
How do I remove a Delphi injector?
You’re gonna have to screw that screw in tell it’s flush. Then about one turn like that and then back it out a little bit and hold it with a pair of pliers.
What is the function of injection valve?
The purpose of injection valves is to precisely inject the fuel quantity calculated by the control unit in all engine operating states. To ensure the fuel is atomised effectively while minimising condensation losses, a certain engine-specific distance and injection angle need to be observed.
What year did Harley switch to Delphi?
2001
With all the changes in 1999-2000, things were quite at Harley-Davidson for a few years, though in 2001 they switched to a better, Delphi EFI system on the bikes that were injected. 2001 was also the first year the Softail line was available with a fuel injected motor.
What is Delphi on Harley-Davidson?
The Delphi EMS system is the first “ion-sense” and hybrid engine controller based-technologies ever used on a motorcycle. The 2001 Harley-Davidson engine management system utilizes a Delphi engine control module, manifold absolute pressure (MAP) sensor and dual ignition coil.
How does a ECU control injector?
Electronic Control Unit (ECU)
The ECU is the brain of the operation. It uses engine RPM and signals from different sensors to meter the fuel. It does this by telling the fuel injectors when and how long to fire. The ECU often controls other functions like the fuel pump and ignition timing.
Is a fuel injector a valve?
A fuel injector is nothing but an electronically controlled valve. It is supplied with pressurized fuel by the fuel pump in your car, and it is capable of opening and closing many times per second.
How do you free a stuck injector?
How to Fix a Sticky or Stuck Fuel Injector – YouTube
Can you replace one diesel injector?
Replacing one does not save effort.
Any diesel vehicle professional will not be inconvenienced by having to install a set of injectors. If you are installing them at home, it may feel like more effort at first. But the more you do it, you will prefer to quickly install new injectors together.
What are the 3 types of injectors?
Your vehicle can be equipped with one of the three most common injection systems on the market. GDI (Direct injection), SDI (Semi-direct injection) or TBI (Throttle body injection).
What are the parts of injector?
Overview.
What year did Harley use Delphi fuel injection?
With all the changes in 1999-2000, things were quite at Harley-Davidson for a few years, though in 2001 they switched to a better, Delphi EFI system on the bikes that were injected. 2001 was also the first year the Softail line was available with a fuel injected motor.
How much horsepower does a Harley 88 have?
| Max HP | Max- Torque | Carb/EFI |
|---|---|---|
| 144 | 121 | S&S Super D |
| 109 | 104 | 50mm SE w/PC III |
| 71 | 91 | HD stock |
| 66 | 82 | HD stock |
What year did Harley start using Delphi fuel injection?
What size are stock Harley injectors?
We use stock injectors in the great majority of the mild 107″ and 110″ big bore applications, however if we increase the size of the throttle body or in higher output builds we generally use the 5.3gm injector.
What sensor controls the injectors?
The injector control pressure sensor is an engine management component that is commonly found on diesel engines. As its name implies, it is an electronic sensor that monitors the fuel pressure going to the injectors.
What does a faulty fuel injector cause?
The Engine Misfires
Dirty fuel injectors may cause your vehicle’s engine to misfire. This problem makes the motor feel as though it is sputtering — sending vibrations through the car. Such misfires can happen when a fuel injector problem mixes up the delicate balance between fuel and air entering the engine.
What are the symptoms of a stuck open injector?
So, what are the symptoms of a stuck open fuel injector? The most common ones are a sudden illumination of check engine light, rough idling, and frequent engine vibrations.
How do you tell if you have a stuck injector?
Dirty Fuel Injector Symptoms
- The Engine Misfires. Dirty fuel injectors may cause your vehicle’s engine to misfire.
- Idling Gets Rough. Does your vehicle sputter and shake when you’re at a stop sign or sitting in traffic?
- Your Gas Mileage Tanks.
- The RPM Needle Starts to Dance.
- Your Car Won’t Start.
How long should diesel injectors last?
Diesel fuel injectors generally have a shorter lifespan than their predecessors, meaning they need to be replaced more frequently for optimal performance. The life expectancy of a good quality diesel fuel injector is around 150,000 kilometres.
Is it better to clean fuel injectors or replace?
Injector Replacement or Injector Cleaning? Fuel injectors should be cleaned at least once every 36 months, or 45,000 miles. Replacing weak or worn-out engine parts without improving performance is not a good idea in general. However, cleaning out dirty injectors may gain a different perspective on engine health.
What are the two types of injectors?
There are basically two types of non-hydraulic common rail injectors — electromechanical solenoid base and Piezo. Piezos are typically found on newer applications, depending on the vehicle.
What are the 2 types of fuel systems?
Two types of fuel pumps are used in automobiles; mechanical and electric. As engines moved away from carburettors and towards fuel injection, mechanical fuel pumps were replaced with electric fuel pumps, because fuel injection systems operate more efficiently at higher fuel pressures than mechanical pumps can generate.
What are the 5 components of fuel system?
Your car’s fuel system has five main components: the fuel tank, fuel lines, fuel filters, fuel pumps, and fuel injectors.
