What is electronic diesel injection system?
Electronic Diesel Control is a diesel engine fuel injection control system for the precise metering and delivery of fuel into the combustion chamber of modern diesel engines used in trucks and cars.
How do electronic injectors work?
Electronic fuel injection allows for extremely precise control over how much fuel is sprayed into the cylinders. The fuel pressure regulator knows how much fuel to let through to the injectors via a signal from the mass airflow sensor (MAF). This sensor tracks how much air is entering the engine at any given time.
What is electronic injector?
An electronic unit injector is a unit injector that has electronic control. Its camshaft-driven delivery of pressurized fuel coupled with management of the internal operations’ timing by an engine control unit allows electronic unit injectors to achieve certain benefits over conventional unit injectors.
What are the six types of diesel injectors?
Types of Diesel Fuel Injection Systems
- Throttle Body Injection. Throttle body injection (TBI) is very similar to carburetion; so similar, in fact, that many throttle body injection units were actually adapted from gas carburetors.
- Multipoint Injection.
- Direct Injection.
- Common Rail Injection.
What are the advantages of electronic diesel control?
The passenger car equipped with the electronic control diesel engine mentioned above provides the following four additional advantages: (1) Good acceleration response; (2) Idle speed control which is affected by engine coolant temperature, on-off of the air conditioning compressor and battery voltage; (3) Cruise …
What are the advantages of electronic fuel injection?
EFI-equipped engines provide higher power and torque than a carbureted version of the same engine. They optimize air/fuel ratios and ignition timing while compensating for other factors to maintain continuous optimum performance.
What is the disadvantage of electronic fuel injection?
Disadvantages of Electronic Fuel Injection System High maintenance cost. Difficulty in servicing. Possibility of malfunction of some sensors.
What is the benefit of using electronic injection system?
EFI systems maintain optimum air/fuel ratios, eliminating random engine stoppages, oiled spark plugs and other problems associated with sub-optimal ratios. Carburetors tend to need frequent adjustments; EFI engines eliminate the need for repeated modifications.
What type of injector is used in a diesel engine?
There are three common architectures of diesel fuel injection systems: Pump-Line-Nozzle. Unit Injector. Common Rail.
What are the types of electronic fuel injection system?
Types of Fuel Injection
- Single-Point or Throttle Body Injection.
- Port or Multi-Point Fuel Injection.
- Sequential Fuel Injection.
- Direct Injection.
What are the types of electronic diesel injection control?
The main types of injection systems include pump-line-nozzle, unit injector, and common rail. Modern injection systems reach very high injection pressures, and utilize sophisticated electronic control methods.
What is an electronic fuel injection?
Electronic fuel injection is a type of technology and mechanical structure that supplies fuel to an engine. These systems are most common in automobiles and trucks. All cars sold today in the United States are required to have electronic injection systems in large part because of these systems’ overall…
What is a diesel fuel injector?
A diesel fuel injector is a very important component of the diesel car’s engine. The diesel engine, unlike the gasoline engine, injects fuel directly into the cylinder. This exposes it to heat and pressure, which might, overtime, damage the fuel injector or decrease its productivity.
How does a fuel injection system work?
Fuel injection systems either work via a throttle body containing as few as 2 injectors, or go straight into the port with one injector per cylinder. The injectors themselves spray gas into the combustion chamber like a spray bottle, allowing the gas to mix with air before ignition. The fuel is then ignited and the engine keeps on moving.
What is a diesel fuel pump?
The diesel fuel pump is a fairly complex and sturdy mechanism. In fact, it is the most complex diesel engine part. Additionally, a diesel fuel pump must be durable enough that it can withstand the pressure of the compressed air, and the heat of the injection process.
