Which of the following does not depend on the fuel quantity injected *?
7. Which of the following does not depend on the fuel quantity injected? Explanation: The fuel is injected in the engine combustion chamber by the injection nozzle of an injector controlled by a solenoid-operated valve.
Which of the following is not the function of the fuel injection system?
A nozzle is used to atomize the fuel and break up into small particles. 9. Which of the following is not the function of the fuel injection system? Explanation: The functions of the fuel injection system are to filter the fuel, to time the fuel injection, to break up the fuel into small particles.
Which of the following methods use fuel injection?
Explanation: The methods used on fuel injection are air injection, mechanical injection and solid fuel injection.
What 3 things must occur for the fuel injection system to operate properly?
Fuel must be injected at the proper time, that is, the injection timing must be controlled and. The correct amount of fuel must be delivered to meet power requirement, that is, injection metering must be controlled.
What are the fuel system components?
The fuel system is made up of the fuel tank, pump, filter, and injectors or carburetor, and is responsible for delivering fuel to the engine as needed. Each component must perform flawlessly to achieve expected vehicle performance and reliability.
What are three types of fuel injection systems?
The three major types of fuel injection are known as throttle body injection, multiport injection, and direct injection.
Which is the most accurate petrol injection system?
Explanation: The most accurate petrol injection system is port injection. In this system, the injector sprays the fuel into each intake port on the manifold side of the inlet valve.
Which is the component of the fuel supply and injection system?
Abstract: The fuel injection system can be divided into low-pressure and high-pressure sides. The low-pressure components include the fuel tank, fuel supply pump and fuel filter. The high-pressure side components include a high pressure pump, accumulator, fuel injector and fuel injector nozzle.
What is fuel supply?
Fuel Supplies means the coal, oil, natural gas and other fuels that generation facilities consume to produce electricity and the transportation and transmission services used to deliver those fuels.
What are the different types of fuel injection?
The fuel injection types used in newer cars include four basic types:
- Single-point or throttle body injection.
- Port or multipoint fuel injection.
- Sequential fuel injection.
- Direct injection.
What is the function of fuel injection pump?
An Injection Pump is the device that pumps fuel into the cylinders of a diesel engine. Traditionally, the injection pump was driven indirectly from the crankshaft by gears, chains or a toothed belt (often the timing belt) that also drives the camshaft.
What is meant by fuel injection system?
Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of an injector. … There are two main functional principles of mixture formation systems for internal combustion engines: internal mixture formation, and external mixture formation.
What are the signs of a bad fuel injector?
Here are a few signs there might be something wrong with your fuel injectors.
- The Engine Misfires. Dirty fuel injectors may cause your vehicle’s engine to misfire. …
- Idling Gets Rough. …
- Your Gas Mileage Tanks. …
- The RPM Needle Starts to Dance. …
- Your Car Won’t Start.
How do you check fuel injector timing?
Hair line Test is a method of checking fuel pump timing by looking for the crank angle when the marking on plunger and its body coincides. When the unit is at TDC with both markings on plunger and its body coincide; the crank angle marking on flywheel will tell the exact position of fuel injection on timing diagram.
What controls the fuel injector pulse?
The (PCM) uses the trigger signal from the crankshaft position sensor; and/or camshaft position sensor to pulse the injectors.
