How do fuel injectors work?
How Do Fuel Injectors Work The fuel injector is a valve controlled either by springs or ECU (Electronic Control Unit), capable of opening and closing several time per second. The fuel is fetched from the fuel tank and transported to the injectors. Fuel lines are used for transportation.
How can I increase the life of my fuel injectors?
Driving a car hard, combined with short start stop journeys, will increase the wear and tear on injectors. Letting the engine cool down, before shutting it off, will increase the lifespan of the injectors. This will also, benefit the rest of the engine too.
Can fuel injectors cause driveability issues?
If the fuel injectors are not operating properly, then other parts of the engine will be affected as well. Therefore, if this precision is thrown off by restrictions; electrical problems or fuel problems, it can cause driveability issues.
What to do if your fuel injectors are not working?
Replacement fuel injector seals and washers are cheap and are, fairly easy to install. This can often fix the problem, and if you are handy with a wrench, it’s not that difficult to do. It is fairly inexpensive to have your car injectors cleaned and overhauled, by a professional. This involves inspection and cleaning of the injector.
How does the fuel injector work?
A modern fuel injection system works by atomising the fuel at high pressure, mixing it with clean air as it passes the inlet manifold, before entering the combustion chamber of each cylinder. The key element of the electronic modern fuel injection system is the word “electronic.”
How are fuel injectors controlled?
The amount of fuel injected is controlled by a flap valve located in the engine's air intake. The flap sits beneath the control unit and rises and falls in response to airflow - as you open the throttle, the 'suck' from the cylinders increases the airflow and the flap rises.
Does changing fuel injectors increase power?
The technical answer is yes; fuel injectors can add 10 extra horsepower at peak. However, for some car owners, that minimal difference does not offset the increased cost and complexity of switching to fuel injectors or upgrading the existing stock fuel injectors.
How do mechanical injectors work?
Mechanical fuel injection works with a simple throttle-controlled air valve and a fuel pump, usually running at one-half engine speed. After pulling fuel from a vented fuel tank, the fuel is delivered through a barrel valve that controls the amount of fuel with the position of the air valve.

How do throttle body injectors work?
With Throttle Body Injection (TBI), one or two injectors mounted in the throttle body spray fuel into the intake manifold. Fuel pressure is created by an electric fuel pump (usually mounted in or near the fuel tank), and the pressure is controlled by a regulator mounted on the throttle body.
How long do fuel injectors last?
In general, they're expected to last a pretty long time. Both Bosch and Delphi, two major manufacturers of automotive components, say their fuel injectors have a life expectancy of 1 billion cycles. Essentially, that means that the fuel injectors should last as long as the car does.
Do bigger injectors need a tune?
In general, injectors need a tune. Otherwise, your ECU is trying to drive the new, bigger injectors using the duty cycle and dead times for the old, smaller injectors, which means too much gas potentially at the wrong time (i.e. - running rich and potentially missing).
How much horsepower do injectors add?
Larger throttle body and injectors Depending on what type of engine you have, you can gain as much as 10-20 more horsepower and comparable torque. There is a catch, however. Go too large and you can lose power.
Is mechanical fuel injection Streetable?
Mechanical Fuel Injection Is Not Just for Race Cars Anymore Great horsepower or horrible driveability, your only options. Since its '40s conception, mechanical fuel injection (MFI) was strictly reserved for race cars. Street cars need not apply.
How do injector nozzles work?
Injector nozzles interact with Pistons in Combustion Chambers. When the Piston is drawn away from the Sparkplug, the Injector Nozzle sprays a fuel and air mixture into the Combustion Chamber. Injector Nozzles can be thought of as the “heart” of the engine.
What causes fuel injectors to fail?
Fuel injectors typically fail due to a buildup of contaminants such as carbon. Carbon build-up can cause a clogged or partially clogged injector, preventing the injector from closing all the way. This results in a drip that creates a misfire.
How to speed up a golf cart?
One of the easiest ways to speed up your golf cart is by increasing the tire size. If you don’t do anything else, but buy bigger tires, then you can speed up your golf cart by 2-4 miles an hour.
How does an electric golf cart work?
By upgrading these two restrictors, you can increase the power going to the motor . These devices are called the solenoid contactor relay and the electronic speed controller.
What is torque in golf carts?
Torque, or more accurately end torque in our use of the word, is the turning power of your wheels moving your golf cart. This torque is made by transferring the power from your engine to turning your wheels. The transmission, drive shaft, differential, and drive axles provide this transfer (or transmission ha!) of power.
What is the difference between an upgraded throttle body and an upgraded manifold?
These will allow for more air to pass into the opening of the motor. Upgraded throttle bodies may have more or bigger throttles to increase intake , while an upgraded manifold will have longer and more cylindrical tubes that allow for air to move faster to the combustion chamber.
Can you convert a Yamaha golf cart to a 4x4?
Lastly, very few Yamaha, E-Z-GO, or Club Car golf carts come in 4 wheel drive, but there a lot of aftermarket manufacturers that sell kits for converting your cart into a 4X4. This increases torque, and also helps you maintain better traction, so less of that torque is wasted on tire slippage.
Can you upgrade a golf cart to a single joint axle?
Each golf cart is different, but if your cart has jointed axles, meaning more than one piece to allow for movement of the suspension components , then you can upgrade to solid drive axles for a rear wheel driven cart or single joint axles for a front wheel drive.
Is a golf cart electric or gas?
Electric motors are quite a bit different from gas motors. If your Club Car, E-Z-GO, or Yamaha golf cart is electric, then making your golf cart go faster will be a very different challenge. Electric motors use induction, and don’t use the same physics as a gas motor.
How to get more speed out of golf cart?
Upgrading tires and increasing your tire size is by far one of the most economical and easiest ways to get more speed out of your golf cart. Equally applied, this is a great solution for both gas and electric golf carts. If you install a tire with a larger diameter on your golf cart, the end result is a higher top speed.
How fast can a golf cart go?
Most new and used golf carts are made to go a top speed of around 15 miles per hour . Although that is the perfect speed for most folks, there is an equal amount (if not more) of folks out there who are looking to increase their golf cart top speed and go faster than 20 MPH let's say.
How does a new battery work on a golf cart?
Simply put, most types of golf carts are designed to work with a range of different batteries. A new battery will increase a golf cart’s motor output. The result of the motor output increase is higher speed. Purchasing new batteries with a higher voltage maximum will increase your golf cart’s speed dramatically.
What is a series wound DC motor?
Series Wound DC Torque Motors are made with a larger field coil inside. A larger field coil inside of the motor , allows a larger magnetic field generation and holds the armature much more securely, thus producing greater torque. This is an excellent option if you're looking for more torque in your Club Car, EZGO or Yamaha golf cart, but are not so concerned about the speed.
What is torque in motors?
You know what 'speed' is, of course, but what is torque? Torque is the pulling power of the motor and is a function of current. So, basically, the higher the current, the more torque.
Is there a catch all solution to increasing golf cart speed?
A golf-cart weighed down by unnecessary clutter and debris is not a happy golf-cart! In closing, something to keep in mind is: There is no "catch-all" solution to increasing golf cart speed / golf cart power. There are many factors to consider such as, how the parts, pieces and changes interact with your golf cart.
Can you install a torque motor in an electric golf cart?

How does a fuel injector work?
While the carburetted system fetches low-pressure fuel from the fuel tank, these mechanical fuel injector systems pump a high-pressure fuel from the fuel tank , which is the basic principle of how the mechanical fuel injectors work. Once pumped from the fuel tank, the fuel then enters the accumulator. You can think of an accumulator as a buffer ...
What is the job of a mechanical fuel injector?
Its job is to distribute the fuel to the cylinders. Here, the delivery of the right amount of fuel into cylinders in the right amount of time is of the essence. Mechanical Fuel Injector. While entering inside the cylinder, the fuel and air must be mixed very precisely, with the right amount of both.
What happens when the fuel injector is deactivated?
After the completion of a certain cycle of fuel injection, the ECU stops sending the electronic signal to the fuel injector and so deactivating the electromagnet. As the electromagnet is deactivated, there is no more anything pushing the plunger outward the nozzle will be closed, causing the fuel spray to be stopped.
What is fuel injector?
The fuel injector is a valve controlled either by springs or ECU (Electronic Control Unit), capable of opening and closing several time per second. The fuel is fetched from the fuel tank and transported to the injectors. Fuel lines are used for transportation.
What is the mainspring in a fuel injector?
One is the mainspring and the other one called Plunger spring . The mainspring has the job to control the fuel inlet to the fuel injector, the fuel coming from the fuel pump is pressurized, and this pressure causes the mainspring to open and let the fuel inside the fuel injector.
Is there a mechanical mechanism for fuel injectors?
This is the mechanism used by the Electronic fuel injectors where an electronic circuit is used to open up the valve precisely and hence no mechanical mechanism is used here although the governing principle in both the mechanical and electronic fuel injectors is rather same.
Do fuel injectors need to be precise?
Not only does the amount of the fuel being injected needs to be precise, but the angle its placed at, the pressure and the spray pattern must also be very precise according to the need of perfect fuel to air ratio for the combustion. The types of fuel injectors differ for both petrol and diesel operated engines.
