The diesel market is growing at a rapid rate from year to year as the requirement for reliable heavy-duty and light-duty vehicles augment mostly in the secondary and third world countries. As the infrastructure improves around the globe, the need for dependable and sturdy trucks grows too. It has been predicted that diesel sales will grow triple in the next 10 years accounting for more than 10 percent of all automobile sales up from 3.6 percent just 15 years ago in 2005. From 2000 till 2005, the number of diesel registrations increased more than 80 percent exceeding to 550,000 vehicles. From the year 2005 to the year 2015, the figure further increased to another 67 percent.
How Does a Fuel Injector Work?
Fuel injectors are basically small electrical components that are useful in delivering fuel through a spray directly into the ingestion manifold in front of the intake valve in a diesel engine. Diesel fuel injectors are complicated; the injector comes with a high micron filter which is on the top inlet side corresponding to small needle sized holes on the bottom. It helps atomize the diesel fuel. The diesel fuel works a lubricating source for the injector’s internal parts. The prime source that leads to the failure of injectors is water in the fuel. As water mixed in fuel moves the lubricating traits the internal parts erode quickly and the injector fails to work promptly.
Injectors are a crucial engine component. The valve of the injector opens and closes at similar RPM as that of a diesel engine. The standard RPM for diesel engines in the North American region is approx 1800. This equated to about 140,000 times an hour! Furthermore to water being mixed in the fuel, injectors are subjected to dirt and carbon introduced into the unit through a poor air filtering element. The type of fuel, additives and grade used also have a considerable impact on the life expectancy of the fuel injector. Learn more about GM Diesel Fuel Injector 97729095 today!
The Engine Control Module actually runs the fuel injectors as it does in most electrical diesel engines. The diesel injectors have constant power as the key is turned on regardless if the engine is turned over. ECM grounds the injector, completing the circuit, which causes the injector nozzle to open. The ECM receives information from different control sensors that help determine the period of time the injectors require to be grounded to inject an accurate amount of duel given the horsepower output requirement from the engine.
What Options Do You Have?
Diesel fuel injectors are made available in a variety of sizes and shapes and even working conditions. Any good store can certainly help you identify the best type of fuel injector based on your diesel engine requirements. Ensure to know the difference between New, Refurbished, OEM, Used, and Remanufactured injectors. Any injector should come with a warranty and quality control documentation.
