A few decades ago, transportation was not a flourishing field of technology and advancement. There were very few numbers of cars and trucks which travel on the road and there was not much pollution tainting the peaceful environment. But today, a number of locomotive manufacturing organizations have emerged producing various kinds of vehicles with extraordinary comforts and sophistication. What shall be the reason behind such towering advancements? Undoubtedly, it is due to the invention of various types of engines with robust efficiency. Let’s consider an internal combustion engine which contains many unique parts like combustion chamber, piston, fuel pump, fuel injectors etc.

Fuel injectors play a vital role in an internal combustion engine by spraying regulated amount of fuel into the cylinder. The improper functioning of the fuel injector shall be characterized by engine vibration and misfires, strong fuel odor, fuel leaks and decreased fuel economy. The fuel injector consists of an electromagnetic coil which is energized by the power supply to perform its function. It also contains a sealing mechanism at its bottom with a pintle or disc. The electromagnetic coil is fed with power when the key is turned on. The repeated push and pull motion of the pintle opens and closes the valve of the cylinder simultaneously and this is done for more than 100 times a minute. In the engines of heavy load trucks and race cars, this number shall be still higher.

Moreover, the tip of the fuel injector sprays the fuel inside the cylinder with the help of the force from the pressure chamber. It is recommended to clean the fuel injectors for every 30000 miles which can prevent your engine tremors and loss of fuel in large scale. The engines use a variety of fuels which contain different amount of hydrocarbons and additives. These substances when heated by the temperature inside the engine evaporate at various temperatures causing the sediments to get a hold on the fuel injectors. Whenever the engine is turned off the tip of the injector always contains a drop of the fuel which also reacts with the sediment hydrocarbons and making the deposition stronger thus hindering the performance of the engine. This kind of coagulated hydrocarbon deposits can be cleared by using appropriate fuel system cleaner which is manufactured specifically for that purposes. Listed below are the most prevalent fuel system cleaner products in the market which provides flawless cleanliness.
