Injector Tester is a device that helps in testing of injectors before refilling. It helps in detecting any problem and helps in proper functioning of injectors. It helps in checking the amount of air or fuel being injected into the combustion chamber. This device is used to examine the quantity of fuel, air or both required by the combustion chamber.
Injector Tester which produces the results as per the test result should be chosen by firstly understanding the way it works. The Injector Tester displays the output in pulses and is a digital device. The output from the tester is in a form of voltage, square wave, or in an audio signal. A variety of different fuel injector testers is available in the market and the user can choose from those. However, it depends upon the application and requirement that the user might have.
The main function of a fuel injector tester is to check the performance and efficiency of the fuel injectors. It displays the output in pulse and operates with pulse gauge. Large LED screen/2 pulse modes. It is able to work well with almost any fuel injector.
A fuel injector tester can help in performing several functions. A user of this device can check for leakages, fuel lines obstructions, and fuel injector problems. Also they can provide diagnostic support to help in diagnosing some of the more difficult cases. When the fuel injector system of the automobile fails to operate properly, then an in-built error message is displayed. This can help the user know which line needs to be adjusted and therefore providing him guidance to repair or replace the fuel injector.
Fuel injector testing is not as simple as it appears to be on the surface. It involves a number of steps which should be followed systematically to get the desired results. Injector testers must be used carefully because of their sensitivity to various changes in pressure and temperature. Injector testing is usually carried out before any engine function. Prior to injecting fuel into the engine, a fuel injector tester is used to check the condition of the injectors and their functionality.
A fuel injector test is usually performed two to four times annually depending on the mileage and conditions. Before the engine starts, the fuel injector pressure is measured using the data loggers. The test is usually carried out without changing the fuel mixture. After a complete test is performed, all parameters must be compared with the data gathered during the test. Changes in any parameter should be noted.
If necessary, the manufacturer provides the fuel injector logs so that the tester can compare them. In case of significant differences, more tests are conducted until the discrepancy is resolved. The manufacturer typically provides data sheets along with the fuel injector logs to help testers avoid unnecessary adjustments. Injector adjustments are a must when it comes to vehicles that are undergoing regular maintenance. Injector adjustments help fuel injectors deliver higher fuel mixtures, lower emissions, as well as higher engine performance. This allows vehicles to work more efficiently and ultimately improve gas mileage and performance.
To ensure the highest level of fuel economy and efficiency, fuel injectors must be checked and adjusted at least twice a year. This is the time when they are tested to make sure that everything is working properly. In case there is any malfunction in the fuel injector, the vehicle should be evaluated for repair. This will prevent the vehicle from suffering premature failure. Therefore, with the help of a fuel injector tester, fuel efficiency will never be compromised.
