1. Purpose of the research Implement injector tester and timer button in mechanical, electrical for Correct Use Hypothesis: if humans contribute to the contamination of unconsciously by technological convenience. Give solution with the same! 2. Procedures Needed human and material resources. Besides a ventilated area with excellent ventilation. Having basic knowledge of electricity and automobile electrical systems. 3. Data This device is intended total replacement bulbs and multimeters tests relating to auto injectors of this system is important since in automotive history have been looking for improvements, part of technological development and of necessity, be have been implemented in complex systems such as electronic fuel injection, but what if our system does not work properly? Humans would contribute to contamination of the ozone layer, this natural process accelerate global warming. Hey there a social problem today becomes a global problem. Here we can see that, sophisticated equipment, are of little technical solution with a higher cost. Not to mention that the technician who works on the vehicle: save time in making a diagnosis which will be successful. 4. Conclusions The solution: provide the necessary equipment that is available to countries that do not have low resource enough. Through a reliable and safe product for the sole purpose of showing that young researchers are able to provide improved technology in the automotive industry with no expectation of this project. You should use this factor as important in society: it is the technology for the environment thereby demonstrates the certainty of our hypothesis.
