7 Symptoms of a Bad Mass Air Flow Sensor There are several symptoms of a bad MAF sensor, and not all of them are immediately obvious: Illuminated Check Engine Light: Performance and circuitdiagnostic trouble codesmay refer directly to the MAF sensor, but fuel trim and misfire codes can also ...
When oxygen struggles to reach the engine, fuel may not be burning off at an adequate rate. This can result in some of the fuel leaking through the system and out of your exhaust pipe. You may also hear popping sounds as super-heated fuel is expelled through your exhaust system...

Air pollution caused by fuel consumption in thermal power plants, factories, automobiles, etc. in the Asian region where industrial development is progressing, is also affecting Japan. Combustion of fossil fuels releases air pollutants such as nitrogen oxides (NOx) and volatile organic compounds (VOCs...
In the fuel combustion processes the maximum release of energy is obtained with the complete combustion with, minimum excess of air, closer to stoichiometric combustion, which generally leads to the exclusive formation of CO2, H2O, SO2 and N2 gases, respectively O2 and N2 of the air excess. In...
It also means changing the spark plug, spark plug wires and cleaning the fuel system at the manufacturer's scheduled interval. Doing this can improve mileage by more than 4 percent. If your check engine light is on (depending on the root cause), fixing that problem right away can sometimes...
The secondary air injection system, commonly found on Audi, BMW, Porsche and VW vehicles – and may be found on other vehicles – features an air pump, an exhaust manifold, an input check valve, vacuum control switch, an electrical input circuit for the vacuum control switch and tons of ...
Since the advent of fossil fuel-based combustion engines in the 18th century, cities around the world have enriched themselves through the mass production of goods. However, small particles generated from the engines’ operation have polluted the earth’s near-surface atmosphere, putting the natural...
