     A four-cycle engine works with 4 basic steps to a successful rotation of the crankshaft: the intake, compression, power and exhaust stroke. Each engine cylinder has four openings for the intake, exhaust, spark plug and fuel injection. The piston is driven by the engine's crankshaft whereas the intake and exhaust valves are driven by…

     Many of us come to a conclusion that if the vehicle's AC fails to blow crisp, cool air, the cause is a malfunctioning AC Compressor. This may not turn out to be true all the time, as the AC could have failed due to a fault in some other component. Therefore, instead of leaping…

     The fuel injector, an electrically operated gate, delivers fuel into the engine via its nozzle. The Engine Control Unit (ECU) dictates when the injector should inject fuel into the engine cylinder. It is advisable to clean the injectors every 25,000 to 30,000 miles to ensure that they do not get clogged. However, sometimes they…

The alternator supplies power to a vehicle’s electrical components like the headlights. The alternator tends to fail gradually, and its warning signs can signify future breakdown long before it occurs. Diagnosing a problematic alternator early can save you from a world of trouble. Avoid ignoring the tell-tale signs, and get the problem fixed before you’re…

Symptoms of a Worn Wheel Hub Bearing Signs of a worn wheel hub bearing vary in severity. Some may be difficult to detect, leading to damage before corrective action can be taken. The time frame in which damage occurs is linked to driving condition and/or the mechanical practices that were followed at installation. Noise is…

The crankshaft position sensor, otherwise called the engine speed sensor (ESS), monitors the rotation of the crankshaft. It can be identified as a thin, long, black cord, located next to the crankshaft. Based on the reading of the crankshaft position sensor, the Engine Control Unit (ECU) determines which cylinder should be fired with respect to…

The intercooler is fitted between the turbocharger and engine, and between two turbochargers in twin-turbo systems. The intercooler located near the engine is often called an aftercooler. Be it an intercooler or aftercooler, the function remains the same: to lower the temperature of the compressed air that is generated by the turbocharger. Intercoolers are also…
