Question 36 QMED03 - Oiler

The Correct Answer is B **Explanation for Option B (turbocharger):** Many modern diesel engines utilize a turbocharger (or sometimes a supercharger) to increase the air density entering the cylinders. This process, known as forced induction, allows more fuel to be burned efficiently, significantly boosting the engine's power output and overall efficiency. A turbocharger uses the engine's exhaust gases to spin a turbine, which in turn spins a compressor that forces more air into the engine's intake. **Explanation for Incorrect Options:** * **A) slam charger:** This term is not a standard or recognized component used for forced induction in diesel engines. * **C) fuel atomizer:** While atomization is crucial for mixing fuel and air, a fuel atomizer (which is essentially the function of a fuel injector) is responsible for breaking the diesel fuel into fine droplets, not for supercharging the air intake. * **D) fuel injector:** A fuel injector is a device that delivers and sprays fuel directly into the combustion chamber or pre-combustion chamber. It is an essential component of the fuel system but does not supercharge (pressurize) the intake air.
