Question 261Motor Plants - Assistant Engineer

The correct answer is C) a spray of fuel into a turbulence combustion chamber. This is correct because the illustration MO-0020 likely depicts a diesel engine, where the combustion of fuel is initiated by spraying fuel into a turbulence combustion chamber. This process allows for efficient mixing of the fuel and air, leading to complete combustion. The other answer choices are incorrect because: A) fuel injection using a unit injector is more common in modern high-speed diesel engines, B) individual Bosch fuel pumps are used to supply fuel to the injectors, and D) an "energy cell" is not a standard component of a diesel engine's combustion system.
