Both Technicians A and B d. Neither Technician A nor B

Task 8 - Induction Systems In order for combustion to take place an induction system is required to feed fuel and air into the cylinder of an engine. To improve efficiency and performance spark ignition (SI) engines are now adopting compression ignition (CI) engine technology by injecting fuel directly into the cylinder just before the point of ignition however these engines still require an air induction system. Carburettors: before fuel injection technology had been fully developed carburettors (carbs) were used to create a fuel/air ratio at different engine speeds and loads. A cold start facility was also fitted albeit manually operated. The demand for more performance has meant the fixed choke carb' was no longer suitable. More complex carbs' were developed (twin choke) as well as variable choke (constant depression) carbs which used engine vacuum (during throttle opening) to vary the size of choke according to operating requirements.

Fourth task:During a visit to a factory, I came across a compressor and a compressed air networkUsed to operate a number of compressed air systems. The following notes were collected:• The compressor is relatively old.• The compressor room was very hot.• The compressor room was relatively close to the compressed air systems• The pressure at the outlet of the compressor was 8 bar.• The pressure in the pneumatic systems reached 7.5 bar.• Compressor on/off cycles every 40-55 seconds.Prepare a short, high-level recommendation note about actions that can be taken immediately, and measurements you might plan to assess potential energy savings opportunities.
