11. The term compression-ignition refers to the fact that the fuel is ignited only by the high temperature of the compressed charge, and is one characteristic of the diesel engine cycle. Based on this description, which statement is correct? (A) When the fuel is ignited by the high temperature of expansion stroke, the engine is referred to as the compression ignition engine. (B) When the ignition of fuel is provided by the spark, the engine is referred to as the compression ignition engine. (C) When the fuel is ignited by the temperature of compressed stroke of a reciprocal engine, it is called the compression ignition engine. (D) When the compression charge could provide the high temperature for ignition, the fuel can not be automatically ignited in a compression ignition engine.

12. Magneticbearings are used in applications where noise and vibration are important considerations or where lubricants are not acceptable. Like the hydrostatic bearings they do not require shaft rotation to generated bearing support forces. The rotor is floated in the space and levitated by magnetic forces, which are generated within the bearing by magnets. Therefore, (A) the air is necessary to be used as the lubricant to provide the film pressure for magnetic bearings. (B) the air is necessary to be used as the lubricant to reduce the noise and vibration for magnetic bearings. (C) the shaft rotation is important for generating the supporting forces for the magnetic bearings. (D) the magnetic forces are generated in the magnetic bearing to support the load of bearing.
