ASE PS2 Test Preparation Guide: Engine Parts
● BEARINGS — Provide support for the crankshaft and camshaft. A thin film of oil between the bearings and shafts reduce friction and prevent wear. Most late model original equipment engine bearings are aluminum, or aluminum with a steel backing. Older engines typically use tri-metal (babbit and copper/lead over steel) rod and main bearings. Worn
ASE PS2 Test Preparation Guide: Emission Controls
● POSITIVE CRANKCASE VENTILATION (PCV) — Prevents crankcase blowby vapors from escaping into the atmosphere by siphoning the vapors back into the intake manifold so they can be reburned in the engine. Used since 1968 on most vehicles, the main component is a spring-loaded PCV valve that meters airflow. The PCV valve is usually mounted

● COMPRESSOR — Pumps refrigerant to the condenser and evaporator to cool the passenger compartment, and pulls refrigerant vapor from the evaporator to compress it. Most compressors are belt-driven (a few hybrids have electric compressors). A “magnetic clutch” on the compressor pulley cycles the compressor on and off as needed to control cooling. Some compressors
ASE PS2 Test Preparation Guide: Brakes
● DISC BRAKES — Use a pair of friction pads to squeeze against a flat disc or rotor when the brakes are applied. Most cars and light trucks since the early 1970s have front disc brakes, and many have rear disc brakes also. Disc brakes provide more stopping power than drum brakes, better cooling and
ASE PS2 Test Preparation Guide: Automatic Transmission/Transaxle
● AUTOMATIC TRANSMISSION — A transmission that shifts itself using engine RPM, load and other inputs to regulate shift points and gear engagement. Late model automatics have electronic/hydraulic controls operated by the Powertrain Control Module (PCM) or its own Transmission Control Module (TCM). Most late model automatics have five or six gears (speeds), though some
