2. Serpentine belt - Wikipedia

   en.wikipedia.org/wiki/Serpentine_belt

   Serpentine belt (foreground) and dual vee belt (background) on a bus engine Belt tensioner providing pressure against the back of a serpentine belt in an automobile engine. A serpentine belt (or drive belt [1]) is a single, continuous belt used to drive multiple peripheral devices in an automotive engine, such as an alternator, power steering pump, water pump, air conditioning compressor, air ...

3. BAS hybrid - Wikipedia

   en.wikipedia.org/wiki/BAS_hybrid

   The BAS is in the 2008–2009 Chevrolet Malibu Hybrid. [3] It operates on the same principle as Toyota's THS-M using a 36-volt electrical system (at 42–45 volts). According to the EPA, the 2009 Saturn Vue BAS hybrid garners an improvement of 32% city (19>25mpg) and 24% highway (26>32mpg) making the combined economy improvement 27% (22>28mpg ...

   Chain tensioner on a single-speed bicycle Belt tensioner on a belt-drive bicycle Hydraulic bolt tensioner Hydraulic Puller-tensioner . A tensioner is a device that applies a force to create or maintain tension. The force may be applied parallel to, as in the case of a hydraulic bolt tensioner, or perpendicular to, as in the case of a spring ...

5. Chrysler 1.8, 2.0 & 2.4 engine - Wikipedia

   en.wikipedia.org/wiki/Chrysler_1.8,_2.0_&_2.4_engine

   A timing belt is used to drive the valvetrain. Early production 2.0 L engines used a hydraulic tensioner to tension the timing belt. 2000 and 2001 engines used a mechanical spring-loaded tensioner that tended to wear out prematurely, causing serious valve and piston damage upon belt failure due to the interference design of the engine. 2002 and ...

6. Oil pump (internal combustion engine) - Wikipedia

   en.wikipedia.org/wiki/Oil_pump_(internal...

   For reliability, it is rare to use an external drive mechanism, either a separate belt drive or external gears, although camshaft-driven pumps often rely on the same timing belt. Additional separate belts are sometimes used where dry sump pumps have been added to engines during tuning. Electric oil pumps are not used, again for reliability.

7. Timing belt (camshaft) - Wikipedia

   en.wikipedia.org/wiki/Timing_belt_(camshaft)

   Aside from the belt/chain itself, also common is a failure of the tensioner, and/or the various gear and idler bearings, causing the belt/chain to derail. Furthermore, in engines where the timing belt drives the water pump, failure of the water pump can cause the pump to seize, which can break the timing belt or chain.
