2. Break-in (mechanical run-in) - Wikipedia

   en.wikipedia.org/wiki/Break-in_(mechanical_run-in)

   In the past, the engine break-in period was very important to the overall life and durability of the engine. The break-in period required has changed over the years with improved piston ring materials and designs. In reference to small engines, the break-in period now (5–10 hours) is short in comparison with that of engines of the past.

3. Engine braking - Wikipedia

   en.wikipedia.org/wiki/Engine_braking

   The term "engine braking" refers to the braking effect that occurs in gasoline engines when the accelerator pedal is released. This causes fuel injection to cease and the throttle valve to close almost completely, greatly restricting forced airflow from, for example, a turbocharger.

4. Deglazing (engine mechanics) - Wikipedia

   en.wikipedia.org/wiki/Deglazing_(engine_mechanics)

   First, the lubricating oil in the engine will not adhere properly to the smooth surface, and in the absence of an oil film the resulting friction is increased. Secondly, while breaking in newly installed piston rings, a minute amount of wear must occur between rings and cylinder wall in order to seat the rings properly, and ensure a gas-tight seal.

6. Compression release engine brake - Wikipedia

   en.wikipedia.org/wiki/Compression_release_engine...

   A compression release engine brake, compression brake, or decompression brake is an engine braking mechanism installed on some diesel engines. When activated, it opens exhaust valves to the cylinders, right before the compression stroke ends, releasing the compressed gas trapped in the cylinders, and slowing the vehicle.

7. List of International Harvester/Navistar engines - Wikipedia

   These engines were used by IHC for some heavy-duty applications until 1935, although their own large engines (525 cu in (8.6 L) FBD and 648 cu in (10.6 L) FEB) had appeared in 1932. [6] The medium-duty 1930 A-series trucks received the all-new 278.7 cu in (4.6 L) FB-3 six-cylinder engine, with overhead valves and seven main bearings.

9. Automobile engine replacement - Wikipedia

   en.wikipedia.org/wiki/Automobile_engine_replacement

   Replacement engines are often used to make old cars more reliable for daily driving. Classic car hobbyists may also install reproductions of a rare powerplant in a classic car (this is most often seen in Mopar muscle cars that have the 426 Hemi installed into them). Aftermarket engines are used in many forms of motorsport.
