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.
A motor vehicle service or tune-up is a series of maintenance procedures carried out at a set time interval or after the vehicle has traveled a certain distance. The service intervals are specified by the vehicle manufacturer in a service schedule and some modern cars display the due date for the next service electronically on the instrument panel.
Engine braking is a generally accepted practice and can help save wear on friction brakes. It is even used in some motor sports to reduce the risk of the friction ...
A 1976 study included an evaluation of the armor required to contain the energy from 1 blade, 2 blade, and 4 blade fragments of the compressor and turbine stages of General Electric CF6 and Pratt & Whitney JT9D engines; although the 4 blade fragment was unlikely to occur, containing it would have required a steel plate 1.212 inches (30.8 mm ...

Maximum brake torque (MBT) is the use of optimal ignition timing to take advantage of an internal combustion engine's maximum power and efficiency. There is always an optimal spark timing for all operating conditions of an engine. MBT is ideal at wide-open throttle (WOT), but not desirable when the engine is at idle.
The salvage value is often forgotten, but is important, and is either the net cost or revenue for decommissioning the project. Some other topics that may be addressed in engineering economics are inflation, uncertainty, replacements, depreciation, resource depletion, taxes, tax credits, accounting, cost estimations, or capital financing.
