The objective of knock control strategies is to attempt to optimize the trade-off between protecting the engine from damaging knock events and maximizing the engine's output torque. Knock events are an independent random process. [8] It is impossible to design knock controllers in a deterministic platform. A single time history simulation or ...
Engine knock or pinging occurs when some of the unburnt gases ahead of the flame in an SI engine spontaneously ignite. This gas is compressed as the flame propagates and the pressure in the combustion chamber rises. The high pressure and corresponding high temperature of unburnt reactants can cause them to spontaneously ignite.
This engine is a turbocharged boxer-four with common rail fuel injection. [4] [17] [18] [19] Ferrari used flat-twelve engines for various Formula One cars in the 1970s. A road car flat-twelve engine (using a 180-degree V12 configuration) was used for the 1973-1984 Ferrari Berlinetta Boxer, 1984-1996 Ferrari Testarossa and their derivatives. [20]
A driver or carrier who specializes in, or a load composed of many different types of cargo, each typically weighing less than 10,000 pounds (4,500 kg), with many different destinations. Generally involves the use of terminal facilities to break and consolidate shipments. A LTL driver normally has a dedicated or regional route. [10] [25] [26 ...

The 1712 Newcomen atmospheric engine (the first steam engine) used chain drive instead of a connecting rod, since the piston only produced force in one direction. [11] However, most steam engines after this are double-acting , therefore the force is produced in both directions, leading to the use of a connecting rod.
