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 ...
In an HCCI engine, however, the homogeneous mixture of fuel and air is compressed and combustion begins whenever sufficient pressure and temperature are reached. This means that no well-defined combustion initiator provides direct control. Engines must be designed so that ignition conditions occur at the desired timing.
By the late 1940s, the South African Railways (SAR) still had a comparatively large mileage of 45 pounds per yard (22 kilograms per metre) track. In South West Africa, where most of the locomotive fleet consisted of Classes 6, 7, GC and GCA, there were still hundreds of miles of 40 + 1 ⁄ 4 pounds per yard (20.0 kilograms per metre) track ...

The company was started by the Government of South Africa following the imposition of United Nations Security Council Resolution 418. The company was licensed in 1979 to manufacture Mercedes-Benz and Perkins diesel engines, [1] which were primarily destined for military vehicles such as the Ratel IFV, Buffel, Casspir and SAMIL Trucks. The ...
A common form of knock-down is a complete knock-down (CKD), which is a kit of entirely unassembled parts of a product. It is also a method of supplying parts to a market, particularly in shipping to foreign nations, and serves as a way of counting or pricing. [ 1 ]
