A new complex of engine test cells being used by a British car manufacturers to develop cleaner, more fuel-efficient engines of the future is to be linked to computers both in Britain and the United States. The new system, known as “engine mapping,” records up to 2500 different readings during a single test. This gives a complete picture of what happens in an engine second by second. The entire test is controlled by the computer so that at each step the engine is fed automatically with a wide range of fuel-air mixtures, varying proportions of recirculated exhaust gas, and extra air injected into the exhaust manifold. The computer also controls ignition timing, scanning a range of settings at each stage. Before the new system was installed there were about 40 data collection points in a car engine—now there are 2500.
