Abstract
In the operation of a diesel engine, a mixture of air and fuel is flowed into each cylinder during the intake stroke when air alone normally would be flowed in. However, the mixture is lean so it does not ignite as the mixture is compressed and heated. Sufficient additional fuel is injected into the cylinder near the top of the compression stroke to increase the amount of fuel so the hot mixture ignites. As a result, most of the air and fuel has intimately mixed prior to ignition.
