Abstract
A first pump serves to periodically inject fuel into a combustion chamber of an internal combustion engine at a first timing in terms of crankshaft rotation, i.e., crank angle. A second pump serves to periodically inject fuel into the combustion engine at the first timing and also at a second timing in terms of crank angle. The second timing precedes the first timing. The rate of fuel injection by the second pump at the first timing is inversely related to the rate of fuel injection by the second pump at the second timing.
