Abstract: A water cooled, compression ignition engine (1) running on a low cetane fuel comprising a turbocharger (7), an air to air aftercooler (15) and an intake air manifold (3) for supplying compressed combustion air to the engine (1), a heated bypass heat exchanger (19) using heated water from the engine (1) and disposed to bypass the aftercooler (15), and a modulating bypass valve (21) adapted to respond to intake manifold pressure to control the amount of combustin air bypassing the aftercooler (15) and being heated in the bypass heat exchanger (19) to eliminate misfiring and poor combustion during startup and when operating at low loads and promoting better fuel economy, performance and emissions as the load on the engine increases.

Abstract: A method of initially operating an internal combustion engine (10) including operating the engine (10) in a start-up mode is provided. The start-up mode includes injecting at least two fuel pre-shots wherein a first of the fuel pre-shots is smaller in quantity than a last of the fuel pre-shots. An engine (10) is provided including an electronic controller (40) with a computer readable medium having a control algorithm recorded thereon, the control algorithm including means for commanding injection of a main fuel shot and at least two fuel pre-shots wherein a first of the fuel pre-shots is smaller in quantity than a last of the fuel pre-shots.

Abstract: A system and method for the identification of the fuel used in an electronically controlled internal combustion engine that may utilize an advanced fuel such as a fuel emulsion is provided. Where an unauthorized fuel is determined to be used in the engine, the electronic control module disables the engine by limiting fuel flow to the injectors.
