| 20080196693 | MULTIPLE INJECTION BLEND FOR DIRECT INJECTED ENGINES - A fuel injection system for a direct fuel injection engine is provided. The system includes an injection mode module that selects a fuel injection mode to be one of a single injection mode and a dual injection mode during engine operation and a fuel injection command module that commands fuel injection events based on a crankshaft position, the fuel injection mode and a fuel percentage blending schedule. | 08-21-2008 |
| 20080196694 | MULTIPLE INJECTION BLEND FOR DIRECT INJECTED ENGINES - A fuel injection system for a direct fuel injection engine includes an injection mode module. The injection mode module selects a fuel injection mode to be one of a single injection mode and a dual injection mode. A fuel injection command module transitions between the single and dual injection modes by varying the timing of fuel injection events relative to a crankshaft position. | 08-21-2008 |
| 20090038583 | MULTI-INJECTION COMBUSTION CYCLE SYSTEMS FOR SIDI ENGINES - The fuel injection system includes a fuel injector that injects fuel directly into a combustion chamber of a cylinder of an engine. The control module initiates multiple fuel injections in a combustion chamber during a combustion cycle of the cylinder via the fuel injector. | 02-12-2009 |
| 20090084347 | SYSTEM AND METHOD FOR INJECTING FUEL INTO A DIRECT INJECTION ENGINE - A method for controlling the operation of at least one fuel injector in a four stroke internal combustion engine is provided. The method includes the steps of initiating fuel injection into a combustion chamber during an expansion stroke of the engine, injecting fuel into the combustion chamber during an exhaust stroke of the engine, injecting fuel into the combustion chamber during an intake stroke of the engine, and terminating fuel injection into the combustion chamber during a compression stroke of the engine. | 04-02-2009 |
| 20090216428 | LATE INTAKE VALVE CLOSING TO IMPROVE COLD STARTABILITY FOR SPARK-IGNITION DIRECT-INJECTION (SIDI) ENGINES - An engine control system includes a cam phaser that introduces a cam phase angle θ between a camshaft intake lobe and an associated crankshaft. An engine control module communicates with the cam phaser to introduce the cam phase angle θ while an engine is being started. The cam phase angle θ is selected such that the camshaft intake lobe opens an intake valve during at least a portion of a compression stroke of a cylinder that is associated with the camshaft intake lobe. | 08-27-2009 |
| 20100147240 | METHOD OF STARTING SPARK-IGNITION DIRECT INJECTION (SIDI) ENGINES - A cold start control module for a direct injection engine includes a fuel flow determination module and a cylinder activation/deactivation module. The fuel flow determination module determines a requested fuel flow. The cylinder activation/deactivation module deactivates at least one of cylinders when the requested fuel flow exceeds a maximum fuel flow of the fuel pump during cold start. | 06-17-2010 |
| 20100154739 | DEACTIVATION OF HIGH PRESSURE PUMP FOR NOISE CONTROL - An engine control system comprises an engine speed monitoring module and a pump control module. The engine speed monitoring module compares an engine speed and a predetermined threshold. The pump control module deactivates a pressure pump based on said comparison. | 06-24-2010 |
| 20100180863 | ASYNCHRONOUS CONTROL OF HIGH-PRESSURE PUMP FOR DIRECT INJECTION ENGINES - An engine control system includes a starting module, a position module, and a deactivation module. The starting module determines when a crankshaft starts to rotate and activates a control valve of a fuel pump when the crankshaft starts to rotate. The position module determines a position of the crankshaft and determines a position of a camshaft based on the position of the crankshaft. The camshaft drives the fuel pump. The deactivation module deactivates the control valve when the position module determines the position of the camshaft. | 07-22-2010 |
| 20100280742 | CONTROL SYSTEM AND METHOD FOR CONTROLLING AN ENGINE IN RESPONSE TO DETECTING AN OUT OF RANGE PRESSURE SIGNAL - A method and control module for operating an engine that includes a pressure range determination module that determines a pressure value for a pressure sensor in a fuel rail is out of range. A fuel rail pressure estimate module that determines a predicted pressure value. An engine control module that operates the engine using the predicted pressure value. | 11-04-2010 |
| 20100292909 | INJECTION ADVANCEMENT FOR PISTON COOLING IN SPARK IGNITION DIRECT INJECTION ENGINES - An engine system comprises a temperature determination module, a temperature comparison module, and a fuel injection control module. The temperature determination module determines an engine temperature. The temperature comparison module compares the engine temperature and a temperature threshold. The fuel injection control module adjusts a timing of fuel injection from a first range of an intake stroke to a second range of the intake stroke based on the comparison. The first range and the second range do not overlap. | 11-18-2010 |
