Abstract: A coolant control system of a vehicle includes first and second target flowrate modules, a target speed module, and a speed control module. The first target flowrate module determines a first target flowrate of coolant through an engine. The second target flowrate module, when a change in heat input to the engine is greater than a predetermined value, sets a second target flowrate to greater than the first target flowrate. The target speed module determines a target speed of an engine coolant pump based on the second target flowrate. The speed control module controls a speed of the engine coolant pump based on the target speed.

Abstract: A system and method of thermal management for an engine are provided. The system includes an engine, an electrical water pump, and a controller. The controller has a processor and tangible, non-transitory memory on which is recorded instructions. Executing the recorded instructions causes the processor to continuously monitor the temperature of the cylinder head and the temperature of the coolant. If the monitored temperatures of the cylinder head and the coolant are below predetermined thresholds, the processor executes a first control action, in which the pump remains off and the coolant remains stagnant. If either of the monitored temperatures of the cylinder head or coolant reaches the respective predetermined threshold, the controller initiates a second control action, which requires the controller to signal the pump to turn on and circulate coolant. The controller then determines the desired operating speed of the electrical water pump based on engine load.

Abstract: A technique for fuel system protection for an internal combustion engine includes introducing a directly injected fuel into a combustion chamber through a direct fuel injector, introducing a fumigated fuel upstream of an intake valve, selectively operating the internal combustion engine with at least one of the directly injected fuel and the fumigated fuel, determining a temperature of the direct fuel injector as a first function of engine operating parameters, and performing a temperature mitigation technique when the temperature rises above a first predetermined value such that the temperature is maintained below a second predetermined value.

Abstract translation: 提供了一种用于发动机的热管理系统和方法。 该系统包括发动机，电动水泵和控制器。 控制器具有处理器和有形的非暂时性存储器，在其上记录指令。 执行记录的指令会导致处理器连续监测气缸盖的温度和冷却液的温度。 如果气缸盖和冷却剂的监测温度低于预定阈值，则处理器执行第一控制动作，其中泵保持关闭并且冷却剂保持停滞。 如果气缸盖或冷却剂的监测温度中的任何一个达到相应的预定阈值，则控制器启动第二控制动作，其要求控制器发信号通知泵打开并循环冷却剂。 然后，控制器基于发动机负载确定电动水泵的期望运行速度。

Abstract: A method is disclosed for improving fuel economy in an internal combustion engine. The method may involve sensing a temperature of an engine block and determining a block thermal energy representing an ability of the block to reject heat. An open loop control scheme may be used together with the block thermal energy to predict if a coolant in the block is about to enter a boiling condition and, when this is about to occur, to open a block valve to permit a flow of coolant through the block. A closed loop control scheme may be used together with the sensed temperature of the block to determine if a coolant boiling condition is about to occur, and to control the block valve to permit a flow of coolant through the block which is just sufficient to prevent the onset of coolant boiling in the block.

Abstract: An engine control system is described. A cylinder control module selectively activates and deactivates intake and exhaust valves of a cylinder of an engine. A fuel control module disables fueling of the cylinder when the intake and exhaust valves of the cylinder are deactivated and, when the intake and exhaust valves of the cylinder are activated after being deactivated for at least one combustion cycle of the cylinder, adjusts fueling of the cylinder based on a predetermined reactivation fueling adjustment set for the cylinder.
