Abstract: An internal combustion engine includes an engine structure defining a cylinder having an intake port and an exhaust port. A piston is disposed in the cylinder and is drivingly connected to a crankshaft. A direct injection system injects fuel directly into the cylinder. A port fuel injection system injects fuel into the intake port. An oil temperature sensor and an engine speed sensor are in communication with a controller that controls the direct injection system and the port fuel injection system based on measured oil temperature and engine speed. In particular, the controller employs a control algorithm that alters the direct injection and port fuel injection split based on the measured oil temperature and engine speed. The maximum direct injection pressure reduction is limited by a maximum allowable port fuel injection duty cycle as determined by the controller.

Abstract: A turbocharger control system of a vehicle includes a trigger module that generates a trigger signal when a transmission of the vehicle is in one of (i) park and (ii) neutral. A wastegate target module, in response to the generation of the trigger signal, sets a target opening of a turbocharger wastegate to a predetermined opening and independently of a position of an accelerator pedal. The predetermined opening is greater than zero percent opening of the turbocharger wastegate. A wastegate actuator module actuates the turbocharger wastegate based on the target opening of the turbocharger wastegate.

Abstract: An exhaust brake torque system for a vehicle including an engine includes a controller configured to determine a current exhaust brake torque and a maximum exhaust brake torque. A display is configured to display at least one of the current exhaust brake torque, the maximum exhaust brake torque and a percentage corresponding to the current exhaust brake torque divided by the maximum exhaust brake torque. An engine speed sensor determines an engine speed of an engine. A pressure sensor is configured to sense turbine inlet pressure. The controller is configured to calculate the current exhaust brake torque and the maximum exhaust brake torque in response to the engine speed and the turbine inlet pressure.

Abstract: A charge air cooler includes a plurality of coolant passages spaced from one another and in communication with an inlet port and an outlet port. A plurality of air cooling fins are disposed between adjacent ones of the plurality of coolant passages, wherein the charge air cooler defines a first region wherein the air cooling fins have a first fin density and a second region wherein the air cooling fins have a second fin density different than the first fin density. The air cooling fins can also be provided with different louver shapes or designs in order to tailor, improve or unify the heat transfer rate at different regions of the charge air cooler.

Abstract: An internal combustion engine is disclosed which includes an improved crankcase drain back system. A set of drain flow diodes are disposed in each of the drain lines to direct fluid flow in a direction from the head portion to the crankcase. Likewise, a set of breather flow diodes are disposed in the breather lines to direct fluid flow in a second direction from the cylinder portion to the head portion. The flow diodes include a series of stacked flow diode elements which allow flow in one direction, while resisting flow in the opposite direction.

Abstract: A valve assembly includes a valve body defining a bore therein, a valve stem, a spring retainer, a valve spring, and a detent mechanism. The valve stem extends through the bore in the valve body and is adjustable between an open position and a closed position. The spring retainer is spaced apart from the valve body along a longitudinal axis of the valve stem and fixed relative to the valve body. The spring retainer defines a bore through which the valve stem extends. The valve spring is captured between the valve body and the spring retainer and is configured to apply a biasing force to the valve stem that biases the valve stem toward the closed position. The detent mechanism is configured to increase the biasing force applied to the valve stem when the valve stem is in the closed position or within a predetermined distance of the closed position.

Abstract: A system for controlling a fan of a vehicle engine. The system comprises: i) a fan configured to selectively cool the vehicle engine; and ii) an engine control module configured to: a) turn on the fan when the engine temperature exceeds a selected temperature threshold; b) determine when the vehicle engine is operating in an engine braking mode; and c) in response to the engine operating in the engine braking mode, turn on the fan when the engine temperature is below the selected temperature threshold. The engine control module turns the fan off as a means of hardware protection of the fan clutch even during engine braking modes.
