System and method of speed-based downspeed coasting management
A velocity profile can be used in conjunction with vehicle operating condition data to determine a gear shift schedule that mitigates the amount of service brake effort required to slow a vehicle by making optimal use of engine speed, friction and engine brakes. The gear shift point drives the engine to a higher operating speed and greater frictional torque, slowing the vehicle, which can then coast to a desired speed. The gear shift point can be timed to minimize fuel consumption during the maneuver. Thus, a vehicle downshift event is created based on the transmission gear recommendation. The benefit is increased freight efficiency in transporting cargo from source to destination by minimizing fuel consumption and maintaining drivability.

More particularly, a Rankine cycle WHR system and method is described, including an arrangement to improve the precision of EGR cooling for engine efficiency improvement and thermal management.
A waste heat recovery system connects a working fluid into passages formed within an internal combustion engine. The fluid passages transport the working fluid to high temperature areas of the engine, raising the temperature of the working fluid near the phase change point or above the phase change point. The heated working fluid drives an energy conversion portion located downstream from the engine. The heat absorbed by the working fluid decreases the load on an engine cooling system as well as driving an energy conversion portion, improving fuel efficiency.
An internal combustion engine includes a cooling fluid circuit and a pumping circuit. The pumping circuit drives an ejector pump located along the cooling fluid circuit, enabling a reduced parasitic load on the engine from pumping cooling fluid through the cooling fluid circuit.
An improved cooling fluid passage configuration provides for uniformity of cooling about the entire periphery of a cylinder liner of an internal combustion engine in addition to improved cooling by increasing the flow in an upper water jacket of a split water jacket design. The cooling fluid passage configuration also provides a reduced pressure drop between a cylinder liner cooling fluid inlet and a cylinder head cooling fluid outlet when compared to conventional designs with a single head feed line, permitting use of a smaller cooling fluid pump and leading to increased efficiency of the engine.

Systems and methods of vehicle freight/load distribution are provided to assist in determining optimal freight distribution. Although it is standard practice to fill each vehicle to its maximum limit, due to the non-linear nature of engine fueling maps (that is, fueling maps vary non-linearly as a function of torque and speed), the optimal distribution may not be obtained by the standard practice. Finding a solution for the optimal freight distribution may also need to account for the cost of fueling and operator costs, particularly if the situation involves multiple vehicles not filled to capacity. The benefit is increased freight efficiency in transporting cargo from source to destination amongst a fleet of vehicles.

Piezoelectric fuel injector system, method for estimating timing characteristics of a fuel injection event
This disclosure provides a fuel injector system and method in which the timing of events in during period of fuel injection of a piezoelectric-actuated fuel injector are estimated based on sensed forces within the injector. The force sensor is positioned between a piezoelectric actuator and a hydraulic link assembly mechanically coupled with the piezoelectric actuator, and the force sensor operable to output a signal corresponding to forces between the piezoelectric actuator and the hydraulic link assembly. From information contained in the sensor output signal, timing in the injection period of at least one fueling characteristic based can be estimated to allow for adjusting fuel injector characteristics to compensate for variations affecting fuel injection, such as manufacturing tolerances, environmental conditions, and deterioration/wear.
The disclosure provides a waste heat recovery system and method in which pressure in a Rankine cycle (RC) system of the WHR system is regulated by diverting working fluid from entering an inlet of an energy conversion device of the RC system. In the system, an inlet of a controllable bypass valve is fluidly coupled to a working fluid path upstream of an energy conversion device of the RC system, and an outlet of the bypass valve is fluidly coupled to the working fluid path upstream of the condenser of the RC system such that working fluid passing through the bypass valve bypasses the energy conversion device and increases the pressure in a condenser. A controller determines the temperature and pressure of the working fluid and controls the bypass valve to regulate pressure in the condenser.

An early intake valve closing (EIVC) and variable valve timing (VVT) assembly and method are provided for an internal combustion engine. The method includes operating an intake valve to open and close an intake port and allow intake gas to enter a cylinder of the internal combustion engine containing a piston, where the timing of the closing of the intake valve occurs at or before bottom dead center (BDC) of the compression stroke of the piston. The method further includes selectively extending duration of the opening of the intake port by an amount that delays closing timing of the intake valve until after BDC of the piston compression stroke. An assembly for EIVC and VVT includes a cylinder head including an intake valve and intake port and a rotatably mounted camshaft including an intake lobe operatively connected to the intake valve to periodically move the valve into the first and second positions. The intake lobe is shaped such that the timing of the closing position occurs at or before BDC of a compression stroke of the piston. The assembly further includes a selectively activatable VVT assembly having an actuator that operatively engages the intake valve before the intake valve reaches the closed position to extend duration of the intake valve opening until after BDC of the piston compression stroke.
