A fuel management control method for a hybrid electric vehicle drive having an internal combustion engine and an electric motor arranged in parallel such that both can propel the vehicle; the system including an electric motor driven fuel pump and a programmable microprocessor; and wherein the method further includes monitoring vehicle speed and sensing braking pressure and directing signals of both vehicle speed and braking to the microprocessor and processing such inputs in accordance with an aggressive fuel management program including shut-off of fuel flow to the gas engine in response to vehicle braking at vehicle speeds above a predetermined maximum hysteresis speed and maintaining the fuel shut off during vehicle coasting above a predetermined speed while controlling the electric motor to provide regenerative braking or vehicle start during such fuel shut off modes of operation.
摘要:
A method of controlling engine crankshaft motion in a hybrid electric drive system having an internal combustion engine and a motor-generator operatively connected to a crankshaft of the engine is disclosed. The steps include monitoring the crankshaft position, forecasting a crankshaft stall position; comparing the forecast stall position with a target range; and if the forecast crankshaft stall position is outside the target range, operating the motor-generator to modify the forecast stall position to be within the target range. These steps properly position the crankshaft for re-initiating engine start-up. The method further includes the steps of calculating an effective lube interval time once the crankshaft speed is zero; comparing the effective lube interval time to a critical time; and if the effective lube interval time is greater than the critical time, pulsing the motor-generator to rock the crankshaft for a pulse time to redistribute a lubricant film.

A first clutch circuit for an automatic transmission in a hybrid drive vehicle comprises an apply line extending from a manual valve to a clutch, with a check ball disposed in the apply line operable to move out of the apply line upon upstream fluid pressure, and an exhaust line extending from the apply line, downstream of the check ball, to an exhaust valve. A driver-triggered valve actuating means operates to close the exhaust valve when the driver selects drive with a driver shift lever and to open the exhaust valve when the driver shifts out of drive thereby releasing the clutch.

High throughput compound profiling systems, and related devices and sub-systems that can be used to perform various compound profiling processes are provided. These systems typically include work perimeters that are organized for optimum efficiency and processing accuracy. Further, these systems are readily adaptable for performing a wide array of assays, as many different system components are easily incorporated or interchangeable in a particular system. System components that are provided by the invention include cell culture dissociators, which can be used, e.g., to effect cell wetting, dissociation, and/or agitation applications. In some embodiments, these cell culture dissociators are included as components of automated cell culture passaging stations. Dispensing devices that permit on-the-fly fluid temperature regulation are also provided. In addition, various compound profiling methods, cell dissociation methods, uniform cell concentration dispensing methods, among other processes, are also provided.

A method is provided which comprises: performing a plurality of fermentations, each fermentation in a different sample vessel; and performing a further processing step on the plurality of fermented samples where the sample is retained in the same sample vessel as the fermentation during the processing step.
摘要:
A fermentation apparatus is constructed to produce a known and repeatable amount of unpoisoned fermentation product using multiple fermentation vessels. To facilitate further processing compatible with other product processing steps, the fermentation apparatus has an array of sample vessels arranged in a container frame. The container frame is configured to hold the sample vessels during fermentation and to transport the vessel array to or from another processing station. Corresponding to the number of sample vessels in the sample vessel array, a cannula array is configured such that each cannula may be placed inside a sample vessel. The cannula array is attached to a gas distributor that delivers oxygen and/or one or more other gases from a gas source through the cannula into the sample vessel. Because the fermentation volume for each individual sample vessel is smaller than a bulk fermentation apparatus, the fermentation product yields are more predictable and cell growth rates may be more effectively optimized.
摘要:
An electro-hydraulic control system for an automatic transmission comprises a manual selector valve for operator direction of line pressure fluid to a drive passage when drive is selected or to a reverse passage when reverse is selected. A drive/reverse passage connects the drive passage and the reverse passage. A first check ball is disposed between the drive passage and the drive/reverse passage and a second check ball is disposed between the reverse passage and the drive/reverse passage wherein the check balls operate to pressurize the drive/reverse passage when either drive or reverse is selected. The system further includes six fluid operated selectively engageable friction devices, three friction device actuators each associated with one of the six friction devices, in parallel relation and electronically actuated to direct fluid from the drive passage to the respective friction device, and a two-friction device actuator operative to direct fluid from the drive/reverse passage to one of two friction devices. Three pressure-operated feed protection valves are disposed intermediate of two of the actuators and their two friction devices, which operate to prevent flow to the two downstream friction devices.
