    摘要: An exhaust gas recirculation system for an internal combustion engine includes an exhaust manifold and at least one exhaust flow control valve located between the engine and the exhaust manifold. The exhaust flow control valve diverts a portion of the exhaust gas from each cycle of one cylinder and feeds that diverted portion to another of the cylinders through an exhaust gas recirculation passage, bypassing the exhaust manifold, whereby an exhaust stroke of a piston within the one cylinder serves to pump exhaust gas through the exhaust flow control valve in another cylinder.

    摘要: The present invention is an improved drive train which includes an engine having at least one power cylinder with a power piston mounted for reciprocating motion therein. The power piston is connected to a crank shaft in the usual manner for translation of the reciprocating motion of the power piston into rotation of the crankshaft, which in turn, is transmitted in the conventional manner to the drive wheels of the vehicle. Provision is made for the feed of fuel into a combustion chamber located within the power cylinder at one side of the power piston. Intake and exhaust valves, in fluid communication with the combustion chamber serve, respectively, to allow intake of air during an intake stroke of the power piston and exhaust of combustion products during an exhaust stroke of the power piston. A floating piston at least partially closes the combustion chamber opposite the power piston and is mounted for reciprocating motion relative to the combustion chamber. The reciprocating motion of the floating piston includes a pressure relieving stroke in which the floating piston moves away from the combustion chamber responsive to a predetermined pressure being produced within the combustion chamber by combustion, to reduce the peak combustion pressure.

    摘要: The invention is a combustion method for operation of a multiple cylinder internal combustion engine in a cycle including intake, compression, expansion and exhaust strokes. A first amount of fuel is introduced into each of the cylinders with introduction initiated earlier than 45.degree. before top dead center of a combustion stroke. An amount of air significantly in excess of that providing a stoichiometric amount of oxygen, typically 2-3 times stoichiometry, is also introduced into each of the cylinders to produce a first mixture upon introduction of the fuel, which mixture is ignited to produce a first combustion event. Subsequent to substantial completion of the first combustion event but prior to top dead center in the same compression stroke (or shortly after top dead center in the expansion stroke), a second amount of fuel is introduced into each of the cylinders without introduction of additional air. The second amount of fuel, products of combustion from the first combustion event and oxygen-depleted air form a second mixture which is ignited to produce a second combustion event. Utilizing two (or more) distinct combustion events in each "combustion cycle" significantly reduces the formation of NO.sub.x.

    摘要: A hydropneumatic powertrain includes a fluidic driver connected in parallel with first and second liquid tanks connected, respectively, with first and second gas vessels. The gas within each gas vessel is in fluid communication with the liquid within the corresponding liquid vessel. A prime mover drives a pump to pump liquid alternately into one of the two liquid tanks connected in parallel with the pump. Switch valving directs the discharge of the pump to either the first liquid tank or the second liquid tank, while the liquid tank not receiving liquid from the pump discharge is discharging its liquid, driven by expansion of gas within the corresponding gas vessel, to drive the fluidic driver which, in turn, drives the drive wheels of the vehicle. Each gas tank is equipped with a heater and a cooler whereby the gas vessel, in the compression portion of the cycle, is cooled while the other gas vessel is heated for expansion of the gas contained therein. Thus, the fluidic driver can be continuously driven by alternating discharges from the two liquid tanks.

    摘要: A novel, internal combustion engine includes a cylinder, a head closing one end of the cylinder and a piston slidably mounted in the cylinder for reciprocating motion, in the usual manner, which reciprocation is converted into rotary motion by, for example, a conventional crankshaft. The top surface of the piston, cylinder head and cylinder serve as walls defining a system chamber, with a pocket formed in one of the system chamber walls for receiving fuel and serving as a combustion chamber for localized combustion therein. In one disclosed embodiment, the cylinder is divided into two sections with thermal insulation, serving as a heat barrier, disposed between the two sections and the piston has a hollow interior containing one or more heat shields spanning the hollow interior. The method of operation involves injection of fuel into a restricted area within the chamber defined between the piston head, cylinder head and cylinder, e.g., the aforementioned pocket. Air and/or exhaust gas within the chamber surrounding the restricted area of localized combustion serves as thermal insulation, protecting the cylinder walls. Operation is suitably with a peak gas temperature of 900.degree.-1100.degree. C. and a peak gas pressure of 500-1000 psi. Air is introduced in an amount providing 4-5 times the stoichiometric amount of oxygen.

    摘要: Engine output speed is controlled for optimum efficiency by adjustment of input speed of a continuously variable transmission (CVT). Where power in excess of that provided by the engine is required, additional power is input to the drivetrain from a fluidic motor driven by fluid pressure stored in an accumulator. In driving conditions where the engine, operating at optimum efficiency, produces power in excess of that demanded by of the vehicle, the fluidic motor is reversed for operation as a pump and excess engine power is utilized to drive the pump and store energy in the accumulator in the form of fluid pressure. A CPU determines power output required of the engine as a sum of that indicated by a sensor which senses power demanded of the vehicle by a driver and an increment of power required to maintain the pressure of the accumulator above a threshold amount. An engine speed controller controls the rotary speed of the engine output, to produce the required total power output, by changing the input speed of the CVT. In order to maintain optimum engine efficiency, a memory associated with the CPU is stored with maps correlating values for optimum engine speed with values for engine output power and the optimum engine speed is read from the map by reference to the determined total requirement for engine output power. Optionally, the vehicle may include first and second engines with the second engine providing a power assist under driving conditions demanding power in excess of that available from the primary engine in combination with the fluidic motor. The invention also includes a method of operating the system in order to achieve the objective of optimum engine efficiency.

    摘要: The present invention is a water cut monitor which includes a settling tank in which a quantity of fluid from a producing well is accumulated. The fluid is removed as a stream of fluid after a predetermined interval from the accumulation of the fluid by the settling tank so as to allow the accumulated fluid to separate into three phases: free water, water-continuous and oil-continuous. The flow rate of the stream of fluid is measured and a corresponding flow rate signal is provided as well as a temperature signal corresponding to a sensed temperature of the stream of fluid. The water cut monitor includes a plurality of electrodes in contact with the fluid. Injection electronics connected to at least one of the electrodes provides an injection voltage and injection current to the fluid stream and also provides signals corresponding to the injection voltage and injection current. A voltage in the fluid stream is measured and a measurement signal provided. A computer determines the water cut of the petroleum stream in accordance with the temperature signal, the injection voltage and injection current signals, the electrical phase angle signal and the measured voltage signal.

    摘要: A method for operating a series hybrid vehicle is provided, in which an engine generates secondary power that is either stored or used as direct input energy by a secondary power source to provide motive power to the vehicle. Regenerative braking is used to convert kinetic energy of the vehicle into secondary energy, which is also stored. When the vehicle driver makes a power demand, the secondary power source is powered by secondary energy from an energy storage device, direct input energy generated by the engine, or both, depending on the amount of stored secondary energy in combination with vehicle speed. When in use, the power level at which the engine is operated is also determined on the basis of available stored energy and vehicle speed. At higher vehicle speeds, the amount of stored energy is allowed to be depleted in order to increase the available storage capacity for regenerative braking.
