摘要： A premixed charge compression ignition engine, and a control system, is provided which effectively initiates combustion by compression ignition and maintains stable combustion while achieving extremely low nitrous oxide emissions, good overall efficiency and acceptable combustion noise and cylinder pressures. The present engine and control system effectively controls the combustion history, that is, the time at which combustion occurs, the rate of combustion, the duration of combustion and/or the completeness of combustion, by controlling the operation of certain control variables providing temperature control, pressure control, control of the mixture's autoignition properties and equivalence ratio control. The combustion control system provides active feedback control of the combustion event and includes a sensor, e.g. pressure sensor, for detecting an engine operating condition indicative of the combustion history, e.g. the start of combustion, and generating an associated engine operating condition signal. A processor receives the signal and generates control signals based on the engine operating condition signal for controlling various engine components to control the temperature, pressure, equivalence ratio and/or autoignition properties so as to variably control the combustion history of future combustion events to achieve stable, low emission combustion in each cylinder and combustion balancing between the cylinders.

摘要： A computer controlled auxiliary fuel tank system provides one or more additional fuel sources as either original equipment with new vehicles, or as an aftermarket addition to an older vehicle. The auxiliary system monitors and controls the on-board testing of each main fuel system, and their associated fuel displays, whether or not the vehicle includes a main fuel computer system. On-board testing is compliant with California Air Resources Board, On Board Diagnostics II, and with the Environmental Protection Agency On Board Diagnostics II) requirements. The auxiliary fuel system comprises an auxiliary fuel tank, having an auxiliary fuel pump, a sending unit, check valves, inlet and outlet fuel lines, a wiring harness, a computer module, an auxiliary emissions canister assembly, vehicle installation means, and LCD and LED display devices. Fuel levels in each tank are read, compared and balanced once every 4 seconds. Prior to each readings, the tank's senders are pulse-preconditioned so as to reduce the errors associated with fuel additive corrosion. In addition to the display of the gallons of fuel in each system, the vehicle's gas gauges are rescaled so as to indicate the percentage of total fuel on-board. In addition to warning of fuel quantity problems, the operator is made aware of the potential causes of such problems by being provided with a series of diagnostic trouble codes resulting from testing.

摘要： At least two separate fuels, having different volatility characteristics, are used to control the combustion phasing in a compression ignition engine. Desirably, the separate fuels are produced by distillation by which a parent fuel is separated into separate fractions having different reactivity. The provision multiple fuels by distillation and the control method embodying the present invention are particularly useful in controlling the combustion phasing of homogenous charge compression ignition combustion processes.

摘要： A reservoir in which fluid entering the reservoir is mixed with fluid already present in the reservoir is provided. The mixed fluid is then drawn from the reservoir in such a manner that the fluid drawn from the reservoir has a composition which closely approximates the average composition of the fluid in the reservoir. In this manner, the rate of composition change of fluid released from the reservoir is less than the rate of compositional change of fluid entering the reservoir.

摘要： The invention is directed to a system for supplying an internal combustion engine with fuel which includes the following functional components: a tank; a fuel pump; a metering device for metering fuel to the intake air; a feed line for conducting fuel from the fuel pump to the metering device; a reservoir which is so configured and mounted that fuel can be pumped therefrom to the metering device and which is not filled when tanking the tank and which can be again filled from the tank; and a control unit for driving the fuel pump and the metering device. The fuel pump is fixedly connected to the reservoir so that only fuel is pumped therefrom and a reservoir fill pump is provided which continuously maintains the reservoir filled as long as fuel is present in the tank. The system affords the advantage that even when, after tanking, fuel of a composition is present in the tank which is substantially different from the composition of the fuel present in the tank before tanking, the metering device first is supplied with fuel of the old composition and then the composition of the metered fuel only changes slowly. In this way, a continuous stable operation of the internal combustion engine is provided.
摘要翻译：本发明涉及一种用于向内燃机提供燃料的系统，其包括以下功能部件：罐; 燃油泵用于将燃料计量给进气的计量装置; 用于将燃料从燃料泵传导到计量装置的进料管线; 一种如此构造和安装的储存器，可以将燃料从其泵送到计量装置，并且当储存罐时不会填充，并且可以再次从罐中填充; 以及用于驱动燃料泵和计量装置的控制单元。燃料泵固定地连接到储存器，使得只有燃料被泵送并且提供储存器填充泵，其中只要存在于罐中的燃料就连续地保持储存器的填充。该系统的优点是，即使在油箱之后，组合物的燃料存在于罐中，其与在储存之前存在于罐中的燃料的组成基本上不同，首先向计量装置供应旧组合物的燃料然后计量燃料的组成只有缓慢变化。以这种方式，提供内燃机的连续稳定操作。

摘要： Fuel for a diesel engine is fed to the engine through a small float tank provided with a fuel heater. A cooling unit is employed to cool overheated fuel recycled from the engine. A temperature controlled valve is utilized to divert recycled fuel from the cooling unit through the float tank and back to the engine if the recycled fuel is sufficiently cool. The fuel heater, cooling unit and valve are adapted to optimize fuel temperature based on engine performance design.Water, propane, LPG, etc. also may be injected into the engine along with the diesel fuel to improve the combustion process and fuel economies.

摘要： An internal combustion engine system is described herein. The internal combustion engine system uses one or more fuels that may be hydrophilic. The system uses a water measuring sensor to determine the concentration of water in the hydrophilic fuel. To meet power demands, the system uses the measured water concentration to modify data stored in a fuel map. The fuel map provides a controller the pump speeds and mixing ratio of the fuels for a given power level. The system receives that data and modifies it based on the measured concentration of water.
