  • Patent number: 10280877
    Abstract: A method and apparatus for the oxy-combustion of fuel in an internal combustion engine (ICE) used to power a vehicle includes one or more air separation devices that separate oxygen from the atmospheric air to mix with the fuel and return the nitrogen to the atmosphere and converts the free energy available in the form of waste heat from the engine exhaust gas stream and coolant system on board the vehicle into electrical and/or mechanical energy, which energy is used to separate oxygen from air to eliminate or significantly reduce the volume of nitrogen entering the ICE's combustion chamber, and thereby reduce NOx pollutants released into the atmosphere and increase the concentration of CO2 in the engine exhaust stream for capture using an integrated system to compress and increase the density of the captured CO2 for temporary on-board storage until it is discharged at a recovery station, e.g., during vehicle refueling.

    Abstract: A two-stroke engine has an intake arrangement including a carburetor. An intake channel divides into a mixture channel and an air channel. An intermediate flange is mounted between the carburetor and the cylinder. This flange has a carburetor connecting surface, which faces toward the carburetor, and a cylinder connecting surface which faces toward the cylinder. Referred to the flow direction in the intake channel, the air channel divides upstream of the cylinder connecting surface into two branches. The first branch has a first longitudinal center axis and the second branch has a second longitudinal center axis. The intersect points of the center axes with the connecting surfaces are mutually connected via an imaginary connecting line in the carburetor connecting surface or the cylinder connecting surface. The two connecting lines conjointly define an angle ? in the carburetor connecting surface with this angle being greater than 0°.

  • Patent number: 8744733
    Abstract: An object of this invention is to promptly detect a crank angle based on in-cylinder pressures and easily compensate for a detection error by processing that has a low computational load. An ECU 50 calculates an in-cylinder pressure ratio (Pn+1/Pn) based on in-cylinder pressures Pn and Pn+1 at two crank angles separated by a predetermined angle ??. The ECU 50 includes map data that represents relations between volume ratio parameters (Vn?/Vn+1?) calculated using in-cylinder volumes Vn and Vn+1 at the crank angles, and the crank angles. Therefore, when cranking, a crank angle can be detected based on the in-cylinder pressure ratio and the map data earlier than a conventional cylinder discrimination operation. Gains included in the in-cylinder pressures Pn and Pn+1 can be removed by dividing the two pressures, and exponential operations and the like can be eliminated by using the map data to thus suppress the computational load.

  • Patent number: 8731802
    Abstract: A method for compensating for thermal transient conditions of an engine that can cause valve growth or contraction is disclosed. In one example, the method provides cylinder air amount compensation during non-blow-through and blow-through conditions. The approach may improve cylinder air amount estimates, thereby improving engine emissions.

  • Patent number: 8706383
    Abstract: A control system includes an engine control module that generates fuel injector command signals for fuel injectors of an engine and engine parameter signals that indicate operating characteristics of the engine. A fuel injector control module communicates with the engine control module via a network. The engine control module transmits the engine parameter signals to the fuel injector control module via the network. The fuel injector control module generates compensated fuel injector signals based on the fuel injector command signals and the engine parameter signals. The engine control module may generate fuel injector command signals for a gaseous fuel mode based on signals received from the fuel injector control module.

  • Patent number: 8683976
    Abstract: Methods and systems are provided for identifying and indicating degradation of an engine cylinder spark plug. In response to a cylinder misfire event during selected engine operating conditions, followed by an occurrence of a threshold number and/or rate of pre-ignition events in the same cylinder, a controller may determine that the spark plug is degraded. The controller may limit combustion in the cylinder in response to the degradation. Additionally, cylinder pre-ignition mitigating steps may be taken.

  • Patent number: 8682566
    Abstract: Various methods are described for controlling engine operation for an engine having a turbocharger and direction injection. One example method includes performing at least a first and second injection during a cylinder cycle, the first injection generating a lean combustion and the second injection injected after combustion such that it exits the cylinder unburned into the exhaust upstream of a turbine of the turbocharger; and adjusting at least the first injection based on engine speed, where the at least first and second injection are performed responsive to turbocharger speed.

  • Publication number: 20140076271
    Abstract: An internal combustion engine is provided. The engine comprises at least one combustion chamber. The engine is suitable for various types of fuel. The engine, depending on fuel type, may have at least one spark plug. The engine uses an external source of compressed oxidant, such as air, which is delivered from a compressor and/or pressurized storage tank. Compressed oxidant, such as air, is delivered directly into the combustion chamber. Fuel is delivered directly into the combustion chamber. Oxidant and fuel mixture is ignited either by means of a spark plug, laser ignition, or by other means, or ignites spontaneously, depending on fuel type and pressure in the combustion chamber. The engine may comprise at least one cylinder, or may be of rotary or other type. A hybrid vehicle based on such an engine is provided. An automatic parking system for such a vehicle is provided.

  • Publication number: 20140053810
    Abstract: A cylinder for an internal combustion engine having co-annular dual pistons. The cylinder has a main cylinder having a main cylinder wall and a cylinder head, a first or outer piston having an annular crown, an inner cylinder wall that defines an inner cylinder, and an annular outer sidewall extending from the periphery of the crown, an inner piston having a crown, and an annular inner sidewall extending from the periphery of the crown. A solenoid-actuated pin selectively secures the outer piston with the main cylinder during a portion of each cylinder cycle. The inner piston reciprocates within the inner cylinder during both the air inlet and compression strokes, while the outer piston reciprocates within the main cylinder only during the power stroke and the exhaust stroke, to increase the piston crown surface area exposed to the combustion gases to maximize the power and efficiency.

  • Patent number: 8613272
    Abstract: Conventional spark-ignited gas engines with a mechanically controlled fuel feed valve have several disadvantages in terms of operation, expensive control, irregular combustion or unstable and unreliable operation, which in turn can lead to operational and mechanical problems. In order to eliminate these disadvantages it is suggested, according to the invention, that a controlled valve is installed in the fuel line upstream of the fuel feed valve so that in the fuel line between fuel feed valve and controlled valve a defined intermediate volume is created and gaseous fuel is fed via the controlled valve into the intermediate volume.
