Abstract: A natural gas fueled vehicle, includes a natural gas fueled Internal Combustion Engine (ICE) to provide motive power to the vehicle. A pressurizable tank is disposed on the vehicle to contain a natural gas. A natural gas adsorbent is disposed in the tank. A fuel supply tube is to convey the natural gas to the ICE. A scroll compressor is on the vehicle to receive the natural gas from the tank and to deliver a first mixture of compressed natural gas and an oil to a gas and oil separator. The gas and oil separator is to receive the first mixture of the compressed natural gas and the oil from the scroll compressor and to separate the oil from the compressed natural gas and to deliver the compressed natural gas to the fuel supply tube substantially free from the oil.

Abstract: A turbocharger includes an annular bypass volute to allow exhaust gas to bypass the turbine wheel. An annular bypass valve is disposed in the bypass volute. The bypass valve comprises a fixed annular valve seat and a rotary annular valve member arranged coaxially with the valve seat. The valve member is disposed against the valve seat and is rotatable about the axis for selectively varying a degree of alignment between respective orifices in the valve seat and valve member. The valve member is rotatably driven by a rotary actuator and drive linkage that rotates about an axis parallel to and offset from the axis about which the valve member rotates.

Abstract: A method for determining a position of a lock element of an injection valve for an internal combustion engine includes moving the lock element in the direction of a locked position in a closing movement in order to lock the injection valve, subsequently measuring a closure time at which the lock element arrives in the locked position, determining a time difference between the closure time and a preceding starting time of the closing movement, and determining, based on the time difference, a position which the lock element has assumed at the starting time of the closing movement.

Abstract: A vehicle, including watercraft and personal watercraft, includes a hull, an engine system and a propulsion system. The engine system comprises an internal combustion engine and an air intake for receiving air to be mixed with fuel supplied to the engine. The propulsion system connects to the engine and propels the watercraft along a surface of a body of water using power from the engine. The watercraft can include a quick connect air/water separator, or air box. A fuel system is provided that has a fuel supply line and a fuel return line which are connected with a bypass line. For evacuating fuel from the supply line and the return line, the bypass line contains a valve which can be actuated to allow fuel to flow into the fuel reservoir. A lubrication system is provided that includes a filler neck comprising an oil/air separator which allows a mixture of oil and air to be separated and the oil to be returned to the oil reservoir.

Abstract: A fuel injection apparatus in which the duration of fuel supply of at least two pump pistons of a fuel injection pump is determined by the closing duration of an electrically actuated overflow valve. The overflow conduits of at least two adjacent pump work chambers are interconnected, and the return flow of fuel from these overflow conduits to a chamber of lower pressure is controllable by the control element of the overflow valve which is common to these overflow conduits. The overflow conduits are each provided with one barrier valve, by means of which the at least one pump work chamber not under injection pressure at a given time can be blocked off from the pump work chamber which is placed under injection pressure at that time.

Abstract: Disclosed is a system for maintaining the desired idling speed of an internal combustion engine. In its simplest form the system utilizes a speed biasing mechanism to regulate a source of fluid pressure supplied to a fluid pressure regulator to provide a first fluid pressure control signal therefrom that is proportional to changes in the rotational speed of the engine and is utilized to move a force member of an actuator device in such a manner as to maintain the engine idling speed. Alternative embodiments include combining the first fluid pressure signal in an integrator in the manner described with one or more additional fluid pressure signals derived from changes in other engine operating conditions to provide a control signal therefrom that is able to regulate a source of fluid pressure supplied to a regulator to provide the fluid pressure control signal for maintaining the engine idling speed.

Abstract: An emergency shutdown device for an internal combustion engine, especially a fuel-injected diesel engine. In addition to shutting off the flow of fuel to the engine, the device "suspends" fuel within the engine fuel supply system to prevent it from passing into the engine combustion chambers. The device provides a controllable vacuum means which, by preventing fuel passage into the fuel injector pumps, quickly "starves" the engine of its fuel supply.

Abstract: A speed control system for controlling a vehicle's speed operates by means of limiting fuel flow to the engine of the vehicle at and above, a predetermined speed. the system comprises fuel line means to the engine, a fuel pump feeding the fuel line means, a fuel bypass from the fuel line means which is normally closed and a monitoring means for monitoring the speed of the vehicle and for opening the fuel bypass when the vehicle speed reaches or exceeds the preset speed to bypass the fuel from the fuel line means and limit fuel flow to the engine. The fuel bypass is provided with automatic pressure regulating valve means adjusted to maintain the amount of fuel flow in the fuel line means at all times for engine idling.
