Abstract: A gas substitution system for a dual fuel diesel engine which monitors load and RPM and the operational state of the engine and vehicle including throttle displacement, cruise control, idle, wheel and engine braking, manual control. Data is collected to establish parameters such as fuel consumption and exhaust emissions for load/RPM pair values and using these to create a table of optimum gas substitution values at each load RPM pair within the range of operational states within which substitution is viable. The system is applicable to: constant engine speed stationary applications (gensets); variable engine speed applications, including mobile plant; automative applications with no existing engine management system; automative applications with a basic existing engine management system; automative applications with an advanced existing engine management system.

Abstract: An air-compressing, self-igniting combustion engine for liquid fuels, in an arrangement that includes a combustion chamber depression in a piston for receiving injected fuel predominantly in the vicinity of the wall thereof and for receiving rotating combustion air at the time of fuel injection. Oxygen-containing fuel that is reluctant to ignite is injected through a first injection device into the combustion chamber depression; through a second injection device there is injected fuel that is willing to ignite, for instance oil fuel, gas oil or Diesel fuel, for initiating and/or maintaining the fuel combustion in the combustion chamber depression. Furthermore, the injection times of the fuel that is willing to ignite and the oxygen-containing fuel that is reluctant to ignite overlap each other. The first and second injection nozzles each are arranged with an injection pump and are rigidly coupled and have a common injection adjuster. Both injection nozzles are combined in a single-nozzle body. One injection nozzle is embodied as a two-hole nozzle which is inclined at an acute angle in the twist direction, the fuel streams of which however form such a small differential angle with respect to each other that the droplets of the oxygen-containing fuel that is unwilling to ignite in essence form a common droplet veil or mist. The injection nozzles are so directed that a separate droplet veil or mist results for both fuels.

Abstract: A dual fuel system for a diesel engine (12)includes a liquid (diesel) fuel injection system (14) controlled by an engine electronic control unit (ECU) and a source (25, 26, 28, 30) of gaseous fuel such as natural gas. A metering valve (30) and a mixer (32) controls introduction of gaseous fuel from the natural gas fuel source (25, 26, 28, 30) into conbustion air for the engine (12). An electronic governor (36) controls the metering valve and a link controller (40) coordinates operation of the ECU (34) and the governor (36). Preferably, a regulator regulates the natural gas pressure supplied to the metering valve. A shut-off valve (26) controls communication of natural gas between the source and the regulator (28). The link controller (40) also controls the shut-off valve (26) as a function of sensed conditions.
