    摘要： An engine management system and method may include a control system and method for controlling an internal combustion engine. The internal combustion engine may be a direct-injection engine using a Sonex Controlled Auto-Ignition (“SCAI”) combustion path. The control system and method may utilize fuel injection pressure, timing of start and end of injection, management of turbo airflow, fuel supplied, and other factors to provide reduced emissions and improved performance.

    摘要： A piston for a reciprocating piston internal combustion engine is provided with a reaction chamber (44, 144) communicating with a recessed area (42, 142) of the piston through a restricted continuous slot orifice (46, 146) that is configured to create a choked fluid flow condition between the combustion chamber (30, 130) and the reaction chamber at all engine operating speeds. Fuel is supplied to the reaction chamber and undergoes a controlled, cold frame reaction process while in intimate contact with the crown portion (54) of the piston (14). The reaction produces fuel radicals in sufficient quantity to seed subsequent fuel charges to properly condition the charge for predetermined desired ignition and combustion characteristics. The choking orifice (46, 146) ensures that outward flow of radicals from the reaction chamber is controlled to the extent that they will be maintained in the combustion chamber following an exhaust event of the combustion cycle so they will be available during a subsequent compression stroke of the piston for seeding the subsequent charge. The radical population in the subsequent charge conditions the charge to obtain dependable and predictable ignition in a compression ignition engine as well as knock free combustion at relatively lean air to fuel ratios in a spark ignited engine.

    摘要： An adaptive charge mixture control for an internal combustion engine includes four input signals supplied to an OR gate to generate a net "go rich" signal supplied to a servo motor controlling an air/fuel charge mixture control valve for an internal combustion engine. The servo is also supplied with a "go lean" fixed signal tending to lean out the air/fuel mixture. The four "go rich" signals include a first signal derived from a comparison of engine speed with a predetermined minimum (i.e., idle) level; a second signal derived from comparing throttle positions with a preset minimum throttle position; a third signal derived from comparing engine deceleration rate with a preset engine deceleration rate; and a fourth signal derived from a measurement of engine instantaneous power output.

    摘要： An improved apparatus and technique for providing increased efficiency and relatively pollutant free operation of internal combustion engines. An internal combustion engine's gas cycle is refined by forming a secondary balancing non-combusting chamber within the main combustion chamber of each cylinder. The balancing chamber is constructed on a piston surface or within the piston body and operates as a pressure exchange or wave generator during the gas cycle of the internal combustion engine. This permits control of the pressure and temperature within the combustion chamber during the liberation of heat caused by combustion of fuel and air on the power cycle of the engine. The apparatus, the balancing chamber, controls pressure and temperature during this cycle by introducing expansion and compression waves, in the combustion zone during burning of the fuel, that follow one another in sequence without interruption throughout the entire power cycle of each cylinder of the internal combustion engine. The oscillating pressure exchange between the expansion and the compression waves within the combustion chamber during burning of the fuel in each cylinder supplies clean air to support more complete combustion and provides lower combustion temperatures and pressures during operating of the internal combustion engine, thus decreasing the formation of engine exhaust pollutants.
