摘要： A method and a system of igniting an internal combustion engine is described. According to the invention, at least one combustion chamber is provided that is arranged to receive at least two spark plugs having their electrodes in proximity to each other. In a work cycle of the engine are providing simultaneously by a pulsed ignition system at least two high voltage pulses of opposite polarity to the spark plugs, which brings the spark plugs to ignite a spark between their electrodes. In a subsequent work cycle of the engine the polarity of said high voltage pulses are reversed the spark plugs are brought to ignite a spark between their electrodes with the reversed polarity the pulses. The internal combustion engine is then run by igniting sparks between the spark plug electrodes and toggling the polarities of said electrodes according to a predetermined timing pattern.

摘要： A method, system, and apparatus relating to operating an internal combustion engine include steps or features for determining a performance threshold of a particulate filter disposed in an exhaust gas flow of the engine having a set time interval between regeneration events of the particulate filter; determining a rate at which the particulate filter is reaching the performance threshold; and controlling an exhaust gas characteristic to control the rate so that the performance threshold is reached at or just before an end of the time interval. In an embodiment, there are steps or features for interpreting a filter condition of the particulate filter; determining a particulate matter load rate of the filter as a function of the condition; determining a limit of an exhaust gas characteristic based on the load rate; and controlling engine operation to control the exhaust gas characteristic to satisfy the limit.

摘要： The subject of the invention is an internal combustion piston engine and a method of its operation combining efficient features of two-cycle engines (two-stroke engines) and four-cycle engines (four-stroke engines). Furthermore, this engine operates with one or more explosions at each revolution of a crankshaft ensuring the intake, compression, explosion and exhaust strokes in the working space (18) during one revolution of the crankshaft. The engine comprises a compression space (9B) connected to the intake manifold (9A) using a one-way valve (8) and connected to the working space (18) using the intake valve (5A). After explosion of a compressed fuel-air mixture in the area of the top dead centre of the piston and rotation of the crankshaft from it at a given angle the intake valve (5 A) is opened, and the fuel-air mixture is exploded, wherein the fuel-air mixture is in the compression space (9B) providing further energy to the piston (11).

摘要： A dual crankshaft internal combustion engine having two rotating offset crankshafts respectively attached to connecting rods. Each of the connecting rods, in turn, are pivotally attached to piston rods, which are located an equidistance between the crankshafts. The piston rods are attached to a piston reciprocally disposed in a cylinder. The crankshafts are aligned in parallel and are geared together, either directly or indirectly, thus causing the crankshafts to rotate in the same or opposite directions, depending upon the linkage gear configuration. The dual crankshaft internal combustion engine utilizes leverage from the wedge-effect of the offset crankshafts to provide increased torque, power duration and fuel efficiency.
