<p>The engine, particularly a gasoline engine 100, is connected with an EGR device 24 for reducing NOx emissions. The auxiliary water-supply system comprises a large water tank 12 feeding a small water tank 14 which supplies water to the EGR device via a valve 18, controlled by control unit 50, and a manual regulator 20. The control unit receives signals representing large tank water level, engine speed and engine cooling water temperature. Water and exhaust gases are fed into the gasoline engine simultaneously so as to increase the combustion efficiency of the engine, to reduce the density of pollution waste exhausted, and to increase the serviceable life of the gasoline engine. Also disclosed is an ignition method in which a number of auxiliary high voltage pulses are produced between consecutive main pulses to further improve combustion efficiency.</p> |
