ABSTRACT:
An internal combustion engine in which a compact ring type boiler pack is installed around each cylinder under the cylinder head. Water is pumped through each boiler at a rate proportional to the cylinder temperature, to maintain a proper cooling and steam injection balance, the generated steam being injected peripherally into the cylinder in pulses, timed by a valve which is controlled by movement of the inlet valve actuating mechanism of the particular cylinder. The boiler has multiple stages to ensure complete conversion of the water to steam, the peripheral steam injection providing internal cooling of the cylinder walls without interfering with normal combustion. The steam system is adaptable to existing internal combustion engines and results in reduced fuel consumption, very low pollutant emissions in the exhaust and a very efficient thermal cycle.
