The invention provides a fuel treatment system for cracking hydrocarbons in fuel for combustion engines. The system comprises a primary ducting component having an exhaust gas inlet zone, and a secondary ducting component which includes a fuel enrichment component and a processing chamber. The processing chamber may have an outlet zone connectable to the combustion engine. The inlet zone of the primary ducting component and the outlet zone of the processing chamber may be configured in a heat exchange relationship with each other and in a counter-current gas flow direction with respect to each other. During operation of the system, heat from hottest volumes of the exhaust gas flowing in a furthest upstream portion of the ducting arrangement may be transferred to fuel-enriched exhaust gas flowing in a furthest downstream portion of the processing chamber. The system may include turbulence-inducing formations, including vortex-inducing formations configured in accordance with mathematical sequences such as the Fibonacci sequence.

A gas powered internal combustion engine in which the gas is provided from the gas phase of a pressurized liquid gas in an liquified petroleum gas container and in which the liquified petroleum gas container is rigidly mounted adjacent to the internal combustion engine at a preselected angle to be in conductive heat transfer relationship to the internal combustion engine and in vibration receiving relationship to the internal combustion engine whereby the liquified gas in the liquified petroleum gas container is heated and vibrated and the effective surface area thereof is thereby increased. A pressure regulator is provided for receiving the gas from the liquified petroleum gas bottle regulating the pressure of the gas transmitted to the internal combustion engine and at least one flexible hose is connected to the pressure regulator for transmitting the gas therethrough. A vibration and/or heat limiting member may be incorporated to reduce the frequence and amplitude of the vibration and limit the amount of heat transferred to the liquified petroleum gas.

A heat storage cover is provided in an engine room. The heat storage cover covers an engine from above and surrounds the periphery of an upper portion of the engine to internally store, through the medium of air, heat dissipated from the engine and block upward heat dissipation. The engine includes an air inlet for introducing, into a combustion chamber, high temperature air obtained by the heat storage cover blocking the upward heat dissipation.
