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.

In an aspect, a system includes a mixer configured to mix a fuel stream with a solvent to form a mixed stream, the solvent having a higher affinity for a second component of the fuel stream than for a first component of the fuel stream. The system includes a first separator configured to separate the mixed stream into (i) a first fuel fraction including the first component of the fuel stream and (ii) a mixed fraction including the second component of the fuel stream based on a difference in volatility of the first fuel fraction and the mixed fraction. The system includes a second separator configured to separate the mixed fraction into a second fuel fraction including the second component of the fuel stream and a solvent fraction.

A fluid pressure regulation and conditioning module comprises a metal manifold including a fluid flow path between fluid inlet outlets, a pressure regulator assembled to the metal manifold and disposed along the fluid flow path for regulating the pressure of the fluid exiting the module, and a filter assembly. The metal manifold further includes, for heating of the metal manifold with an externally supplied heat exchange media, a heat exchange media flow path extending between heat exchange media inlet and outlet. The filter assembly includes a metal filter housing and a filter element contained within the metal filter housing, the metal filter housing being in direct thermal contact with the metal manifold whereby heat from the metal manifold can flow to the metal filter housing for heating of the fluid not only in the metal manifold but also within the metal filter housing.

The present invention discloses a novel low-temperature fuel reforming unit based on combined external reformer of an engine, comprising an engine cylinder and an external low-temperature fuel reformer; the external low-temperature fuel reformer is winded with a heater strip and is provided with a first temperature controlled meter, the inlet of the external low-temperature fuel reformer is connected with a air inlet pipe and a fuel sample injection pipe, and a flow meter is arranged on the air inlet pipe; the fuel sample injection pipe is connected with a fuel injection pump and a fuel vaporization tank which is provided with a second temperature controlled meter; the outlet of the external low-temperature fuel reformer is connected with the engine inlet pipe via a reforming gas pipe; and the reformed low-temperature products enter into the engine inlet pipe via the reforming gas pipe for combining with the fresh air again to form a uniform hybrid gas, and the hybrid gas is introduced into the engine cylinder and performing combined combustion with the fuel in the cylinder to achieve activity and concentration stratification of hybrid gas. Since the above process does not need adding catalyst, the engine of the present invention can be operated more efficient and energy-saving.
