Embodiment Construction

[0015] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, and the described specific embodiments are only for explaining the present invention, and are not intended to limit the present invention.

[0016] The invention affects the subsequent oxidation process of low-temperature products by controlling the cooling temperature curve after fuel reformation.

[0017] The present invention mainly cools the reformed product reformed in the external low-temperature fuel reformer 8 at different speeds, and then passes the finally obtained reformed gas into the engine intake pipe 14, and finally introduces it into the engine cylinder 15 Participate in burning.

[0018] Such as figure 1 As shown, a low-temperature fuel reforming device external to an engine with a controllable cooling temperature device of the present invention includes a compressor 1, and the outlet of the compressor...

Abstract

The invention discloses an engine external reforming unit with a cooling temperature controllable device. The engine external reforming unit comprises an external reformer with the cooling temperaturecontrollable device. An inlet of the external low-temperature fuel reformer is connected with an air inlet pipe and a fuel injection pipe. The air inlet pipe is connected with a gas compressor and aflow meter. The fuel injection pipe is connected with a fuel injection pump and a fuel gasifying tank. An outlet of the external low-temperature fuel reformer is connected with an engine intake duct.Initial reformed fuel and fresh air are controlled and guided into the external low-temperature fuel reformer through the fuel injection pump and the gas compressor correspondingly and have a reactionin the reformer to obtain reformed gas, and the reformed gas is guided out from the outlet of reformer and passes through the cooling temperature controllable device. The engine external reforming unit adjusts the speed of controlling the cooling temperature to drop by the cooling temperature controllable device, guides required gaseous low-temperature oxidation products with different activitiesinto the engine intake duct to be mixed with fresh air and then guides the mixed gas into an engine to achieve activity and concentration stratification cooperative controlled burning of the mixed gas.

Description

technical field [0001] The invention relates to an external engine reforming device, in particular to an engine external reforming device with a controllable cooling temperature device. Background technique [0002] With the continuous shortage of energy in human society and the deteriorating environment, governments of various countries have formulated regulations to increase restrictions on vehicle energy consumption and emissions. In response to increasingly stringent laws and regulations, scholars at home and abroad have proposed a series of new combustion methods, such as homogeneous compression ignition (HCCI), partial premixed combustion (PPC), etc., these combustion methods are in varying degrees Improved engine performance. Among them, fuel reforming, a new combustion technology, has gradually attracted the attention of scholars because it can improve the combustion and emission of the engine. Peucheret et al. used a simplified thermodynamic equilibrium model to s...
