According to the methanol engine system and the operation method of the methanol engine system, methanol-based fuel is adopted for the reaction to generate the hydrogen serving as the ignition agent, ignition agent preparing and stable, continuous and accurate supply to the engine are achieved, and completely replacing the diesel fuel with the methanol-based fuel is achieved under the situation of no need to change the structure of the engine.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a methanol engine system using methanol as a igniter for hydrogen production and an operating method thereof. Background technique [0002] Methanol has received widespread attention due to its low price and low emissions from combustion in engines, especially in China, which has an extensive methanol supply chain. At present, the application of methanol as fuel in gasoline engines has achieved success, but the application of methanol in diesel engines has not made a breakthrough. Since the cetane number of methanol is very low, only about 3, it cannot be compression-ignited when applied to diesel engines, and it is very difficult to apply it to compression-ignition diesel engines. Therefore, in order to apply methanol to diesel engines, the main research direction of researchers is dual-fuel combustion, that is, the application of methanol-based fuels to diesel engi...
