Methanol/ethanol trapped vortex micro-combustor pre-heating intaking method and device for automobile cold-starting

Abstract

The invention provides an auxiliary ignition method which is used for automobile cold start and in which air is preheated by standing vortex micro combustor and a device thereof, relating to the internal combustion engine technology. The method is that: a little carbinol / ethanol fuel is combusted in the micro combustor, generating high temperature fumes, and then the fumes mix with the combustion engine intake air, thereby improving the temperature of the air entering the combustion engine and resolving the problem of the cold start existing in the carbinol / ethanol automobile. The device is arranged behind an air cleaner and in front of an air intake manifold and comprises a standing vortex micro combustor and a carbinol / ethanol preheating evaporator. The carbinol / ethanol liquid make a mixed firing with the air in the micro combustor after the preheating evaporation of a preheater, and generates the high temperature fumes which mix with the main air flow of the automobile intake air. The invention resolves the problem of the cold start by increasing the temperature of the intake air; moreover, the device is simple and convenient in operation.

Description

technical field [0001] The invention relates to the technical field of internal combustion engines, and relates to a methanol / ethanol vortex micro-combustor preheating air intake method and device for automobile cold start. Background technique [0002] The trapped vortex combustor is a new type of technology that has been studied internationally since the 1990s and is mainly expected to be applied to gas turbines. Combustion is stabilized by the trapped vortex in the engine, thereby replacing the swirler with complex structure and adjustment. Structurally, a trapped vortex generator is formed in the cavity in the combustion chamber of the gas turbine, so that the fuel, air and gas from the combustion chamber enter the cavity to form a vortex, and part of the fuel in the combustion chamber is in a stable vortex flow structure. Mixes and burns quickly. During the movement of the vortex, the high-temperature smoke is continuously discharged, while the low-temperature fuel an...
