Abstract

The invention provides a self-rectification type diesel engine air inlet flame warmer. The self-rectification type diesel engine air inlet flame warmer comprises a warmer base, a warmer outer barrel, a warmer inner barrel, an electric heating plug, a fuel nozzle and related components; the warmer outer barrel is used for guiding air flow in the air inlet pipe into the warmer; the warmer inner barrel and the warmer outer barrel are eccentrically arranged; the warmer inner barrel and the warmer outer barrel jointly organize the air flow to form an internal stable wind field; after the glow plug is powered on, the glow head of the glow plug is used for igniting diesel oil spray sprayed by the fuel oil nozzle; and high-temperature fuel gas generated by combustion is mixed with inlet gas, and then the inlet gas of the diesel engine is heated. The self-rectification type diesel engine air inlet flame warmer has the beneficial effects that in the starting process of a diesel engine, reliable ignition is achieved by spraying fuel oil to the glow plug incandescent head; a stable wind field is formed by organizing gas flow in the gas inlet pipe through the structure body; stable combustion in the combustor is guaranteed; and the working reliability and stability of the gas inlet flame heater can be improved.

Description

technical field [0001] The invention relates to the technical field of diesel engines, in particular to a self-adjusting air inlet flame heater for diesel engines. Background technique [0002] As a power device, diesel engine is widely used in power devices such as automobiles, ships, locomotives and stationary power stations due to its technical characteristics such as high power, low fuel consumption, and high reliability. However, under low-temperature environmental conditions, the diesel engine will have difficulty in igniting and combustion deterioration due to the decrease in the end-of-compression temperature, which seriously affects the starting performance and working reliability of the diesel engine in cold regions. During low-temperature start-up, preheating the air before it enters the cylinder of the diesel engine can significantly increase the temperature at the end of compression in the cylinder, thereby greatly improving the low-temperature start-up performa...
