Air intake heating device and engine for cold start of engine

Abstract

This specification discloses an intake air heating device and engine for cold start of the engine, the device includes: intake fuel injector, intake duct, battery, heater, reactor, battery positive pole, battery negative pole, wherein: the reaction The reactor is installed in the pipeline near the end of the engine, and the central axis of the reactor is consistent with the central axis of the inlet. The structure of the reactor is a columnar structure with multiple channels, and each internal channel of the reactor The cross-sectional shape is hexagonal, and the hexagonal cross-section between two adjacent internal passages has one side, and the surface of the internal passage is coated with precious metal materials; the intake fuel injector passes through the hole reserved on the intake passage The nozzle hole of the intake fuel injector is installed, and the nozzle direction of the nozzle points to the inlet of the reactor; the heater is arranged in the reserved space of the reactor, and is adapted to the size of the reserved space, and One end of the heater is connected to the positive pole of the battery, and the other end of the heater is connected to the negative pole of the battery.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an intake air heating device and an engine for cold starting of an engine. Background technique [0002] At present, the diesel engine is in a low temperature environment, due to the low intake air temperature, the engine is difficult to start, and the cold start of the diesel engine at low temperature is difficult. At low temperature, the air intake temperature and the cylinder liner of the diesel engine are the same as the ambient temperature, the piston compresses to the top dead center to dissipate heat, the temperature at the end of compression is low, the diesel oil is poorly crushed and atomized, and it is difficult to compress and ignite. In the prior art, the glow plug is mainly installed in the intake port. Due to the large intake flow of the diesel engine, but the heating area of ​​the glow plug is small, the heating effect is not obvious, and the time required for hea...

AI Technical Summary

Problems solved by technology

In the prior art, the glow plug is mainly installed in the intake port. Due to the large intake flow of the diesel engine, but the heating area of ​​the glow plug is small, the heating effect is not obvious, and the time required for heating the temperature rise is long , and heating energy consumption puts forward higher requirements on the capacity of the battery equipped with the vehicle, and because the storage capacity of the battery is severely reduced at low temperatures, the implementation of this scheme is poor
