Air inlet heating device and engine

The utility model discloses an air inlet heating device and an engine, which are used for solving the problem that a traditional air inlet heating grid cannot guarantee the air inlet temperature of afar-end air cylinder, the air inlet heating device comprises air inlet heating wires arranged inside an air inlet pipe, and the air inlet heating wires are correspondingly arranged at ports of air inlet channels of all air cylinders. The air inlet heating device ensures that air entering each air cylinder is uniformly and effectively heated, so that when the engine is started at low temperature, each air cylinder can be ensured to have enough high air inlet temperature, and the low-temperature starting capability of the engine is improved. 本实用新型公开了一种进气加热装置与一种发动机，用于解决传统进气加热栅格无法保证远端气缸进气温度的问题，该进气加热装置包括布置于进气管内部的进气加热丝，每个气缸进气道端口均对应布置有所述进气加热丝。该进气加热装置保证进入各个气缸的气体均得到均匀有效加热，因此，在低温起动发动机时，可以保证各个气缸具有足够高的进气温度，从而提升发动机的低温起动能力。
