Embodiment Construction

[0026] Currently, air heaters take many seconds to heat up to a temperature such that the heat generated by the air heater is sufficient to heat the intake air of an engine (eg, a diesel engine). The present disclosure is directed to an air heater that includes relatively short heating elements arranged in a honeycomb structure to reduce heating time and provide a durable construction that mitigates heating elements from overheating or vibration. damage. The air heater may also fill the intake path or throat of the engine intake to minimize cold spots.

[0027] The present disclosure also relates to an air heater controller capable of determining the air heater temperature and controlling the current supplied to the air heater to achieve and maintain a desired operating temperature. This way, even if the engine controller activates the air heater system longer than necessary, the air heater will not reach an overheated condition.

[0028] The air heater controller may receiv...

Abstract

An air intake assembly includes a heating element. The heating element includes a bend arranged in a serpentine configuration and having crest portions and trough portions. At least one peak portion of the first heating element is secured to a corresponding valley portion of the second heating element. The heating elements are arranged in a honeycomb configuration.

Description

technical field [0001] The present disclosure relates to an air intake heating system in an internal combustion engine, and more particularly to an air intake assembly having a heating coil and electronic control of an air intake heating system including the air intake assembly. Background technique [0002] The air-fuel mixture used in internal combustion engines is difficult to ignite when cold, resulting in incomplete combustion and increased emissions. Once the engine warms up, the cylinders can sufficiently heat the air-fuel mixture. However, at start-up, the engine may not contribute heat to the air-fuel mixture. Cold start conditions are particularly severe when the ambient air temperature is low. The air intake heating system can be used to heat the air reaching the engine. This system can be located in or before the intake manifold. The air intake heating system can reach temperature before attempting to start the engine. [0003] Heating the intake air makes i...
