초록 ▼

An air intake heating system and method for heating intake air for internal combustion engines is disclosed including a microprocessor based controller, intake manifold air temperature monitoring means, engine speed monitoring means, and electrical air heating elements actuated by the controller in response to various combinations of sensed engine speed, sensed intake manifold air temperature and sensed battery condition. Air intake heating is provided to assist cold weather starting of engines as well as for minimizing white smoke pollutants produced by diesel engines after starting of the engine and as required thereafter during engine operation.

대표청구항 ▼

An air intake heating system for use with an internal combustion engine having a battery and corresponding charging system, said air intake heating system comprising: (a) temperature monitoring means for monitoring intake manifold air temperature, said temperature monitoring means producing a temperature signal corresponding to the intake manifold air temperature; (b) engine speed monitoring means for monitoring rotational speed of said engine, said engine speed monitoring means producing an engine speed signal corresponding to the rotational speed of said engine; (c) electrical air intake heating means for heating intake manifold air; (d) first circuit means responsive to said temperature signal and said speed signal, said first circuit means producing a first heating signal when said temperature signal is below a predetermined preheat limit and said speed signal is below a predetermined cranking limit; (e) second circuit means responsive to said temperature signal and said speed signal, said second circuit means producing a second heating signal when said temperature signal is below a predetermined postheat limit and said speed signal is above a predetermined running limit; (f) third circuit means responsive to said temperature signal and said speed signal, said third circuit means producing a third heating signal when said temperature signal is below a predetermined recycle limit and said speed signal is above a predetermined running limit; and (g) fourth circuit means responsive to said first, second and third heating signals, said fourth circuit means supplying a power signal from said battery to said electrical air intake heating means in response to said first, second and third heating signals.
