A preheater body is formed by alternately connecting each heat storage exchanger and each built-up heating body together by rivets and a straight air passage is formed in the preheater body . The preheater body is installed in the outer housing by attaching two outermost heat exchange plates of the preheater body to two adiabatic rings on the inner wall of the outer housing and a surrounding air passage is formed between the outer housing and the preheater body . A diesel engine may start at temperatures as low as −45° C. by means of the preheater and airflow has no adverse effect on the operation of the diesel engine.
