Means for detecting the intake air temperature and alcohol injection amount are provided, and these detection means detect whether the engine speed, load, intake air temperature, etc. are low or the alcohol injection amount is large and the compressed gas temperature in the engine combustion chamber is not significantly reduced. 1. An intake system for an alcohol-using engine, characterized in that an intake air heating control means is provided for opening a passage for heating the intake air by the intake air heating means when an operating condition is detected. (2) The intake passage is a main passage without intervening intake air heating means;
a bypass passage interposed with an intake air heating means, and
The structure includes a switching valve that changes the flow path area ratio of both passages, and the intake air heating control means is configured to drive the switching valve to change the proportion of intake air flowing through both the passages. An intake system for an engine using alcohol as claimed in claim 1.
