とを特徴とするアルコールエンジン。 An exhaust manifold connected to the exhaust port of the engine body, a first exhaust passage and a second exhaust passage branched and connected to the collecting pipe of the exhaust manifold, and provided in the first exhaust passage so as to be openable and closable. a first opening/closing valve that is closed only when starting at a low temperature and opens during other normal operations; and a second on-off valve that is openable and closable in the second exhaust passage and is opened only when starting at a low temperature and closes during other normal operations. This on-off valve is installed in series with this second on-off valve, and cools the exhaust gas guided through the second on-off valve during cold start, condenses and removes moisture contained in the exhaust gas, and removes white matter from the exhaust gas discharged to the outside. An alcohol engine characterized by being equipped with a cooler that reduces smoke.
