気量を制限する吸気シヤツタを設けたアルコール
エンジンにおいて、エンジン冷却水温を検出する
手段と、排気温度を検出する手段と、エンジン始
動時に冷却水温が設定値以下のときに吸気バーナ
を作動させると共に吸気シヤツタを閉じる手段と
、始動後に排気温度が第１の設定値まで上昇した
ときに吸気バーナの作動を停止させる手段と、同
じく排気温度が第１の設定値よりも高い第２の設
定値まで上昇したときに吸気シヤツタを開く手段
とを備えたことを特徴とするエンジン始動装置。 In an alcohol engine equipped with an intake burner that heats intake air in the intake passage and an intake shutter that limits the amount of intake air, there is a means for detecting engine coolant temperature, a means for detecting exhaust temperature, and a set value for the coolant temperature when starting the engine. means for activating the intake burner and closing the intake shutter when the exhaust temperature rises to a first set value after startup; and means for opening an intake shutter when the intake shutter increases to a second set value higher than the second set value.
