Claims

[Scope of utility model registration request]

A direct intake duct that directly introduces air from the air cleaner into the intake manifold, and a supercharge duct that introduces air from the air cleaner into the intake manifold via a supercharger and intercooler are installed side by side. In the diesel engine with a supercharger, an interconnecting duct connecting the supercharger duct between the supercharger and the intercooler and the direct intake duct; and a plurality of valves inserted into each of the air ducts, and the valves are automatically switched at the time of cold start to allow the discharge air of the supercharger to flow through the interconnecting duct and the direct intake duct without passing through the intercooler. A warm-up accelerating device for a diesel engine, which is characterized in that it is introduced into the engine.
