Protective heat shield enclosure for turbocharged engines

An engine assembly for a vehicle, comprising:

• an internal combustion engine including an exhaust manifold configured to discharge exhaust gases;
• a turbocharger, coupled to the exhaust manifold via an exhaust coupling conduit, configured to receive the discharged exhaust gases to drive the turbocharger to produce compressed air delivered to the engine;
• a dual-layered heat shield comprising:
• a first heat shield layer including:
• an upper section arranged to cover the engine exhaust manifold;
• and
• a lower section arranged to cover a portion of the turbocharger;
• wherein, the first heat shield layer upper and lower sections are configured to conform to general shapes of the engine exhaust manifold and turbocharger surfaces, respectively;
• and
• a second heat shield layer covering the first heat shield layer upper and lower sections, the second heat shield layer including:
• an outer surface configured with a curved shape to accommodate the shapes of the first heat shield layer upper and lower sections for coverage;
• wherein, the second heat shield layer is disposed to be spaced apart from the first heat shield layer upper and lower sections by an air gap of at least 10 mm,
• the first heat shield layer upper and lower sections being formed from sheet steel with malleable properties,
• the second heat shield layer being formed from sheet aluminum having a greater thermal conductivity than the sheet steel.
