摘要： An engine enclosure for a construction vehicle which is simply constructed and small-sized, while improving the cooling efficiency and lowering the noise. The engine enclosure including: an engine hood 15 having an ambient air inlet port 24; and engine side covers 16 having ambient air inlet ports 38. The engine enclosure is constructed to include an ambient air screening wall around a muffler 5 so that the cooling ambient air taken from the ambient air inlet ports 24 and 38 may flow to a fan without contacting with the muffler 5. With this construction, the air around the muffler and especially at a high temperature in the engine room and the cooling ambient air taken from the engine hood and the engine side covers can be screened from each other so that the temperature rise in the cooling ambient air to be fed to a heat exchanger such as a radiator can be reduced to improve the cooling efficiency.
