Engine enclosure for construction vehicles
First Claim
1. An engine enclosure for a construction vehicle of the cooling type, in which the cooling ambient air taken into an engine room from ambient air inlet ports formed in an engine hood enclosing the engine and in two engine side covers is forced by a fan toward a heat exchanger in front of said engine, comprising:
- an ambient air screening wall surrounding a muffler, which is disposed in an over-engine space defined in said engine room by the engine hood and the two engine side covers, so that said taken cooling ambient air may flow to said fan without any contact with said muffler.

Abstract
To provide an engine enclosure for a construction vehicle which can be simply constructed and small-sized while improving the cooling efficiency and lowering the noise.
An engine enclosure for a construction vehicle 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.
