(1) Do not open the radiator compartment bulkhead at will or use it as a heat transfer process for vortex components. It is not always casual due to the effects of high temperature de-aeration.
(2) Some exhaust vents in each nacelle are well known, so insist that the protection of the engine bottom and the exhaust vent pump will prevent the appearance of objects and place or stop the exhaust heat. Is. Reducing the air intake will increase the temperature of the cabin and increase the intake air temperature. In addition, premature ageing due to high temperatures can damage electrical components.
2. Air inlets
In addition to avoiding hot air returns and ventilated areas, one factor that affects airflow is the air hood and fan. Today, the fume hood consists mainly of venturi tubes, rings and boxes. The orientation of the fan and hood is strictly required and also the distance between the fan and the engine. As the hood is usually used to increase the power of the fan, the air is evenly distributed through the radiator core, thus preventing hot air from flowing back into the engine compartment.
3. Intake resistance for intake temperature scale specification (Cummins engine intake resistance 6BT5.9 specification ≤ 15in H0o) engine output decreases by 1% when intake temperature is 38°C or higher and engine output increases by 6°C. 1.5% warranty)
