RADIATION HEAT – HOT SOAK TEMPERATURE
If the engine is shut down when hot, the flow of cooling air is stopped and the temperature in the enclosure will rise
suddenly.
Provide ventilation on top of the enclosure to prevent the engine compartment temperature from rising too high
after the engine has been stopped.
Especialy the fuel system is sensitive to temperature rise after engine stop;
High temperature in fuel lines, carburetor or fuel tank may develop vapor lock and resulting starting problems.
The fuel temperature in the carburetor float chamber should be checked 10 – 15 min after the hot engine has been
stopped; fuel temperature should stay below the Honda standard (max. 60°C).
AIRFLOW REFLECTION
When mounting the engine on an application, avoid
that cooling air or exhaust gas is reflected by any
shield or panel.
The reflected hot airflow will increase the temperature
of several components and may lead to an overheated
engine and fuel vapor lock.
To verify that an engine installation provides satisfactory cooling, it requires a careful test program
under the most realistic, severe operating conditions.
Be sure that the engine meets all temperature requirements as stated in the Honda standards.
