SPECIFICATION OF GAS SUPPLY TO TECJET 52
2/3
Where gas temperatures exceed the value used in the graph, the minimum pressure required for a given
power will increase. Consult
Kohler
.
Using a Tecjet 52 valve with a gas of very high volumetric Low Heat Value (LHV) may affect accuracy
negatively, depending on the engine power and the gas pressure at the Tecjet. If the supply pressure is high for
a gas of very high LHV, small variations in the valve opening or supply pressure may lead to great variations in
the carburetion of the engine. For this reason, we specify a maximum supply pressure to the Tecjet for Natural
Gas and propane.
The graph below shows the maximum pressure requirements as measured at the inlet to the Tecjet 52 valve
related to engine power and gas quality under normal conditions.
