How to choose the nozzle diameter
The choice of nozzle diameter depends mainly on the unit displacement and the power developed by each cylinder .
To determine the cylinder displacement:
Total engine displacement ÷ number of cylinders = displacement per cylinder
For example, for a 1400cc 4-cylinder engine:
1400 ÷ 4 = 350 cm³ per cylinder
According to the Landi Renzo table, a configuration of 350 cm³ per cylinder corresponds to Ø 2.0 mm nozzles .
Power per cylinder can also be calculated as follows:
Total power ÷ number of cylinders = power per cylinder
Example for an 85 kW, 4-cylinder engine:
85 ÷ 4 = 21.25 kW per cylinder
The selection of nozzles must therefore take these two parameters into account.
Landi Renzo nozzle selection chart
| Cylinder displacement | 10 to 15 kW | 15 to 20 kW | 20 to 25 kW | More than 25 kW |
|---|
| 200 to 280 cm³ | 1.8 mm | 1.8 mm | — | — |
| 290 to 370 cm³ | 2.0 mm | 2.0 mm | 2.2 mm | — |
| 380 to 440 cm³ | 2.0 mm | 2.2 mm | 2.2 mm | — |
| 450 to 500 cm³ | 2.2 mm | 2.4 mm | 2.6 mm | — |
| Over 510 cm³ | — | — | — | — |
Example 1: 1.4 litre / 4 cylinder engine → 350 cm³ per cylinder → nozzles Ø 2.0 mm .
Example 2: 85 kW / 4-cylinder engine → 21.25 kW per cylinder. For a 350 cm³ per cylinder engine, the configuration also corresponds to Ø 2.0 mm nozzles according to the table.
Nozzles available separately
If the 2.2 mm diameter does not fit your configuration, different diameters of Landi Renzo nozzles are available separately on our website.
Consult the relevant product sheet to select the diameter suitable for your installation.
Important: the choice and adjustment of the nozzle diameter must be carried out according to the exact configuration of the vehicle and the Landi Renzo LPG system installed.
