System Overview

4. Landi Systems Overview

Landi designs and produces “ready to go” LPG / CNG systems covering
Landi focuses on optimising the installation process, engine endurance, vehicle
performance and exhaust emissions
CNG/LPG systems mainly consist of the following components:
– OEM and aftermarket installation
– Any type of alternative fuel from LPG to CNG and CNG hydrogen
mixture
–
–
–
–
–
–
Pressure reducers and vaporizer (only LPG)
Valves / electrical valves
Injectors
Electronic control units
Switches
Air / fuel mixers
Landi does not produce the tank
Landi gas fuel systems are installed “on top” of the existing petrol fuel system,
allowing the vehicle to be operated by both fuels

Omegas system features

17. Omegas system features

The last generation car technological level represents a
new challenge for the producer of LPG and CNG
converting systems, due to emission levels, diagnostic
devices required by the new laws, performance and
driving desired by the costumers.
These facts drove LANDIRENZO to project OMEGAS, the
new LPG and CNG sequential multipoint “corrector”
injection system with electro-injectors.
The components of OMEGAS are designed by
LANDIRENZO in order to be qualified like standard
O.E.M. components, with the possibility to be tailored
according to the specific requirements.

18. Diapositiva 18

It’s a gaseous, phased, multi-point sequential injection system:
Gaseous: the system injects gaseous fuels (like LPG or CNG) into the intake
manifolds, the closest possible to the intake valves of the cylinders;
Multi-point: The gas is injected very close to the intake port of each cylinder
Phased: the injection feed each cylinder phased with the position of the piston position
Sequential: the cylinders receive the gas one after the other, according to the engine
cycle phase in which they are.
System is suitable for:
Full group injection system
Semi sequential injection system
Sequential injection system

OMEGAS CONTROL SYSTEM
The control system is slave type ECU. This means that the petrol ECU remains fully
operational and calculates the petrol injectors injection timing according to the signals
given by the car sensors (lambda sensor signal being the most important one);
Using some more sensor signals and the relative appropriate algorithms, Omegas
processes these petrol ECU outputs as inputs, to obtain the correct gas injectors injection
timing from petrol ones;
Omegas, then, takes care to physically avoid petrol injection uncoupling the petrol
injectors.

23. Diapositiva 23

Operating strategy: master/slave system
Master ECU (petrol one) doesn’t know about new ECU; it works also in gas mode
and all diagnosis are performed (the same running in petrol mode)
EOBD diag (misfire, catalyst, oxygen sensor,…) will be done by master ECU in
both mode (petrol and gas). With EOBD tester is possible to check diag. stored
with standard PCODE and freeze frame as when a fault occurs in petrol mode.
In addition LANDIRENZO ECU is capable to perform electrical and functional
diagnosis on proper sensor/actuator set.
Fault detected by LANDIRENZO ECU are stored into an internal memory; by
calibration they can be evidenced to the driver with a buzzer/LED blinking code on
the switch and major faults produce a switch back to petrol mode.

Omegas System is not suitable for these engines
Single point injection system
Multipoint injection car without oxygen sensor (system would work but
it’s very difficult to calibrate so it’s better avoid unless necessary)
Direct injection engines like
VW group FSI and TFSI engine
Alfa JTS engines
Mitsubishi GDI
BMW new IS engines
It’s possible retrofit some of these engine by the new “Omegas Direct
System”

Coolant temperature signal
Original Water
Sensor
Wire to connect to
gas harness
The coolant temperature signal is used to have a
precise information about the engine temperature
during the warm up and the normally run to gas.
Is possible:
• read to original temperature sensor (in the software
is present a procedure that allow to parameterize the
original sensor of the car).
• read the temperature with an additional T sensor not
included in a KIT.
•In case of temperature sensor not connected the
engine will activate a recovery procedure which
manage the switch on the gas temperature but is
much safer, especially in cold climate, have the
correct value of the coolant temperature

30. Diapositiva 30

TEMPERATURE SENSOR
(optional)
The water temperature sensor is
fitted on the water pipe just
before the gas pressure
regulator.
The signal transmitted to the
GAS ECU is necessary for the
correct work of the system.

This signal is directly read to original MAP sensor
of the car.
In the software is present a procedure that allow
to parameterize the sensor.
If isn’t present the MAP sensor in the software is
present other strategy to manage the return to
gas when the gas tank is empty.

to make it working in 3-4 cylinder engine
but it’s needed to use the 5-6-8 cylinder
harness

The new switch has the same function of the previous model.
A new “buzzer” is inserted to inform the driver of the change over to
