LANDIRENZO OMEGAS
LANDIRENZO's OMEGAS multipoint sequential injection system
represents a new generation of bi-fuel (gasoline - lpg)
gaseous LPG conversion system. Suitable for vehicles with
Sequential Petrol Injection with Lambda and Catalyst.

The principle used by the LPG ECU to calculate the injection
timing applied to the LPG injectors, is based on the acquisition
of the gasoline injection timing by LPG ECU during LPG mode.
The engine management is, therefore, mainly left to the
gasoline ECU whilst the LPG control unit translates gasoline
actuations into an appropriate control for LPG injectors.
In order to maintain the coherence with the gasoline system,
the LPG ECU drives LPG injectors in the same sequence as
gasoline injectors. Roughly, the LPG ECU converts an amount
of energy that should be actuated by the gasoline into an
equivalent amount of energy that LPG has to release in order
to compensate the differences between two fuels.
LANDIRENZO OMEGAS can use different types of injectors
according to the specifications of the application.
LANDIRENZO OMEGAS is minimally invasive with respect to
the original gasoline engine management system. It is able
to be easily integrated with the main engine management
functions as mixture control, cut off, EGR, purge canister,
etc and auxiliaries engine management functions as air-conditioning,
power-steering, electric loads, etc.
The LPG ECU is able to calculate LPG injection timing
using specific information as LPG injector rail pressure,
LPG temperature, engine coolant temperature, engine RPM
and battery voltage, in addition to the inputs of the gasoline
ECU.

LANDIRENZO IGSystem
The IGSystem has been designed and developed to integrate
with the most recent petrol injection systems. Suitable
for vehicles with Multi-Point Injection with Lambda and
Catalyst.
Here is a list
of vehicles successfully converted on IGS.
The IGSystem enables the conversion of a continuous gaseous
LPG injection in petrol injection engines that are provided
with lambda sensor (oxygen sensor) and three-way catalytic
converter.
The fuel coming from the tank goes through the reducer-vaporizer
that controls pressure and temperature, and enters the proportioner.
The proportioner establishes the flow of the fuel towards
the fuel distributor in function of the commands from the
Electronic Control Unit (ECU). The fuel distributor, while
apportioning the gas flow in each single conduit of the
intake manifold, maintains a constant pressure downstream
of the proportioner.
Since the system is compensated, it follows that the proportioner's
fuel supply pressure increases with the engine's load, while
maintaining a constant pressure downstream of the proportioner.
This increases the response speed during transience.
The mapping is bi-dimensional, while the information pertinent
to Manifold Absolute Pressure (MAP) and RPM is used to establish
the amount of fuel that must be injected for the best performance
and emissions results. The microprocessor modulates the
amount of gas in function of driving conditions so that
performance and emissions are constant even in different
environmental conditions and with fuel composition changes.
The microprocessor takes into account the engine's deterioration
and automatically corrects the fuel's reference parameters.
The fuel management is further refined by other functions:
such as oxygen sensor management strategies, fuel enrichment
in acceleration transients, and fuel cut-off in deceleration.
The IGSystem's ECU also controls other corollary functions
of the system, such as fuel level indicator, fuel switchover,
RPM governor, and ignition system-triggered fuel solenoid
valves' safety shut-off.
Interaction with the ECU can be achieved by means of a
serial interface with a PC or a scanner. This is possible
for diagnostic purposes, as well as during the first start-up
after the completion of the conversion, when the data files
pertinent to the vehicle that is being converted are uploaded
from the PC into the ECU. For diagnostics a check can be
made for proper operation of the sensors and the pressure/vaporizer,
while assessing the quality of carburetion.
