OUR VISION
To become a world class organization acting on opportunities that
create wealth by adding values to the assets of our clients through
the provision of cost effective service with safety and environment
as top priority.
Our areas of specialization include:
A. CONVERSION OF MOBILE DIESEL ENGINES (Such as Luxurious Buses,
Trailers, Trucks, Tractors, Diesel Engine Buses / Cars, refuse haulers, Constructions
Equipments, Trains e.t.c.) to BI-FUEL SYSTEM that will use both Diesel and
Compressed Natural Gas (CNG) at the same time.
CNG CONVERSION KIT DESCRIPTION AND THEORY OF OPERATION IN
DIESEL ENGINE (BI-FUEL)
The Bi-fuel Conversion System is a retrofit technology that allows diesel engines to
operate on a mixture of diesel fuel and natural gas. This is achieved through the use
of proprietary and patented technology that is installed externally of the engine.
Conversion to bi-fuel mode requires no major changes or modifications of the engine
and allows the engine to operate on gas mixtures ranging from 50% to over 70% of
total fuel consumed. After conversion to bi-fuel, the engine can still operate on 100%
diesel without loss of power or efficiency. The system has been designed to allow for
switching of fuel modes during full or part load conditions, without interruption in
engine speed, power or stability. The system utilizes a fumigation gas delivery
method during which gas is delivered to the cylinders via the standard engine airintake
system and is then ignited by a diesel “pilot” which acts as the ignition source
for the air / gas mixture.

B. CONVERSION OF MOBILE PETROL ENGINES ( cars, Petrol engine buses/ trucks
etc) into 100% Natural Gas engines using CNG in cylinders without any alterations to the
engine.
CNG CONVERSION KITS DESCRIPTION IN PETROL ENGINE (MONO FUEL)
The Mono-fuel Conversion System allows petrol engines to operate on either petrol or
natural gas but not the two fuels at the same time as in the case of diesel engine
conversion system. Conversion to mono-fuel mode requires no major changes or
modifications of the engine and allows the engine to operate on either 100% petrol or 100%
natural gas. After conversion, the engine can still operate on 100% petrol without loss of
power or efficiency. The system has been designed with a manual switch on the dash
board for user to select the fuel mode either natural gas or petrol. If on petrol the system
uses the engine OEM timing and injector modules and when on natural gas due to
differences in response and ignition point of the two fuels, natural gas requires Timing
Advance Processor as well as Injector Emulator The injector emulator sends the required
signal to the engine to enable it use 100% natural gas.

C. SALES INSTALLATIONS AND AFTER SERVICES MAINTENANCE OF DIESEL /
NATURAL GAS BURNERS AND LPFO (LOW POUR FUEL OIL) / NATURAL GAS
BURNER. All regulations and setting devices are simple and practical for both fuels. For
LPFO / natural gas burner, provision is made for a pre-heating tank equipped with low
thermal load electrical resistance to keep the LPFO in fluid state.

D. CONVERSION OF DIESEL ENGINE GENERATORS TO BI-FUEL SYSTEM that will
allow engine to use both diesel and pipeline gas or CNG as may be requested by the
client.
The Bi-Fuel System uses a proprietary air-gas mixing device that has been designed for
optimum blending of natural gas and engine intake air. Mixing of air and gas is achieved
using a sophisticated, fixed venturi design that avoids the use of an efficiency robbing
throttle plate. The low restriction air-gas mixer ensures that adequate air-flow is
maintained to the engine and that operating efficiencies are not compromised by
installation of the device.

Gas Train
Conditioning and regulating the natural gas prior to admission into the engine is a critical
part of the Bi-Fuel System. The system “gas train” includes a 50-micron fuel filter, an
electrically-operated solenoid valve, actuated in the event of an emergency or for system
shutdown, and a zero pressure, demand-type gas pressure regulator. This latter
component reduces the inlet gas pressure (3 ±1 psi) to roughly atmospheric pressure.
With a negative outlet pressure, the design allows the system to use a “demand” control
scheme whereby engine intake airflow determines the gas flow of the engine. As engine
load changes, corresponding changes in intake air volume automatically draw additional
fuel into the mixer.
Integrated Mixer Throttle Body
Flame Detector
Gas Detector
Typically, gas is introduced downstream of the engine air cleaner and upstream of the
turbocharger. The gas is supplied at approximately atmospheric pressure using a
proprietary air-fuel mixer that allows for a high level of gas mixing with the least possible air
restriction. The air-gas mixture is compressed in the turbocharger and distributed to each
cylinder by the engine air intake manifold. The lean air-gas mixture is compressed during
the compression stroke of the piston and ignited by the diesel injector. Since the air-gas
mixture is maintained in a lean condition, pre-ignition does not occur.
Flow of gas to the engine is load dependent and varies with combustion airflow changes.
The Bi-Fuel System varies gas flow according to changes in engine vacuum level. This
allows it to respond to engine fuel requirements while maintaining the integrity of the OEM
governing system. The standard Bi-Fuel System incorporates an integrated Mixer Throttle
Body that varies the gas flow base on the power output from the generator. Diesel injection
is controlled by the OEM governing system during both gas and diesel modes.
The Bi-Fuel Control panel with ECU monitors various engine and system parameters such
as manifold air pressure and temperature, exhaust gas temperature, gas pressure and
engine vibration. This information allows the controller to determine when to activate or
deactivate bi-fuel operation depending on engine performance, load level, ambient
temperature, knock limits or gas supply pressure levels.

SAFETY FACTORS
Safety is a critical element in the design,
installation and operation of any appliance. This
element has been taken into serious consideration
when the Bi-Fuel System was being designed.
The following safety factors have been built
into the system:
Gas is supplied into the engine at atmospheric
pressure thereby reducing the possibility of over
supply. Gas concentration the engine combustion
chamber is less than 3% by volume.
This means that the possibility of explosion in the
combustion chamber is almost non-existent. The
air/gas mixture is non-explosive, non-flammable
until compressed in the combustion chamber.
CNG has an ignition temperature of above 600
degrees C which is approximately four times
higher than diesel. This means that the danger of
an explosion, deflagration or a fire is much lower
than that of diesel.
TECHNOLOGY OVERVIEW
Co-firing of diesel and natural gas in diesel engines with 60 /
40 gas / diesel ratio.
No engine modification required.
No power or efficiency loss in diesel engine.
Designed for severe on-road services.
Fail-safe design: the system automatically defaults to 100%
diesel fuel mode in diesel engines.
Automatic switching of fuel modes in diesel engines.
Electronic monitoring of critical parameters.
Compatible with turbocharger and normally aspirated diesel
engines.
Retrofit kits.
Easy to install.
ADVANTAGES
Lowest Cost Fuel – When comparing the cost to that of
Diesel, Low Pour fuel oil (LPFO) and Petrol in fueling vehicles
or generators.
CNG is lighter than air. Therefore if a leak were to
occur anywhere along the system line before
entering the combustion chamber, the gas will
simply rise up and quickly dissipate into the
atmosphere.
Furthermore, CNG gas cylinders are designed and
built with special materials with the highest safety
specifications to withstand even explosion by
dynamite.
Automatic shut down of gas supply if fault is
detected by the electronic sensors supplied with
the system.
CNG / LNG on-board fuel systems have excellent
safety history world-wide.
