Equipment for NGV vehicles
Natural gas can be used to fuel almost any kind of vehicle - motorcycles and three wheelers, cars, vans & pickups, lift trucks, buses, trucks.
Equipment for NGV vehicles
1. Carburettor Mixer System
Conversion On Carburettor type Engine for petrol vehicles. This type of conversion is also known as conventional NGV Conversion. The Mixer system is compensate 5% to 15% power of the car, manually means it need to press a button to change betweeen modes from NGV to petrol or vice versa when the NGV is used up or otherwise (bi-fuel system).
2. EFI Fuel Injection Mixer System
EFI Fuel Injection Mixer System NGV conversion on EFI type engine for petrol vehicles. This type of Conversion is commonly know as closed loop system. This type of conversion is to cater for the advanced, faster compression and fuel programmed engines.
3. Sequential System
This is a more advanced system compared to Mixer System. Petrol is delivered from the NGV cylinder to the Pressure Regulator controlled by an ECU (Electronic Control Unit) which blend perfectly with original car's ECU. This advanced fuel injection system can installed in all injection vehicles (petrol). As it is direct injection there is less compensate on power; almost the same performance as using petrol. The Sequential Gas Injection System also optimizes consumption and performance can fully automatically switches from NGV gas to petrol or vice when the natural gas is used up.
4. Dual Diesel Fuel System (DDF)
NGV vehicles are being rapidly developed as economical and low-pollution cars. The potential benefits of using NGV in diesel engines are both economical and environmental. In the dual fuel gas engines, the gaseous fuel is inducted along with the air, and this mixture of air and gas is compressed like in conventional diesel engines.
A small amount of diesel, usually called the pilot, is sprayed near the end of the compression stroke to initiate the combustion of the inducted gas air mixture. With reduced energy consumption, the dual fuel engine shows a significant reduction in smoke density, oxides of nitrogen emission, and improved brake thermal efficiency.
ABOUT DIESEL ENGINE
A diesel engine is an internal combustion engine that uses the heat of compression to initiate ignition to burn the fuel, which is injected into the combustion chamber during the final stage of compression. This is in constrast to a petrol (gasoline) engine or gas engine, which uses the Otto cycle, in which a fuel/air mixture is ignited by a spark plug.
It operates using the diesel cycle. Diesel engines have the highest thermal efficiency of any internal or external combustion engine, because of their compression ratio.
ADVANTAGES OF DUAL DIESEL FUEL SYSTEM
Consumption of fuel save up minimum of 35% or more with NGV system.
Allows the use of available or interruptible gas supplies, Diesel System is still operated anytime without any change
No modification to internal engine components are required, the engine's OEM warranty is still valid where it is take off before goes back to garage.
Cleaner burning natural gas reduces exhaust emissions. The cleanliness of natural gas longer oil life and thus, lower maintenance costs. Less carbon residual, engine knocking or over-heat risk.
Reduces requirements for on-site fuel storage, more flexibility.
Unique, patented design ensures no loss of power or efficiency.
No potential risk of engines explosive while the sparks generated by Turbo-Charger. Engines are supervised by different sensors or regulators of ECU system in all times.
Low cost and easy to install
Carburettor engines mixer system has the least complicated installation process, as basically the switch process is semi-automatic. Just drop your car into our workshop and wait for just 3 to 5 hours and your car is ready to run on natural gas.
EFI engines mixer system take about a day (24 hours) to complete as the closed loop system need more equipments to complete the installation to mostly advanced car system.
Sequential system takes the longest period - some 2 to 3 days to install as it is vital that our ECU blends perfectly with that of the car's original ECU so that the fuel can be regulated and optimises. As the mechanism is fully automatic, the installation takes on further procedures to fit.
NGV fuel cylinders
The NGV fuel cylinder is a tested pressure vessel which is designed and constructed in accordance with strict Malaysian Standards. During manufacture it is subjected to controlled heat treatment. Therefore it is imperative that no welding, soldering, brazing or heating of the cylinder takes place after the manufacture of the vessel.
All cylinders must be securely and permanently affixed and must be capable of being filled in that position.
Some NGV fuel cylinders are constructed using fibreglass reinforced plastic (FRP) wrapped around the outside of the steel cylinder. This type of construction allows for a lighter NGV cylinder but it is important that the FRP layer is not damaged as this provides part of the cylinder’s strength.
All-steel cylinders and FRP reinforced steel cylinders must be inspected periodically. All-steel cylinders may continue to be used for as long as these inspections show that the cylinder remains sound, however FRP wrapped steel cylinders must be replaced after 15 years of use.
In the case of a converted vehicle, a CNG storage cylinder is usually installed in the trunk of the car. Apart from the loss of trunk space, the driver will notice little difference in the performance of the vehicle (though they will usually notice lower fuel costs). An OEM (production line) vehicle often has the CNG storage cylinder installed under a seat or elsewhere within the
chassis to minimize or eliminate the loss of luggage space.
