OBD is referred to On Board Diagnostics system.CNG OBD II Sequential kit is advance computer based conversion kit system designed with a dual objective of to reduce emissions by monitoring the air fuel mixture of engine and also monitor functioning of various components. It’s live monitoring and tuning capabilities ensue smooth drive under different conditions and optimum performance. It gives option to the mechanic to interact with vehicle components through a laptop and diagnose various components which help to fix many problems and improve the performance of vehicle. The major components are-
Electronic Control Unit (ECU / ECM) is the most critical component of CNG Sequential kit. It works in synch with Electronic Control Module (ECM) of car and receive signals from various sensors, calculates and provides the CNG fuel for optimum gas operation of vehicle.
Rail Injector is a stepper motor controlled electronic injector which help in injecting fuel in different cylinders as per required firing sequence and amount.
Vaporiser is also known as Reducer. Its basic function is to reduce pressure of CNG and help it vaporize in vapours for proper combustion. It can also be connected with coolant of vehicle (optional) so that its working temperature is maintained high.
Tubing (Steel pipe)-
ARAI approved, thoroughly tested, seamless steel tubes are used to transfer fuel from tank to reducer. All pipes are PVC coated for further safety.
Sequential CNG level meter measure the pressure of the gas and provide the information about the level of fuel in your vehicle on dashboard directly.
Forged, toughened, Brass made CNG tank valve is used to hold CNG in gas cylinder and release as per requirement.
CNG filling valve-
CNG filling valve provide a sale inlet so that CNG can be filled inthe tank. This is also made of Forged and toughened brass.
Switch is the basic interface which enables interaction between user, ECU and vehicle. Specifically designed branded switches are made on automated machines ensuring endurance and reliability for long lasting use.
CNG is stored in strong seamless containers at a pressure of 200 bar (2900 psi),CNG in any approved cylinder is highly safe.CNG cylinders are put through exhaustive and extreme tests which include firing bullets at the canister, roasting it over a roaring bonfire and impact tests in which a crane drops the cylinder at multiple impact points. The rigorous manufacturing process backed with stringent testing norms make it safer than gasoline / Petrol tanks
Raghav LPG always provide fresh and approved Cylinders along with its kit and care should be taken to avoid use of old and re worked cylinders as they may not be tested for safety.
Hardware pouch is combination of various small parts of standard quality required for complete fitment of a kit. It contains clamps, nuts, ferrule, cable tie, connector, steel screw and plastic cover to tie kit's parts easily. Though these items sound simpler but use of excellent quality of hardware material is very important for long life of kit and fitment.
