Know Your BS-IV EVAP System(Evaporative Emission Control System)




While upgrading the BS-III to BS-IV Stage Government have made mandatory of EVAP system in all two wheeler, before going into deep first understand what it means.

In BS-III Type two wheeler there was a small pin hole located in the centre of the fuel tank cap. The purpose of this hole is simple just to release the fuel vapors from the fuel tank. If we park the vehicle under the sun light or outside gasoline get heat and fuel vapors are created and escaped through this vent to atmosphere. 

Why it harmful ?
Basically Gasoline is a Petroleum product, it contains variety of different carbon contents and also many chemical which are harmful to the environment and health. If the vapors of Petrol enters in the atmosphere it leads to adverse effect on environment and human health. It causes skin problems, asthma and many more disease. These lighter vapors reacts with air and creates smogs. 

How to control ?
By adopting simple system called EVAP (Evaporaive Emission Control system) we can control this. If you check the below image you will get rough idea of the system.

First Check the fuel tank cap it does not contains the air vent hole. Now think what happens to the vapor created inside the tank ? Instead of air vent a small tube provided inside the tank, it carrier all vapors created inside the tank to outside and other end of this tube is connected to the small sealed container called as Charcoal Canister.

Working of Charcoal Canister - is simple, it contains charcoal, the fuel vapors escaped from the fuel tank enter into the canister and stored inside.

In above figure you can check another tube coming from the carburattor bowl also looped in this circuit, this carries vapors from the carburettor to the canister (only for carburattor type and not applicable in FI System).

Out vent of the Canister is connected to the Purge Valve. This purge valves controls when these vapors has to be re feed to the engine through the carburettor. Let us know how the Purge valves operate.

Purge Valve - is a simple construction. It contains two chambers and  a  simper valve compressed against its seat by a spring.  In normal condition i.e engine off or running in idle or slow speed the valve is in closed position. In this position fuel vapors which travels from the canister stopped in the purge valve chamber, the valve does not allows to enter it into the carbuettor.

At the bottom side of the purge valve a small tube is connected to the Intake manifold, when engine RPM increases it leads to increase vacuum in the lower area of purge valve. This action cause to pull the Purge valve against its spring tension.

As soon as valve comes down fuel escapes through the passage and supplied to the carburettor. Now the fuel vapors stored in the Charcoal canisters escapes through the purge valve and enters into the combustion chamber through carburettor.

Now the cycles completes, In this system fuel tank is fully sealed and there is no vent for vapor escape to the atmosphere, what ever created inside it directly recycle through the charcoal canister and feed back to the engine.

How to check oil level in your Royal Enfield

Oil is an important thing in internal combustion engine. It lubricates all moving internal parts of the engine and protect against wear and tear caused by friction. Apart from this it also helps to cool the engine.



How to check the oil level

It is best practice to check the oil level on every day morning before take it into the ride. Place the vehicle in to the main stand on level ground. Start the engine, please don't race the engine too hard, it will harm the engine, after two  minutes it will stay on smooth idle. Till it warming check the working of all other electrical parts like horn, light, battery charging etc.

For All model except the Himalayan 

Once it warm up then switch off the engine and check the inspection glass window located RH side of your motorcycle. There are two marks clearly indicates "LOW" and "HIGH". The oil level should be between these two lines.




 For Himalayan after warm up take out from main stand, hold the vehicle on straight line and check the oil level in the inspection window. To keep the motorcycle straight you can just press the main stand into the level ground it will help to maintain the motorcycle in straight line.

Oil Grade and Capacity (UCE Engine)

15 W 50 API SL Grade JASO MA2  (JASO MA). Capacity 2.75Ltrs. (Initial fill)  2.5Ltrs (During Oil & Filter element replacement)

 Oil Grade and Capacity (LS410 Engine)

15 W 50 API SL Grade JASO MA2 Capacity 2.3Ltrs. (Initial fill) 2Ltrs (During oil & Filter element repentance)

Oil Change interval  - Initial 500km after that every 6000km for UCE adn 10000km for LS410.

How to Install fog lamp in your Royal Enfield

Now a days fog lamps are gaining importance in two wheeler. Many types of LED fog lamps are available in the market with reasonable price and it's very useful to ride in fogy and dust covered areas.



The main difference between normal head lights and fog lights are spreading of its beam. Fog lights are spreads wider and does not travel longer as head lamps. Head lamp beam travels longer then fog lamps. So in foggy conditions fog lamps are very useful with wide spread of beam in short distance in lower speed. 

Basic things to know before install the fog lamp
Before Install the fog lamp in your RE, first know the basic things. Your motorcycle battery is important part of the lighting, don't fix the extra loads to your poor battery it will start to give trouble. So check your battery condition and capacity. All older model 350 & 500 are equipped with 12Volt 14Ah Negative earth system. (Only self start models). Newer 350cc Electric start and Himalayan models uses 12Volt 8Ah Negative earth system, all 500cc uses 12Volt 14Ah Negative earth system. GT535 use 12Volt 8Ah.

 Choosing your lamps
 There are many types of fog LED Fog lamps available in the market as well as online. chose a good quality lamps and keep in mind that power does not more then 10 to 15Wastts, other wise it will drain the battery. Buy a good quality power cut off switch, fuse & holder, relay and wiring materials. 

LED fog lamps

Fuse holder and fuse to protect your wiring circuit (10Ah is enough)
Switch to control the power light

Relay to control the switching circuit (10Ah is enough)

Let us fix

Wiring Diagram for Fog/Auxiliary lights

 First choose proper location to to fix the lamps, do not fix too high on motorcycle it blinds the on coming traffic. Leg guard level is good. fix it with proper fasteners.

To do this work first remove the seat and fuel tank in all model, by doing this you will get plenty of space to work. In standard and classic models battery located at LH side of the vehicle, separate battery box is provided. In Thunderbird and GT its located on left side cover and In Himalayan under the rider's seat.

In above circuit check the battery its Negative terminal was connected to the frame. In Positive terminal there was to wires connected on is main wiring diagram, don't tamper it, just connect a new wire to the positive terminal and fix fuse holder into it (Please take out the fuse). 

After the fixing the fuse take the wire under the fuel tank till till fog lamp by using god quality sleeves and proper wiring ties. Connect the Positive wire to the relay Input. In relay there is fore terminal is there, out of it two terminals are used for activate the relay other two are Input and out put of the relay. (Load). So here you have to connect the battery wire to the relay's Load Input and take  another connection from the relays out put terminal and connect it  to the  fog lamp terminal. Connect other terminal of the fog lamp to the frame. Now fog lamp wiring circuit is completed.

Connecting the Power switch

Fix the fog lamp switch in handlebar in convenient location, there are two terminal in the switch connect one terminal to the Relay's power terminal, there are two power terminals in the relay another terminal has  to be connected to the frame (Earth).

Switch on the Ignition of motorcycle find the live wire of front brake or clutch switch and connect the power switch wire to it. Insert the fuse on holder, and check the lighting operation.

Working of Relay  

Relay is a simple magnetic switch it consists for terminals, out of it two terminals are connected to the battery via Power switch, another two terminals are load input and out put, which there is no electricity in the primary coil terminals load terminals are in disconnected position. As soon as switch on the power positive current passes through the  relay's coil via and build magnetic fields and pulls the contact placed top of it against the tension of a small spring. As soon as it pulls the contact the input current which was connected to the battery positive via fuse passes through the out put terminal and power goes to the fog lamps.

Joints and connectors

Proper knots

Connectors
Connecting Lugs


Notes : When you install any electrical items to your motorcycle, check the compatibility, use proper tools, connectors, seal the joints with insulator to avoid damages.
