CNG KITS FITTING PROCESS
The first query that is often raised in respect to CNG kits is the differentiation between open and closed-loop kits. The most basic difference between the two is that of absence or presence of an MPFI (Multi-Point Fuel Injector) fuel injection system in petrol-based cars. In the open-loop CNG kit, no automatic calculation can be made for the amount of gas that the car will require. Therefore, regular adjustments will have to be made from time to time i.e. the CNG kit will have to be tuned at regular intervals. The closed-loop CNG kits are equipped with sensors that regulate the gas injection level on their own. Hence, cars incorporated with closed-loop have better fuel efficiency, acceleration, and are free from the requirement of any kind of tuning. The basic cost difference between the two is not more than 7000-10000 Indian Rupees.
Next comes the CNG kit working principle and the significance of lambda in it. So what exactly is a lambda? Well, lambda is a device that closely resembles the timing advancer that is fitted closely with an open-loop CNG kit. It is the presence of this device in the gas system that turns an open-loop system into a closed one. So, is it the only level of classification for the CNG kits? No, it is not, there is one more level of categorization that is used with respect to CNG kits.
In the other system of classification to there are two types of CNG kits. The first one is the venture kit that injects a fixed amount of gas into the vehicle engine with respect to the throttle input. Their work resembles much with the carburetors. Also, these are cheaper with a much simple design and concept. These kits can be used in all kinds of automobiles whether they use carburetor-based mills or the fuel-injection technique. The buyer can also couple these with Electronic Control Units (ECUs) if they want.
