Yes. CNG has a much higher octane. Near 130 I believe. To get the full benefit and to avoid valve damage, timing is set roughly 10+ degrees advanced over standard gasoline. (you should use a timing light and check with your manufacturer). Valve damage can occur as a result of the gas still burning as it exits the exhaust due to starting the burn late. Electronic cars can use an automatic device to advance timing. On older cars, you can rotate the distributor to advance timing.

What changes should be made in petrol engine for using cng?
To adapt a petrol engine for compressed natural gas (CNG) use, modifications include installing a CNG fuel system, which consists of a high-pressure storage tank, fuel lines, and a dedicated fuel injection system. The engine's ignition timing may also need adjustment to accommodate the different combustion characteristics of CNG. Additionally, the engine's valves and valve seats may require reinforcement to handle the higher temperatures associated with CNG combustion. Finally, a conversion kit may be necessary to ensure the engine runs efficiently and safely on CNG.
Can engine be started without Sparking Plug by CNG?
No. Like the petrol-oxygen mixture, CNG also needs a spark to do the actual ignition, unlike diesel fuel which will ignite under pressure due to the heat increase of the mixture in the cylinder. So no spark, no ignition.

What is multi fuel ignition system in new petrol engine give answer in detail?
In such type of engine we can use both type of fuel (petrol and disel). And/or some other fuels like lpg, cng.
Can diesel engine be started with CNG?
no
How does a cng engine differ from a gasoline engine?
One runs on Compressed Natural Gas (CNG) and one runs on gasoline. With the right modifications, a single engine can run on both fuels.
Can a car run with the both LPG and CNG?
yes, a car with gasoline engine can run with petrol,cng, and lpg.
Can cng cars run with petrol?
No, the fuel delivery, ignition, and fuel control programs are different.
What is crdi engine in cng?
A CRDI (Common Rail Direct Injection) engine adapted for CNG (Compressed Natural Gas) utilizes a common rail system to inject CNG directly into the combustion chamber. This allows for precise control of fuel delivery and timing, improving combustion efficiency and reducing emissions. The CRDI system enhances performance and responsiveness while maintaining lower operating costs compared to traditional gasoline or diesel engines, making it a more environmentally friendly option.
What does CNG mean in regards to 5.7 engine?
Compressed natural gas
What is non- diesel exhaust?
Presumably, exhaust from a gasoline or CNG engine.
