Compressed natural gas (CNG) is a fuel gas mainly composed of methane (CH 4), compressed to less than 1% of the volume it occupies at standard atmospheric pressure.It is stored and distributed in hard containers at a pressure of 20–25 megapascals (2,900–3,600 psi; 200–250 bar), usually in cylindrical or spherical shapes.
The 4HF1-CNG is a CNG engine of 4.334 L capacity (as based on direct injection diesel engine) with non-contact ignition system. Peak torque is 323 Nm, peak power is 120 PS (88 kW) at 1,500 rpm. Peak torque is 323 Nm, peak power is 120 PS (88 kW) at 1,500 rpm.
The time to fill a CNG tank varies greatly depending on the station. Home refuels typically fill at about 1 kg/h (0.4 GGE/h). At gas stations, where the pressure is greatly higher, it is possible to refill a 25 kg (10 GGE) tank in 5–10 minutes. Also, because of the lower energy density, the CNG range is lower compared to LNG.
LPG has a typical specific calorific value of 46.1 MJ/kg compared with 42.5 MJ/kg for fuel oil and 43.5 MJ/kg for premium grade petrol (gasoline). [14] However, its energy density per volume unit of 26 MJ/L is lower than either that of petrol or fuel oil, as its relative density is lower (about 0.5–0.58 kg/L, compared to 0.71–0.77 kg/L for ...
The heating value depends on the source of gas that is used and the process that is used to liquefy the gas. The range of heating value can span ±10 to 15 percent. A typical value of the higher heating value of LNG is approximately 50 MJ/kg or 21,500 BTU/lb. [2] A typical value of the lower heating value of LNG is 45 MJ/kg or 19,350 BTU/lb.
For engines, the facelifted Ertiga received the new K15C Dualjet 1.5-litre MHEV petrol engine and a new compressed natural gas (CNG) engine. [47] The model surpassed 10 lakh total sales figure in February 2024 [ 48 ] and was the top selling car in October 2024 for the second month running with numbers of 18,785 units.

A gas cylinder quad, also known as a gas cylinder bundle, is a group of high pressure cylinders mounted on a transport and storage frame. There are commonly 16 cylinders, each of about 50 litres capacity mounted upright in four rows of four, on a square base with a square plan frame with lifting points on top and may have fork-lift slots in the ...
