Liquefied natural gas gasoline and diesel auto-ignite at temperatures and pressures relevant to engine design. An important part of traditional engine design is designing the cylinders, compression ratios, and fuel injectors such that pre-ignition is avoided, but at the same time as much fuel as possible can be injected, become well mixed, and still have time to complete the combustion process during the power stroke. Natural gas does not auto-ignite at pressures and temperatures relevant to traditional gasoline and diesel engine design, thus providing more flexibility in the design of a natural gas engine. Methane, the main component of natural gas, has an
Natural gas in Qatar from natural gas (79%), whilst the balance is supplied by oil. In 2009, Qatar produced of natural gas, three times the amount produced in 2000. Although the increase in natural-gas production fuels the growing natural-gas requirements of domestic industry and its GTL projects, the bulk of this increase is going towards LNG exports. Qatar's natural-gas consumption in 2009 was approximately . During 2009, Qatar exported over of natural gas, 70% of which was LNG. Qatar currently exports about of natural gas per day to the UAE and Oman through the Dolphin pipeline. In 2016, Qatar Petroleum has entered into an
