It works by forcing fuel directly into the combustion chamber of each cylinder to mix air and gas simultaneously at the point of combustion, rather than mixing air and gas in a separate chamber like more conventional engines.
Technologies such as internal combustion engines and gas turbines will continue to improve gradually in efficiency but they are familiar and developed.
An internal combustion generator converts the gas back into electricity to provide power for the home.
When the battery is depleted (or when driven at very high speeds), the premium-gas internal combustion engine powers the car, but its fuel mileage suffers from having to shove around 400lbs of batteries.
Now, it's true that amazing gains are being made in the efficiency of internal combustion engines, both gas and diesel: direct injection, cylinder deactivation, stop-start, eco-mode throttle mapping, to name a few of the recent applied technologies.
Consider that for every BTU of coal or natural gas burned in a combustion turbine only 35 percent of that is converted into useful power.
Most of this decrease was due directly to the decreasing use of coal in power plants and the increase in combustion of clean-burning natural gas.
Cars like the Buick Encore, Fiat 500 and Lincoln MKZ, meanwhile, improve mileage through direct fuel injection, which injects gas directly into the combustion chamber in extremely precise amounts.

Post-combustion, CO2 is removed from flue gas by passing it through a liquid amine which dissolves the CO2.
Nitrogen is separated from oxygen before combustion, thereby reducing the volume of exhaust gas and making the exhaust easier to treat by preventing the formation of polluting nitrogen oxides.
At Peterhead, Shell and SSE plan to retrofit part of the existing gas power station to capture CO2 emissions after combustion.

There is technology in the works today that can economically clean coal before combustion and reduce emissions to levels rivaling the emissions of a natural gas fired plant.

The difference between turbocharging and supercharging is simple: a turbocharger boosts engine air pressure by using exhaust gas to power a turbine that pushes more air into the combustion chamber.

In SNG's case, the gas can also be compressed and used to fuel cars with internal-combustion engines.
Combustion scientist Herman Snyder, who relocated from Wisconsin, had worked at a Caterpillar subsidiary designing gas turbine engines.
One is exhaust gas recirculation, which pumps cooled exhaust back into the engine air intake, lowering the combustion temperature and reducing NOx formation.
In the mean time we just have to deal with gas, and I am sure some day a new technology will eventually replace the internal combustion engine.
The primary alternatives such as coal, oil and natural gas power plants also pose dangers to nearby residents who breathe in fine pollutants released by the combustion of these fuels.
It involves taking oxygen to the fuel not as a gas, but bound to a metal such as iron or calcium, and should in principle make combustion more efficient.
