A system and a method of controlling the temperature of fuel injected into combustion engines, which provides a reduced amount of fuel injected into engines propelled with either pure gasoline or ethanol or any bi-fuel mixture by precisely controlling the amount of heat supplied to the fuel.

The present invention provides a fuel supply system, for an eco-friendly ship, which selectively uses an existing fuel and an ammonia fuel or uses a mixture thereof as a fuel for a propulsion engine and a power generation engine of a ship so as to follow ship greenhouse gas regulations to be reinforced in phases at major points until 2050.

A method of improving fuel efficiency in a diesel fuel internal combustion engine on a vehicle includes providing a combustion system including a fuel tank, an engine, and a fuel line disposed between the fuel tank and the engine. A heat exchanger is positioned on the fuel line between the fuel tank and the engine. Working thermal fluid is passed from a reservoir through the heat exchanger while fuel is passed through the heat exchanger, increasing the temperature of the fuel passing through the heat exchanger. A vibration isolation mount is installed between the heat exchanger and the vehicle, thereby reducing vibration of the heat exchanger during use of the vehicle. Heated fuel from the heat exchanger is delivered to the engine, improving the fuel efficiency of the engine by burning the heated fuel.

A method to control the combustion of a compression ignition engine having the steps of: establishing, for each combustion cycle, a fuel quantity to be injected into the cylinder; injecting a first fraction of the fuel quantity; heating a second fraction of the fuel quantity, which is equal to the remaining fraction of the fuel quantity, to an injection temperature higher than 100° C.; injecting the second fraction of the fuel quantity heated to the injection temperature into the cylinder at the end of the compression stroke and at no more than 60° from the top dead centre; and decreasing the injection temperature and the ratio between the second fraction and the first fraction as the internal combustion engine increases and as the rotation speed of the internal combustion engine increases.

The present invention relates to a combination of components suitable to break down liquid fuels into short chain molecules and gaseous states of matter by heating and pressurizing the combustible/flammable liquids to the point where they phase change into a supercritical fluid, then releasing some fluid as needed into a vapor accumulation tank that has a lower pressure. This subsequent drop in pressure phase changes the fluid from a supercritical state into a consistent and safe gaseous state. From there, the fuel can be delivered to the engine via direct injectors, gaseous fuel carburetors, or a regulating valve such as a needle valve. Because gaseous fuels readily homogenize with intake air and oxidizers, the present invention allows any engine to cleanly, reliably, and consistent use any fuel without adjustment. This allows any engine to run off any combustible liquid, in effect creating the ultimate multifuel system.
