The forced recirculation mixer (1) consists of a stirring enclosure (5) whose internal cavity forms a recirculation loop (6) in which circulates a homogeneous gas mixture (4) formed by a gas (3) to be mixed and a vaporizable liquid (2) respectively introduced into that loop (6) via a gas inlet duct (7) and a liquid injection nozzle (9), gas drawing-off means (12) being capable of withdrawing a homogeneous gas mixture (4) from the stirring enclosure (5) via a mixture draw-off duct (11) and a stirring turbine (13) driven by a turbine motor (28) forcing the homogeneous gas mixture (4) to circulate in the recirculation loop (6).

Disclosed are a high pressure fuel pump and a liquid petroleum direct injection system including the same. The high pressure fuel pump includes a body having an intake port and an exhaust port, and provided therein with a pressing device configured to press a portion of fuel at a high pressure, a spill valve coupled to one side of the body to control a supply flow rate and exhaust pressure of the fuel, and a cover coupled to an upper portion of the body and having a recovery port for recovering a portion of the fuel to a bombe. The cover has a dome shape that is convex upward. The cover collects gaseous fuel generated by heat of an engine when the engine is turned off after driving, that is, collects vapor to recover the vapor to the bombe, thereby improving the restartability.

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.

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.

A rotary engine includes an insert having a pilot subchamber defined therein and communicating with the internal cavity of the engine. A pilot fuel injector has a tip in communication with the pilot subchamber. An ignition element extends into an element cavity defined through the insert adjacent the pilot subchamber. The element cavity is in communication with the pilot subchamber through a communication opening defined in the insert between the element cavity and the pilot subchamber. The communication opening is smaller than a portion of the ignition element adjacent the communication opening such as to prevent the portion of the ignition element from completely passing through the communication opening upon breaking off of the portion of the ignition element from a remainder of the ignition element. An outer body for a rotary engine and a method of combusting fuel in a rotary engine are also provided.

A thermal energy power device is disclosed. A gasification reactor is arranged on a TDC of a cylinder bulk of an internal combustion engine, wherein the gasification reactor includes gasifying plates (19) and gas holes (23). The gasifying plates are arranged with gaps on the TDC of the cylinder. The gas holes (23) are distributed evenly, in an array, or in a staggered manner on the gasifying plate (19). A cylinder head above the gasification reactor is provided with an atomizer (12). Heat absorption plates (26) are arranged inside the exhaust passage in parallel with an air flow direction. The heat absorption plates (26) absorb thermal energy of exhaust gas and transfer the thermal energy to the gasification reactor. The internal combustion engine is wrapped with an insulation layer. An added working stroke enables the temperature of the cylinder bulk to be lowered. The compression ratio is high. After being filtered by a cooler and a liquid storage tank, the discharged exhaust gas is more environmentally friendly than existing engines. After the temperature of the cylinder bulk is lowered, the discharged exhaust gas is filtered by the cooler and the liquid storage tank without noise. A working stroke is added, and the thermal energy utilization rate increases by 20%-95%. Thermal energy utilization is performed directly on the exhaust passage, and a heat dissipation water tank is not required.
