摘要： A supplemental fuel system includes a fuel mixer. The fuel mixer includes a nozzle and a stem. The nozzle is configured to be positioned within a conduit of an air supply system for a compression-ignition engine. The nozzle has a body defining a first inlet positioned at a first nozzle end thereof, an outlet positioned at a second nozzle end thereof, a second inlet positioned between the first nozzle end and the second nozzle end, and a nozzle passage extending from the first nozzle end to the second nozzle end that is configured to receive air flowing through the conduit. The stem has a first stem end interfacing with the second inlet. The stem is configured to extend through a wall of the conduit such that a second stem end is positioned outside of the conduit.

摘要： Methods and systems for providing exhaust gas recirculation to a two stroke opposed piston diesel engine are described. In one example, high and low pressure exhaust gas recirculation systems may be activated or deactivated in response to exhaust gas hydrocarbon concentration and particulate matter flow rate from the engine. In addition, operation of the low and high pressure exhaust gas recirculation systems may be responsive to an operating state of a supercharger compressor.

摘要： A cast-aluminum engine block for a compression-ignition internal combustion engine includes a plurality of cylinders that are disposed in an in-line arrangement. The engine block includes a top portion including a top deck and a bottom portion including a plurality of main bearings that are disposed to support journals of a crankshaft. An integrated flow channel is formed between the second end and the last cylinder and proximal to the top deck, and is a continuous channel that passes from the first side to the second side through the portion of the engine block between the second end and the last cylinder and proximal to the top deck. A coolant passageway is disposed in the engine block between the integrated flow channel and the last cylinder, and is oriented parallel to the elevation axis.

摘要： A compression-ignition low octane gasoline engine. The engine uses low octane gasoline and a compression-ignition method, does not require a spark plug, and compared with ordinary gasoline engines, increases thermal efficiency by approximately 40% and reduces green-house effects caused by emissions by approximately 45%. The “compression-ignition” of the low octane gasoline engine is a diffusion charge compression-ignition, differing from a homogeneous charge compression-ignition. The compression ratio in a cylinder can be 14 to 22, while an ordinary gasoline engine has a compression ratio of 7 to 11. The low octane gasoline engine has a simple structure, easy combustion control, a low noise level, and a low failure rate. As the low octane gasoline can be free of aromatic hydrocarbons, and not require the addition of antiknock agents such as MTBE and MMT, the present novel gasoline engine is a highly efficient, clean, and environmentally friendly internal combustion engine.

摘要： An engine-driven electricity generation system can selectively use diesel and LNG as fuel by recycling a diesel engine from a scrapped vehicle and heats intake air with an electric heater to start an engine using LNG and then heats the intake air using heat from a high-temperature exhaust gas after starting the engine, thereby accelerating ignition of LNG.

摘要： A linear reciprocating engine may include a cylinder having a first combustion chamber at one end and a second combustion chamber at an opposing end, first and second cylinder heads located at an end of the first and second combustion chambers, respectively, and a double-faced piston slidably mounted within the cylinder. The engine may further include a first piston rod portion extending from a first face of the double-faced piston through the first combustion chamber, and a second piston rod portion extending from a second face of the piston through the second combustion chamber. Passageways in the piston rod portions may be configured to communicate gases between the combustion chamber and a location outside the cylinder and configured to prevent gases from being exchanged between the cylinder and a location outside the cylinder via a path that crosses both face of the piston.

摘要： A piston assembly comprises a piston body, a connecting rod, and a wrist pin. The piston body includes a pair of first cross bores presenting a piston sliding surface. The connecting rod includes a second cross bore presenting a rod sliding surface which is axially aligned with the first cross bores of the piston body. A wrist pin is disposed in the aligned cross bores and couples the piston body to the connecting rod. The wrist pin also presents a pin sliding surface facing the rod sliding surface and the piston sliding surfaces. A coating is applied to at least one of the sliding surfaces, such as by dipping, brushing, atomizing, spraying, printing, or screen printing. The coating includes a polymer matrix, such as polyamide imide (PAI), and hard particles, such as Fe2O3, disposed throughout the polymer matrix. The hard particles have a hardness of at least 600 HV/0.5.

摘要： Methods for cleaning gas sensors used in an exhaust gas system are provided. The exhaust gas system can include an exhaust gas stream supplied by an exhaust gas source through an exhaust gas conduit, and a gas sensor having a sampling end disposed within the exhaust gas conduit. The methods can include positioning at least one glow plug proximate the gas sensor; and activating the at least one glow plug such that exhaust gas deposits accumulated on the gas sensor sampling end are removed. The methods can optionally further comprise one or more of determining a glow plug activation interval and determining a glow plug activation duration. Systems for performing the disclosed methods are also provided.
