摘要:
A fluid mixing device that includes a housing having a fuel inlet and at least one primary orifice positioned at the inlet, wherein the at least one orifice configured to disperse a stream of fuel into a plurality of fuel droplets. The plurality of fuel droplets contact a fuel impingement surface to break up the plurality of fuel droplets into a plurality of smaller secondary droplets and create a thin film of secondary droplets on the impingement surface. At least one pressurized air channel delivers an airflow into contact with the secondary droplets. The secondary droplets pass through a plurality of secondary outlet orifices to exit the housing. A size of the plurality of secondary droplets is reduced when passing out of the plurality of secondary orifices.

摘要:
A fuel injection device injects fuel per each cylinder in an engine having a plurality of cylinders #1 and #2. At a time of engine actuation, start timings of fuel injections are shifted per each cylinder and times within one rotation of a crankshaft is set as the injection start timings for all cylinders. At least the initial fuel injection is performed before cylinder discrimination.
摘要:
A chainsaw includes: an engine unit; a fuel supplying device configured to supply fuel to the engine unit; and an engine chamber defining portion defining an engine chamber therein. The engine unit includes: a cylinder unit housing a piston therein; a crankshaft configured to be driven by the piston; and a crank case configured to support the cylinder unit and house the crankshaft therein. The cylinder unit is accommodated in the engine chamber. The engine chamber defining portion has a partitioning portion interposed between the cylinder unit and the fuel supplying device and is formed with a first engine chamber venthole and a second engine chamber venthole adjacent to the cylinder unit for achieving ventilation between the engine chamber and atmosphere.

A method for determining cylinder blow-through air via engine volumetric efficiency is disclosed. In one example, the method provides a way to adjust cylinder blow-through to promote and control a reaction in an exhaust after treatment device. The approach may simplify cylinder blow-through calculations and improve engine emissions via providing improved control of constituents reaching an exhaust after treatment device.
摘要:
A housing for an engine is provided. The housing includes an intake manifold configured to supply air to at least one chamber defined within the housing, a fuel port configured to supply fuel to the at least one chamber, and a compression control port configured to control at least one of a pressure and a volume of a fuel-air mixture in the at least one chamber during a compression cycle of the engine. The compression control port includes a passage defined through the housing, and at least one valve disposed in the passage and configured to control a flow through the passage.
摘要:
When a start-up failure occurs wherein an internal combustion engine equipped with a variable valve device does not transition to complete combustion before a first prescribed period α elapses from the start of cranking in conjunction with fuel injection, a control unit for the internal combustion engine executes a start-up failure process addressing a state wherein the valve timing is different from a specific timing.
摘要:
An intake apparatus of an engine provided with a fuel supply device for supplying fuel into an intake passage. A guide body is disposed in the intake passage located downstream from the fuel supply device, and the guide body may have at least one hole. The volume ratio of the guide body relative to the intake passage range and the volume ratio of the total holes relative to the guide body are ranged in the preferable volume percent.
