Description
Affiliated field
The invention belongs to the efficiency improvement field of motor.
Background technique
Conventional engines variable capacity explosive motors such as (comprise two circulations and four) circulating by improve the intake efficiency of motor, volumetric efficiency, fuel mixing efficiency improve the thermal efficiency of motor.
But it is in practice, as shown in the prior art, always conflicting to the acquisition of this three.
Reason is that conventional engines to move to lower dead center with piston in cylinder, to produce negative pressure fresh air (or mixed gas) is sucked cylinder, when obtaining higher fuel mix efficiency when adopting special intake duct or adapt to the combustion system of motor, intake efficiency and the volumetric efficiency of motor can be reduced further, even if when adopting turbosupercharger or other pressurized machines to engine booster, same meeting is because absorb amount of heat at the fresh air (or mixed gas) of engine charge circulation suction from cylinder wall and chamber wall and expand, which reduces the fresh air (or mixed gas) entering cylinder, and then reduction volumetric efficiency.
The petrol engine of injected petrol in cylinder is such as adopted usually to take in engine charge hole or/and intake duct place guides the measure of the flowing of air-flow, obtain the intake swirl needed in intake process cylinder, to adapt to the combustion system of motor, this also just inevitably affects the intake efficiency of motor.
Adopt the diesel engine of high pressure co-rail system to have the mixing efficiency of higher intake efficiency, volumetric efficiency, fuel, also there is lower pollutant emission, but adopt high pressure co-rail system to add the cost of motor.
If what can provide a kind of low cost has higher intake efficiency, volumetric efficiency, the mixing efficiency of fuel and the engine system of lower pollutant emission and equipment, will be the tremendous contribution to prior art.
Summary of the invention

In an engine operating cycle, a part of fresh air (or mixed gas) in combined supercharging device in the present invention enters engine cylinder on engine charge circulation rank, fresh air (or mixed gas) in piston type pneumatic compressor pump enters engine cylinder when engine compression cycles starts or after starting and enter engine cylinder completely at the end of engine compression cycles or before terminating, when the piston of piston in piston type pneumatic compressor pump in engine cylinder moves to the top dead center of engine cylinder or move to the top dead center that budc moves to piston type pneumatic compressor pump.
In technique scheme, when the internal diameter of the engine cylinder in the present invention is identical with the internal diameter of conventional engines cylinder, piston stroke in engine cylinder in the present invention is identical with the piston stroke in conventional engines cylinder, when air pressure when air pressure when the piston of motor in the present invention in engine compression cycles cylinder moves to top dead center or engine ignition in firing chamber and the piston of conventional engines in compression cycle cylinder move to top dead center or engine ignition in firing chamber is identical, combustion chamber volume in engine cylinder of the present invention is greater than the combustion chamber volume in conventional engines cylinder.
In technique scheme, outside the pump housing of piston type pneumatic compressor pump and the suction tude in connection piston type pneumatic compressor pump air outlet hole and combustion chamber charge hole, cooling passage is set, heat in gas farthest can be taken away by carrying out cooling to the gas after compression, when making the gas in piston type pneumatic compressor pump enter firing chamber, the temperature of gas is lower, this guarantees gas temperature when engine compression cycles piston moves to top dead center or engine ignition in firing chamber in normal range (NR), be unlikely when producing pinking or fuel combustion because the amount of the pollutant of high temperature generation increases.
In technique scheme, due in the cylinder block of engine operation piston type pneumatic compressor pump and the running temperature of piston lower (even lower than ambient air temperature), by piston type pneumatic compressor pump to engine cylinder pumping fresh air (or mixed gas), decrease and reduce the amount of the fresh air (or mixed gas) that enter engine cylinder when inhalation cycle fresh air (or mixed gas) enters cylinder because of absorbing heat from cylinder wall and chamber wall relative to above-mentioned conventional engines, this provides for improved the volumetric efficiency of motor.Use combined supercharging device to carry out supercharging to engine cylinder and piston type pneumatic compressor pump simultaneously, this provides for improved the intake efficiency of motor and piston type pneumatic compressor pump.When motor runs, the piston of fresh air (or mixed gas) in piston type pneumatic compressor pump in piston type pneumatic compressor pump is squeezed into engine cylinder when top dead center moves, owing to being that the mode clamp-oned enters engine cylinder, fresh air (or mixed gas) forms high velocity air in firing chamber fresh air (or mixed gas) air inlet position be communicated with piston type pneumatic compressor pump air outlet hole or firing chamber, swiftly flowing gas better can mix with fuel, this provides for improved the mixing efficiency of fuel.
In technique scheme, when one or more piston type pneumatic compressor pump is when an engine operating cycle is to multiple engine cylinder conveying fresh air (or mixed gas), what the actual displacement of motor was greater than all engine cylinders and piston type pneumatic compressor pump scans out discharge capacity (amount of the air an operation cycle piston to move to the normal temperature and pressure that top dead center extrudes from the lower dead center of engine cylinder and piston type pneumatic compressor pump) sum, be filled with more fresh air (mixed gas) at an engine cylinder simultaneously, just can burn more fuel in an engine cylinder, this reduces the cost produced required for specific power (power per liter).
