Description

The engine for improving the method for engine efficiency and matching with the method

Technical field

The present invention relates to technical field of engines, more particularly to a kind of method that can improve engine efficiency and with Corresponding energy-saving efficient engine.

Background technology

Engine be it is a kind of can be the machine that can be converted into mechanical energy of other forms, it experienced steam engine, external combustion Three developing stage of machine and internal combustion engine.The species of internal combustion engine is very various, and common gasoline engine, diesel engine are typical internal combustions Machine.But, because gasoline is different thus all different in the operation principle and structure of engine with the property of diesel oil.

First, the operation principle of gasoline engine is that air and gasoline are mixed into good gaseous mixture in certain proportion, is being entered Gas stroke is inhaled into cylinder, the compressed ignition of gaseous mixture and produces heat energy, and the gas of HTHP acts on top land, Piston is promoted to do reciprocating linear motion, by connecting rod, the external output mechanical energy of crankshaft-flywheel mechanism.It is with four-stroke gasoline engine Example, is one working cycles of completion in suction stroke, compression travel, working stroke and instroke.

1) suction stroke

Piston moves to lower dead center under the drive of bent axle by top dead centre.Now IO Intake Valve Opens, exhaust valve closing, bent axle turns It is dynamic 180 °.In piston moving process, cylinder volume gradually increases, and cylinder charge pressure is gradually lowered to pa, cylinder from pr The gaseous mixture of the certain vacuum of interior formation, air and gasoline is inhaled into cylinder by inlet valve, and is further mixed in cylinder Conjunction forms combustion mixture.Because gas handling system has resistance, cylinder charge pressure is less than atmospheric pressure 0p, i.e. pa= (0.80~0.90) 0p.Into the temperature of the combustion mixture in cylinder, due to air inlet pipe, cylinder wall, piston top, valve and combustion Burn the heating of hot parts such as locular wall and with the mixing of residual gas and be increased to 340~400K.

2) compression travel

During compression travel, inlet and outlet door is simultaneously closed off.Piston is moved from lower dead center to top dead centre, 180 ° of crank rotation.It is living When moving beyond the Great Wall, swept volume is gradually reduced, and the compressed rear pressure and temperature of gaseous mixture is constantly raised in cylinder, reaches compression terminal When, up to 800~2000kPa, temperature is up to 600~750K for its pressure p c.

3) working stroke

When the piston is near the top dead centre, by spark ignitor combustion mixture, mixture combustion discharges substantial amounts of heat energy, The pressure and temperature of cylinder charge is set to improve rapidly.Maximum pressure pZ is up to 3000~6000kPa for burning, temperature TZ up to 2200~ 2800K.The combustion gas of HTHP promotes piston to be moved to lower dead center from top dead centre, and externally exports machine by toggle Tool energy.As piston is moved down, cylinder volume increases, and gas pressure and temperature are gradually reduced, and when reaching b points, its pressure is down to 300 ~500kPa, temperature is down to 1200~1500K.In working stroke, inlet valve, exhaust valve are turned off, 180 ° of crank rotation.

4) instroke

During instroke, exhauxt valve opens, inlet valve is still closed, and piston is moved from lower dead center to top dead centre, and bent axle turns It is dynamic 180 °.During exhauxt valve opens, on the one hand the waste gas after burning discharge under the effect of cylinder inside and outside differential pressure to outside cylinder, on the other hand Acted on by the exclusion of piston and being vented to outside cylinder.Due to the drag effect of gas extraction system, the pressure for being vented terminal r points is a little higher than big Atmospheric pressure, i.e. pr=(1.05~1.20) p0.Exhaust outlet temperature Tr=900~1100K.When piston movement is to top dead centre, combustion The waste gas that a constant volume is still left in burning room cannot be discharged, and this portion is residual gas.

2nd, the operation principle of diesel engine is that as gasoline engine, each working cycles is also by suction stroke, compressed line Journey, working stroke and instroke composition.Because diesel engine makees fuel with diesel oil, compared with gasoline, diesel oil autoignition temperature is low, glutinous Degree is big to be difficult evaporation, thus diesel engine using compression terminal involuntary ignition, and its course of work and system architecture are with gasoline engine It is different.

1) suction stroke

Working medium into cylinder is pure air.Because diesel engine air inlet system resistance is smaller, air inlet terminal pressure pa= (0.85~0.95) p0 is higher than gasoline engine.Air inlet outlet temperature Ta=300~340K is lower than gasoline engine.

2) compression travel

Because the working medium compressed is pure air, therefore the compression ratio of diesel engine is (generally ε=16~22) higher than gasoline engine. The pressure for compressing terminal is 3000~5000kPa, and the temperature for compressing terminal is 750~1000K, substantially exceeds the spontaneous combustion temperature of diesel oil Degree (about 520K).

3) working stroke

When compression travel is close to end of a period, under high-pressure oil pump effect, diesel oil is passed through into oil spout with the high pressure of 10MPa or so Device is sprayed into cylinder chamber, burning of being voluntarily under fire immediately after mixing with air in a short period of time.The pressure of cylinder charge Power rapidly rises, up to 5000~9000kPa, and maximum temperature is up to 1800~2000K.Due to diesel engine be pressured contracting voluntarily Fire burning, therefore diesel engine is called compression ignition engine.

4) instroke

The exhaust of diesel engine is essentially identical with gasoline engine, and simply delivery temperature is lower than gasoline engine.General Tr=700~ 900K.For single-cylinder engine, its rotating speed is uneven, engine roughness, and vibration is big.Because four strokes Middle only one of which stroke is acting, and other three strokes are that consumption power is the stroke prepared.In order to solve this Problem, flywheel must have sufficiently large rotary inertia, can so cause whole engine quality and size to increase again.Using many Cylinder engine can make up above-mentioned deficiency, but, while there is also complex structure, the problems such as technology difficulty is big, technical requirements are high.

Also, internal combustion engine common at present also has that energy use efficiency is not high, shows as：

1st, engine piston reach top dead centre, compression ratio reach a timing point combustion or compression ignition (diesel engine use compression ignition skill Art), not only just combustion phase energy is not utilized effectively, and increases cylinder pressure, influences the service life of engine；

2nd, because fuel quality is different, cylinder fuel optimum compression ratio is different, if it is desired to use the car of high-grade gasoline When imprudence uses low grade oil product, detonation may be shifted to an earlier date and produce pinking, engine is caused to damage.

Therefore, how by technological improvement, improving the energy use efficiency of internal combustion engine, reduce energy resource consumption and environment is dirty Dye, is all the time problem that people pay special attention to.
