Brief introduction: Model SKY2102-VII gasoline octane number determination machine is used to determine the gasoline octane number. The instrument is composed of a standard single cylinder engine with variable compression ratio and a measurement and control system based on industrial computer. It conforms to GB/T 503, GB/T 5487, ASTM D2700, ASTM D2699 and other standards. The main advantage of the instrument is that the repeatability of the compression ratio test is less than 0.2/R octane number.Suitable for large oil refining industry, compared with similar imported instruments have a high cost performance.Equipped with ice tower and three - phase stabilized power supply. Features: Control case new industrial design, metal paint, beautiful and durable. 17 "industrial control computer touch screen design, based on WIN7 system new software operation interface, function options at a glance, easy and fast operation. The software program with independent knowledge product has built-in work curve. The use of automatic computer compensation for atmospheric pressure, the configuration of air pressure compensation curve, eliminating the trouble of manual table. Two - stage oil filter, clean oil, effective lubrication and cooling, ensure efficient operation of the engine, extend the service life. The combination of pulley, fast and easy to achieve the research method and motor method switch. New size mixed heater, research method and motor method switch without disassembly. The large wire system cable connection, neat and beautiful, strong and weak electricity separation, solve the electromagnetic interference, data transmission is stable and reliable. Engine ignition advance Angle real-time display, convenient condition detection, motor method with compression ratio automatically corresponding. Stainless steel cooling water tower, avoid corrosion of inner circulation channel, improve the cooling effect of cylinder liner. Low inlet configuration: professional 2-4 ℃ with double round robin LengBingDa control, constant temperature and humidity, the mixture of oil and gas atomization, improve combustion efficiency, reduce the carbon deposition, improve data stability and repeatability. Low power cooling cycle machine, water tank capacity of 60 l, or water pressure: 0.2 ~ 0.4 Mpa, working temperature: 15 ~ 25 ℃. With the engine crankcase pressure monitoring, at any time to understand the piston, piston ring and cylinder liner sealing performance, at any time to grasp the engine operating conditions, more intuitive real-time understanding of whether the instrument test conditions are stable. Exhaust configuration: the instrument is equipped with a muffler. Ignition system: hall ignition (magnetic induction ignition) patented technology, repeatability less than 0.2/R octane number. Magnetic-induced detonation sensor, stable detonation signal, improve the sensitivity and anti-interference ability of detonation signal display, provide favorable conditions for subsequent signal conversion and processing, and normalize and interchangeable detonation signal through signal transmission and setting. The use of laser displacement sensor, direct detection of micro changes in cylinder height, to meet the requirements of high precision and thermal stability, cylinder height set upper and lower limit protection, safe and reliable. Lubrication system: equipped with lubricating oil auxiliary preheating function, auxiliary heating and temperature control of engine lubricating oil, greatly accelerate the preheating speed, so that the instrument quickly into the test condition, to meet the test conditions. Oil system: the new configuration of four parallel storage tanks, float, needle valve and level pipe in their own independent space, not to interfere with each other when adjusting. Optional fourth oil cup refrigeration, suitable for light component oil test. Safety system: set emergency stop function. Control technology: with data collection, automatic calculation, automatic control, automatic table lookup, printing and prompts and other functions. The system built-in preset "octane number ~ compression ratio" work curve, to achieve automatic table lookup function, wide compatibility, easy to upgrade. Real-time display of engine operating pressure and negative pressure gauge. Engine power indicator: digital screen display. - scroll save 300 test records, provide text (.txt) and spreadsheet (.xls) file saving function. Automatic recording boot and test cumulative time, automatic display maintenance tips. Technical parameters: Test method: support compression ratio method and interpolation method oil evaluation operation, can meet the national standard requirements. Test standard: the instrument has two kinds of test methods: motor method and research method. Testing range: 40-120 octane number Cylinder diameter: 82.55mm (3.250in) Piston stroke: 114.3mm (4.50in) Cylinder capacity: 0.61L (37.33in3) Valve clearance: inlet valve 0.20mm exhaust valve 0.20 0.025mm Spark plug clearance: 0.51 0.13mm Compression ratio range: 4:1 ~ 18:1, compression ratio can be automatically and manually controlled, with deceleration self-locking function. Engine speed: motor method (900 9) r/min; Study method (600 6) r/min Lubricating oil pressure: 172 ~ 207Kpa Low oil temperature: 57-8 ℃ have oil auxiliary preheating function Low cylinder jacket coolant temperature: 100 + 1.5 ℃ Low motor method of mixture temperature: 149 + / - 1 ℃ Low inlet temperature motor method: 38 plus or minus 2.8 ℃ Low study inlet temperature: 52 + / - 1 ℃ (under standard atmospheric pressure) with the atmospheric pressure correction, remain within + / - 1 ℃ Low ignition advance Angle (real-time display) : the motor method epsilon 5.0 (plus or minus 1.5 ° 26) based on computer automatically adjust the compression ratio Method (13 °) fixed Power supply voltage: 380 10%VAC, 50 1Hz220 10%VAC, 50 1Hz Host power: 12KW accessories power: 7KW Instrument size: 1700 wide * 900 deep * 1400 high (mm) Overall quality: 900kg
