New Arrival China TU-1J04 thermal wax actuator for industrial thermostatic water regulations mixing valve Wholesale to Russia Detail:
1. Operation Principle
The Thermostatic Wax that has been sealed in shell body induces expansion by a given temperature, and inner rubber seal part drives its handspike to move under expansion pressure to realize a transition from thermal energy into mechanical energy. The Thermostatic Wax brings an upward movement to its handspike, and automatic control of various function are realized by use of upward movement of handspike. The return of handspike is accomplished by negative load in a given returned temperature.
2. Characteristic
(1)Small body size, occupied limited space, and its size and structure may be designed in according to the location where needs to work.
(2)Temperature control is reliable and nicety
(3)No shaking and tranquilization in working condition.
(4)The element doesn’t need special maintenance.
(5)Working life is long.
3.Main Technical Parameters
(1)Handspike’s height may be confirmed by drawing and technical parameters
(2)Handspike movement is relatives to the temperature range of the element, and the effective distance range is from 1.5mm to 20 mm.
(3)Temperature control range of thermal wax actuator is between –20 ~ 230℃.
(4)Lag phenomenon is generally 1 ~ 2℃. Friction of each component part and lag of the component part temperature cause a lag phenomenon. Because there is a difference between up and down curve of traveling distance.
(5)Loading force of thermal wax actuator is difference, it depends on its’ shell size.

Engine
The long-stroke 2.0 TFSI in the Audi S3 has been developed from scratch. The only thing it has in common with its predecessor, which was named Engine of the Year five times in a row between 2005 and 2009, is its displacement of 1,984 cc (bore x stroke 82.5 x 92.8 millimeters [3.25 x 3.65 in]). The four-cylinder unit delivers a constant 380 Nm (280.27 lb-ft) of torque to the crankshaft between 1,800 and 5,500 rpm. Rated power at 5,500 rpm is 221 kW (300 hp), and the engine redlines at 6,800 rpm.
The S3 delivers impressive performance. The sprint from zero to 100 km/h (62.14 mph) is completed in 5.1 seconds when equipped with the S tronic (5.4 seconds with the manual transmission). The electronically governed top speed of 250 km/h (155.34 mph) is just a formality. The S3 with S tronic consumes on average just 6.9 liters of fuel per 100 km (manual: 7.0 liters) [34.09 and 33.60 US mpg]. This corresponds to CO2 emissions 159 (162) grams per kilometer (255.89 and 260.17 g/mile) and for models equipped with the manual transmission, an improvement of 1.5 liters compared with the previous version.
The powerful four-cylinder engine features two balance shafts rotating at twice the speed of the crankshaft for tremendous smoothness. The sound is emotion-inspiring and sporty. An electromechanical sound actuator at the bulkhead brings the engine sound to life in the cabin. The exhaust system also includes a sound flap that opens at certain engine speed ranges to give the S3 a sportily sonorous sound.
The 2.0 TFSI boasts groundbreaking solutions in many fields of technology. One of these is the additional use of indirect injection. It supplements the FSI gasoline direct injection at part load to reduce consumption and particulate emissions. FSI injection, which works at pressures up to 200 bar, is used when starting and at higher loads.
The developers achieved new degrees of freedom when it comes to filling the combustion chambers. On the exhaust side, the Audi valvelift system varies the stroke of the valves in two stages; the camshaft on the intake side can be adjusted steplessly through 30 degrees of crankshaft angle while 60 degrees of adjustment is available on the exhaust side. The compression ratio of 9.3:1 is unusually high for a turbocharged engine.
The exhaust manifold is integrated into the cylinder head, where it is bathed in coolant. This solution lowers the temperature of the exhaust and accelerates warmup following a cold start, which lowers consumption during the cold-start phase. This concept also has a positive effect on fuel consumption during sporty driving because full-load enrichment is no longer necessary. The large turbocharger is also a new development. It achieves a maximum boost pressure of up to 1.2 bar for even more spontaneous engine response. A high-performance intercooler integrated into the water circuit greatly reduces the temperature of the compressed air and thus increases the amount of air required for combustion.
With the 2.0 TFSI’s innovative thermal management system, two rotary slide valves consolidated in a single module regulate the flow of coolant. These valves ensure that the engine oil heats up to its operating temperature soon after the vehicle is started; they also maintain the coolant temperature, as per a given driving situation, between 85 and 107 degrees Celsius (185.0° F and 224.6° F). As a result — regardless of load or engine speed — the valves always strike the perfect balance between minimal friction and high thermodynamic efficiency.
The 2.0 TFSI has been designed specifically for use in the new Audi S3. Pistons with stronger bolts and new rings plus reinforced connecting rods with new mounts transfer the power to the crankshaft. The gray cast iron crankcase has been reinforced at the main bearing seats and the main bearing cover. The cylinder head is made of a new, particularly lightweight aluminum-silicon alloy characterized by high strength and temperature resistance.
An innovative coating on the piston skirts and mounting the balance shafts in roller bearings keep internal friction low. The regulated oil pump only consumes as much energy as is necessary for the current driving situation.
Despite its complexity and the high performance, the new 2.0 TFSI weighs just 148 kilograms (326.28 lb) — more than five kilograms (11.02 lb) less than the previous engine. The dimensions are compact: 603 millimeters (23.74 in) long, 678 millimeters (26.29 in) wide and 664 millimeters (26.14 in) high.
