Introduction to Sterling Engine

1. Stirling engine is a kind of external combustion engine. The Stirling engine was invented by British physicist Robert Stirling in 1816, so it was named "String Engine".

2. Stirling engine is a closed-cycle heat recovery engine that can use a variety of fuels as energy; or hot air engine. Stirling engine is another kind of reciprocating power machinery in addition to steam engine and internal combustion engine; Stirling engine can be used not only as a prime motor, but also as a chiller, heat pump or pressure generator.

3. The principle of Sterling engine is to use the energy transformation brought about by the temperature difference. Heat expansion and cold contraction, and then quickly dissipate the heat in the heated place in time. This cycle consists of two isothermal processes and two constant volume recovery processes, which belongs to a generalized Carnot cycle. The key to realizing the Stirling cycle is to achieve backheating.

4. Advantages of Stirling engine Compared with internal combustion engine, Stirling engine has very obvious advantages. It is suitable for all kinds of liquid and solid fuels, even solar energy, low noise, avoids the process of internal combustion engine explosion and intermittent combustion, is not affected by air pressure, and is suitable for areas with high sea level.

What's wrong with Cummins m11 burning blue smoke

The combustible mixture is too thick. There is too much oil in the engine fuel. The piston ring or crankshaft oil seal is poorly sealed. There is moisture in the fuel. Spark plug poor air filter is too dirty, troubleshooting elimination, inspection and diagnosis of too thick combustible mixed gas, should focus on checking the carburetor and air filter.

The M11 model is characterized by large power and small size, which means that its material must be excellent, so the maintenance should be more careful than other engines.

What is the number of flywheel teeth of Cummins m11

The number of flywheel teeth of Chongqing Cummins engine is 138 teeth. The number of teeth of the Cummins flywheel gear ring is 138 teeth with 9 or 11 teeth of the starter.

between 42. According to the official website of Melida Stella Bicycle, the number of flywheel teeth of Melida Stella 1000 series products is generally between 36 and 42. These models usually adopt a 3-piece front tooth plate and a 9-10-speed rear transmission.

In general, the tooth plate is 52 or 53 teeth, and the compressed tooth plate is 50.

One is a motor with 11 teeth, and there are also 6112-108 teeth, Cummins 6BT-173 teeth 6CT-195 teeth. Anyway, I can't finish it for a while. The models I mentioned are all without supercharging. In addition, the number of teeth will also affect the size of the flywheel, and the size of the flywheel will seriously affect the power of the engine.

The capacity of the fuel tank is 35L, and the continuous working time is 12 hours. The flywheel is one of the important parts of the engine, which can store the kinetic energy of the engine and smoothly output it to the transmission system. The number of teeth on the flywheel refers to the number of teeth on the flywheel, which matches the gears in the transmission system, so that the engine can transmit power smoothly.

The minimum number of flywheel teeth in the flywheel group of the road bike is 11; the maximum number of flywheel teeth is mostly 23 or 25, and occasionally there are climbing wheels with 27 teeth; the minimum number of flywheel teeth in the flywheel group of the mountain bike is 12; the maximum number of flywheel teeth is mostly 28.

What is the reason why the Cummins qsm11 engine burns oil

Because the domestic fuel quality is not synchronized with international standards, it is very easy to form a large amount of volume in the combustion chamber during the engine operation. Carbon, carbon accumulation is the root cause of various problems in the engine.

During driving, the cooling system lacks water, and the water temperature report and other systems fail, causing the engine to overheat. Insufficient lubricating oil or dirty failure of lubricating oil leads to poor lubrication. The impeller of the supercharger is damaged, and the metal object sucks the cylinder after the residual blade inlet cylinder or the supercharger and the intake and exhaust valve spring are broken.

Then there are problems in use, such as adding too much oil, and overheating or overcooling of the machine will cause the loss of oil. If you are sureThere is no problem in the use of your engine. You can consider a few points: External leakage: Is there oil leakage near the crankcase breathing tube?

What is the reason why the fuel tank of the Cummins 210 engine is put into the diesel

Possible reasons: the fuel nozzle is stuck, the atomization is poor, the combustion is incomplete, and the unburned diesel will enter the oil sap along the cylinder wall. Slot. ( Overhaul the fuel injector). Connect the plate injection pump, the plunger leaks, and the diesel will enter the oil tank. ( Overhaul the fuel injection pump to eliminate leakage).

Diesel is generally entered into the engine from high-pressure oil pumps and oil pumps (hand oil pumps). It is more likely to enter from the oil pump.

There are three possible reasons: the fuel injector is broken, the amount of fuel injection is large, and the cylinder can't burn out and run into the body.

According to the analysis of the situation: the oil nozzle is stuck, the valve rod is dead, the oil pump is excessively worn, and the high-pressure fuel injection pump plunger seal is rotten. It is recommended to go to the repair shop or 4S store for inspection.

Hello, the high-pressure pump plunger is broken and the diesel is leaking into the oil. Let's check the high-pressure pump.

There are several reasons: the diesel engine idles for a long time, resulting in poor fuel atomization. Incomplete combustion; the pressure of the fuel injection head is insufficient. Caused by poor atomization of the oil nozzle; excessive oil in the injection head; and other reasons. The main thing is to distinguish the category of oil pump: PT pump. In-line oil pump. Common rail oil pump; the basic situation is roughly the same.

Who knows the parameters of Hyundai 450 excavator engine (M11)

1, L engine.Through the inquiry of Autohome, I learned that the 2018 Hyundai 150 excavator uses a 6L engine. Hyundai is a car brand under Hyundai Motor, one of the world's top 500 car companies. Its main models include Sonata, Elantra, Santa and Tucson. Hyundai ranked sixth in the world in brand sales in 2019.

2. The Hyundai R385LC-9T excavator is standardly equipped with a 5m heavy-duty arm, an 8m heavy-duty arm, and a QSM11-C six-cylinder turbocharged medium-cooled electric diesel engine provided by Cummins.

3. Generally, 450 represents about 45 tons of weight, which is named after weight. It depends on the specific configuration.

4. Operating weight Operating weight is one of the three important parameters (engine power, bucket capacity, operating weight) of the excavator. The operating weight determines the level of the excavator and the upper limit of the excavator's excavation force.
