What's wrong with Cummins m11 burning blue smoke

1. The Food additives HS code classificationcombustible 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.

2. The characteristics of the M11 model are high power and small size, which means that its material must be excellent, so the maintenance should be more careful than other engines.

Introduction to Sterling Engine

1. Sterling engine is an 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 is the reason for the black smoke of the Chongkang M11 engine at idle?

1. The black smoke from the engine is the result of the injected fuel not being fully burned.The possible reasons are excessive oil supply, low oil supply pressure of the fuel injector and poor atomization, too small oil supply angle and late oil supply time, etc.

2. Another reason is that the cylinder pad of the water-cooled engine is broken, and cold water enters the cylinder. If the water in the water tank is consumed too quickly in the absence of leakage, and the exhaust pipe is slightly white, the cylinder pad should be replaced for this reason.

3. The oil supply is too large. Excessive oil supply increases the amount of oil entering the cylinder, resulting in incomplete combustion of fuel with more oil and less gas. In addition, excessive workload, poor fuel quality and low working temperature will also cause black smoke from the exhaust.

4. Ignition problem: spark plug electrode gap is too small or too large, ignition coil problem, etc. Solution For the fuel problem, it can be solved throughReplace the oil line system, repair or replace the fuel pump and fuel injector, clean the oil line system, or replace heavy fuel.

5. The reasons for the engine's black smoke are as follows: 1. Automobile overload or engine overload; insufficient cylinder pressure, low engine temperature; improper adjustment of the carburetor; blocked empty air filter; individual cylinders do not work, ignition is too late; the intake and exhaust valve is not tightly closed, the combustion gas is poor, the combustion deteriorates, and the flue gas rises.

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

L engine. Through the inquiry of Autohome, I learned that the 2018 Hyundai 150 excavator uses a 6L engine. Modern is the world.The car brands under Hyundai Motor, one of the top 500 car companies in the industry, include Sonata, Elantra, Shengda and Tucson, etc. Hyundai ranked sixth in the world in brand sales in 2019.

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

Generally, 450 represents about 45 tons of self-weight, which is named by weight. It depends on the specific configuration.

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.

The bucket capacity is 2 cubic meters, the engine power is 257kw, and the maximum excavation width is 1200mm.

How many horsepower is the Hitachi 210 excavator engine (1 Hitachi ZX210H-3G excavator parater: engine rated power (ISO9249, net): 122kW (166PS) that is, the net rated power is 166 horsepower.

What does Cummins m11 engine fault code 111 mean?

1. First, start the Cummins engine reling tool. Secondly, use the turn-up tool to turn the engine to the stop position on one cylinder. Finally, fix it, and you can use the Cummins engine roaring tool.

2. Memory error. Cummins ISM series engine fault code query table, fault generationCode 251+9 is a memory error, 115 is a power line failure, and 218 is an oil-water separator failure.

3. Background knowledge: If the electronic control unit (ECU) detects a fire that may cause damage to the catalytic converter, the fault indicator light will flash, and the engine should be turned off immediately. The fault code indicates that there are multiple cylinders on fire or the electronic control unit (ECU) cannot determine which cylinder is on fire.

4. It is the fault code of the leakage of the heating tube. It needs to detect the heating tube of the electric water heater and replace the heating tube.

5. If the engine fault indicator light on the car dashboard is on, you can continue to drive. The color of the engine fault indicator light is yellow, which reminds the driver that the engine may be faulty and needs to be overhauled.

6. Hello, if your engine is a Cummins engine, this fault code should be the ECU power supply output voltage 2-voltage higher than the normal value or the high-voltage power supply is short-circuit fault, and the fault light is yellow. It is recommended to go to the service station as soon as possible to troubleshoot the line so as not to affect your car.

Cummins m11 engine disassembly steps

Place the engine vertically. Remove the fixing screw of the cylinder head. Note that the screws should be loosened from both ends to the middle, and the screws should be removed three times. Lift the cylinder head, remove the cylinder cushion, and pay attention to the installation direction of the cylinder cushion. Loosen the oil release screw of the oil span shell and drain the oil in the oil span shell.

Put the engine sideways and check whether there are marks on the clutch cover and flywheel. If there is no mark, it should be made up.Then turn the crankshaft flywheel, remove the eight clutch fixing bolts symmetrically and evenly around the clutch cover, and remove the clutch assembly.

Remove the fixing screw of the cylinder head, note that the screw should be cross-spinned from both ends to the middle, and remove the screw in 3 times. 2) Lift the cylinder head. Remove the cylinder pad and pay attention to the installation direction of the cylinder pad. Loosen the oil release screw of the oil span shell to release the oil in the oil span shell.

The general operation process of removing the cylinder head from the cylinder block is as follows: removing the electrical connector, accessories and water pipe → removing the intake manifold → removing the exhaust manifold → removing the timing belt → removing the valve chamber cover → removing the cylinder head. The details are as follows: Process 1: Remove the electrical connector, accessories and water pipe 1 Remove the fuel pump fuse.

1 Use the main support frame to support the car on the flat ground.2 Turn the main switch to the "OFF" position. 3 Remove the outer cover of the car. 4 Dray the engine oil. 5 Remove the negative wire of the battery first, and then remove the positive wire. 6 Remove the carburetor and automatically start the thickening valve wire.

Disassemble the Cummins engine air pump water pipe with supporting tools according to the steps. Remove the outer cover of the water tank. Remove the fan belt. Depending on the situation, it is more convenient to remove and install the water pump from the water tank. Remove the three fixing screws of the water pump, and remove the water pump with a little force with your hand.
