How about the Foton Cummins x12 engine installed in the Dayun heavy truck in December 2019?

1. It's okay. As soon as the debut of the Foton Cummins X12, it was highly expected to change the efficient logistics industry. This competition is like a coronation ceremony announcing the strong arrival of the Foton Cummins X12! This is the first official debut of the Cummins classic power platform X series engine in the Chinese truck market.

2. Kilometers. While the Foton Cummins x12 engine has high horsepower, the Cummins X12 also has ultra-high fuel efficiency, intelligentIt can upgrade technology, such as the organic integration of ADEPT's cutting-edge electronic control function and AMT, and the significant upgrade of the fuel system, which greatly improves its fuel-saving effect. According to the relevant data of the X12 engine, its life span is more than 1,000,000 kilometers.

3. Oman CX12 represents the engine model, Foton Cummins X12 engine, the real displacement is 18L, and the chrome blue 510 represents the maximum power of this engine is 510 horsepower. The Auman brand also expresses the brand characteristics of "quality, technology, intelligence and comfort" from the connotation of the name.

What is the structure and working principle of the X-type engine?

1. Type X is two V-type opposites connected to a crankshaft.This picture is a 4-cylinder two-stroke motorcycle engine, which should be the simplest X-type engine.

2. Most star engines are air-cooled engines, which need to be cooled by the airflow of the windward surface. If it is installed on the car, in order to get the best cooling effect, it needs to be arranged along the center of the car, which is unsightly and even blocks the driver's sight.

3. Motorcycle engine x0dx0ax0dx0a motorcycle engine works in the same way as the car engine. The engine is composed of a piston, a cylinder block and a cylinder head, and the cylinder head contains a valve mechanism. When the spark ignites the mixture of fuel and air, it will cause an explosion, pushing the piston to move up and down in the cylinder.

4. The working principle of the engine is air intake-compression-oil injection-combustion-expansion work-exhaust.The following is the working process of the engine: in the intake stroke, the working quality entering the cylinder is pure air. Due to the low resistance of the intake system of the diesel engine, the air intake terminal pressure PA=(0.85~0.95)P0 is higher than that of the gasoline engine.

5. Working principle of the engine: The engine is generally four-stroke, and its working principle includes intake stroke, compression stroke, working stroke and exhaust stroke. Most car engines are four-stroke. Air intake: As the first stroke, this is mainly the process from the piston to the lower stop point on the cylinder.

6. The four-stroke gasoline engine completes a working cycle in the intake stroke, compression stroke, working stroke and exhaust stroke. ( 2) The intake stroke piston is driven by the crankshaft and moves from the upper stop point to the lower stop point. At this time, the intake valve is open, the exhaust valve is closed, and the crankshaft rotates 180°.

What is the difference between the performance of a long-stroke engine and a short-stroke engine?

Simply put: at medium and low speeds, the torque of long strokes is large. The maximum speed of the long-stroke is not as high as the short-stroke, so the short-stroke engine can reach a higher speed, and of course it can also reach a higher speed. Therefore, the maximum power of the short-stroke engine is large.

There can be no obvious difference. Relatively speaking, the medium and low speed performance of long strokes is slightly better, and the high speed performance of short strokes is slightly better, but the difference will not be too obvious, and it also depends on the engine model, speed ratio, actual quality and other aspects. Which one is not necessarily better in a certain aspect.

Short stroke: good high-speed performance and sensitive response. Because the crankshaft of the short-stroke engine rotates a circle, the piston runs up and down for a shorter running distance, and the running speed of the piston is lower, so the resistance generated by the inertia of the piston movement is lower, the engine is more likely to reach a high speed, and the speed response is more sensitive.

Therefore, compared with short-stroke engines, the speed of long-stroke engines is slow, and slow speed means that the power is relatively low. In this regard, the short-stroke engine has a greater advantage, because its rotation speed is relatively higher, the piston displacement is faster, and it can do more work per unit time.

How to solve the difficulty of starting the engine of Komatsu PC20MRx excavator?

1. In order to confirm that the engine is not faulty, remove the hydraulic pump and start the engine, and the engine can be started once. From this, it can be concluded that the failure is caused by excessive load on the hydraulic system at startup and has nothing to do with the engine.

2. The Komatsu excavator engine cannot start the solution: the density does not meet the regulations, indicating that the battery capacity is too low or there are other faults, and the battery should be charged or replaced.Once the fuse is melted, the start switch will be cut off, the starting motor will not work, and the engine will not be able to start.

3. In this case, you can disassemble the battery in advance, store it indoors, and install it in advance when it needs to start work.

4. Cause of failure There is too much carbon accumulation in the air intake system and the root of the intake valve, resulting in excessive concentration of mixed gas during cold start. Solution: Clean up the air intake system. The throttle valve is seriously dirty and the air intake is insufficient. Solution: Clean up the throttle valve. The speed of the starter does not meet the requirements. Solution: Increase the speed of the starter.

5. First of all, it should be ensured that the mechanical parts of the excavator can also work normally in cold weather. Regular inspection and maintenance of parts such as lubrication systems, fuel filters, batteries and wires can reduce mechanical failures when starting in cold weather.In addition, the use of fuel with low condensation point and appropriate oil can improve the cold start performance of the excavator.

6, so if the excavator fails, as long as the construction can continue, the owner will definitely choose to troubleshoot after the completion of the project, except for the engine problem! Engine failure problems are also a priority, such as difficulty in starting. In fact, you can solve it through self-examination and self-repair. Next, the editor will give you a detailed introduction.

Can the Jiangxi Isuzu mu-x engine be changed to twin-turbocharged

1. Single-turbocharged cannot be changed to twin-turbo, and twin-turbocharging uses two independent turbochargers The supercharging system of the device is usually equipped on an in-line 6-cylinder or V-type equivalent displacement engine.

2. According to your description. Can the 250-bell light truck be modified with a turbocharged engine? Under normal circumstances, it can be modified. As long as you can buy the matching accessories, there is no problem. Come to the professional store for modification. Only then can we ensure high quality. Hope to adopt.

3. Ordinary cars cannot be modified with turbocharged cars. The engine model and frame number cannot be changed, and the body structure cannot be damaged. If the car changes color and the engine, body or frame is replaced, the car must be checked. If the engine, body or frame is replaced, the motor vehicle safety device must be submitted.

4. The self-priming car engine can be changed to turbocharged. If the self-priming car engine is to be changed to a turbocharged car engine, it must be equipped with a turbocharger, and the compression ratio piston must be replaced at the same time.
