Through the variable speed gearThe structure is controlled by the control mechanism and realizes the function of speed change through the clutch. The automatic transmission is generally a hydraulic torque converter automatic transmission, which is mainly composed of two parts.
Cummins engine installation belt, first hang the bottom of the engine belt on the crankshaft gear; the specific operation steps are as follows: first hang the bottom of the engine belt on the crankshaft gear. Bypass the oil pump gear and hang it on the balance shaft gear. Bypass the guide wheel. Hang it on the camshaft gear.
This Dongfeng Tianlong flagship KX has three chassis parts from Dongfeng Cummins, Eaton and Dongfeng Dener respectively. In terms of chassis, the real-life car is front and rear plate springs, and the setting of front 2 and rear 3 is relatively conventional. The front axle is maintenance-free axle, and the rear axle is a single-stage axle with double 440, and the speed ratio is 64.
Engine assembly + gearbox assembly The engine assembly is composed of two major mechanisms and five major systems.The two major mechanisms refer to: including the crank connecting rod mechanism and the gas distribution mechanism. The five major systems are: start-up system, lubrication system, fuel supply system, cooling system and ignition system! The diesel engine is composed of two major mechanisms and five major systems in addition to the ignition system.
The position of the Dongfeng Cummins crankshaft sensor needs to follow the following steps: find the engine compartment wrench at the bottom left of the main cab, and press the wrench to open the engine compartment lock. Press the wrench in front of the engine compartment cover to open the engine compartment cover. Use the hydraulic rod to support the engine compartment, so that the layout of the engine compartment can be seen.
Remove the plastic cover and the motor assembly. Disassemble the powertrain, and you will find a water pipe below. Disassemble it. Because the water is in the pipe, the antifreeze will gush out after removing the pipe. Please heat it carefully.
Check whether there are cracks in the lower part of the convex edge on the cylinder liner of the diesel generator, the lower part of the cylinder liner of the diesel generator and the sealing ring groove of the cylinder liner of the diesel generator. Magnetic flaw detection or color flaw detection can be used for inspection. If there is any form of crack in the cylinder liner of the diesel generator, it must be replaced.
The assembly must pay attention to cleanliness. If the assembly body is mixed with mechanical impurities, dust and sludge, it will not only accelerate the wear of parts, but also easily cause oil line blockage and accidents such as burning tiles and holding shafts. For example, when replacing the new fuel injector, the anti-rust oil must be removed from the clean diesel at 80℃, and the sliding test must be done before assembly and use.
Diesel generator unit replacement and repair, pay attention to some fitting parts should be replaced in pairs.
How to change the oil of the Cummins diesel generator: place the generator set in a plane and start the engine for a few minutes to raise its oil temperature and stop the engine. Remove the oil-refueling bolt (i.e. the oil ruler).
Pay attention to the replacement of accessories. First of all, refer to the maintenance manual for replacing accessories. Secondly, how big the screws are used, whether the screws assembled in place are tight, and then the order and cleanliness of assembly. Attention should be paid to the repair of replacement parts: whether the trademark is complete, whether the quality of the genuine outer packaging is good, whether the handwriting on the packaging box is clear, and whether the overprint color is bright.
Compare the new oil and the used oil drop by drop on the white filter paper. If there are more black spots in the used oil droplets, it indicates that the oil has not deteriorated and should not be replaced; if the oil is dark brown, it is deteriorated and should be replaced.
1. Diesel engine replacement repair and assembly must pay attention to cleanliness. If the assembly body is mixed with mechanical impurities, dust and sludge, it will not only accelerate the wear of parts, but also easily cause oil line blockage and accidents such as burning tiles and holding shafts. Therefore, we should pay attention to ensuring the cleanliness of the parts when replacing, repairing and assembling diesel engines.
2. Alloy steel. The Cummins valve bar is a Cummins engine accessory. The main material is alloy steel, which is mainly used to support the valve, as well as lubricating the valve and valve conduit to prevent the wear of the valve and the valve duct, and prevent the valve gap from being too large and causing the valve knocking sound.
3. According to the official website of Cummins Aonan, it is a new generation of ultra-quiet, highly reliable, environmentally friendly, digital generator set.It is the world's leading small marine generator set with automatic fault diagnosis display function.
4. Piston. Cummins K19 Piston 3631246 Shougang Heavy Vehicle Mining Vehicle Engine Accessories, Engineering Machinery Accessories. Cummins has a wide range of diesel and natural gas engine products, with a displacement covering 2. 8~95 liters, power 46~4200 horsepower super power covering 500~815 horsepower, maximum torque 3086 Newtons. Rice.
5. The main components of Cummins generator I: Air intake system: The air intake system of Cummins engine is composed of intake pipe assembly, air filter assembly, supercharger, intercooler, intake manifold and intake valve.
6. Engine accessories: cylinder head, cylinder block, supercharger, oil span, etc.Air intake system: air filter, throttle valve, air intake resonator, intake manifold, etc. Crank connecting rod mechanism: piston, connecting rod, crankshaft, connecting rod tile, crankshaft tile, piston ring, etc.
STC controller, graded timing.When the engine speed is low, the engine timing is advanced, which makes the engine combustion and emission better. When the engine is heavily loaded at high speed, the STC valve does not work and returns to normal timing.
According to the query, the size of the Cummins k19 fan bracket bearing is 22 cm inner diameter, 50 cm in outer diameter, 10 cm in thickness and 15 g in weight.
Cummins cylinder head, different types of bolts, have different kilograms to withstand. For example, the No. 8 screw is about 25 kg, and the No. 9 bolt is about 42-45 kg. Bolt: mechanical parts, cylindrical fasteners with threaded nuts.
Made in Chongqing. The k19 engine number 3088301 is an engine produced by Chongqing Cummins. Cummins engine is made by Cummins.Designed and manufactured by the company, the Cummins engine has a displacement of 4~91 liters, and the power range covers 31~3500 horsepower.
In addition, at a low speed of more than 2,000, the car body has obvious shaking, and the acceleration is weak. The higher the speed, the shaking is reduced. This phenomenon is mostly related to the inability of the ignition coil. Open the engine cover and observe the running engine, and find that the engine has obvious jitter, which does not belong to the shaking in the normal working state of the engine, and the shaking amplitude is very large.
1. OK. According to the official website of Cummins Aonan, it is a new generation of ultra-silent, highly reliable, environmentally friendly, digital generator set. It is the world's leading small marine generator set with automatic fault diagnosis display function.
