How to disassemble the Chery 477 engine oil span

1. After removing all the fixing screws, knock slowly at the junction of the oil span and the cylinder block with a flat chisel, and sand it with a flat screwdriver and slowly smash it in.

2. Find an oil iron basin or an empty barrel to prepare. Find the tool to deal with this oil pan big rose in the toolbox, such as opening, movable plate hand, plum blossom, sleeve to remove the oil pan rose, unswew out the big rose, and let the oil flow into the plate, into the barrel or, until the flow is finished.

3. In order to avoid bending of the oil span, the bolts of the oil pan should be unstwewed diagonally from both sides to the middle, and then put the oil span on the bracket. Any bending of the oil san or damage to the installation surface will cause oil leakage. Therefore, before installing the oil span, be sure to remove the old sealing gaskets and gaskets.

Is the 477-engine of Chery Fengyun 2 a high-speed engine?

1. Fengyun 2 uses the CAC-SQR477F engine, with a maximum power of 80KW/6000rpm and a maximum torque of 140Nm/3000rpm. The lift power of the engine reaches 544Kw/l. In terms of chassis, the Fengyun 2 is not much different from the Fengyun series models. It adopts the front McPherson rear longitudinal arm torsional beam suspension.

2. Fengyun-2 adopts CAC-SQR477F engine, with a maximum power of 80kw/6000rpm, a maximum torque of 140N·m/3000rpm, and an engine power of up to 544kW/L. Chery Fengyun 2 is a new fashion life model (including sedans and hatchbacks) developed on the current Chery Yunqi chassis platform. The appearance of the new car is very different from that of the old Chery.

3. Models equipped with sqr477F engine (i.e. ACTECO 5) include Fengyun 2, Qiyun 3 (formerly A516), Qiyun 2 (formerly Qiyun 5) Unlike other engines, this engine adopts single overhead camshaft technology.

What is the right position of the crankshaft and flywheel of the Chery 477 engine?

Aft the crankshaft according to the mark on the crankshaft timing pulley, the stop position of the piston of 1 cylinder is generally required; the marking on the camshaft timing pulley is aligned with the camshaft, and the double camshaft is aligned with the two camshaft positions respectively; the timing belt/chain is installed.

. The installation of the camshaft timing gear Check the upper stop position on the gear, which should be aligned with the timing mark on the first bearing cover of the cylinder head. Note: The timing mark on the first bearing cover of the cylinder head is not directly above. Install the gear pads and bolts. After tightening the bolts by hand, tighten them with a kilogram force wrench. The camshaft must be locked when tightening.

Install the flywheel on the rear end of the crankshaft, position it with two positioning bolts during installation, and then tighten the nut.The fastening torque is 137-147N·m. Install and fix the main bearing on the main bearing seat of the crankshaft, and apply a thin layer of oil on the surface.

The positioning method between the flywheel and the crankshaft is the positioning pin and the asymmetrical bolt. The flywheel and the crankshaft are carried out through the dynamic balance experiment together during manufacture. In order not to destroy the balance between them during disassembly and installation, there should be a strictly unchanged relative position between the flywheel and the crankshaft.

Find the position of the stop point on the first cylinder compression stroke, and loosen the spark plug of the first cylinder. Slowly shake the crankshaft. When you hear the degassing sound, it means that the first cylinder is compressing the stroke. Open the inspection hole cover on the flywheel shell, and then slowly shake the crankshaft to align the timing mark.

Chery gave up the 477 engine

The fuel consumption of the Chery 477 engine is relatively high, which cannot fully meet the needs of consumers for economy and energy saving. When driving at high speed, the engine noise is relatively loud and not stable enough. In the process of use, due to production process limitations, some engines have problems such as high fuel consumption and jitter.

Chery has been discontinued. Now all 6 477 engines are 5 displacements. The dynamic 481 engine is much better than 477, and the fuel consumption is not much higher than 477. It is recommended to choose 481 if it is helpful to you. Please adopt it.

Chery has never used imported engines, but foreign outdated technology is produced domestically. Do you want to ask if the engine is made by BMW? I want to tell you that it's not. It's just that a mini cooper has used this engine. Only a small batch has been used, and it will not be used later.

The Chery 477 engine is still relatively durable. The foundation of the Chery 477 engine is relatively mature, and the workmanship quality is also very good, and the materials are also very generous. The Chery 477 engine is not prone to problems during use, and can be used for ten years or 1 million public. Inside, and there is no need for any maintenance after many years of use.

ACTECO-SQR477F is 5 displacements, and the power is weak. ACTECO-SQR481FC is 8 displacements, and the power is not bad. The fuel consumption between the two is not much different, and the maintenance cost is about the same. It is recommended to buy 8 displacements.

Chery 477 engine disadvantages

Chery Qiyun 3 engine idling shakeCause of movement 1 The most common cause of unstable idling and jitter of the car engine is the lack of cylinder. Lack of cylinder refers to the four working cylinders or six working cylinders of an engine. Some cylinders do not work or do not work well, which will lead to unstable engine power output, resulting in engine shaking and engine lack of cylinders.

F is characterized by strong low-speed torque, fast start, and good fuel economy, which is very suitable for driving habits in cities.

However, the disadvantage of this engine is that its power is moderate at high speed, and it is noisy at high speed, so it is not suitable for long-distance running.

Park the car in a place with a drain. After cleaning, sewage will flow to the ground in the engine compartment of the car, which is not good for polluting the environment, so it is recommended that you park the car in a place with a drain before cleaning the engine.
