My car doesn't have a turbocharged device. Can I install it by myself?

1. No, unless you have professional skills. Turbocharging is not enough to install a turbine on the engine, but also needs to adjust the whole engine, such as fuel injection, ignition time, valve switch, etc. If it is just a simple addition of a turbine, it may cause the engine to "knock the cylinder" or even damage! Find a professional to install the turbine.

2. First of all, I can tell you clearly that naturally aspirated engines can be equipped with turbines, and each engine can be equipped with turbines, which is not as complicated as you think! Let me tell you with practical actions, and today I will share a few cases with you.

3. Technically, turbocharging can be added, but it is better not to install it.It is illegal to modify the engine. The vehicle cannot pass the annual inspection, and the cylinder strength of the turbocharged engine is not comparable to that of the self-aspirated engine. How big the air intake pressure of the turbine is a technical job.

4. Yes, a turbocharged engine is an engine that relies on a turbocharger to increase the engine intake. A turbocharger is actually an air compressor.

Steps for disassembly and installation of the car engine?

1. Remove the fixing screw of the cylinder head. Note that the screw should be crossed and loosened from both ends to the middle, and the screw should be removed three 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.

2. Place the engine upright and remove the intake and exhaust manifolds and cylinder head outlet pipes. Remove the cylinder head cover, remove the rocker arm shaft assembly on the front and rear cylinder head; remove the crankshaft ventilation pipe, and remove the boom chamber cover; remove the putter.

3. The disassembly and installation method of the engine includes the following steps: remove the fixing screw of the cylinder head, loosen it from both ends to the middle, and remove it three times;Lift the cylinder head, remove the cylinder pad, release the oil release screw of the engine oil sup, and release the engine oil sup.

4. The engine disassembly steps are carried out in the order of machine, assembly, parts, assembly and parts. Pay attention to proofreading the assembly mark when disassembling to ensure that it can be reassembled as it is. When disassembling various threaded connectors, it should be disassembled in a professional symmetrical order to ensure the complete disassembly of the threaded connectors.

5. Remove the front mask and baffle of the engine. First, loosen the six nuts fixing the front mask cover and the two fixing bolts on the left and right of the radiator, and remove the front bumper, as shown in Figure 3. Loosen the four hexagonal fixing nuts in front of the front mask and remove the front mask. Loosen the two screws fixing the condenser on the longitudinal beam.

6. Remove it in the gearbox bodyDismount assembly: First remove the clutch cover and the flywheel connection bolt, and then move the detacher up and down from the flywheel. III) Disassembly and installation of the engine 1) Remove the 13 fixing screw of the cylinder head, note that the screw should be rotated from both ends to the middle, and remove the screw in 3 times. 2) Lift the cylinder head.

How long does it take to preheat the car? How long?

Under normal circumstances, it only takes about one minute to heat the car in place. When the speed reaches about 800 rm, or the water temperature reaches the normal value, you can drive according to your driving habits. Before that, don't step on the accelerator or drive violently. Do not turn on the indoor hot air. Turning on the indoor hot air will prolong the engine heating time.

Under normal circumstances, idle for about one minute to warm up the car in place.When the speed reaches about 800rpm or the water temperature reaches the normal value, you can drive according to your own driving habits. Before that, don't step on the accelerator or drive hard. Do not turn on the indoor hot air, because turning on the indoor hot air will extend the heating time of the engine.

Winter is coming, and the car needs to start for 30 seconds to 1 minute.

In winter, the cold car starts to warm up for 35 minutes. After a long time of parking, the oil in the engine flows back to the bottom oil shell of the engine. Therefore, after ignition, the upper half of the engine is in a state of lack of oil and lubrication. About 30 seconds after starting, the oil will be pumped The operation and the oil is delivered to.

How long does it take to start the vehicle in winter? In the process of driving the vehicleIn the middle, the car mainly masters certain driving skills. Only in this way can the wear of parts be reduced and the service life of the vehicle be extended. So how long does it take to start the car in winter? It takes about 1 to 2 minutes to start the vehicle in winter, and it can be driven when the engine speed is stable.

Generally, after we start the car, we will find that the speed of the car is about 1200 rpm. After the car starts for about a minute, the speed of the car will drop to about 800 rpm, and then the hot car is completed.

What is the disassembly process of the timing chain of the car engine?

Remove the engine front cover from the disassembly of the timing chain and sprocket of the GL8 (Luzun) car.

launchThe replacement steps of the small chain of the machine are: disassemble the valve chamber cover, remove the crankshaft pulley, and remove the timing chain shell; rotate the crankshaft, turn the crankshaft to the upper stop point of a cylinder, and unswew the crankshaft to fix the crankshaft.

Remove the plug installed in the timing pin hole on the engine body and rotate the flywheel to align the flywheel pin hole with the engine cylinder block pin hole. Insert the timing pin hole and flywheel pin hole of the engine cylinder block with the timing pin locking special tool TEN00002, lock the flywheel, and use the camshaft locking special tool TEN00004 to lock the camshaft phase.

The replacement steps of the timing chain of the automobile engine are as follows: remove the valve chamber cover, crankshaft pulley and timing chain cover; turn the crankshaft to the upper stop point of 1 cylinder, tighten the crankshaft fixing screw, and fix the crankshaft;Rotate the intake and exhaust camshafts, and there are grooves at the rear end of the camshaft. Align the grooves of the two camshafts in a balanced way and clamp the special tools.

If necessary, remove the oil, remove the oil pump, remove the oil pan of the timing chain tensioner, and take off the main gear and camshaft gear in turn. The Wuling Zhiguang 465 engine is a timing belt, the Wuling Zhiguang B series engine is a timing chain, and the Wuling Hongguang is a timing chain.

What is the appropriate speed when the car is idling?

When the engine is idling, the speed can generally reach 700~1100.

The normal speed of engine idling when the car is hot is 550-800 rpm; the normal speed of engine idling when the car is cold is 950-1300 rpm.

Normally, it is generally 700-800 rpm. If the engine is too low, it is easy to shake, and if it is too high, the fuel consumption will be high. As long as it does not shake, design engineers hope to try to be as low as possible to save fuel.

When the car is hot, the engine idle speed is generally 550-800 rpm; when the car is cold, the engine idle speed is generally 950-1300 rpm.

First of all, different models have different idling values because of different engines. Generally, the normal idling speed of the car will not exceed 1000 rvel, and it is basically about 600-900 rvel. But in cold start, the idling speed will be relatively high.

The engine has good working performance, and the normal idle speed is generally 550-800 rpm. The idle speed can be adjusted by adjusting the size of the throttle opening, the amount of idling fuel supply, etc.Generally speaking, the idle speed is the minimum speed when the engine does not shake within the idle speed range and the acceleration performance is good.

What kind of car is the Little Angel logo?

Rolls-Royce. The logo of Rolls-Royce is the logo of the Flying Goddess. Rolls-Royce was founded in the United Kingdom in 1906 by Frederick Henry Royce and Charles Stewart Rolls.

The winged villain is the logo of Rolls-Royce, commonly known as the Silver Angel. Its letter logo is the letter R with two centimeters on the left and right, commonly known as double R. In fact, the little man with wings is the goddess of joy, and the process of her creation and creation is an excellent example of Rolls-Royce's pursuit of perfection.
