The timing of Citroen C5? It better be urgent.

1. Align the crankshaft according to the marks on the crankshaft timing pulley. Generally, the piston top dead center position of a cylinder is needed;

2. Install a mark on the camshaft timing pulley, aim at the camshaft, and aim at the positions of the two camshafts respectively for double camshafts;

Third, install the timing belt/chain.

Only the camshaft gear is marked on the engine timing gear, and other gears are not marked. First, rotate the engine to make the first and second cylinders reach the top dead center. Then assemble other gears except camshaft gear, and see that there is a mark on the machine body, so that the mark of camshaft gear coincides with this mark. After that, rotate the engine to make it about 22 degrees before the top dead center, adjust the fuel injection pump to make it in the state that the first cylinder has just delivered oil, and tighten the screws.

Introduction to Citroen C5:

1. Appearance: The appearance size of Citroen c5 ranks in the top of m2 (mid-to-high-end models) and is close to H (high-end models). Its length and width (4.82m and1.82m, respectively) are higher than those of Citroen Sandia xantia and close to the size of Citroen xm. And the height of 1.48m (Sandia and xm are 1.40m and 1.39m respectively) makes it really stand out from the crowd. From the hood to the rear of the engine, from the A-pillar to the C-pillar, an arc runs through it. Coupled with the slightly picked waistline, it looks very smooth from the side. Although c5 pays great attention to the smoothness of contour lines, the interior space is not greatly affected by the curvature of the roof, and it is relatively spacious in the same level. The front seat can be adjusted in four directions: up, down, front, back and forth, and the inclination angle of the chair back and the height of the cushion can also be adjusted. With the four-way steering wheel, people with average figure can easily find the right driving position. The back seat space is also ideal, which can meet its business purposes.

2. Interior: The interior design of Citroen c5 is slightly commercialized, which can be clearly felt from the mahogany decoration on the center console and the door and the traditional air conditioning outlet. Of course, apart from these factors, c5' s interior design is still fashionable, such as the depth of interior color, leather electric adjustable front seats, door handles with unique shapes and uses, fan-shaped air conditioning control buttons on the center console and so on. In particular, its silver metal with black leather shift lever highlights the technological atmosphere of the vehicle. In addition to the dashboard, there is also an information display screen on the upper part of the c5 center console, which makes the information such as sound, vehicle suspension height, time, outside temperature and driving state clear at a glance, which is practical.

3. Engine: c5 has two types of engines to choose from, namely 2.0l and v63.0l engines, both of which adopt multi-valve design (16 and 24 valves respectively). The maximum power 100kw(6000r/min) and the maximum torque of 2.0l engine reach190n m (4100r/min), which is similar to the dynamic performance of Audi a4 1.8t in data and the actual test experience is basically the same. From the actual performance, the power of 2.0l machine is slightly less than that of 3.0l machine, but it should be enough if it is not particularly critical of power. Both models are equipped with a 4-speed automatic gearbox, with intelligent design and "sequential shift control" function, which combines the advantages of manual and automatic gearboxes, and the driver can switch at any time as needed.

4. Highlights: The third generation active hydraulic suspension technology adopted on c5 is the biggest highlight of c5 car. It combines the latest electronic technology with the newly designed hydraulic structure. By adjusting the ground clearance of the car body, the driving stability of the vehicle is ensured and its passing capacity is improved. When the vehicle speed drops below 10km/h, the height of the vehicle body automatically rises to the highest position, which can reach 27cm, and ordinary obstacles can be easily crossed; When the vehicle speed exceeds 1 10 km/h, the car body can be reduced to the minimum ground distance of 7cm, which can effectively reduce the wind resistance, drive more smoothly, grip the tires more firmly, and save fuel. When the car stops and stops, the height of the car body will be automatically reduced to the lowest, and then it will return to the normal height after starting the car. At the same time, c5 also adopts advanced multiplexing technology, including four relatively independent networks of 20 modules and an intelligent control module, which are connected by a public bus. The system can realize a variety of automatic control functions, including automatic lighting control, automatic wiper, electronic parking assistance, automatic tire pressure detection and so on.
