Where is the Crankshaft Positioning Hole on the Roewe 550?

The crankshaft positioning hole on the Roewe 550 is located next to the crankshaft position sensor and the crankshaft pulley. The crankshaft is the most critical component in the engine, bearing the force transmitted by the connecting rod and converting it into torque, which is then output through the crankshaft to drive the engine's accessories. Below is relevant information: 1. Crankshaft: The crankshaft is subjected to the combined effects of centrifugal force from rotating masses, periodically varying gas inertia forces, and reciprocating inertia forces, causing it to endure bending and torsional loads. Therefore, the crankshaft must have sufficient strength and stiffness, with wear-resistant journal surfaces, uniform operation, and good balance. 2. Crankshaft Journals: To reduce the mass of the crankshaft and the centrifugal force generated during operation, crankshaft journals are often hollow. Oil holes are drilled on each journal surface to allow oil to flow in or out for lubricating the journal surfaces. To minimize stress concentration, transition arcs are used at the connections between the main journals, crankpins, and crank arms. The crankshaft counterweights (also known as balance weights) function to balance the rotating centrifugal forces and their moments, and sometimes also to balance reciprocating inertia forces and their moments.

What are the differences between the Cadillac CT4 and CT5?

CT5 adopts a front-engine, rear-wheel-drive layout and features standard C-segment dimensions (4924*1883*1453mm, wheelbase 2947mm), making it slightly larger than the CT4. The CT4 is positioned as a lower-tier model. Although it shares the same 2.0T engine as the CT5, its transmission is 'downgraded' from a 10AT to an 8AT, coupled with a length of 4756mm and a wheelbase of 2775mm (CT4-V). Below are detailed comparisons between the two: 1. CT5 is larger: The CT5 can be considered a competitor to the 34C (referring to BMW 3 Series, Audi A4, and Mercedes-Benz C-Class), with pricing similar to the main models of the 34C and a noticeably larger size, aligning well with Cadillac's competitive strategy. 2. CT5 is positioned higher: Additionally, to boost sales volume, Cadillac has consistently emphasized in its marketing that the CT5's direct competitors are the 34C, reinforcing this perception. In reality, from a cost-performance perspective, the previous ATS-L could only compete with the 13A (entry-level models of the 34C), and the CT4 is likely to follow a similar path in the future.

Is the Environmental Protection Label Required to be Displayed?

No, according to the new regulations jointly issued by the Ministry of Environmental Protection and the Ministry of Transport, the green environmental protection label was abolished in 2018. Although the green environmental protection label for motor vehicles has been canceled, vehicles still need to undergo exhaust emission testing, which remains the same as before. New vehicles eligible for the 6-year exemption from inspection do not require exhaust emission testing. Now, you only need to obtain the annual inspection label and display the compulsory insurance label, meaning it is combined with the annual inspection label. Below is additional information: 1. Regulation: This regulation was jointly issued by the environmental protection and public security departments, meaning that vehicle owners no longer need to obtain or display the environmental protection label. However, the relevant exhaust emission testing must still be conducted, as passing this test is still necessary for the annual inspection to be approved. In other words, the environmental protection label has been merged with the annual inspection label, and the most noticeable change for vehicle owners is that they now need to display one less label. 2. Revised Annual Inspection Regulations: In addition to canceling the environmental protection label, the transport department has also revised the annual inspection regulations, such as allowing vehicle owners to conduct annual inspections online, conduct inspections in different locations, and eliminating certain fees. The reduced fees mainly include the appearance inspection fee and document printing fees. Vehicles eligible for the 6-year exemption from inspection can conduct the annual inspection online, and the relevant certificates will be delivered by mail with payment upon receipt.

What is the fuel tank capacity of the Geely Emgrand GS?

The fuel tank capacity of the Geely Emgrand GS is 60 liters. Below are some related details about the fuel tank of the Geely Emgrand GS: 1. Tank Material; The fuel tank of the Geely Emgrand GS is made of high-strength engineering plastic. 2. Fuel Tank Usage Precautions: Do not wait until the fuel warning light comes on to refuel. Before driving, check the fuel gauge and calculate whether you need to refuel during your trip based on the distance and the fuel gauge reading. The fuel pump is located inside the tank and operates at a high temperature when continuously working. Being submerged in fuel helps to effectively cool it down. When the fuel warning light comes on, it indicates that the fuel level is below the fuel pump. If you always wait for the light to come on before refueling, it will shorten the lifespan of the fuel pump. Having too little fuel in the tank may also cause the fuel pump to burn out; Choose to refuel in the morning or evening. Gasoline has the property of thermal expansion and contraction, and it is charged by volume. At lower temperatures, gasoline has a relatively higher density, meaning the mass per unit volume increases, allowing you to get more fuel for the same price; Avoid filling the tank completely when driving in the city. When driving in urban areas with frequent stops and starts, there is no need to fill the tank completely. A full tank adds extra weight to the engine, increasing fuel consumption, so it is unnecessary to fill it up.

Is It Necessary to Install a Bug Screen on a Car?

If you don't frequently drive on highways, it's not recommended to install a car bug screen. A car bug screen is a very fine protective mesh, and its installation will inevitably affect the radiator's airflow cooling, leading to reduced radiator cooling efficiency and potentially causing the radiator to overheat or even boil. Here is more related information: 1. The function of a car bug screen: A car bug screen is installed on the outer part of the radiator at the front of the car, on the radiator frame. Its main purpose is to block leaves, insects, gravel, and other debris from hitting the radiator through the front grille, protecting the radiator from damage and keeping it clean. Many people refer to it as a radiator protective screen. 2. The drawbacks of a car bug screen: Car bug screens are usually fine meshes installed in front of the radiator, which can indeed block a lot of debris. However, precisely because of their fine mesh, they can obstruct the radiator while driving. Normally, the radiator can be cooled by the high-speed airflow generated during driving, but with this protective screen, the airflow is weakened. In other words, the radiator's cooling efficiency is directly reduced. For urban roads where driving speeds are already slow, and especially for older cars, this can easily lead to the radiator overheating or even boiling. 3. Maintenance of a car bug screen: If a car bug screen is installed, the owner should regularly remove the screen for cleaning to prevent excessive debris buildup, which could affect the radiator's cooling. If no bug screen is installed, the owner should also regularly clean the engine compartment, especially the condenser and radiator.
