What issues should be paid attention to in Subject 2?

Precautions for Subject 2 test: 1. Mock test: The purpose of the mock test is to familiarize the candidate with the test environment, and at the same time, the coach can guide on the points where marks are easily deducted. Therefore, the mock test is absolutely essential, and full preparation is necessary to best face the challenge. 2. Relax: Dress comfortably before the test and be mentally prepared; pay attention to the key points when reversing into the garage, do not turn left or right; when parking in a side position, ensure the rear wheel exceeds the edge line of the garage, adjust the distance properly, remember to turn on the turn signal and honk the horn. When making a sharp turn, steer the wheel decisively after aiming at the correct position; when driving on a curve, make a wide turn after entering the curve, maintain a steady speed, and avoid crossing the line in all the above situations. 3. Pay attention to signing: After the test, drive the car back to the starting position, sign the confirmation, and then turn off the engine. 4. Bring your ID card: You must bring your ID card to the test, as you cannot take the test without it. After so much preparation, do not let the lack of an ID card prevent you from taking the test. Additionally, make sure to turn off your phone during the test, as any sound from the phone will be considered cheating.

How much does the LaCrosse weigh?

LaCrosse body weight: 1770 kg. Below is relevant information about the LaCrosse: 1. Body dimensions: Length 5031mm, width 1853mm, height 1458mm, wheelbase 2807mm. 2. Powertrain: The LaCrosse offers three engine options: 2.0T, 2.4L, and 3.0L. The US-imported ECOTEC D-VVT 2.4L all-aluminum four-cylinder engine is a new member of General Motors' global ECOTEC engine family. This 16-valve engine features a D-VVT dual electronic variable valve timing system, delivering maximum power of 125kW/6400rpm and maximum torque of 225Nm/4800rpm, with 90% peak torque available as low as 2400rpm. Benefits include the lightweight advantage of the all-aluminum engine, excellent characteristics of D-VVT dual electronic variable valve timing, along with technologies such as multi-point sequential fuel injection (SFI), electronic throttle control (ETC), dual counter-rotating balance shafts, oil-cooled piston jets, maintenance-free automatic adjusting all-steel timing chain, and 32-bit engine control module.

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.
