How to Adjust Engine Timing?

Methods for adjusting engine timing: 1. Rotate the crankshaft and observe the inspection hole on the transmission housing to align the scale line on the flywheel with the pointer on the housing. At this point, the first cylinder piston of the engine is in the timing position; 2. Rotate the camshaft so that the mark on the timing gear of the camshaft aligns with the bottom surface of the valve cover; 3. Align the long side of the rectangular protrusion on the driving end of the oil pump shaft with the direction of the crankshaft. Insert the distributor assembly into the mounting hole, ensuring the groove on its shaft end matches the rectangular protrusion on the oil pump shaft end. Rotate the distributor housing counterclockwise, then secure the distributor with the clamping plate; 4. Position the rotor of the distributor to point at the first cylinder mark on the distributor housing. Cover the distributor cap, designate the side electrode pointed by the rotor as the first cylinder, insert the cylinder wires clockwise, and connect the central high-tension wire and the Hall generator connector; 5. Install the timing belt, start the engine, check the ignition timing, and complete the adjustment.

What are the new regulations for vehicle inspection exemption in 2021?

2021 new regulations for vehicle inspection exemption apply to non-commercial cars, non-commercial small and mini passenger vehicles, implementing a 6-year inspection exemption policy. Below are the detailed explanations: Required documents: For exempted vehicles, after providing the compulsory traffic accident liability insurance certificate, vehicle and vessel tax payment proof, and handling traffic violations and accidents, owners can directly apply for the inspection label from the traffic management department of the public security authority without undergoing safety technical inspection at an inspection institution. Added annual inspection component: Private cars now include a "safety defect recall" component in the online inspection items. If a vehicle has safety issues and is under manufacturer recall, the staff will notify the owner about the recall situation. Clarified exterior inspection scope: The new regulations specify and relax the exterior inspection standards, allowing modifications such as grilles, pedals, roof racks, bumpers, and wheel hubs during exterior inspections. Applying for annual inspection label: Non-commercial small and mini passenger vehicles with 9 seats or fewer (excluding vans) are exempt from inspection for 6 years, but owners must apply for the annual inspection label every 2 years. The exemption is conditional on the vehicle not being involved in any major traffic accidents during this period. If an accident causing personal injury occurs, the vehicle must undergo on-site annual inspection.

How Many Kilometers Can 1 Liter of Gasoline Drive?

A 1.6L displacement car as an example, for long-distance driving, 1 liter of gasoline can approximately drive 16.67 kilometers. If driving on general urban roads, the fuel consumption is about 8 liters per 100 kilometers, so 1 liter of gasoline can approximately drive 12.5 kilometers. Below is the meaning and related introduction of fuel consumption per 100 kilometers: Meaning of fuel consumption per 100 kilometers: Generally, a small car can drive about 10 to 15 kilometers with 1 liter of gasoline. Calculation method: distance driven per liter of gasoline = 100 / fuel consumption per 100 kilometers. Fuel consumption per 100 kilometers refers to the amount of fuel consumed by a vehicle driving 100 kilometers at a certain speed on the road. It is a theoretical indicator of the vehicle. The fuel consumption per 100 kilometers is a value measured by the manufacturer in an objective environment using a dynamometer installed on the vehicle chassis, converted into speed parameters, and then calculated as the theoretical experimental fuel consumption per 100 kilometers of the vehicle model at specified speeds. Considering whether it is close to the economic speed: Since most vehicles approach their economic speed at 90 km/h, most of the publicly announced theoretical fuel consumption is usually the fuel consumption per 100 kilometers at 90 km/h. (Displacement is determined by analyzing the carbon content in the exhaust gas using an exhaust analyzer and the carbon balance method). The most significant expense in vehicle maintenance is fuel costs, so when purchasing a car, it is essential to consider the vehicle's displacement and fuel consumption.

Should I use D+ or D- when going uphill?

When going uphill, greater power is needed. Use D- to downshift the vehicle and obtain higher torque for climbing. Below are some precautions for uphill driving: When climbing for an extended period: Shift to a lower gear in advance. If you attempt to force your way up in a high gear, you will inevitably need to press the accelerator harder, engaging the fuel-saving device. At this point, although the engine speed is high, the increase in vehicle speed is very limited, resulting in a sharp rise in fuel consumption. Therefore, when you feel the car has enough power to drive in a higher gear, shift up to the next higher gear promptly. When driving up a steep slope: You must select an appropriate gear based on the slope conditions to keep the engine sufficiently powerful. If the power is insufficient, downshift quickly and avoid forcing the engine, which could lead to stalling. If you miss the opportunity to shift, you can skip a gear when downshifting. If you cannot engage the gear or the engine stalls, immediately use both the service brake and the parking brake to stop the vehicle forcibly, then restart.

If the rearview mirrors are adjusted differently, will the reference points be different?

Adjusting the rearview mirrors differently will indeed result in different reference points. Below are the methods for adjusting rearview mirrors: Center rearview mirror: The center rearview mirror helps drivers quickly assess road conditions behind them and maintain a safe distance from vehicles at the rear. Adjust the center rearview mirror to be parallel with the horizon and positioned at the center of the mirror surface. The mirror should slightly face the driver to ensure a clear view of vehicles directly behind. Left rearview mirror: Since the left rearview mirror is closer to the driver's side, the driver's blind spot is smaller, providing a wider field of view. The adjustment angle is also relatively smaller compared to the right rearview mirror. Similarly, adjust the horizon to the center of the left rearview mirror, while ensuring that one-quarter of the car body is visible in the mirror. If too little of the car body is visible, it becomes difficult to see vehicles close to the rear; if too much of the car body is visible, it may be hard to clearly see vehicles that are partially parallel. Right rearview mirror: Because the blind spot on the right side is larger for the driver, the adjustment angle differs from that of the left rearview mirror. In this case, adjust the horizon to two-thirds of the right rearview mirror, with one-quarter of the car body visible in the mirror.

Are New Energy Vehicles Afraid of Water?

New energy vehicles are not afraid of being submerged in water, but they should not remain submerged for extended periods. Below is relevant information about new energy vehicles: 1. Introduction: New energy vehicles refer to automobiles that utilize unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new types of onboard power devices), integrating advanced technologies in vehicle power control and driving to form vehicles with advanced technical principles, new technologies, and innovative structures. 2. Classification: New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc.
