By rotating the plunger through the fork or rack, the effective fuel supply stroke of the plunger can be changed, thereby adjusting the fuel supply size. For mechanical pumps, the rack travel inside the fuel injection pump can be adjusted to increase it, thereby enhancing the fuel supply and making the vehicle more powerful. It is recommended to seek professional assistance for adjustments, as improper adjustments may lead to unnecessary issues. For electronically injected vehicles, external adjustments are not possible, and the ECU can be reprogrammed instead.

How to Adjust the Audi Interior Rearview Mirror?

First, adjust the seat to a comfortable position, then adjust the rearview mirror so that your right ear is just at the left edge of the mirror, with the rear window centered in the mirror and the horizon in the mirror also centered. Generally, you should not see yourself in the mirror while driving. The functions of the central rearview mirror are as follows: 1. Observing the rear traffic conditions: When you need to change lanes, first turn on the turn signal, then observe the situation of the vehicles behind you through the interior rearview mirror to ensure safety before changing lanes. If you notice a vehicle behind you has turned on its turn signal or shows an intention to change lanes, be sure to yield. Alternatively, if you see a heavy-duty truck behind you in the mirror, change lanes to avoid danger. 2. Checking the rearview mirror during emergency braking: When you need to brake suddenly due to a situation ahead, if it is safe to do so, check the rearview mirror to see if there is a vehicle following too closely. Based on the distance ahead, you can ease off the brake slightly or consider changing lanes to leave enough space for the vehicle behind you, preventing a chain-rear-end collision.

Left rearview mirror: The horizon should be positioned at the center line, with the edge of the car body occupying 1/4 of the mirror's image. 3. Right rearview mirror: The horizon should be positioned at 2/3 of the mirror, with the edge of the car body occupying 1/4 of the mirror's image. Information about car rearview mirrors is as follows: 1. Rearview mirror: It is a tool that allows the driver to directly obtain information about the rear, side, and lower parts of the car while seated in the driver's seat. 2. Structural principle: The distance between the driver's eyes and the rearview mirror, the size of the rearview mirror, and the radius of curvature of the rearview mirror. These three factors are interrelated. When the distance and size of the rearview mirror are the same, the smaller the radius of curvature of the mirror, the larger the field of view reflected by the mirror. When the radius of curvature of the mirror is the same, the larger the size of the mirror, the larger the field of view reflected by the mirror.

What is the emission standard for a 2016 car?

A 2016 car may comply with either the China IV or China V emission standards. Below is relevant information about 2016 cars and emission standards: 1. Emission standards for 2016 cars: From July 2010 to January 2018, all regions in China implemented the China IV emission standard. Therefore, a 2016 car could be either China IV or China V compliant, as the China V standard was nationally enforced starting January 1, 2017, though some cities adopted it earlier. Car owners can identify their vehicle's emission standard through the invoice, environmental label, or vehicle registration certificate. 2. Information about emission standards: The 'China [X]' emission standard refers to the national stage X motor vehicle pollutant emission standard. The China IV standard has been the longest-implemented standard to date, lasting seven years. Currently, the China VI standard is gradually being introduced. The implementation of the China VI standard has led to China III vehicles facing scrappage, while China V used cars depreciate rapidly due to emission standard changes. On the other hand, stricter emission standards certainly help mitigate air pollution. Moreover, the rapid updates and stringent requirements of emission standards have significantly accelerated the development of new energy vehicles.
