The invention discloses a method for testing carbon deposition of a light automobile valve burning CNG on a rotary drum, and belongs to the technical field of whole automobile testing. The method comprises the following steps: S1, setting test parameters; s2, vehicle inspection; s3, starting a test; s4, checking the engine; s5, testing the vehicle; and S6, the steps S3-S5 are repeated until valve carbon deposition occurs in the engine, engine ECU electronic injection data are adjusted according to the emission and gas consumption test results and the acceleration test results, so that generation of the valve carbon deposition of the engine is reduced, and generation of the valve carbon deposition of the engine in the running process of an automobile combusting CNG is reduced as much as possible while the economic performance and the dynamic performance are guaranteed. According to the invention, the durability test is carried out on the drum of the CNG-fired vehicle, the carbon deposition condition of the valve is checked in stages, and the emission and gas consumption test and acceleration test are carried out on the tested vehicle. And by continuously correcting and adjusting electronic injection data of the ECU of the engine, carbon deposition of the valve of the engine is reduced, so that a series of problems of power reduction, gas consumption increase, even mechanical damage and the like of the CNG vehicle are reduced.

This utility model relates to the field of automotive end cover structure technology, specifically to a lightweight automotive simulator end cover, including an end cover body. A locking block is fixed to the outer top of the end cover body, and a square groove is formed at the top of the end cover body. A sealing plate is fixed within each square groove. An inner rib is fixed to the inner wall of the end cover body, and a mating end is fixed to the middle of the inner side of the end cover body. A friction ring is placed at the bottom of the mating end. A connecting piece is fixed to the edge of the end cover body, and multiple sets of connecting holes are formed in the middle of the connecting piece. The multiple locking blocks, by virtue of their large number, prevent incomplete sealing during screwing due to insufficient screwing ports. The square groove formed on the outer top of the end cover body can engage with external structures, and the inner sealing plate structure forms a triangular inner groove structure inside the square groove, enabling alignment with external structural components and preventing relative sliding.

The disclosure presents a multi-functional truck bed system that can be used with a short bed pickup truck while maximizing the cargo space available. A full functioning pull out drawer / tray with multi-use purposes can handle large loads, roll with minimal effort and have safety features such as anti-tip, anti-fallout, and locking feature to inhibit rolling on a grade. The embodiments include repurposing hardware that consists of the drawer / tray system into a two-place bike holder, a light duty ramp, a table and a step. The hardware is below the drawer / tray so as to maximize the cargo space in the truck bed. The drawer / tray system is non-intrusive, and it can be removed from the truck bed quickly without tools so that a driver can use the truck bed as it was intended.

The invention discloses a plateau-based light automobile unconventional pollutant monitoring method and system, and relates to the technical field of automobile exhaust monitoring, and the method comprises the following steps: obtaining driving information and environment information of a light automobile, the driving information comprises the maximum acceleration of the vehicle, the average acceleration of the vehicle, the high-load driving time, the allowable longest driving time, the average speed of the vehicle, the maximum speed of the vehicle, the total driving distance and the maximum driving distance; the environment information comprises a road gradient, a maximum gradient, a current atmospheric pressure, a current temperature, an average temperature, a temperature range, a road gradient and a maximum gradient; a correction model of the unconventional pollutants is set, the corrected emission amount of the unconventional pollutants is calculated according to the driving information and the environment information, and the unconventional pollutants are NH3 or PN10; and displaying the corrected discharge amount for a user in a chart form, thereby completing monitoring of the unconventional pollutants.

According to the technical scheme, the high-strength light automobile swing arm comprises an alloy support and a lining, the lining is installed in the alloy support through a clamping groove, a locking piece is installed at the position, located at the lining, of the front surface of the alloy support through a screw, and a lightening hole B is formed in the middle of the interior of the alloy support. A lightening hole A is formed in the portion, close to the top, in the alloy support, a supporting frame B is installed in the lightening hole B, and a supporting frame A is installed in the lightening hole A. According to the high-strength light automobile swing arm, the problems that an existing automobile swing arm is integrally arranged, rubber in a lining is prone to aging after being used for a long time, connection abnormal sound is caused, overall replacement is needed, and the replacement and maintenance cost is high are solved, the replacement and maintenance cost of the automobile swing arm is reduced, and therefore the use economical efficiency of the automobile swing arm is improved.
